Dill

Anethum graveolens

Dill gives you feathery leaves and, later on, seeds. It has one long main root and hates being moved. So sow it where it will grow, a little at a time every few weeks from mid-spring to midsummer. Like coriander, it bolts in hot, dry weather, which means it flowers too soon.

Looking after it

Water: Normal watering suits dill. Water it in dry spells, because dry soil makes it flower early and stop making leaves. Pots dry out quickly in warm weather. Feeding: It needs little food. In garden soil or fresh compost, you don't need to feed it at all.

Picking and keeping

You can start picking leaves about six weeks after sowing. Take a few at a time and leave at least a third of the plant. For seed, cut the heads in late summer when they are dry and brown. Hang them upside down in a paper bag. Fresh leaves wilt fast and don't keep well, even in the fridge. Use them soon or dry them. Dried leaves and seeds keep in an airtight jar.

What can go wrong

Bolting. In hot, dry weather the plants flower early and stop making leaves. Water in dry spells and sow again every few weeks. If you only want leaves, cut off the flower stems.
Aphids. Small green or black insects cluster on the soft shoots and leaves. Rub or wash them off. Leave the ladybirds alone to eat the ones you miss.
Slugs and snails. In damp weather they eat the tender seedlings. Check after dark and pick them off.
