Light Requirements Rosemary thrives in full sun. It needs at least 6 to 8 hours of direct sunlight daily. If growing indoors, a south-facing window is ideal, and supplemental grow lights may be necessary during winter months.
Watering and Drainage This plant is drought-tolerant once established but needs consistent watering while young. Allow the top two inches of soil to dry out completely before watering again. Overwatering or poor drainage will quickly lead to root rot.
Soil and Potting Use a well-draining, sandy or gravelly soil mix with a neutral pH. If potting, ensure the container has large drainage holes. Terracotta pots are excellent for rosemary as they allow the soil to breathe.
Temperature and Airflow Rosemary prefers warm temperatures and low humidity. Crucially, it requires excellent air circulation to prevent powdery mildew and other fungal issues. Avoid placing it in humid rooms like bathrooms or crowded clusters of plants.
Pruning and Harvesting Prune regularly to maintain shape and encourage new growth. You can harvest sprigs at any time, but avoid cutting more than one-third of the plant's foliage at once. Pruning the woody stems in early spring helps rejuvenate the plant.
