Oyster Plant (Mertensia martima dolphin) - Also known as Oyster Leaf and Sea Bluebells. Mertensia maritima has its unique name because it gives off a faint smell of mushrooms and when eaten it tastes vaguely of oysters. The chemical that gives this plant the oyster-like odor when its leaves are crushed is dimethyl sulphide, a compound that is noted for being a major part of the odor profile of raw oysters.

  • Edible variety for pots and hanging baskets or in the garden
  • Plant height mature plants 6 inches in pots, 10 inches in the garden
  • Ornamental value
  • Salt tolerant
  • Leaves have an oyster- like taste
  • Suitable for salads, garnish and mixed containers

If raw oysters are your thing, this is the herb plant choice for you. Beautiful glaucous blue-green leaves on sprawling stems tipped in small sky blue flowers. This likes ample nutrition. Perennial and dormant in winter. This is a plant of just above high tide line on cold northern hemisphere beaches from Maine to Greenland and Japan to Alaska so if you have a cool to cold garden, here you go.The fleshy leaves of this low-growing shore plant are rich in flavor, which is comparable to oysters, anchovies, mushrooms, and borage depending on your palette.

Oyster leaf needs cold to germinate and its seeds require stratification and germinate rather irregularly, distributed over a longer period of time. Sow from October to February directly outdoors. Only sparsely cover with soil. Since this plant is very popular with snails, it should be cultivated in pots. Oyster leaf loves sunny locations and fresh, permeable, slightly sandy soils.

Verbascum (Verbascum Phoenicium Hybrids Mix) - This free flowering mix grown from Verbascum seeds will give your garden weeks of lovely colors. Commonly called Purple Mullein, this plant has dark green, crinkly leaves and beautiful spikes of papery-thin, round 5 - petaled blooms in shades of white, rose, and violet. The Purple Mullein plant starts blooming from the bottom of the spike and proceeds upward, opening one by one. Mullein flowers look lovely in a mixed border, and they can bloom from late spring up until the first frost. It is both deer and rabbit resistant, and butterflies love it! Verbascum flowers are excellent for cutting as well. Also considered to be a medicinal herb, the Mullein herb has diuretic, analgesic, expectorant, and antiseptic properties.

How To Grow Mullein From Seed: Plant Mullein seeds indoors 6 - 8 weeks before last frost date. Lightly press the Verbascum flower seeds into the soil, but do not cover with soil since the seeds need light to germinate. Keep constantly moist, not wet, and the herb seeds will germinate in 14 - 21 days. For outdoor sowing, wait until frost danger has passed, and sow Purple Mullein seeds directly into prepared seed bed. Spacing should be about 18 - 24 inches apart. Verbascum Mullein will bloom the first year if the flower seeds are sown early enough in the season. Flowers can be left on to self-seed or can be deadheaded to encourage more blooming.

How To Grow

Arnica is an easy plant to grow. If planting directly outdoors, sow the seeds loosely over prepared soil in the late summer: cover lightly with fine soil or sand. If starting the seeds indoors, plant them in pots a few months before the growing season begins. Place in a bright area. Germination usually occurs in a month, but can sometimes take longer. Indoor seedlings should be transplanted outdoors after all danger of frost has passed. Well-established plants can be propagated in the spring by divisions or cuttings.

  • Environment: full sun to partial shade
  • Soil: acidic
  • Sowing rate: 2-3 seeds per plant
Useful Herb

Plant Specifications

Arnica Montana (also known as Mountain Tobacco) is a flowering perennial herb that grows in USDA zones 5 through 8. It is very useful medicinally, and is traditionally employed as a pain-killer.

  • Bloom color: yellow
  • Bloom season: May through June
  • Plant height: 20 inches

Mountain Tobacco (Arnica Montana) - Also called Leopard's Bane, Wolf's Bane, Mountain Tobacco, and Mountain Arnica. Arnica montana is sometimes grown in herb gardens and has long been used medicinally. This daisy-like mountain flower can be used for: bruises, sprains, soreness and swelling/muscle spasms from sports activity; arthritis set off by seasonal change; general muscle and joint pain. Some people are sensitive to the compound helenalin found in arnica. If you develop a mild rash, then you are probably helenalin-sensitive and should stop using arnica.

As an herb, arnica is usually used topically (on the skin) because it can cause serious side effects when taken by mouth. Oral homeopathic remedies do contain arnica, but they use a diluted form that is not considered dangerous. If you have any question about whether you have the herbal or homeopathic form of arnica, talk to your doctor.

Common Questions

Q

Which herbs can thrive in the kitchen?

A

Not all herbs are suitable for indoor growth. Herbs with woody, bushy growth, like rosemary are too large for indoor herb gardens. Consider other more suitable herbs for an indoor kitchen garden, such as chives, oregano, thyme, dill, mint, basil, cilantro, sage and savory. Each herb has specific growing needs, so ensure to provide the right amount of light, humidity, and air circulation. If using a single large container, ensure that all plants require similar amounts of sunlight and water. For instance, chives and cilantro may not need as much sunlight as dill and oregano.

Q

What are good companion plants for herb gardens?

A

Pairing herbs based on watering requirements, like planting lavender with thyme or basil with chives, is ideal for maintaining the health of both plants. Avoid companion planting with catnip, lemon balm and mint as they should be grown in separate pots due to their rapid spreading nature that can overtake other plants in your indoor herb garden.

Q

When do I establish an indoor herb garden?

A

Create a kitchen herb garden by propagating cuttings from your outdoor plants as the weather cools in the fall. If you opt to sow your indoor herb garden from purchased seeds, begin a few weeks before the anticipated first frost of the season. Most herbs can be harvested within a few weeks, so there is no need to plant too far in advance.

Q

Do kitchen herbs need full sun?

A

Most herbs need 6 hours of sunlight a day to thrive. If you do not have this type of light available in your kitchen, consider a grow light that will run 14-16 hours per day 6 to 12 inches above your plants. NOTE: Rotate herbs periodically when grown in windows to let each part of the plant receive sunlight.

Q

What time of year should you plant herbs?

A

Herbs grown in indoor gardens can be planted any time of year. Many gardeners prefer to grow their herbs outdoors during the summer growing season, and then move them to their indoor garden before the first frost of fall. If you prefer to start your seeds outdoors, you will need to wait until after danger of frost in the spring or start your seeds indoors 6 -8 weeks before last frost and transplant in your garden after danger of frost.

Q

Do herbs come back every year?

A

Perennial herbs will come back each year when planted in the correct zone or grown indoors during the cold winter months. Popular perennial herbs are oregano, parsley, sage, fennel, chives, lavender, thyme and mint varieties.

Q

How do I know when my herbs need watered?

A

Allow the soil to dry out just slightly before watering your herbs again. Give your indoor herb garden a dose of diluted water-soluble fertilizer every 2 weeks or so. Too much food will compromise the taste of the herbs. It is also beneficial to provide adequate humidity. If the indoor air is especially dry – which is often the case in regions with cold winters. Set the herbs pots on trays of stones. Fill the trays with water but keep the level below the drainage holes of your pots.

Q

When do I water my outdoor herb garden?

A

Different herb plants will need different amounts of water so keep this in mind when planting your garden and keep similar plants together to simplify watering. Watering is best done in the early morning hours when temperatures are cooler. Many herbs are hardy. They can tolerate soil that is moderately dry. You want to keep an eye out for wilting when the soil is wet. Ideally, your herbs should make quick use of the water you give them. Saturated soil is not what you are after. Pay close attention to the coloration of the leaves on your herbs. Yellow leaves can be a sign of too much water, and so can black leaves. If you spot any mildew or fuzz on the herbs, too much moisture can be the problem.

Q

How do I harvest my herbs?

A

Trim back flowering sections before they bloom for healthier leaves. Prune new growth on young plants weekly to encourage a fuller mature plant. Snip herbs for harvest when they are just a few inches tall. Pruning back the herbs often means a larger, longer harvest. Cut the new growth back at least one per week, even if you are not using the herbs in recipes (see drying and freezing page if you do not want to waste your harvest). Long stems that are about to set flower buds should be trimmed off as they appear.

Q

What do I need to start an indoor herb garden?

A

Common tools needed for an indoor herb garden are: garden trowel, scissors for snipping, stones (optional). Materials for your herbs plants include seed, pots, potting soil, cactus potting soil (optional), pots or trays, fertilizer and a grow light if you do not have adequate sunlight of at least 6 hours per day for your plants.

Q

How do I prepare my containers for planting?

A

Choose large, deep containers with drainage holes to accommodate fast-growing herbs. Fill the container with potting mix leaving about ½ inch clear at the top. Use standard commercial potting soil for most herbs but blend in cactus potting mix for herbs native to the Mediterranean, such as thyme and oregano which prefer dryer soils.

Q

Can I put my indoor herb containers outside?

A

Yes! Move your potted herbs to the patio or deck when the weather warms in the spring and for a boost of sunshine.

Q

How do I know when my herbs need larger containers?

A

When roots begin to emerge through the drainage holes of its container, it is time to repot the herbs. Replace the potting mix; the organic material in the potting mix breaks down over time. Remove any plants with woody or thickened stems and replace them with new seeds or seedlings.

Q

Do herbs need fertilizer?

A

The short answer is yes. However, not all herbs have the same fertilizer needs. Herbs roughly fall into two groups. 1. Slow-growing herbs with small leaves or needles and fibrous, woody stems that are native to the mediterranean where they grow culinary lavender, month, marjoram, oregano, rosemary, sage, savory, tarragon and thyme. 2. Fast-growing herbs with larger, thinner leaves. These can be annuals such as basil, borage, cilantro, chervil and dill; bi-annual herbs such as parsley or perennials such as chives. Herbs in the first group generally need less fertilizer than herbs in the second group.

Q

What type of nutrients do herbs need?

A

Start out by planting herbs in healthy soil rich in organic matter. In addition, they will benefit from an organic complete, slow-release fertilizer containing equal amounts of macronutrients nitrogen, phosphorus and potassium. A slow-release fertilizer is especially important if your garden has sandy soil because nutrients wash out quickly. To give fast-growing herbs that you harvest often an extra boost, you can also apply fish emulsion, an organic fertilizer that is high in nitrogen, with an NPK ratio of 4-1-1 or 5-1-1.

Q

How often should I fertilize my herbs?

A

The frequency of fertilization follows the growth pattern of the herbs. In soil of average fertility, it is usually sufficient to apply a balanced fertilizer in the spring when they break dormancy, or when the new growing season starts. For other herbs, a light monthly application of a slow-release complete fertilizer should be enough – unless the leaves start to look yellow, which may be a sign of nitrogen deficiency. In that case, applying fish emulsion is a quick fix but before you reach for the fertilizer bottle, rule out that the yellowing of leaves is not caused by something else.

Q

How do I fertilize my herbs in a container?

A

Herbs grown in containers need fertilizer applications more often, because with frequent watering that container plants require, the fertilizer in the potting mix washes out more quickly. Just as with sandy soil, it is important to use slow-release fertilizer. The roots of container plants are in a confined space, unlike herbs grown in the garden or raised beds, which can lead to over fertilization if you are not careful. Organic fertilizers are recommended over synthetic which often contain a high level of salts that can build up in the container over time. To prevent this, it is best to use half the strength of the fertilizer amount specified on the label for any type of fertilizer.

Q

Is it possible to overfertilize herbs?

A

Adding too much fertilizer to herbs usually leads to an excess of nitrogen, which has undesirable results especially for slow-growing herbs. For basil and other thin-leaved herbs, the fast leaf growth induced by nitrogen is fine because you want your plants to be lush. For rosemary and other Mediterranean herbs however, rapid growth means that there is less concentration of essential oils causing the herbs to become less aromatic and have weaker flavor.

Q

How do I prepare garden soil before planting an herb garden?

A

Once you have picked the location for growing your herb garden, you will need to prepare the soil. If the soil is sandy or clay heavy, add plenty of compost. Even if your soil is in pretty good condition, working some compost into the soil will help provide nutrients to the herbs while they are growing.

Q

Can I harvest my herbs too often?

A

Many times, when a new gardener is starting an herb garden, they are afraid that harvesting the herbs frequently will hurt them. The opposite is true. Frequent harvesting of herbs will result in the herb plant producing more and more foliage, which increases the amount you are able to harvest. At the end of the season, you can dry or freeze your herb harvest to enjoy home grown herbs all year long.

Q

I don’t have a good sunny spot outdoors for my herb garden, what can I do?

A

If your yard is mostly shaded, there is not much you can do to change that, but you can pick shade friendly herbs. Parsley, sweet woodruff and mint are good examples of herbs that don’t require as much light. If you are growing plants in low light, manage your expectations. Your herbs will grow but will be slow and results less impressive.

Q

My container soil is staying wet, what do I do?

A

Choose a container that allow for water to drain. If you over water or if it rains too much a good pot will allow the water to flow to the bottom without soaking and rotting the roots of your plants. You can use rocks or pottery shards to fill the bottom of the container to help with drainage. This applies outdoors too. If your herbs constantly have wet feet, they won’t thrive. Either plan when planting your garden and add some sand for drainage or pick plants that don’t mind wet roots as much.

Q

My herbs plants are going to seed, why?

A

The short answer is you are not pruning enough. To prevent rapid growth and encourage a bushy habit, be sure to prune your herb plants regularly. The more you pick off your stems and leaves the longer your herb plant will remain in its production cycle. If you start to see flower heads, snip them right away. When you fail to cut back the plant, it is likely to go to seed and complete its lifecycle. Once that happens, many plants die back. Keep cutting and pinching back flowers to prevent this from happening.

Q

Should I throw away my seeds on their expiration date?

A

Seeds do not have an expiration date, rather they are a sell by date just like food. The dates on seed packages are guidelines to help you know when your seeds are getting old, but it does not mean you need to toss them. Every plant is different. Some seeds last longer than others. Most seeds, if kept cool and dry, will last 2 – 3 years. If you are unsure test them out by growing microgreens.

Seeds do not have an expiration date, rather they are a sell by date just like food. The dates on seed packages are guidelines to help you know when your seeds are getting old, but it does not mean you need to toss them. Every plant is different. Some seeds last longer than others. Most seeds, if kept cool and dry, will last 2 – 3 years. If you are unsure test them out by growing microgreens.

Common Questions

Q

What are common pest problems with society garlic?

A

When grown outdoors, society garlic plants typically do not attract insects. However, those cultivated in greenhouses or kept indoors during winter may draw aphids or whiteflies. To address these pest issues, use a strong spray of water to rinse the plant and apply insecticidal soap. Additionally, to deter soft-bodied pests, sprinkle a layer of crushed eggshells or another gritty substance around the base of outdoor plants.

Q

Do I need to fertilize my society garlic plants?

A

To enhance drainage and promote blooming, incorporate two to three inches of organic compost or a general-purpose fertilizer into the soil annually in early spring.

Q

How much water should I use caring for my plants?

A

Water your plants gradually and thoroughly, especially during potential droughts in spring or summer. Be cautious not to overwater, as tubers can easily rot when planted in excessively wet or soggy soil. For optimal growth, garlic plants should be watered consistently throughout their growing season, allowed to dry out a bit while blooming, and nearly completely dried out during their winter dormancy.

Q

What are some ways to use society garlic plants around my landscape?

A

These can be stunning in sunny borders, beds, rock gardens, cottage gardens, herb gardens or has edging plants best planted in groups. They also do well in containers.

Milk Thistle (Silybum Marianum) - Milk Thistle seeds grow easily and produce a hardy biennial that is native to the Mediterranean area and has naturalized throughout North America. It is very impressive as an ornamental herb plant. It is tall and stately with large, mottled, spiny foliage that contains a milky sap-like substance and large, thistle-like heads of rose-pink flowers. Milk Thistle herb plants do re-seed themselves, so it is recommended to deadhead the flowers before they set seed. Other common names for this herb plant are Mediterranean Milk Thistle, Marian Thistle, St Mary's Thistle and Holy Thistle.

Milk Thistle is a well-known medicinal herb with a long history of use in the treatment of liver and gallbladder ailments. It is the Milk Thistle seeds that are used medicinally, and they contain silymarin which is a flavonoid. The Milk Thistle herb may have a protective and regenerative effect on liver cells. As a nutritional supplement to support liver function, the seeds can be ground and added to hot cereals or other whole grain dishes.

How To Grow Milk Thistle From Herb Seeds: Grow Milk Thistle seeds directly in the herb garden. Prepare a seedbed and sow the herb seeds in the spring when temperatures have warmed. The Milk Thistle plants prefer full sun, but they are not picky about soils. They are also tolerant of dry and wet soils.

Common Questions

Q

Which herbs can thrive in the kitchen?

A

Not all herbs are suitable for indoor growth. Herbs with woody, bushy growth, like rosemary are too large for indoor herb gardens. Consider other more suitable herbs for an indoor kitchen garden, such as chives, oregano, thyme, dill, mint, basil, cilantro, sage and savory. Each herb has specific growing needs, so ensure to provide the right amount of light, humidity, and air circulation. If using a single large container, ensure that all plants require similar amounts of sunlight and water. For instance, chives and cilantro may not need as much sunlight as dill and oregano.

Q

What are good companion plants for herb gardens?

A

Pairing herbs based on watering requirements, like planting lavender with thyme or basil with chives, is ideal for maintaining the health of both plants. Avoid companion planting with catnip, lemon balm and mint as they should be grown in separate pots due to their rapid spreading nature that can overtake other plants in your indoor herb garden.

Q

When do I establish an indoor herb garden?

A

Create a kitchen herb garden by propagating cuttings from your outdoor plants as the weather cools in the fall. If you opt to sow your indoor herb garden from purchased seeds, begin a few weeks before the anticipated first frost of the season. Most herbs can be harvested within a few weeks, so there is no need to plant too far in advance.

Q

Do kitchen herbs need full sun?

A

Most herbs need 6 hours of sunlight a day to thrive. If you do not have this type of light available in your kitchen, consider a grow light that will run 14-16 hours per day 6 to 12 inches above your plants. NOTE: Rotate herbs periodically when grown in windows to let each part of the plant receive sunlight.

Q

What time of year should you plant herbs?

A

Herbs grown in indoor gardens can be planted any time of year. Many gardeners prefer to grow their herbs outdoors during the summer growing season, and then move them to their indoor garden before the first frost of fall. If you prefer to start your seeds outdoors, you will need to wait until after danger of frost in the spring or start your seeds indoors 6 -8 weeks before last frost and transplant in your garden after danger of frost.

Q

Do herbs come back every year?

A

Perennial herbs will come back each year when planted in the correct zone or grown indoors during the cold winter months. Popular perennial herbs are oregano, parsley, sage, fennel, chives, lavender, thyme and mint varieties.

Q

How do I know when my herbs need watered?

A

Allow the soil to dry out just slightly before watering your herbs again. Give your indoor herb garden a dose of diluted water-soluble fertilizer every 2 weeks or so. Too much food will compromise the taste of the herbs. It is also beneficial to provide adequate humidity. If the indoor air is especially dry – which is often the case in regions with cold winters. Set the herbs pots on trays of stones. Fill the trays with water but keep the level below the drainage holes of your pots.

Q

When do I water my outdoor herb garden?

A

Different herb plants will need different amounts of water so keep this in mind when planting your garden and keep similar plants together to simplify watering. Watering is best done in the early morning hours when temperatures are cooler. Many herbs are hardy. They can tolerate soil that is moderately dry. You want to keep an eye out for wilting when the soil is wet. Ideally, your herbs should make quick use of the water you give them. Saturated soil is not what you are after. Pay close attention to the coloration of the leaves on your herbs. Yellow leaves can be a sign of too much water, and so can black leaves. If you spot any mildew or fuzz on the herbs, too much moisture can be the problem.

Q

How do I harvest my herbs?

A

Trim back flowering sections before they bloom for healthier leaves. Prune new growth on young plants weekly to encourage a fuller mature plant. Snip herbs for harvest when they are just a few inches tall. Pruning back the herbs often means a larger, longer harvest. Cut the new growth back at least one per week, even if you are not using the herbs in recipes (see drying and freezing page if you do not want to waste your harvest). Long stems that are about to set flower buds should be trimmed off as they appear.

Q

What do I need to start an indoor herb garden?

A

Common tools needed for an indoor herb garden are: garden trowel, scissors for snipping, stones (optional). Materials for your herbs plants include seed, pots, potting soil, cactus potting soil (optional), pots or trays, fertilizer and a grow light if you do not have adequate sunlight of at least 6 hours per day for your plants.

Q

How do I prepare my containers for planting?

A

Choose large, deep containers with drainage holes to accommodate fast-growing herbs. Fill the container with potting mix leaving about ½ inch clear at the top. Use standard commercial potting soil for most herbs but blend in cactus potting mix for herbs native to the Mediterranean, such as thyme and oregano which prefer dryer soils.

Q

Can I put my indoor herb containers outside?

A

Yes! Move your potted herbs to the patio or deck when the weather warms in the spring and for a boost of sunshine.

Q

How do I know when my herbs need larger containers?

A

When roots begin to emerge through the drainage holes of its container, it is time to repot the herbs. Replace the potting mix; the organic material in the potting mix breaks down over time. Remove any plants with woody or thickened stems and replace them with new seeds or seedlings.

Q

Do herbs need fertilizer?

A

The short answer is yes. However, not all herbs have the same fertilizer needs. Herbs roughly fall into two groups. 1. Slow-growing herbs with small leaves or needles and fibrous, woody stems that are native to the mediterranean where they grow culinary lavender, month, marjoram, oregano, rosemary, sage, savory, tarragon and thyme. 2. Fast-growing herbs with larger, thinner leaves. These can be annuals such as basil, borage, cilantro, chervil and dill; bi-annual herbs such as parsley or perennials such as chives. Herbs in the first group generally need less fertilizer than herbs in the second group.

Q

What type of nutrients do herbs need?

A

Start out by planting herbs in healthy soil rich in organic matter. In addition, they will benefit from an organic complete, slow-release fertilizer containing equal amounts of macronutrients nitrogen, phosphorus and potassium. A slow-release fertilizer is especially important if your garden has sandy soil because nutrients wash out quickly. To give fast-growing herbs that you harvest often an extra boost, you can also apply fish emulsion, an organic fertilizer that is high in nitrogen, with an NPK ratio of 4-1-1 or 5-1-1.

Q

How often should I fertilize my herbs?

A

The frequency of fertilization follows the growth pattern of the herbs. In soil of average fertility, it is usually sufficient to apply a balanced fertilizer in the spring when they break dormancy, or when the new growing season starts. For other herbs, a light monthly application of a slow-release complete fertilizer should be enough – unless the leaves start to look yellow, which may be a sign of nitrogen deficiency. In that case, applying fish emulsion is a quick fix but before you reach for the fertilizer bottle, rule out that the yellowing of leaves is not caused by something else.

Q

How do I fertilize my herbs in a container?

A

Herbs grown in containers need fertilizer applications more often, because with frequent watering that container plants require, the fertilizer in the potting mix washes out more quickly. Just as with sandy soil, it is important to use slow-release fertilizer. The roots of container plants are in a confined space, unlike herbs grown in the garden or raised beds, which can lead to over fertilization if you are not careful. Organic fertilizers are recommended over synthetic which often contain a high level of salts that can build up in the container over time. To prevent this, it is best to use half the strength of the fertilizer amount specified on the label for any type of fertilizer.

Q

Is it possible to overfertilize herbs?

A

Adding too much fertilizer to herbs usually leads to an excess of nitrogen, which has undesirable results especially for slow-growing herbs. For basil and other thin-leaved herbs, the fast leaf growth induced by nitrogen is fine because you want your plants to be lush. For rosemary and other Mediterranean herbs however, rapid growth means that there is less concentration of essential oils causing the herbs to become less aromatic and have weaker flavor.

Q

How do I prepare garden soil before planting an herb garden?

A

Once you have picked the location for growing your herb garden, you will need to prepare the soil. If the soil is sandy or clay heavy, add plenty of compost. Even if your soil is in pretty good condition, working some compost into the soil will help provide nutrients to the herbs while they are growing.

Q

Can I harvest my herbs too often?

A

Many times, when a new gardener is starting an herb garden, they are afraid that harvesting the herbs frequently will hurt them. The opposite is true. Frequent harvesting of herbs will result in the herb plant producing more and more foliage, which increases the amount you are able to harvest. At the end of the season, you can dry or freeze your herb harvest to enjoy home grown herbs all year long.

Q

I don’t have a good sunny spot outdoors for my herb garden, what can I do?

A

If your yard is mostly shaded, there is not much you can do to change that, but you can pick shade friendly herbs. Parsley, sweet woodruff and mint are good examples of herbs that don’t require as much light. If you are growing plants in low light, manage your expectations. Your herbs will grow but will be slow and results less impressive.

Q

My container soil is staying wet, what do I do?

A

Choose a container that allow for water to drain. If you over water or if it rains too much a good pot will allow the water to flow to the bottom without soaking and rotting the roots of your plants. You can use rocks or pottery shards to fill the bottom of the container to help with drainage. This applies outdoors too. If your herbs constantly have wet feet, they won’t thrive. Either plan when planting your garden and add some sand for drainage or pick plants that don’t mind wet roots as much.

Q

My herbs plants are going to seed, why?

A

The short answer is you are not pruning enough. To prevent rapid growth and encourage a bushy habit, be sure to prune your herb plants regularly. The more you pick off your stems and leaves the longer your herb plant will remain in its production cycle. If you start to see flower heads, snip them right away. When you fail to cut back the plant, it is likely to go to seed and complete its lifecycle. Once that happens, many plants die back. Keep cutting and pinching back flowers to prevent this from happening.

Q

Should I throw away my seeds on their expiration date?

A

Seeds do not have an expiration date, rather they are a sell by date just like food. The dates on seed packages are guidelines to help you know when your seeds are getting old, but it does not mean you need to toss them. Every plant is different. Some seeds last longer than others. Most seeds, if kept cool and dry, will last 2 – 3 years. If you are unsure test them out by growing microgreens.

Common Questions

Q

How can I encourage my Agastache to continue to bloom?

A

Trim the tips of the growth in spring when the plants reach around 6 inches tall to promote branching. Regularly remove spent flowers during the growing season to ensure continuous blooming.

Q

Do I need to deadhead my Agastache?

A

Deadheading agastache flowers promotes more blooms and helps manage the plant's tendency to self-seed. While not essential, removing spent flowers maintains plant neatness and prevents excessive self-seeding by agastache.

For further pruning, consider whether you are cultivating agastache as a perennial or annual plant. For perennials, trim back about one-third of the plant in spring to stimulate fresh growth. Continue pinching and deadheading until midsummer, as new growth is sensitive to cold and could jeopardize the plant's survival in winter. If growing agastache as an annual, ongoing pinching and deadheading throughout the season is suitable.

Q

Are agastache invasive?

A

If you have planted hummingbird mint, or any other type of agastache, in your garden, you may notice that it spreads similar to mint. This plant tends to self-seed abundantly, but removing the seedlings is a simple task. Additionally, you can prevent seeds from dropping by removing the spent flowerheads. Despite its tendency to spread, agastache is not classified as invasive, especially if you choose a variety native to your region.

Q

Is it easy to grow agastache from seed?

A

Agastache can be grown from seed quite easily, but the seeds need cold stratification and light for germination. For this reason, it is recommended to start agastache seeds in the fall or winter with minimal covering.
