How to Start It
★ Recommended for beginners
Sage handles light frost, so sow it outdoors about 2 weeks before your last frost. Sow 2 to 3 seeds 0.5 cm deep every 30 cm and keep the soil damp: they are slow, sprouting in 10 to 21 days. Keep the strongest seedling at each spot, and you can start picking a few leaves by late summer.
Sage is a woody plant that comes back year after year where winters are not too harsh, and a thick layer of straw or leaves over the roots helps it through cold winters. After 4 to 5 years it gets woody and bare in the middle, so root a few cuttings or layer a branch to replace it.

About 1 days after you plant it
Your sage is coming along! Let the soil dry a little between waterings, since sage does not like wet roots.
About 44 days after you plant it
Your sage is nearly ready to snip! Pick leaves before it flowers for the best flavour.

Growing Tips
- 1Give sage full sun, at least 6 to 8 hours a day.
- 2It needs well-drained soil, so mix in a little compost and some grit or sand, or grow it in a pot with drainage holes.
- 3Water only when the top 2 to 3 cm of soil are dry, since soggy roots kill sage faster than drought.
- 4A thin layer of compost around the base each spring is all the food it needs.
- 5Trim the plant lightly each spring, cutting back by about a third but never into bare old wood, which may not grow back.
- 6Give plants room for air to flow, and water the soil rather than the leaves, to keep powdery mildew (a white dust on the leaves) away.

How to Harvest
- 1In the first year, pick just a few leaves, then harvest freely from the second year on.
- 2Leaves taste best just before the plant flowers, picked in the morning once the dew has dried.
- 3Snip stems 10 to 15 cm long with scissors, and always leave at least two thirds of the plant to keep growing.
- 4Stop cutting about 6 weeks before your first fall frost so the new growth can toughen up before winter.
- 5Hang small bundles upside down in a dry, airy spot for 1 to 2 weeks, then crumble the leaves into a jar.
- 6Use the leaves fresh or dried in stuffing, roasts and butter sauces, or steep a few in hot water for tea.
Step 5
Saving Seeds
How to Save Seeds
Sage usually flowers and makes seed from its second year on. Bees can cross it with other garden sage varieties flowering nearby, so for seed that grows true, let only one variety flower. When the flower spikes turn brown and dry, cut them into a paper bag and shake out the small, round, dark seeds. Let them dry a few more days, then store them labelled somewhere cool, dark and dry, where they keep about 3 years.
