Rich trees should pay attention to fertilizing in summer, and their roots and yellow leaves are easy to rot if they are not handled properly.

Rich trees like the growing environment with high temperature, high humidity and good ventilation, and the temperature naturally rises in summer, so watering at the beginning of the period should keep up, but not too much, and ventilation should be strengthened after watering at the same time. Generally, it can be combined with water spraying, which can cool and moisturize and make the environment more suitable for the growth of rich trees. And rich trees will also sprout and grow leaves at the beginning of summer, so nutrients can not be lacking.

However, fertilizing rich trees in summer is risky and requires real-time control of temperature changes. Because when the temperature is too high, the rich tree will go into a dormant or semi-dormant state, thus growing very slowly. if it does not stop fertilizing at this time, it will inevitably cause fertilizer damage and let its rotten roots and yellow leaves. Therefore, rich trees need to pay special attention to summer fertilization, careful fertilization, should stop fertilizer in time, otherwise improper operation will cause rotten roots and yellow leaves.

At the beginning of summer, rich trees usually grow vigorously, constantly sprouting, branching and spreading leaves, so they still consume more nutrients. Therefore, it should be fertilized at this stage, but it is best to apply rotten organic liquid fertilizer or general nutrient solution and keep it once every 15-20 days. In this way, the nutrient needs of the rapid growth of rich trees can be well met.

However, as the summer temperature continues to rise, but the ambient temperature is as high as 35 °C, we should stop fertilizing it in time. Because the plant basically enters a dormant or semi-dormant state at this temperature, the growth becomes very slow and no longer branches and leaves, so the nutrient consumption is very low. Even if we fertilize it, it can not be absorbed quickly, on the contrary, the temperature is higher and the water transpiration is faster, and the fertilizer will burn the roots of the plant because the concentration is too high, thus causing the branches and leaves to turn yellow and fall off.

At this time, it is generally in the middle of summer, and the rich tree is in a state of recuperation and recuperation and becomes very fragile. It is not only easy to cause rotten roots due to too much watering, but also easy to cause rotten roots if you continue to fertilize, so you need to stop fertilizing in time. We can wait until the weather turns cool after autumn to restore fertilization to it, and after absorbing nutrients, the plant may soon return to rapid growth and become more leafy and green.

However, after autumn fertilization, it is recommended to use organic liquid fertilizers such as rice panning water and cake fertilizer water, which have been fermented and rotten, and apply thin fertilizer and water every 10 days and a half months. In this way, after summer dormancy, the rich tree will soon return to exuberant growth after fully absorbing nutrients. Summer is generally only suitable for fertilization in early summer, and the fertilizer should be stopped in time when the plant begins to dormancy in the middle of summer.
