When does the rose turn over?

Rose is a common ornamental plant in the family, and it is also known as the queen of flowers. The natural flowering period can be May-165438+ 10 every year, so many friends will choose to plant a pot of roses at home. But as the roses grow bigger, how should we turn over the pots for them?

Chinese rose

The root system of Chinese rose is developed, and the basin is full of intertwined fibrous roots in one or two years, which affects the growth of plants because of the tight space. In order to keep the plants in a good growth trend and get more and bigger flowers, it is very important to turn over the pots regularly. Generally, the pot is turned once every one to three years, and the best time is from late February to early April before the end of hibernation and the start of sprouting long leaves. Take the roses out of the pot when you turn it over. Cut off part of the old roots and roots around the mud lump with a sharp knife, and the mud lump can be cut more. Choose a new basin one size larger than the original one, cover the hole with tiles, spread a thin layer of gravel, then spread a layer of base fertilizer with a thickness of 2-3 cm, then spread new soil on it, put mud on the new soil, then fill in the new soil around it and tamp it, and pour enough water in the semi-shade. After one week, it will be transferred to normal management.
