Sowing and propagation of holly
Harvest the mature Holly fruit in autumn, rub off the peel and wash it with clean water. The seeds need to be germinated. They can be treated with wet sand and low-temperature stratification and sown before March of the next spring. The growth is slow in the seedling stage, so attention should be paid to maintenance and management. Holly seeds often germinate every other year if they are not germinated.
Cutting propagation of holly
The cutting of holly can be carried out in four seasons, which is suitable for late spring, early summer and early autumn. Generally, softwood cutting is carried out in the plum rain season. The cuttings are 6 to 8 cm long. Remove the lower leaves, keep 1-2 leaves and cut them short. The cuttings are 1 / 2 deep. It needs sand as the matrix. After cutting, put up a shed for shade and often spray water to keep the soil moist. It can take root in about a month p>
Breeding precautions of holly
Seedlings can be transplanted and planted after 2 or 3 years of cultivation in the nursery. The best choice for transplantation is in spring. Pay attention to be careful when digging seedlings to avoid damaging roots and transplanting with soil. During the initial planting, do a good job of intercropping and weeding, water reasonably and strengthen management. In addition, Holly is vulnerable to Fraxinus and soot disease. Pay attention to timely prevention and control p>
After cutting, Holly needs to build a shed for shade to reduce transpiration and weaken the direct sunlight seedbed. If cutting is carried out in early spring or late autumn, it needs to be covered with film to prevent winter damage. Water the cuttings frequently to keep the soil moist. Topdressing of cuttings can be carried out in combination with watering, or phosphate: potassium hydrogen plus urea can be sprayed on the leaves. Weeding should be done carefully to avoid collision with cuttings.
