Why are the leaves of Cattleya turning yellow?

Water yellow

Because of excessive watering, the soil is wet for a long time, the air permeability is relatively poor, and even some fibrous roots become rotten. Many young leaves turned dark yellow and dull, and the new shoots shrank.

Fat Yellow

It usually refers to excessive fertilization, which manifests as the tips of old leaves turning yellow and falling off. Although the new leaves are thicker and look shiny, they are generally bumpy and stiff. If it is a valuable flower, you can sprinkle a layer of Chinese cabbage or radish seeds on it, and then pull them out after a few days of germination to allow them to consume nutrients.

Phellodendron chinense

Due to long-term lack of water or dehydration, although the new leaves have normal color, the lower leaves gradually dry up, turn yellow, and fall off, becoming old.

Alkali yellow

This mainly occurs in some acidic soils in the south, while in the north where the water quality is alkaline, the leaves will gradually fade, turn yellow, and even fall off. The simplest way is to water the plants with fermented rice water or rain water.
