How to Safely Overwinter Geraniums? Latest Tips Shared

Geranium, also known as zonal geranium and fish geranium, has bright red and beautiful flowers and is a common herbaceous plant for home potted plants and parks and plazas. As the temperature gradually turns cooler, how to let geraniums overwinter safely is a period that every friend should consider. Below, let's take a look together at the tips for safely overwintering geraniums.

1. Do a good job of keeping warm

When overwintering geraniums, the first thing to do is to do a good job of keeping the geraniums warm. Geraniums like to grow in an environment that is warm in winter and cool in summer. Keeping the overwintering temperature above 10 degrees in winter allows them to overwinter safely. Therefore, for winter care, it is recommended to move the geraniums indoors to ensure they can grow normally.

2. Sufficient light

Winter temperatures are relatively low, and at this time the plant needs more light to withstand the severe cold, so during winter care it should be placed in a sunny place to receive more sunlight. Moreover, winter sunlight is mild and will not scorch it, so it can be safely given full-day sunlight.

3. Control watering

Geraniums prefer a dry environment, so in winter their demand for moisture is further reduced. Therefore, at this time, the amount of watering must be well controlled, and keeping the soil slightly dry is enough. If the soil is too moist, it is instead not conducive to overwintering. Too much watering may also lead to low-temperature freezing damage or root rot, so watering must be controlled, and when watering, choose midday when the temperature rises.

4. Stop fertilizing

In winter, geraniums enter a dormant period, when their growth basically stops. In addition to reduced demand for water, their demand for nutrients is also greatly reduced. Therefore, in winter, in order to avoid fertilizer damage caused by fertilizing, it is enough to apply a phosphorus-potassium fertilizer once before overwintering. After that, no fertilizing is needed throughout the entire overwintering period, until early spring of the following year, when the plant revives and is fertilized again.

5. A well-ventilated environment

When geraniums are moved indoors for care in winter, in addition to the previous points, what also needs attention is maintaining a well-ventilated environment, so as to ensure they can grow normally. If ventilation is poor, their leaves will turn yellow and fall off, and in severe cases cause the plant to die. Therefore, when caring for them indoors in winter, be sure to keep them away from air conditioners and radiators to avoid wilting of the plant.
