What to do if Osmanthus fragrans leaves fall off

one. Growth habit

In terms of growth habits, Osmanthus fragrans prefers a warm climate and humid air. It cannot withstand drought. It likes deep, well-drained, slightly acidic sandy soil, and the soil must be fertile. Osmanthus fragrans grows very slowly in poor soil. Its branches and leaves will become sparse, the leaves will be very thin, and the leaf color will turn yellow. It may not bloom or the number of flowers will be significantly reduced. It may even have periodic dry top phenomenon. In more serious cases, it may cause the death of the entire Osmanthus fragrans plant. Osmanthus fragrans likes sunlight, but can also tolerate a certain degree of shade. The seedlings of Osmanthus fragrans need to be shaded and avoid direct exposure to the sun, but the adult Osmanthus fragrans must have sufficient sunlight to ensure its normal growth.

2. Daily maintenance

According to previous observations, if one side of an Osmanthus fragrans is close to the wall or two Osmanthus fragrans overlap each other, the side close to the wall or the intertwined part will quickly become sparse, which will seriously affect the posture and visual effect of the entire crown. Therefore, when planting, you must pay attention to choosing a place with good ventilation and sufficient sunlight. In addition, Osmanthus fragrans cannot be polluted by smoke and dust, otherwise it will not bloom. If there is too much water, the leaves of Osmanthus fragrans will turn yellow and fall off, and even the whole tree may die. Therefore, you must not water it too much, and it is best not to have water accumulation.

three. Disease prevention and control:

In fact, if leaf spot disease occurs, it will also cause the leaves of Osmanthus fragrans to fall off. Its leaf spot disease develops from the edge of the leaves to the tip of the leaves. In the early stages of the disease, small white spots appear on the leaves and then gradually expand. The onset time of the disease is generally from July to November, and it is more likely to occur in an environment with high temperature, high heat and poor ventilation. Therefore, it is important to prevent and treat rot disease as early as possible!
