Causes and prevention of yellowing of leaves of Artemisia angustifolia

Money tree is a very popular potted plant, there are many growers in our country, and the demand for planting is relatively high. When it is planted, it often encounters the problem of yellowing of leaves. Due to the reasons of batch planting, it will be difficult for us to find the reasons. The following editor will introduce some common reasons for you, so that you can have a direction judgment.

1. Stagnant water

People will not be very careful in watering when planting in batches, and some farmers will even choose drip irrigation, which will lead to serious uneven water for cash trees. Some cash trees that are closer to the outlet will have stagnant water, and just drain it in time after it is found. When watering every day, try to irrigate one by one to avoid stagnant water.

2. More fertilizer

Fertilization is an important thing for the money tree, but too much fertilizer can also cause it to turn yellow. The reason is that fertilizer accumulates in the roots, resulting in excess nutrition in the roots, too many nutrients transferred to the leaves, the leaves can not be decomposed, and the phenomenon of burning seedlings appears, especially in some old leaves. At this time, to control the amount of fertilizer, first suspend fertilization, let it absorb for a period of time, the obvious fertilizer is taken out immediately.

3. Strong light

Friends who raise money trees generally build greenhouses, and the materials in the greenhouses are mostly transparent, because plants like light in everyone's solid thinking. In fact, this can easily lead to the collapse of the money tree because of the strong light, and finally the transport of nutrients can not keep up with the yellowing of the leaves. Therefore, it is best to build a sunshade and try to let the relatively less heated sun in the morning or afternoon to meet the nutritional needs of the money tree.

4. Soil

Soil is also a very important factor. Plants basically have their own favorite pH, Chimonanthus is a kind of plant that likes weak acidity, generally, the ph value is about 6.5-7 is the most suitable for its growth. And the soil permeability is good, with a certain amount of sand mixing is a good choice. Because of the yellowing caused by the soil, it is best to change the soil in time.

5. Disease

When many diseases of the tree will cause the leaves to turn yellow, just look at the roots of the tree to determine whether it is caused by the disease. If there is serious discoloration in the roots, it is undoubtedly caused by the disease. General brown spot, late blight and other early onset of the disease are from the leaf yellowing began. At this time, the diseased plants should be removed first so as not to infect more plants, and then the location of the disease should be removed, and finally it can be treated by spraying drugs.

When cultivating the money tree, we should be careful and check it carefully every few days, especially the color change of the leaves of each plant. And do not be too dense when cultivating, because the money tree is a kind of plant with low gregariousness, and excessive density is easy to induce some situations.
