Key Points for Rose Maintenance in Summer
1. Watering. The most important thing in summer is not to lack water. In areas with high temperatures and intense sunlight, the soil should contain more fine particles with a slight stickiness, such as garden soil, to improve water retention. When you find that after watering thoroughly once a day, the leaves and branches wilt the next day, and they become upright again after watering thoroughly the following morning, it indicates that the root system is relatively full, and it's better to change to a larger pot.
2. Fertilizing. Apply a balanced nitrogen-phosphorus-potassium fertilizer diluted 1000 times every ten to fifteen days. In places where it rains frequently, you can sprinkle some granular slow-release fertilizer on the surface of the pot, which will slowly dissolve with the rain, ensuring frequent application of a thin layer of fertilizer.
3. Pests and Diseases. The main pests are red spiders, caterpillars, and various types of green caterpillars. The main diseases are powdery mildew (in certain varieties) and black spot. Mix fungicides and insecticides every ten to fifteen days. Alternate the use of medications for controlling caterpillars or red spiders. After the weather starts alternating between rain and intense sunlight, spray the fungicide to prevent black spot as soon as the leaves are dry after the rain. For green caterpillars, monitor the plants and manually remove any individual caterpillars found. If they appear in multiple places, use pyrethroid insecticides for immediate results. This year, a fungicide called Tetramycin was used, which is suitable for various diseases and has shown good results.
4. Pruning. In the season of vigorous growth, make sure there is enough spacing between plants to enhance ventilation, and properly thin the overlapping branches and leaves inside the plant to ensure that all branches and leaves are exposed to the sun and benefit from good ventilation. After flowering, prune the flowers. For smaller plants, just cut off the flowers, and for larger ones, cut just below two or three leaves under the flower. Pruning is flexible; for longer flowering branches, prune more, and for shorter ones, prune less. If you want the flowers to be as even as possible, try to prune at the same time, and make sure the main branches after pruning are on the same plane. For varieties that bloom in multiple heads, you can cut one flower as it fades. For varieties that do not bloom in multiple heads, remove the petals (leave the receptacle) of the first faded flowers to prevent the petals from rotting on the branches after being soaked by rain and causing diseases. Try to retain as many leaves as possible that can be exposed to the sun to take advantage of vigorous photosynthesis to produce more nutrients and generate more suckers or shoots.
