Master the method of topdressing edible fungi, why the leaves of Cymbidium are scorched, yellowed and shedding.

Yellowing leaves of Cymbidium

In the middle of summer, the leaves of potted Magnolia appear scorched and yellow. The main reasons are:

First, the temperature is high, the sun is fierce, Rain Water is less, the environment is dry and stuffy and not ventilated.

Second, due to the basin soil is too wet, usually too much watering, basin soil drainage is poor, or basin quality is not breathable.

Third, the application of thick fertilizer, raw fertilizer, such as the use of unfermented horse manure. If the salvage method is caused by improper fertilization, it should be turned over immediately to change the soil and replant. If placed in an improper environment, the place should be changed, the basin soil should be dry, not too wet, and the macular part should be cut off and wait for it to grow new leaves. In addition, the bottom of the basin covered with meat bones, easy to grow "white nematodes", will also make the leaves scorched. The salvage method is to change the basin and replant, remove all the horse dung or meat bones, replace the new soil, and then plant it in the basin.
