1. Select shoots about 13cm for cutting, and leave 3~4 leaflets at the top;
2. Cut the upper end flat with scissors, and cut the lower end obliquely downward;
3. It is best to use shallow pots for cutting, and the soil can be humus mixed with sediment to keep it moist;
4. After successful cutting, it usually takes about 20 days to take root. At this time, potted plants are needed. Take the rose out of the original pot and shake it gently to stretch the roots; Then prepare a slightly larger pot, and then add the loose humus soil prepared in advance to 2/3; Add roses, continue to add soil until it is slightly full, and water it once after 3 hours.

Matters needing attention in rose cutting maintenance
1, soil
Roses are drought-tolerant and have low requirements for soil. Generally, soft and fertile sandy soil can be fattened by adding some leaves and roots, and the bottom layer is covered with gravel to increase air permeability and drainage.
water
Roses like a slightly wet environment and should not be waterlogged. Water once every 15 days in spring and autumn and once every 10 days in summer. Check the wet and dry conditions of the soil at ordinary times. There is no need to water it when it is slightly wet, and then water it when it is dry.
3. Lighting equipment
Roses like light and warmth, and they are usually placed on Nanyang terrace or south window. If possible, it can be placed outdoors to ensure sufficient light, otherwise the flowers will be few and the branches will be weak. However, in hot summer, shade should be properly used to avoid direct glare.
Step 4 apply fertilizer
Rose likes fertilizer, and liquid nitrogen fertilizer can be applied 1-2 times a month during the growth period, such as rotten skin water and compound fertilizer, to promote the growth of branches and leaves; During the flowering period in April and May, phosphorus and potassium fertilizers can be applied two or three times a month, such as potassium dihydrogen phosphate or decomposed banana oil and fish intestine water, to promote civilization.
prune
Pruning is an important part of the maintenance process. Generally, it should be pruned once before the long buds, so as to keep the trunk long, the lateral branches with 3~5 buds, and all the other dead branches and weak branches should be cut off, and the overall density should be moderate.
