How should Qin leaf banyan get leaf spot disease?

Short-term temperature fluctuations and too much water in the dormant period will cause leaf spot disease, and the diseased leaves should be removed in serious cases.

Control methods: timely removal of diseased tissue, centralized burning; rotation, indoor soil can be changed; not suitable for plant spraying; spraying from the early stage of the disease to prevent the spread of the disease. The commonly used agents are 25% carbendazim wettable powder 300 times, 50% carbendazim 1000 times, 70% mancozeb 500 times or 50% carbendan 500 times, and so on. Pay attention to the alternate use of agents to prevent bacteria from developing drug resistance.

What if the banyan leaves are dry and withered?

Once we find that the leaves of fir leaves have fallen, we have to find out the reason. usually, as long as we find the cause, the problem of withered leaves can be easily solved.

1. Soil causes.

Because the banyan is suitable for growing in acidic soil, and most of the water we use to water flowers is tap water, over a long period of time, it will lead to alkalization of the soil of banyan, which will lead to the phenomenon of withering leaves.

Solution: you can choose to use pure water when watering every day. if not, you can pick up a bucket of tap water a few days in advance and put it on the balcony for a few days before watering, so as to avoid soil alkalization.

2. Lack of fertilizer.

In the process of conservation, if there is no timely fertilization or insufficient fertilizer, it will cause the leaves to dry and yellow.

Solution: add the amount of nitrogen fertilizer, but do not apply too much at a time, so as not to burn out the plants. It is necessary to apply a small amount of fertilizer many times, so that it can replenish the fertilizer in time and promote plant growth.

3. Diseases and insect pests.

The main disease and insect pest of fir is leaf spot, and severe leaf spots will lead to withering and yellowing.

Solution: if there are a small number of leaf spots, you can move the banyan pot to a place with sufficient ventilation and light, while avoiding spraying water directly to the leaves. If the leaf spot is serious, the whole leaf should be cut off to avoid affecting and harming other leaves. At the same time, it can not only change the basin and soil, but also prevent and control diseases and insect pests.
