When should I sow Sage in the UK?

In the UK, sow Sage from March to May. It is normally started under cover and transplanted. Wait until the soil has reached 10°C at seed depth rather than going by the calendar - sage will sit and rot in cold ground.

What soil temperature does Sage need to germinate?

Sage 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 deep and how far apart should I sow Sage?

For Sage, space plants 60cm apart.

How long does Sage take to grow?

Sage takes roughly 365 days from sowing to harvest. Seed usually germinates in about 14 days.

Is Sage frost hardy?

Yes. Sage 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.
