How To Grow Blue Jacob's Ladder: Sow Jacob's Ladder seeds indoors 6 - 8 weeks before the predicted last frost date or directly outdoors after frost season is over and night time temps are warm. Surface sow Jacob's Ladder flower seeds on good seed starting mix, gently pressing the herb seeds into the mix and lightly covering. Moisten the mix and keep it moist until germination begins. Light is required for best germination. When the seedlings are established, pick out each seedling as it becomes large enough to handle and transplant into 3 inch pots. Gradually acclimatize the Jacob's Ladder seedlings to outdoor conditions for 10 - 15 days before planting out into their permanent positions, space 12 - 18 inches apart. Jacob's Ladder care includes deadheading spent blooms to prolong bloom time.
