Surface sow and firm lightly; requires light to germinate.
Seed To Bloom:
Start in containers 6-8 weeks before last spring frost. Use a sterile seed starting mix and cover lightly with vermiculite to retain humidity. Water from below by placing in a tray. Keep at about 65-75°F.
Direct sow about 2 weeks after last frost, when soil has warmed.
WHEN TO SET OUTSIDE
In springtime, after all danger of frost has passed.
PLACEMENT & CULTIVATION
I can hardly imagine a garden without salvia, for the genus has so many irreplaceable floral gems–easy to grow, trouble-free, many quick to bloom, and growing lustily in gardens and containers. They offer a neverending parade of flowers ( at least until frost) and the entertainment of their attendant hummingbirds. Those pesky deer avoid it, perhaps stayed by the unpleasant aroma of the bruised leaves. Pinch back once plants reach 6" tall to encourage bushiness. Deadhead frequently or cut for bouquets.
1" per week. Tolerates some drought once established, however flowers best with regular water.
Mix in 1" of compost prior to planting.
Diseases & Pests:
Occasionally susceptible to mildew or rust; prevent by planting in a location that has good airflow. If disease appears, treat with an organic fungicide or neem oil once per week until the problem is resolved. If whiteflies appear, spray down the plant daily with a good blast of water until the pests are gone. Prevent slugs by sprinkling crushed eggshells or diatomaceous earth on the soil around the plant.
When to Cut for Bouquets:
When about 1/2 of florets have opened
