Prune the branches after flowering, leaving 2 to 3 leaves. New flower buds will grow in a few days.
Eight things to note when growing potted roses
1. Roses are drought-tolerant and waterlogging-resistant plants. When cultivating soil pots, strictly adhere to the principle of "don't water without drying, water thoroughly". If you water the roses frequently (especially avoid over-watering on rainy days with high humidity and low evaporation), the roots of the roses will be soaked like "pickles" (essentially different from the principle of hydroponics) and die.
2. When cultivating plants indoors, they cannot be placed in a hall with insufficient light for a long time. They must be moved to a sunny place from time to time to supplement the light. Without photosynthesis, plants will stop producing the nutrients necessary for growth, lose the physiological cycle of water and nutrients (light pumping), and develop yellow leaves, rotten leaves, rotten roots, and even death.
3. Any plant only likes light fertilization. Applying thick fertilizer (especially chemical fertilizer) will cause local root rot and death. Depending on the size of the plant and pot, use 20-20% fertilizer every 1-1.5 months. Apply 40 grains of compound fertilizer (or nitrogen fertilizer) evenly under 1 inch of soil around the pot, or pour fully fermented rice water and other light water fertilizer once or twice a month. As long as the leaves are green and the flowers are growing well, there is no need to fertilize.
4. Soil: The soil suitable for rose growth must have three main points: looseness, good ventilation and good drainage. For flower pot planting, use ruby ??soil mixed with leaf mold soil and dried cow dung. The ratio of the mixed soil is as follows: 60% ruby ??soil, 20% moldy leaf soil, and 20% dry cow dung. If you use the market The roses on sale can be cultivated with soil, which is simple and easy. It can also be used directly. In order to further improve the ventilation, drainage and water retention, if it is mixed with 2-30% of ruby ??soil, the soil can be used to achieve the best condition.
5. Care and Pruning: Pruning can promote the germination of new branches. It also needs to be pruned after flowering, usually to the position of the three compound leaves under the flower.
6. Prevention and control of pests and diseases: The place where the flower pots are placed should be sprayed with 15% quicklime water or carbendazim or potassium permanganate aqueous solution frequently for sterilization. The high temperature of the rainy season from July to August is the period of high incidence of leaf spot and powdery mildew. You can spray 0.3~0.5 degree lime sulfur mixture in Baume, once a week, and spray 2~3 times. If beetle larvae damage is found from June to July, the branches should be cut off immediately. Once other leaf-eating pests are discovered, they should be sprayed with 800 times monocrotophos to control them, which can kill eggs and larvae.
7. Plastic pruning: Generally, no pruning is required. Old plants can be pruned to remove dense branches, dry branches, and diseased and insect-infested branches. Roses bloom, pick them as they bloom and fail, and bloom again after picking, otherwise they will only bloom once
8. Flowering period control: Generally, the natural flowering period is better. Spray the flowers during the bud stage to strengthen the stems, bright color and long flowering period.
