What about the rotten roots of white orchids?

1. Proper watering

Its roots are fleshy, if they are watered too much, they will rot, and if they are too dry, they will wither, so even if they are not watered too little, they should be watered thoroughly every time. In general, spring is the season for its germination, and it should be watered once in two or three days to keep the soil moist. In summer, it has entered a prosperous period of growth, watering it once every morning and evening, covering it if it is a rainstorm, and dumping it in time if there is stagnant water in the basin. Start from autumn to slowly reduce the number of watering, according to the situation of the soil in the basin to decide whether to water, if the surface of the soil is white, it needs to be watered, usually once a week or so. After winter to prevent its soil is too wet, if found that the leaves are red, the top of the tree turned brown, indicating that the root breathing is not smooth, there is stagnant water, this time to loosen the soil, ventilation.

Second, reduce high concentration salt fertilizers

If it is harmed by high concentrations of salt fertilizer, its leaves will curl, the new leaves will dry out, the roots will rot, and even wither and die. This is because it is often fertilized with animal faeces, or fertilizers such as potassium chloride are used too much, and too much chloride ions accumulate in the soil, the solution concentration of the soil will become higher, and there will be problems with the growth of the roots of the plant. Should be in the use of animal manure, should first fully mature, to mix well with the soil, not just the use of chemical fertilizer. If the solution concentration of the soil is too high, it is necessary to water more and increase the dose and frequency of watering.

Third, avoid burning roots

In May and June or July and August every year, it is the peak period for its growth. It is necessary to fertilize it every 15 days and add a little nitrogen, phosphorus and potassium fertilizer every 20 days or so, about 2-6 grams. If you accidentally put the fertilizer directly on the root of Magnolia, the soil around the root will burn, so the root will rot. You should use a spade to make a few small ditches in the basin, sprinkle fertilizer into it, then cover it with soil and pour some water, and the fertilizer will seep into the root with the water. Don't fatten it in winter. After sprouting, you should fatten it every three or four days in June and once a week from July to September.
