Common problems of flowers and plants in preventing cold and oversummer

Is the northward balcony the most likely to cause cold damage to plants?

A:

Northward balcony due to the strong northeast monsoon, it is appropriate to have wind shielding facilities, otherwise the plant is the most vulnerable. On particularly cold days, when the temperature is even colder at night, you can put plastic bags or cardboard boxes on the plants to isolate the cold air, but you should take off this "coat" during the day.

Will the plants freeze when the cold snap hits? How to survive the winter.

A:

In order to avoid the occurrence of cold injury, the first thing is to let the plant receive sufficient sunshine. The sunlight in winter is very soft, and under sufficient light, most of the nutrients produced by photosynthesis are stored in the body, which can improve the cold protection ability of the plant. In addition, due to the weak cold resistance of plants during rapid growth, it is not appropriate to apply too much water, as long as the surface of the basin soil is less than 2 to 3 centimeters before watering. At this time, you can also stop fertilizing or apply long-acting fertilizer to make the plant grow slowly and sturdy, so that it is easiest to survive the winter. When a cold spell strikes, the plant can be moved indoors or in a warmer, sheltered place.

Whether you need to shade all the plants in the hot summer.

A:

In case of high temperature in summer, potted plants can be moved to a cool place, or small and medium-sized potted plants can be moved to the shade of large plants. For large potted plants or garden plants that are not easy to move, sunshade nets can be set up. If the plant grows in large quantities from spring to early summer, it may also lead to too much water evaporation due to too many branches and leaves. Therefore, moderate pruning is needed, on the one hand, to adjust the tree shape, on the other hand, it can also reduce the water imbalance. Moderate pruning can also prevent excessive loss of moisture.
