When should I sow Microgreens Mix in the UK?

In the UK, sow Microgreens Mix from January to December. It is normally sown direct outdoors. Wait until the soil has reached 10°C at seed depth rather than going by the calendar - microgreens mix will sit and rot in cold ground.

What soil temperature does Microgreens Mix need to germinate?

Microgreens Mix needs a minimum soil temperature of 10°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 long does Microgreens Mix take to grow?

Microgreens Mix takes roughly 12 days from sowing to harvest. Seed usually germinates in about 3 days.

Is Microgreens Mix frost hardy?

Yes. Microgreens Mix 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.
