Why do tree leaves turn yellow?

When the leaves of a healthy and vigorous tree suddenly start turning yellow, it is a cause for concern. The problem of yellow leaves on a tree is called chlorosis. The leaves look green due to the chlorophyll in the leaves. In the presence of which, the tree produces oxygen and glucose with the help of sunlight and carbon dioxide. Find out why the leaves of the tree turn yellow and what to do.

Too little or
too much water - Both are major causes of yellowing of the leaves of a tree. If the soil is wet, there is no need to water the tree. Regularly giving too much water will not only cause the leaves to turn yellow, but also soften the trunk of the tree. If the soil becomes dry and the leaves of the tree droop, then you will know that the tree needs water.

If the roots of the plant grow larger than the root-bound
tub, they cannot grow any further. This is also the reason why the leaves turn yellow. In the case of large plants, it is necessary to prune the roots every 1-2 years. If the roots become entangled, the plant cannot gather the necessary nutrients.

Lack of magnesium
: Sometimes the leaves of the plant turn yellow due to lack of magnesium. In this case, dissolve 1 gram of magnesium sulfate or Epsom salt in 1 liter of water. Spray it on the leaves once in 15 days.   

In the absence of adequate nutrients,
just giving water to the plant is not the last thing. Plants also need food. Give organic fertilizer to the plant once in two months. You can also give cow dung fertilizer or leaf rotted fertilizer. You should also give chemical fertilizer. Egg shells, tea leaves, banana peels can be excellent fertilizers.

If the plant is attacked by insects
or fungi, the leaves may turn yellow. Therefore, apply pesticides to protect the plant from insects or fungi.
