How to deal with the yellowing of spring feather leaves

Water yellow: mainly caused by improper water and fertilizer, too much watering leads to poor soil permeability, which leads to root rot of spring feather plants. in this case, it is necessary to reduce watering and loosen soil to enhance soil air permeability.

Fat yellow: it is mainly caused by excessive amount of fertilizer. The old leaves turn yellow and fall off, but the new ones are thick and unstretched. In this case, top cabbage or radish seeds can be sprinkled on the plant and pulled out after emergence to consume excess nutrients.

Dry yellow: dry yellow or shedding aging of the lower leaves due to long-term non-watering or plant dehydration. In this case, you can appropriately increase the amount of water and spray more water to meet the water needs of plants and keep the environment moist, or properly spray appropriate chemicals to replenish the necessary water for plants.
