Several small links to prevent the rotting roots of Cymbidium in spring and the prevention and control of edible fungus diseases

Spring is the season of exuberant growth of Cymbidium, but it is easy to rot due to improper management of water and fertilizer, which is mainly due to the following reasons.

First, the water is overwatered.

No matter it is a small seedling or a large seedling, the water should not be overpoured. If the water is big, the temperature is high, and no matter how bad the ventilation is, the gentleman orchid will surely rot its roots.

Second, it is native Taisheng.

Whether using rotten leaf soil or horse dung soil, the preparation of nutrient soil with peat soil must be fully fermented. If some raw soil is put into the basin, under the condition of high temperature, these raw soil will produce high temperature after fermentation and burn the fleshy root.

Third, the fertilizer has not been fermented.

Give bean cake to the orchid, sesame seeds, fishy water must be fully fermented, if some raw fertilizer is applied to the basin soil, it will also produce high-temperature burning fleshy roots.

Fourth, it is the excessive amount of fertilizer that leads to rotting roots.

In particular, we can not apply too much chemical fertilizer, because the irritation of chemical fertilizer is too great, although it can promote the rapid growth of leaves in a short period of time, excessive fertilization can damage the fleshy roots too much, and it is easy to cause atrophy and rotting roots.

Fifth, the use of poor permeability of porcelain pots, plastic pots to raise magnolia due to poor air permeability, and the roots will be rotten.

Sixth, the temperature is too high.

Especially in the seedling stage, the bottom temperature can be maintained at 22 ℃, but some people put the seedling pots and boxes on the hot Kang or radiator for a long time, resulting in quickly covering the roots of the seedlings.

According to the above situation, if we pay attention to prevention, the phenomenon of rotting roots of Cymbidium can be avoided.

But in case you don't have a town, you don't have to worry about finding the rotten roots, just knock the plant out of the basin, cut off the rotten roots, apply charcoal or soot at the cut, and then change the soil and put on the pot again. If the fleshy roots have all rotted away, it does not matter, you can pinch off all the rotten roots, then wash the roots with clean water, and then put them in coarse sand to promote roots, and cut off part of the leaves.
