Fenghua Rose
Propagation: methods such as cutting, ramification and beading are available. Cuttings can be tender cuttings, hard cuttings and buds. Tender shoots are cut from April to May and September to October. To increase long roots, the incision can be dipped in indole butyric acid. Hardwood cuttings can be carried out until the fallen leaves enter the dormant period and germinate in the spring of the following year. Bud insertion can be carried out when new shoots grow to 3-7 cm in spring.
Water and Fertilizer: When the summer is dry, it is necessary to water enough water. It is necessary to pay attention to the bud period and flowering period to provide enough water. Do not accumulate water during the rainy season. Cultivation can be applied to manure or sprinkled with decomposed organic fertilizer, and then turned into the soil. Fertilize diligently during the growing period, and chase the fertilizer 1-2 times after flowering. High temperature and drought should apply thin fertilizer, fertilize once before winter, and remove weeds.
Pruning: The most important thing for rose flower cultivation is pruning. As a bush-like flowering shrub, plants need to be tall and flowering more, and high shear is required; plants that are shorter and blooming are required to be cut lower. Generally only 3-5 trunks are left per plant. In high-shear main branches, 75-120 cm, containing 15-20 buds; in low-shear main branches, 30-40 cm, containing 6-8 buds.
Fenghua rose overwintering: In the northern area, cold protection is required, and the branches can be cut at a distance of 15 centimeters above the ground; it can also be covered with 3-4 layers of corn stalks, covered with soil to close the gaps, and sealed with frozen water. Spray 3-4 degrees lime sulfur mixture before germination in early spring to clear overwintering bacteria. Strengthen management during the growing season to increase plant vigor and disease resistance.
