Growing Tips for Salvia in Zone 2b
Zone 2b has a short growing season (~111 days). Start Salvia indoors early and use season-extension techniques like row covers and cold frames.
Start indoors 8-10 weeks before last frost; seeds need 65-70°F soil and light to germinate (surface-sow, do not cover). Transplant after last frost when soil has warmed. Salvia is frost-sensitive — even a light frost kills plants. Pinch spent spikes to encourage continued bloom. Tolerates heat and humidity well once established. In zones 9b-11b can be grown as a short-lived perennial.
