Geraniums can brighten up your windowsill during the winter months, but to ensure they bloom vibrantly in the spring, it’s essential to properly prepare them for the colder season. Geraniums, like many plants, go into dormancy from December to March, requiring specific care to thrive through the winter.
Here’s what you should do for your geraniums in November:
Temperature
Ensure a warm environment for your geraniums: the temperature should not drop below +6°C, with an ideal range between 10°C and 15°C.
Light
Geraniums need a lot of light to stay healthy. In winter, you may want to use phytolamps to provide adequate light, as natural sunlight may be insufficient.
Watering
Water your geraniums less frequently in the winter, about once a week. Geraniums aren’t particularly sensitive to humidity, so this is typically enough.
Appearance Care
Inspect the plant regularly. Trim flower stalks in September or October, and remove any damaged or yellow leaves to encourage healthier growth.
Feeding
Geraniums usually don’t need extra feeding during the winter, but if the plant appears weakened, you can apply fertilizers with low nitrogen content to support its health.
Transplantation
It’s best to transplant geraniums in spring rather than fall. Transplanting in autumn may stress the plant and weaken it.
By following these simple tips, you can help your geraniums preserve their energy over winter, ensuring they will reward you with vibrant blooms in the spring.
