Growing Sage is easy, since it's one of those herbs that don't ask for much.
Apart from the usual grey type of sage there are purple and yellow varieties on the market. They originated from the Mediterranean area.
Salvia is perennial, but it's a good idea to replace the plant after several years when it's becoming more woody.
Starting: Grow Sage by sowing seeds indoors, plant seedlings or grow from cuttings. Propagate in the warmer months. The seed germination stage is somewhat difficult. Space plants 30 - 40 cm apart.
Soil: Well drained soil.
Climate: Likes dry climates better than wet and cold. Larger plants tolerate frost. It's worth experimenting with how to grow Salvia in cold areas if you have a protected sunny place.
Watering: Do not over water.
Fertilizing: Not much in the way of fertilizing is needed.
Harvesting Sage: Pick as needed and harvest before flowering. Prune back hard at the end of the growing season to promote compact growth.
Containers: Growing Salvia in pots at least 20 cm deep is suitable.
Shady areas: Planting Sage in the shade is not as successful as in full sun, but it can be done.
Pests and Diseases: Root rot can be a result of over watering. Sage repels Cabbage Butterfly and its larvae.
