Understanding Rosemary’s Watering Needs

Rosemary grows naturally in Mediterranean climates. It characterizes dry summers and mild winters. When determining watering frequency, one must consider factors such as climate, soil type, and planting location to mimic these conditions. On the other hand, it is important to note that overwatering and waterlogging can cause different problems. Therefore, it is quite important to understand the symptoms of both.

General Watering Guidelines for Rosemary

During the growing season (spring to fall), you might need to water twice a week. But in cooler months, you can cut back to once a week or even less. Adapt the frequency to suit the season and keep your rosemary happy and healthy. See Also: Do deer eat mum?
