Why do wolfberry leaves turn yellow?

Causes and treatment methods

The main reasons for the yellowing of wolfberry leaves are lack of water, lack of fertilizer, lack of iron, excessive watering, excessive fertilization, and bad weather. Let's take a look at the specific solutions:

Water yellow

It is caused by too much watering; the characteristics are that the old leaves do not change, and the new leaves begin to turn yellow; at this time, the amount of watering should be controlled.

Phellodendron chinense

It is caused by too little watering; the characteristic manifestation is that the old leaves begin to turn yellow from the bottom to the top. If the water shortage lasts longer, the leaves of the whole plant will turn yellow, and in severe cases the plant will die. At this time, you must water it quickly.

Fat Yellow

It is caused by too much fertilizer; the characteristics are thick and shiny young leaves with uneven leaf surface; at this time, you should control the amount of fertilizer, turn over the shallow soil, and then water.

Hungry Yellow

It is caused by too little fertilizer; the time for fertilization is not allocated reasonably, resulting in a long interval between two fertilizations; the characteristic manifestation is that the tender leaves and newly grown stems begin to turn yellow. If you see this phenomenon, you must fertilize as soon as possible, otherwise it will cause the death of the plant.

Iron deficiency yellow leaves

The soil fertility conditions in the greenhouse vary greatly, and yellowing leaves often occur. The characteristics are that there are more young leaves, very light old leaves, yellow leaf flesh, green veins, and a clear network is formed. At this time, you can use ferrous sulfate aqueous solution to solve the problem. The method is: seven parts of the residue after oil extraction from oil seeds, five parts of ferrous sulfate, and 200 parts of water to make a times solution and water it.

Weather reasons

The weather is the most uncontrollable. If there is continuous rain or scorching sun during the growing season of wolfberry, wolfberry will have to suffer from the bad weather. You have to rely on heaven, earth or luck!
