Planting techniques and points for attention of potted sweet-scented osmanthus trees

Potted sweet-scented osmanthus seedlings with small plant shape and compact branches and leaves should be selected before planting, and the seedlings with soil balls that survive by cutting, grafting and striping should be selected to pot. After planting, the seedlings should be watered thoroughly and placed in a ventilated place. During the seedling growth period, thin fertilizer should be applied to facilitate root absorption. Be careful not to plant in alkaline soil, watering thoroughly, but also pay attention to drainage, sweet-scented osmanthus is more hardy, room temperature is 2-4 °is appropriate, do not overwinter at high temperature.

I. planting techniques

Sweet-scented osmanthus potted plants should be selected to plant short, compact branches and leaves, with cutting, grafting, striping propagation survival loess ball seedlings on the pot. Apply enough rotten organic fertilizer when putting on the basin. Water thoroughly after planting and place in a ventilated and sprouting place. After 10-12 days, good ventilation and lighting should be provided. You can keep the basin soil moist at ordinary times. During the growth of seedlings, thin fertilizer should be applied to facilitate root absorption. Timely pruning should be carried out after autumn flowering, cutting off withered branches, weak branches, disease and insect branches to facilitate ventilation and light, so that stout short branches are left evenly on each side branch. During the growing period, the sprouting branches should be often cut off to concentrate nutrients and bloom luxuriantly.

II. Points for attention

I'm afraid of alkaline soil. Osmanthus fragrans prefer slightly acidic soil, and the suitable pH value is 5.5-6.5. If planted on alkaline soil, it can lead to withered leaves and even death of the whole plant.

Second, I'm afraid it won't be watered through. When the lower part is dry, the root system can not get enough water, which leads to the drying and withering of the leaves, and even the shedding of the leaves.

Third, I'm afraid of stagnant water. Stagnant water in the soil is easy to cause rotten roots and fallen leaves, and the root system will rot over a long period of time, resulting in plant death.

Fourth, I am afraid of the high temperature to survive the winter. Sweet-scented osmanthus is relatively hardy, if the room temperature is too high, dormant buds in winter or early spring, empty consumption of nutrients, the plant will be underdeveloped.
