1. Natural MetabolismCause: The yellowing and falling leaves of the bayberry tree may be due to normal metabolism, and the bottom leaves naturally turn yellow and fall off. Solution: If it is just minor leaf loss, there is no need to worry about this situation. Just wait for the yellow and old leaves to fall off naturally. 2. Improper fertilizationReason: Bayberry trees need reasonable fertilization to maintain their growth. If they are not fertilized for a long time and lack nutrients, they will grow weak and their leaves will gradually fall off. If too much fertilizer is applied, it will cause problems during growth, inhibit growth, and cause problems such as leaf falling and root rot. Solution: During the growth management stage, it is necessary to apply fertilizer reasonably and appropriately to provide sufficient nutrition for growth. Be sure to pay attention to the dosage and do not use too much. 3. InfectionsReason: The bayberry tree may lose leaves because it is infected with wilt disease. There are many causes of this disease, and weaker trees are more likely to get the disease. Solution: For this situation, prevention is the main approach. Remove dead branches and leaves in time, prune diseased and withered branches and leaves. The pruning wounds must not be exposed to the outside. Use 50 times diluted 40% carbendazim solution to irrigate the roots. |
