The short answer

Plant
Early March to early April
Site
6+ hours of sun, soil pH 6–8
Biggest risk
Honey fungus

In the UK, sages go in the ground early March to early April.

Sages (Salvia officinalis) — perennial.

Timing is the decision that matters most in the UK: there are 4 separate regional sowing windows, ranging from early March in Southern England to early March in Scotland.

Core growing advice on this page is checked against named horticultural and university-extension sources — see References.

When to pick: Common sage can be grown from seed, but plants will take at least a year to grow large enough to reach harvesting size, and it is much quicker and easier to start with bought plants or cuttings (RHS)

Storage

Frequently Asked Questions

When should I sow sages in the UK?

In Southern England, from early March. In Scotland, wait until early March. Treat these as a guide rather than a fixed date — the governing rule is to sow only once frost risk has passed and temperatures are reliably warm enough.

When do I sow sages?

Sow early March to early April.

What soil pH do sages need?

A pH of about 6–8. That span reflects genuine variation between the authorities we cite rather than a single agreed figure — the References section lists each source's exact range.

What problems affect sages?

Our data links 5 diseases and 6 pests to this crop. See the sections above for each one and how to manage it.

Plan next season before the problems start

Most of the advice on this page comes down to timing and spacing — sowing at the right moment, rotating beds, and giving plants enough airflow. The UK Garden Planner lays your plot out month by month so those decisions are already made before the season starts.
