In winter, plants consume less energy, entering a kind of hibernation to protect themselves from lower temperatures and to accumulate enough energy to bloom in spring. The cold weather keeps pests at bay and gives watering schedules a break, but it requires other care to ensure a beautiful garden in spring. From cleaning deciduous plants to pruning shrubs, there are several essential tasks so that, with the arrival of the new season, your plants bloom and grow healthy and beautiful.

Check out the essential tasks for taking care of the garden in winter:
- Fertilize plants before winter
It is advisable to fertilize plants every three months; therefore, in the cold season, the ideal time to fertilize them is before winter, as nutrients give plants the energy to get through the cold season stronger.
- Clean and prepare potted plants
Frost can damage potted plants, so it is important to move pots with plants that are more sensitive to cold winter temperatures. Before bringing plants indoors, clean them and remove any fallen or diseased leaves. If it is not possible to move the pots indoors, make sure they are in a protected area, such as a balcony, so they receive protection from strong winds and cold nights.
- Prune shrubs and plants
Pruning of trees and plants should be done mainly at the end of the winter season. It is important that this task is carried out during this period to ensure that plants are ready for spring, resulting in higher quality fruit and more beautiful flowers.
- Water the garden in moderation
In winter, remember that excessive amounts of water can promote root rot and certain plant diseases due to excess moisture in the soil. To combat this problem, allow the soil to dry out between waterings so that water does not accumulate around the plant roots. The cold also means plants require smaller amounts of water for their metabolic functions, mainly because the plant does not transpire as much as on hot days.

By following these steps before the arrival of the next season, you will have a beautiful garden full of tasty fruits and enchanting flowers. Also find out about caring for indoor plants in winter.
