Can Chinese rose be transplanted in summer?
The transplanting time of roses is from late autumn defoliation dormancy to early spring germination of the following year. This stage is most suitable for transplanting roses, and it is carried out in cool and humid weather. Of course, if you don't die at this time, it may not be impossible to transplant in summer. If you want to transplant in summer, you'd better choose morning and evening or cloudy day. Matters needing attention in transplanting Chinese rose in summer:
Water the roses once three days before transplanting, so as to excavate and maintain the soil. Transplanted roses must be pruned, leaving only 3 to 4 branches per plant, and the rest should be thinned from the base. The remaining branches should also be re-cut, and the height should be controlled at about 20 cm. If it grows vigorously, the length can be appropriately left, but it cannot exceed 30 cm. Branched leaves should also be cut off 1/2. It should be noted that two problems should be paid attention to when pruning. First of all, the cutting opening must be smooth to minimize tearing. Second, don't leave buds on short roses.
Second, the seedlings should be raised in the early hours of the morning and transplanted with soil as much as possible. If roses are planted in the ground, one person digs with a shovel, and one person holds the soil behind him tightly. The diameter of soil is about 15 cm, and the density of roses can be slightly smaller. The big roots exposed outside the soil ball should be cut off immediately. After grasping the soil ball, it should be put into the non-woven bag in time to prevent it from being broken.
Third, then plant it as soon as possible, and don't delay it for too long. The planting depth is consistent with the original depth. Too shallow will expose the root system when the soil cracks, resulting in water loss of the root system, and too deep will affect the respiration of the root system. Water it once immediately after planting, twice the next night, three times the next morning, and then water it as usual. After planting, 50% carbendazim wettable powder should be sprayed 800 times to control powdery mildew and black spot.

Maintenance of roses after transplantation
1. watering: after watering for three times, you can water according to the weather conditions, water more when it is hot and dry, and postpone watering on cloudy days. In addition, in hot and dry weather, spraying in the morning and evening can effectively replenish water to plants, improve the air humidity in the small environment and help plants take root. Of course, we should also pay attention to timely drainage in rainy days to avoid waterlogging.
2. Shading: In summer, the temperature is high and the light is strong. Shading can effectively reduce the transpiration of plants and protect plants from direct sunlight. Shading can last until the end of August.
3. Pests and diseases: Summer is the most common season for rose pests and diseases. The roots of transplanted seedlings are often damaged, their growth declines, and they are more vulnerable to pests and diseases. The main diseases of rose are black spot and powdery mildew, which can be controlled by spraying 50% carbendazim wettable powder 800 times every 15 days after transplanting, and stopping taking medicine in mid-September.
4. Pruning: Pruning after transplanting is mainly to remove the flower buds at the top of the new branches, and generally no longer short-cut and fine-cut. Although the rose is in a semi-dormant state from July to August, it can gradually form buds after mid-August. At this time, the bud must be removed, because the rose is in a state of slow seedling, and flowering will consume a lot of nutrients, which is not conducive to plant growth.
