How do you overwinter rosemary?
To successfully overwinter rosemary, it is important to provide it with just the right amount of light, water, and soil.
Light: Rosemary needs at least 6 hours of sunlight per day, which can be provided by a south-facing window or a grow light. If you don’t have access to either, you can move the rosemary to a sheltered area outdoors that gets plenty of morning light.
Water: When overwintering rosemary, it’s important to maintain moderately moist soil while still allowing the soil to dry out somewhat between waterings. You should water the rosemary every 7-10 days, avoiding overwatering, which can lead to root rot.
Soil: Rosemary does best in nutrient-rich soil. To give it all the nutrients it needs, you should add an organic, balanced slow-release fertilizer at least once in the spring and then again in the fall.
To ensure that the rosemary stays healthy and survives the winter, be sure to keep it away from drafty windows and cold drafts, and give it some fresh air by opening the window or door near it occasionally.
Additionally, it’s important to look out for pests and disease and to take appropriate action if you find any. Lastly, if you’re growing rosemary indoors, it’s a good idea to prune the plant back at the start of fall and then again in the spring.
