Establishment
4-8 weeksYoung plant develops root system and initial creeping growth; sparse foliage
Water regularly but allow soil to dry between waterings. Protect from hard freezes. Avoid fertilizing; poor soil encourages better growth. Place in full sun.
Vegetative Growth
2-4 monthsPlant spreads horizontally, stems elongate, needle foliage fills in densely
Reduce watering frequency as drought tolerance increases. Prune tips lightly to encourage branching and bushier spread. Maintain excellent drainage.
Flowering
2-3 months (spring through early summer, often extending into fall)Small tubular flowers appear along stems in blue, purple, pink, or white; attracts pollinators
Maintain current watering schedule. Deadhead spent flowers to encourage more blooms, or leave for ornamental appeal and wildlife benefit. Do not fertilize.
Active Growth/Harvest
OngoingPlant continues spreading; foliage remains fragrant and harvestable year-round in warm climates
Harvest leaves regularly for culinary use; this promotes bushier growth. Prune back by 1/3 in spring to maintain shape and vigor. Monitor for winter cold damage in borderline zones.
Winter Dormancy (Cold Climates)
2-4 monthsGrowth slows or halts in zones 8a-8b; foliage may darken or appear stressed
Reduce water further; plant should be nearly dry. Provide frost cloth or mulch protection in zones 8a-8b. Avoid pruning in late fall. Resume normal care in spring.

Harvest Tips
Harvest year-round by pinching or cutting fresh stem tips (top 2-3 inches). Best flavor in morning after dew dries. For storage, harvest longer stems and dry in bunches or on screens in a warm, airy location (1-2 weeks). Leaves retain flavor when dried. Regular harvesting promotes bushier, denser growth.
