Step-by-Step Growing Guide
Dill is a fast-growing, cool-season annual herb that strongly prefers to be sown directly — transplanting disturbs its taproot and causes immediate bolting. Sow seeds 6mm deep in well-drained, fertile soil at pH 5.8–6.5. Thin seedlings to 15–20cm apart in rows 30cm apart. Direct-sow in spring as soon as soil can be worked, or again in late summer for an autumn crop. Dill requires full sun — 8+ hours daily — to produce strongly aromatic foliage. Water moderately — 2.5cm per week — allowing the top 3cm to dry between waterings; overwatering reduces essential oil concentration. Fertilise lightly with a balanced fertiliser once at sowing — excess nitrogen produces lush but less aromatic growth. Important: never plant dill near fennel, as they cross-pollinate easily and the offspring of both lose their distinct character. Do plant near tomatoes, cabbage, and cucumbers — dill attracts beneficial predatory wasps and hoverflies. Allow plants to self-seed for volunteers the following year.
