1. Growth habits In terms of growth habits, Sijigui likes warm climate and humid air, is not tolerant of drought, and likes acidic sandy soil with deep soil layer and good drainage. The soil must be fertile. Osmanthus fragrans grows very slowly in poor soil, with sparse branches and leaves, thin and yellow leaves, no flowering or obvious reduction of flowering, and even periodic top death, which may even lead to the death of the whole Osmanthus fragrans. Sijigui likes sunshine, but at the same time, it can also bear certain dark environment. For the seedlings of Sijigui, it is necessary to shade the sun and avoid exposure to the sun, but the adult Sijigui must have enough sunshine to ensure its normal growth.

2. Daily maintenance According to previous observations, if one side of cinnamon sticks to the wall or two cinnamon sticks overlap each other, the side against the wall or the staggered part will soon become sparse, which will seriously affect the tree posture and visual effect of the whole crown. Therefore, when planting, we should pay attention to choosing a well-ventilated and sunny place. In addition, Cinnamomum cassia can't be polluted by smoke, otherwise it won't bloom. If there is too much water, the leaves of Cinnamomum cassia will wither and fall off, and even the whole tree will die. Therefore, it must not be watered too much, and it is best not to have water.

3. Disease control: In fact, if leaf blight occurs, it will also cause the leaves of Cinnamomum cassia to fall off, and its leaf blight will develop from the edge of the leaves to the tip of the leaves. At the beginning of the disease, white spots will appear on the leaves, and then gradually expand. The onset time of bacterial blight is usually July-165438+ 10, and it is more likely to occur in high temperature, high fever and poor ventilation. Therefore, we must control Fusarium wilt as soon as possible!
