Dill, Anethum graveolens, or dill weed, is a delicious, easy-to-grow herb used mostly with fish dishes, although it was once a popular remedy for coughs and headaches.


As well as its medicinal and culinary uses, it is also a beautiful ornamental plant with feathery leaves, similar to fennel with umbels of yellow flowers. Dill is also a magnet for different kinds of wildlife.

Dill flowers will attract bees, hoverflies and butterflies and caterpillars of the beautiful European swallowtail butterfly, Papilio machaon, will eat the leaves.

Sowing dill seeds

How to grow dill from seed

Sow dill seeds outdoors directly into well prepared soil in a sheltered, sunny position. Sow seeds thinly in rows 1cm deep. Dill can also be sown directly in large pots. Make regular sowings for a continuous supply of fresh leaves through the summer. Dill tends to bolt if its roots have been disturbed on planting. But if you want to get a head start, you can sow seeds under cover a little earlier in the season, using plug trays. Plant out the plugs after all risk of frost has passed.

Looking after dill

When seedlings are large enough to handle, thin them out to 20cm apart. Keep plants well-watered, particularly during hot, dry weather. Keep weed-free to stop any competition for water and nutrients. Plants may need additional support from canes, as strong winds can flatten them. Dill does not normally need feeding, but an occasional liquid feed of a balanced fertiliser can give the plant a boost.

Storing dill

The leaves are best used fresh, but can be frozen for later use. Dill seeds should be stored in an airtight container.

Dill: problem solving

As well as the usual temptation for slugs and snails, young dill plants can be plagued by greenfly. These sap sucking aphids will coat the plant with their sticky honeydew. The best method of treatment is to squash the colonies of greenfly with your fingers.

Dill is also prone to bolting and flowering prematurely. Keep plants well watered and avoid root disturbance to help prevent this.
