Dill

Growing Dill

Bouquet, Long Island Mammoth.

See your seed dealer for the most recent variety recommendations.

 

A well-drained sandy loam is suitable.

 

Seeds are sown in shallow drills 30 cm apart. The seedlings are thinned to 20 cm apart when about 7.5 cm high. For use with dill pickles, seed 1 week earlier than pickling cucumbers.

A soil test is necessary to determine phosphate and potash requirements. Use the Vegetable Production Guide: Nutrient Management (PDF) for recommendations based on soil test results. The crop should not be over-fertilized with nitrogen or it will produce excess leaves and stalk at the expense of seed.

Prior to planting broadcast and incorporate nitrogen at 40 kg/ha (16 kg/acre) and all the required phosphate and potash.

 For use with dill pickles, cut or pull stalks after the majority of seed pods have formed but are still green.

Dill Insect Management

 

To monitor aphids on dill, it is essential to check plants when they are 2.5 cm tall and treat at intervals thereafter when aphids are seen. To check for aphids, shake plants vigorously over a piece of paper or over the hand. If aphids are present, they will fall off the plant onto the paper or hand. Neudosan and Opal are registered for control of aphids in herbs.

These are green worms with yellow stripes which will grow to over 5 cm long. They are never very numerous so it may be practical to hand-pick the worms and destroy them. No chemical controls are registered.
