1, improper watering
Improper watering is one of the main reasons why osmanthus leaves fall. When excessive watering leads to root erosion and defoliation, shovel the soil in time to promote water evaporation and prune the eroded root system. When the leaves of osmanthus fragrans fall off due to too little watering and serious water shortage, it is necessary to replenish water to osmanthus fragrans in time.
2. Improper fertilization
The fallen leaves of osmanthus fragrans may also be caused by improper fertilization. Excessive fertilization will lead to root burning of osmanthus fragrans. At this time, it is necessary to tie up the roots of osmanthus fragrans in time and put on new soil. When the leaves of osmanthus fragrans plants fall off due to too little fertilization, it is necessary to fertilize osmanthus fragrans in time to supplement nutrients.
3. Insufficient lighting
In addition, osmanthus leaves may be caused by insufficient light. If osmanthus fragrans grows in a dark environment for a long time, it will lose its leaves because of insufficient photosynthesis. In this case, it is necessary to move osmanthus fragrans to a place with sufficient light in time for maintenance, so that osmanthus fragrans can resume normal growth.
4. Soil hardening
Soil hardening is also one of the common causes of deciduous osmanthus fragrans. Soil hardening will lead to soil hardening, so fertilizer and water cannot penetrate around the root system of osmanthus fragrans. After a long time, osmanthus will lose its leaves because it doesn't have enough nutrients and water. It is also necessary to change the soil at this time.
