What to do with osmanthus falling leaves, what is the reason for osmanthus falling leaves

If it is a potted osmanthus, too much water will lose the leaves, and reducing the water will not; Too much fertilizer will also fall leaves, thin fertilizer is applied frequently, no lack of application, can make osmanthus do not fall leaves;

In addition, low temperature frost damage in winter will also lead to leaf fall, so that the winter warmth and cold protection can make the osmanthus do not fall leaves.

If osmanthus is planted in the ground, brown spot disease causes defoliation, you can spray 500-800 times carbendazim control, if the fertilization is too close or too much to cause fertilizer to fall leaves, the seedlings should be dug up and replanted, properly cut off part of the leaves, and not fertilized, and wait for a year after the tree body recovers and then apply;

In some areas, the soil layer is thin, and the soil compaction is prone to drought due to lack of water, and such plots are also prone to leaf loss, so they should be moved to other places for planting or soil replanting;

In some areas, the sandy nature is heavy, the water retention performance is weak, and it is easy to cause leaf litter, so the surface should be covered with sand after filling the yellow loam around the tree disk.

Osmanthus prefers sunlight and can tolerate shade, its branches and leaves grow luxuriantly and bloom densely under full light, and the branches and leaves grow sparsely and flowers are scarce in the shade. If you are indoors in the north, you should pay special attention to sufficient light to facilitate the growth and formation of flower buds. Osmanthus is good and moist, and it is important to avoid stagnant water, but it also has a certain ability to tolerate drought.

Osmanthus has less strict requirements for soil, except for alkaline soil and low-lying land or soil that is too clay and heavy, and has poor drainage, it can generally grow, but it is most suitable for slightly acidic sandy loam with deep soil, loose and fertile, and good drainage.

1. Improper planting season Osmanthus likes warmth, if transplanted when the temperature is low, the plant is easy to cause a large number of leaves due to lack of water. If the osmanthus has been sprouted and has long leaves, and in dry weather, and is not planted in time, watering, and proper pruning, it will also cause leaf fall.

2. Too arid When the soil is too dry, the plant sheds a large number of leaves in order to adapt to the environment.

3. Too wet and waterlogged Excessive soil moisture affects the normal life activities of plant roots, and is easy to cause a large number of leaf drops, and even root rot.

4. Excessive fertilization will cause leaf loss due to root injury.

1. The ball is buried too deep when planting.

2. The planting soil has poor drainage and poor ventilation.

3. Plant low-lying places or high groundwater levels.

When osmanthus leaves fall due to excessive watering, it is necessary to loosen the soil in time to evaporate water and prune the eroded root system, and if the leaves fall due to too little watering, it needs to be replenished in time. When osmanthus burns its roots and causes defoliation due to excessive fertilization, it is necessary to change the soil and prune the root system in time, because the nutrients are insufficient to fall the leaves, it is necessary to supplement fertilizer in time.

Improper watering is one of the main reasons for osmanthus leaf loss, when excessive watering leads to osmanthus root erosion and leaf fall, it is necessary to shovel the soil in time to promote water evaporation, and at the same time prune the eroded root system. When too little watering leads to a serious lack of water and leaves of osmanthus, it is necessary to replenish water for osmanthus in time.

Osmanthus leaf loss may also be caused by improper fertilization, too much fertilization will lead to the burning of osmanthus roots, at this time it is necessary to repair the root system of osmanthus in time, and replace it with new soil. When too little fertilization leads to the lack of nutrients and leaves of osmanthus plants, it is necessary to fertilize osmanthus in time to supplement nutrients.

In addition, osmanthus defoliation may also be caused by insufficient light, if osmanthus grows in a dark environment for a long time, osmanthus will lose its leaves because it cannot carry out enough photosynthesis. In this case, it is necessary to move the osmanthus to a well-lit place in time for maintenance, so that the osmanthus can return to its normal growth state.

Soil compaction is also one of the common causes of osmanthus leaf fall, soil compaction will lead to soil hardening, fertilizer and water will not be able to penetrate around the root system of osmanthus for a long time, and it will lead to osmanthus because there is not enough nutrients and water to fall leaves, at this time the soil also needs to be replaced.
