Before sprouting in spring, the cuttings should be cut in 2-4 months. The cuttings should be cut as soon as possible. It is suitable to select the branches with robust growth and no diseases and insect pests for 1-2 years. Pay attention to avoid selecting the branches with excessive length, big pith and freezing damage. When cutting, the middle and lower parts of the branches should be selected as much as possible. The length of the cuttings is about 30 cm..
We can use the mixture of bryophyte and grass carbon plus river sand, do not add base fertilizer, the substrate needs to be watered before cutting, but not water, the cutting container is a little deeper
Use a sharp blade to cut the end of the insert, then insert it vertically into the medium, only one top bud is exposed, and then spray water once. Cutting distance should not be less than 5 cm in general, if the cutting is too dense, it is easy to cause poor development of seedlings after rooting.
After planting, water the soil frequently to keep the soil moist, and at the same time, pay attention to avoid ponding, otherwise it will lead to rotten roots. From the beginning of May to the end of June is the key period of water management. Although the leaves have been expanded, the cuttings have not taken root, and the lack of water is easy to cause the cuttings to die. When the top leaves turn green, it means that the cuttings have begun to take root.
Before rooting, fertilization should not be applied. After rooting, fertilization can promote plant growth. Fertilizer should be applied in liquid form, once a week, with complete fertilizer of about 3% concentration. Pay attention to spray water timely after fertilization, so as to wash off the residual fertilizer on the leaf surface and avoid damaging the leaves.
During the rooting and seedling raising of blueberry, ventilation and diseased plant removal are two main methods to control the disease.
