The reason for the yellowing of Finch Plum leaves

First, if left outdoors, the basin soil may be too dry or too wet, especially due to stagnant water after rain and poor drainage.

Second, put it indoors in a sultry, unventilated shade for a long time, or suddenly move to the outside to be exposed to the sun. After deciduous leaves, as long as the branches are not withered, there are still residual leaves. After gradually putting them in an outdoor semi-shady ventilation place and adding fertilizer and water management, leaves will still grow again after autumn.

Of course, there are some other trivial reasons, such as fat and burning leaf yellow, lack of fertilizer leaf thin yellow, alkali soaked leaf yellow, acid deficient leaf yellow, acid multi-leaf yellow, large pot and small leaf yellow, diseases and insect pests lead to yellow leaves, and so on.

But flower friends do not worry about this situation, we have plenty of ways.

Red spider disease is a reddish-brown oval appearance. Red spiders will form a web above the plant leaves to lay eggs and use mouthparts to pierce the branches and leaves to absorb the sap of the branches and leaves, resulting in the destruction of the chlorophyll of the leaves and the gradual yellowing of the leaves. Grayish-yellow spots will also appear on the leaves until the leaves dry and fall off.

Matters needing attention for family flowers and plants in winter

Precautions for family flowers and plants to spend the winter-when winter comes, people need to add clothes, and the plants at home should also be prepared for the winter. The garden department and relevant horticultural experts put forward the following views on the replenishment of plants in winter.

Fertilizer application of flowers and plants depends on varieties

People have to make up in winter, but for winter flowers and plants, "replenishing" is not necessarily a good way. According to reports, the balcony potted plants in dormant and semi-dormant state should stop fertilizing in winter. For exuberant foliage plants, 0.3% urea can be sprayed or poured, or multi-component compound fertilizer particles can be applied on the basin. Flowers and trees that mainly watch flowers and fruits, such as Magnolia, Milan, pomegranate, crape myrtle, jasmine, etc., should continue to apply available phosphorus and potassium fertilizer. After each pruning, thin fertilizer can be applied to hammer elm, sparrow plum, holly, Luohansong, triangular maple, bayberry, melon seed and yellow poplar, etc.

Watering temperature is exquisite.

Plant evaporation is much less in winter than in summer. Therefore, experts suggest that the frequency of watering plants at home can be reduced appropriately after cold weather. In the water temperature, avoid the difference between water temperature and soil temperature, air temperature is too big. The watering time can be carried out before 10:00 and after 16:00. While watering, we should not neglect to loosen the soil for potted plants, and it is best to put a small amount of ferrous sulfate into some ornamental plants. However, it should also be targeted, for example, hanging orchids had better be put indoors during the winter, and should be watered in time when dry, but not more, otherwise the roots will rot away. Although green pineapple is easier to raise, it should be kept moist all the time, and the temperature should not be too low. Aloe likes water, but it's better to wait until the soil is dry before watering.

Plants also need some air.

After the cold weather, some citizens moved the plants originally from the open-air balcony to their homes for the winter. Experts advise members of the public to prune in time when they find dead branches and disease and insect branches. In the first week of moving into the house, it is best to open the window so that the plants can breathe and gradually adapt to the change of temperature, otherwise it is easy to make the leaves of potted flowers yellow and fall off.
