Learning Download: How to Grow Tarragon
Tarragon is a hardy herb usually grown for its leaves and their aromatic flavor. Tarragon plants can reach up to 3 feet tall. The herb has long, light green leaves and yellow or white flowers.
Before Planting: Tarragon grows best in full sun in soil with a pH of 6.5 to 7.5. Because of its great root system, tarragon can thrive in poorer soils.
Planting: Begin tarragon seeds indoors in April and sow four to six seeds per pot in moist, composted potting soil. Once seedlings sprout a few inches, thin them to one seedling per pot. Transplant tarragon seedlings outdoors once the last frost has passed. Upon transplanting them outside, space tarragon plants 18 to 24 inches apart if planting in the garden.
Watering: Tarragon does not require frequent watering unless there is a drought.
Fertilizer: Prior to planting tarragon outdoors or transplanting it, mix 1 to 2 inches of compost into the top 6 inches of soil and add ½ tablespoon of an all-purpose fertilizer per square foot. After planting, there is no need to fertilize as tarragon’s flavor will intensify in low-nutrient soil.
Days to Maturity: Both the leaves and the flowers of tarragon can be harvested and are usually ready for harvest in the late summer. (See variety for days to maturity)
Harvesting: Harvest tarragon in the morning and do so by stripping the lower leaves from the stem first.
Tips: Divide the tarragon plants every three to five years to ensure its best growth.
