What if there are yellow spots on the leaves of Cymbidium?

Yellow spots often appear in the middle part of the leaves of Cymbidium, which is caused by the too dry and wet basin soil, or the application of too thick fertilizer, or the application of unfermented "raw fertilizer". In addition, in hot weather, if the potted magnolia is exposed to hot, unventilated or scorching sun, coupled with germ erosion, yellow spots will appear, first local yellowing of the leaves, and then until the whole leaves are withered yellow.

Prevention and control methods:

It is better for ① to apply fertilizer lightly than thickly, and to master the principle of applying thin fertilizer frequently.

② in high temperature weather, potted Magnolia should be placed in a semi-shady, cool ventilated place, and fertilizer should be suspended.

The ③ basin soil should not be too dry or too wet.

④ immediately cut off the macular leaves to control the spread.
