Rosemary thrives when watered thoroughly but allowed to dry out between waterings Giving your plant a good soak once the soil feels dry to the touch mimics its natural mediterranean growing conditions For most garden rosemary plants, this means watering deeply about every 1 to 2 weeks, adjusting based on rainfall and high summer heat In containers, rosemary may dry out more quickly Still, let the top inch of soil dry before thoroughly watering. Rosemary is drought tolerant and can go quite some time without being watered when planted in the ground
In fact, often what will kill a rosemary plant growing in the ground is too much water, and rosemary is very sensitive to drainage. Avoid positioning your potted rosemary under a heating or air conditioning vent, which can cause the plant to dry out quickly. As a general rule, water rosemary about once a week in dry conditions, but adjust the frequency based on the plant’s needs By following these precautions and understanding the specific needs of your rosemary plant, you can ensure its healthy growth and longevity. To avoid root rot from overwatering and keep your rosemary plant healthy, water the herb every one to two weeks or if 2 inches of top soil are dry. Rosemary prefers less frequent but deep watering
When determining how often to water, check the top inch of soil If it’s dry, it’s time to water. One of the most effective ways to determine when your rosemary needs watering is by feeling the soil Stick your finger about an inch deep into the soil near the base of the plant If the soil feels dry to the touch, it’s time to water If it’s still moist, wait a bit longer.
Outdoor rosemary needs less supplemental water than potted plants.
