What to do if Michelia alba has root rot? Master the correct remedy methods

1. Water appropriately

Its roots are fleshy. If watered too much, the roots will rot; if too dry, they will wither. So even if you water too little, you must not water too much, and each watering should soak through. Generally, spring is its season of budding, so water it once every two or three days to keep the soil moist. In summer it enters its vigorous growth period, and it should be watered once every morning and evening. If there is heavy rain, help it shelter from the rain, and if there is standing water in the pot, pour it out promptly. From autumn onward, gradually reduce the frequency of watering, and decide whether watering is needed based on the condition of the soil in the pot. If the surface of the soil turns white, it needs watering, generally about once a week. After winter, prevent its soil from being too wet. If you find the leaves turning red and the treetops turning brown, it means the roots are not breathing well and there is standing water. At this time, loosen the soil and ventilate.

2. Reduce high-concentration salt fertilizers

If it is harmed by high-concentration salt fertilizers, its leaves will curl, newly grown leaves will dry up, the roots will rot, and it may even wither and die. This is because animal manure is often used to fertilize it, or fertilizers such as potassium chloride are used too much, so too much chloride ion accumulates in the soil, the concentration of the soil solution becomes higher, and the growth of the plant's roots is impaired. When using animal manure, it should first be fully composted and mixed evenly with the soil, and do not use only chemical fertilizers. If the concentration of the soil solution is too high, water more, increasing the amount and frequency of watering.

3. Avoid burning the roots

In May and June or July and August each year, which is its vigorous growth period, apply fertilizer once every fifteen days, and apply a little nitrogen-phosphorus-potassium fertilizer every about twenty days, about 2-6 grams is enough. If fertilizer is accidentally applied directly to the roots of Michelia alba, the soil around the roots will be too rich and burn the roots, so the roots will rot. You should use a shovel to make a few small furrows in the pot, sprinkle the fertilizer in, then cover it with soil, and water some more. The fertilizer will then seep down to the roots with the water. Do not fertilize it in winter. After new buds grow until June, fertilize once every three or four days; from July to September, fertilize once a week.
