When should I sow Dill in the UK?

In the UK, sow Dill from April to July. It is normally sown direct outdoors. Wait until the soil has reached 7°C at seed depth rather than going by the calendar - dill will sit and rot in cold ground.

What soil temperature does Dill need to germinate?

Dill needs a minimum soil temperature of 7°C at seed depth to germinate reliably. Below that, germination is slow and patchy, and seed is more likely to rot than sprout. Measure at around 5cm down, in the morning, rather than trusting air temperature.

How deep and how far apart should I sow Dill?

For Dill, sow it 1cm deep and space plants 30cm apart.

How long does Dill take to grow?

Dill takes roughly 60 days from sowing to harvest. Seed usually germinates in about 10 days.

Is Dill frost hardy?

No. Dill is not frost hardy. Do not put it outside until the risk of frost has passed in your area, and be ready to fleece it if a late frost is forecast.

Sowing data cross-checked against RHS growing guides and UK seed-merchant catalogues. Soil temperatures are the minimum for reliable germination, measured at seed depth.
