Seedling
2-3 weeksSmall plants with 2-4 true leaves; delicate and tender
Keep soil consistently moist but not waterlogged. Provide bright light and protect from direct sun if indoors. Avoid damping-off by ensuring good air circulation.
Vegetative
4-8 weeksRapid leaf and stem growth with establishment of woody structure; bushy appearance developing
Water moderately and allow soil to dry slightly between waterings. Begin light pinching to encourage bushiness. Provide full sun and good air circulation.
Flowering
4-12 weeks (varies by species)Terminal flower spikes emerge in shades of purple, blue, pink, red, or white depending on species; plant reaches mature size
Continue regular watering. Deadhead spent flowers to encourage prolonged blooming. Some salvias flower repeatedly if deadheaded consistently.
Mature/Established
1-3+ years (perennial)Woody perennial growth with established root system; reduced watering needs; may produce seed if flowers are not deadheaded
Reduce watering frequency significantly. Prune in early spring to maintain shape and vigor. In zones 4-7, provide winter mulch protection. Thin out old woody growth annually.

Harvest Tips
Harvest leaves in early morning after dew dries but before heat peaks, when volatile oils are highest. For culinary sage, begin harvesting after plant is established (3-4 months). Pinch off top 1-2 inches of stems regularly to maintain bushiness. For dried sage, harvest just before flowering, tie in bundles, and dry in a cool, dark, well-ventilated area for 2-3 weeks. Perennial salvias can be harvested throughout the growing season but avoid cutting more than one-third of the plant at a time.
