24-72 inches (60-180 cm)
Rosemary requires full sun for at least 6-8 hours per day.
Rosemary prefers low to moderate humidity levels.
Rosemary does not require much fertilizer, but can benefit from a balanced fertilizer applied in early spring.
Rosemary should be pruned regularly to maintain its shape and promote bushier growth. Prune in early spring before new growth appears.
Common pests and diseases for rosemary include spider mites, whiteflies, and powdery mildew.
12-24 inches (30-60 cm)
Rosemary prefers well-drained soil and should be watered deeply but infrequently. Allow the soil to dry out slightly between waterings.
Rosemary prefers warm temperatures between 60-80°F (16-27°C), but can tolerate temperatures as low as 30°F (-1°C).
Rosemary can be grown year-round in warm climates, but is typically grown as an annual in colder climates. It can be planted in the spring after the last frost.
Rosemary is relatively easy to grow, but can be challenging for beginners due to its specific light, watering, and pruning requirements.
Rosemary is hardy in USDA zones 7-10.
In ancient Greece, rosemary was believed to improve memory and was often worn by students while studying for exams. Recent studies have shown that the essential oil of rosemary may actually improve cognitive function.
