Winter is coming, and many areas across the country have begun to cool down rapidly on a large scale. The editor has put on down jackets. Winter is the most difficult season for plants, and many flower lovers will put flowers and plants on the balcony in pots. As the temperature gradually drops, some flower varieties may not be able to adapt to lower temperatures and will be frozen to death. So from now on, flower lovers should start to prepare for warmth. Just grasp the 5 key points and easily let the flowers and plants on the balcony spend the winter safely!

, trim

After the cooling in winter, flower lovers should move the flowers and plants that are afraid of the cold from the outdoors to the balcony or indoors for maintenance. If pruning is not done, the branches and leaves will block each other from sunlight and affect light, and consume a lot of nutrients. The branches that are too thin and weak have poor resistance to frostbite and are prone to frostbite in winter, which is not conducive to germination in the spring of the following year. So before moving, you need to trim the branches. Cut off all dead branches and leaves, overly dense branches, thin and weak branches, cross branches, and diseased and insect branches.

. Increase light

As the saying goes, "All things grow by the sun." Adequate light can make the plant cells more active and enhance its resistance to low temperatures. Even flowers that like shade should not be placed in dark places. Plants that like light, such as rose , bougainvillea , jasmine, banyan tree , clematis , etc., should be placed as much as possible in places with good lighting and bask in the sun more often. However, be careful not to place the flower pot too close to the air conditioner or heater to prevent the dry air from dehydrating the branches and leaves of the flowers and plants.

3. Control watering

The temperature in winter is very low, and the water evaporates very slowly. It often takes a long time to dry out after watering the soil in the pot, so there is no need to water the flowers and plants frequently. If you water too much and too diligently, a large amount of water will accumulate inside the flower pot, which will easily cause root rot. For general flower varieties, you can use your fingers to test the moisture of the soil before watering in winter. Only when it feels 2 to 3 cm below the soil is dry, watering is needed. If it is moist, there is no need to water it.

The tap water directly connected from the water pipe is relatively low and cannot water flowers and plants directly. If the temperature difference is too large, it will damage the plant root system. You need to place it on the balcony for more than 3 hours to make the water temperature consistent with the ambient temperature before it can be used for watering.

4. Supplement potassium fertilizer

Generally speaking, after the temperature drops in winter, the growth rate of flowers and plants slows down and no fertilizer is needed. But we can apply some potassium fertilizer to help flowers and plants improve their freezing resistance. The potassium content is the most abundant among the young buds, leaves and root tips that are most likely to be frostbitten in plants. Appropriate supplementation of some potassium fertilizer can improve the activity of young buds and roots, so that flowers and plants will not be easily frostbite in winter.

The easiest potassium fertilizer on the market is potassium dihydrogen phosphate. Let’s take potassium dihydrogen phosphate as an example: add potassium dihydrogen phosphate powder to clean water at a ratio of 1:1000, stir well to make a solution. Water the roots of the plant with solution, use once in 1 to 2 weeks, and it will have an antifreeze effect after 2 times.

5, prevent diseases

If the balcony is fully enclosed, because windows are rarely opened in winter and the environment is poorly ventilated, it is easy to induce large-scale reproduction of bacteria and pests, and pests and other diseases and diseases often occur. Be sure to pay attention to ventilation in winter and open the windows to ventilate on sunny noon. Before winter, it is best to clean all the flower pot walls and trays, and cut off all dead branches, rotten leaves and pests, which can greatly reduce the occurrence of pests and diseases.
