Geraniums in winter
Everyone loves geraniums: with their bright colors, they embellish gardens and terraces, especially in the summer. When the cold arrives, however, they need special care.
The geranium plant is perennial: it means that it lives many years, if it is in the right environmental conditions. Geranium is also resistant to cold: it is, however, a plant that does not tolerate too cold temperatures, as its ideal climate is mild.
If we are in an area where the winter temperature drops a lot, it is therefore necessary to pay special attention to our geranium plants, which otherwise would not survive. It is not a question of having to perform complicated operations: it is simply necessary to use some caution.
First of all, it is necessary to prune the plant: it is a delicate and important operation, which is used to clean up the geranium and prepare it for winter, during which it will be in a state of vegetative rest. We therefore eliminate leaves and dry branches (in order to make the plant a less easy prey for insects and parasites), and suspend any fertilization operation (which would hinder the vegetative rest of the plant). Instead, administer a fungicide treatment to prevent the plant from being attacked by mycosis during the cold months. Now, the time has come to proceed with the development of the best way to make our colorful plants survive the winter.
When it is very cold
If you live in an area where the winter is very harsh, it is better to keep the geraniums sheltered inside the house: it is enough to keep them in an area away from heat sources (not next to the radiators!) And keep the barely moist earth. Better if near a window, so that plants can enjoy natural light (but a cellar is also fine). In the event that you do not have the possibility to host the plants in the house, you can resort to a small greenhouse: on the market there are different types, even small and suitable to be kept on the terrace or on the balcony. The simplest ones include a plastic structure (suitable for keeping the plants raised from the ground) and a pvc sheet that covers them, as a form of protection. There are also more complicated models, which include glass panels to be mounted on the structure. In the event that there are few plants and there is not much space on the terrace or in the garden, the first solution is certainly sufficient. The structure (whether in glass, plastic or pvc) maintains the heat inside, forming an ideal climate for geranium plants. You can also make your own greenhouse, in a very simple way: you just have to place the geraniums against the wall, and cover them with a fabric cloth specifically for plants (it is available for sale in any shop specializing in gardening items). In this way, conditions similar to those found in a greenhouse will be recreated. If you choose this solution, it is good to keep the plants raised off the ground, even with a simple wooden fruit box. In this way, the earth will be oxygenated.
