Caring for Dill

Dill has moderate water needs. Water regularly during dry spells, especially while plants are young and establishing their taproots. Once mature, dill is reasonably drought-tolerant, but prolonged dryness will cause it to bolt prematurely and reduce leaf quality. Aim to keep the soil evenly moist rather than saturated; overwatering or waterlogged conditions can lead to root rot and fungal issues. In high summer, water in the early morning or evening to reduce evaporation. Feeding is not necessary for dill. This herb grows well in average soil and excessive nitrogen will promote lush, soft growth that is more prone to pest damage and has less flavour. If your soil is very poor, a light application of general-purpose organic fertiliser or well-rotted compost at planting time is sufficient. Avoid feeding once plants are growing. Dill is an annual and will not survive winter, so there is no need for overwintering protection. Allow a few plants to self-seed if you want volunteers next spring, though these may appear later than deliberately sown crops. Clear spent plants in autumn to prevent debris harbouring pests or disease. Aphids are the most common pest, clustering on young shoots and flower stems. Spray them off with water or encourage natural predators like ladybirds and hoverflies. Carrot root fly can occasionally affect dill, as both belong to the Apiaceae family; growing dill away from carrots reduces risk. Powdery mildew may appear in dry conditions or on overcrowded plants; thin seedlings properly and water at the base to keep foliage dry. Mulching is generally unnecessary, but a light layer of compost in spring helps retain moisture and suppress weeds without smothering shallow roots.
