When should I sow Land Cress in the UK?

In the UK, sow Land Cress from March to August. It is normally sown direct outdoors. Wait until the soil has reached 5°C at seed depth rather than going by the calendar - land cress will sit and rot in cold ground.

What soil temperature does Land Cress need to germinate?

Land Cress needs a minimum soil temperature of 5°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 Land Cress?

For Land Cress, sow it 1cm deep and space plants 15cm apart.

How long does Land Cress take to grow?

Land Cress takes roughly 63 days from sowing to harvest. Seed usually germinates in about 7 days.

Is Land Cress frost hardy?

Yes. Land Cress is frost hardy and will stand through UK frosts, so it can be left out over winter in most of the country.

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.
