Establishment
3-6 monthsYoung transplant with limited foliage and shallow root system; plant appears sparse and tender
Water regularly (2-3 times weekly) until established. Avoid overwatering. Plant in fall or early spring in warm climates. Protect from hard freezes in marginal zones.
Vegetative Growth
6-12 monthsSpreading horizontal growth with increasing needle-like foliage density; plant becomes more compact and bushy
Reduce watering frequency as root system develops. Light pruning encourages bushier form. No fertilizer needed; thrives in poor soil.
Flowering
4-8 weeks per flush; can flower multiple times annuallySmall tubular flowers appear along stems in shades of purple, blue, pink, or white; flowering can occur sporadically year-round in mild climates
Maintain minimal water schedule. Do not fertilize as it reduces flowering. Deadheading is optional but can encourage continued blooms.
Mature Landscape Plant
Indefinite (10+ years lifespan)Fully developed groundcover or cascading shrub with dense, fine-textured foliage and continuous or seasonal flowers
Water only during extended drought (6+ weeks without rain). Prune lightly after flowering or in late winter to maintain shape. Tolerance for heat, wind, and poor soil makes this very low-maintenance.

-
Improve drainage; allow soil to dry between waterings; remove affected plants; prevention is key—do not irrigate established plants
-
Spray with insecticidal soap; encourage natural predators; rarely severe on established plants

Harvest Tips
Harvest fresh leaves anytime during the growing season by pinching off or cutting stem tips. For dried rosemary, cut stems just before flowering for peak essential oil content. Dry in bundles in a warm, airy location out of direct sun. Flowers are also edible and can be harvested and dried. Light, frequent harvesting encourages bushier growth.
