Growing the Herb Dill
Dill generally grows two to three feet tall. It may be planted in spring or fall. Planted in early spring, dill will produce seeds during the same season. It can also be planted in fall so that the seed germinates on it's own when conditions are right. Sown in drills 15 to 18 inches apart in early spring in warm soil and a sunny place. Thin the seedlings while small to stand 8 to 10 inches asunder. Cultivate frequently. In midsummer cut the ripening heads and spread thinly on sheets. When dry, thresh with light rods. Clean and store the seed in cotton sacks in dry quarters.
Outdoors, in containers (sow direct in final pots, using 8 to 20 seeds per pot), and hydroponic culture.
Dill usually grows to a height of 2 to 3 feet (60 - 90cm).
Dill plants should be spaced between 12 and 15 inches (30 - 38 cm) apart.
