Learning Download: How to Grow Hyssop
Hyssop blooms in spikes of blue, pink and red flowers and it attracts pollinators to the garden. This flowering herb is commonly grown for its leaves.
Before Planting: Sow the hyssop seeds indoors eight to 10 weeks before the last frost of the season.
Planting: Transplant the seedlings into the garden after the last frost and space the plants about 6 to 12 inches apart.
Watering: Provide 1 inch of water once or twice weekly.
Fertilizer: Prior to transplanting the seedlings to the garden, amend the soil with compost or organic material like aged animal manure.
Days to Maturity: Hyssop will reach its maturity in 75 to 85 days from planting.
Harvesting: Cut in the morning once the dew has dried. Then, hang upside down in a dark and well-ventilated area.
Tips: Hyssop needs to be pruned, so if you have a well-established plant, trim it back in the early spring.
