How to grow Chinese roses so that potted Chinese roses can safely get through the summer

Whenever midsummer arrives, Chinese roses are inferior to those in spring and autumn in flower color, flower shape, petal count, flower size and growth vigor, which is truly a regrettable problem. The main factor affecting the flowering of Chinese roses is temperature. In spring and autumn, because the temperature difference between day and night and the light intensity are suitable, the branches develop fully and the flower heads develop perfectly, and they can bloom normally. Although Chinese roses like warmth and sunlight, high temperature and strong light are very unfavorable to flower bud differentiation. In hot summer, plants on the ground surface and potted flowers are not only baked by radiant heat, but also exposed to strong direct light. When the temperature reaches 30°C to 35°C, the flower diameter becomes smaller, the number of petals decreases, the color and form fade and change, the flowering period shortens, some leaves dry up, and a large number of blind shoots appear. Especially in hot and humid weather (above 35°C), a large number of lower leaves turn yellow and fall off, showing a semi-dormant state, so they cannot bloom well in midsummer. How to grow Chinese roses so they can safely get through the summer? Below, Huacaole shares with you an introduction to methods for letting potted Chinese roses safely get through the summer. Summer temperatures are hot and the air is dry. Therefore, taking cooling measures becomes the key and focus of solving the problem.

How to grow Chinese roses so that potted Chinese roses can safely get through the summer

1. From mid-June to mid-August, 40%-50% of sunlight should be shaded, and at dry and hot noon, water should be sprayed on the whole plant and the ground around the potted flowers to lower the temperature. Chinese roses placed on balconies can be moved to shaded places, maintaining good ventilation and a clean environment, and preventing strong light exposure.

2. Remove the flower buds growing during this period of about 40-50 days, peel off the new buds one by one, promote strong branches to sprout from the base, concentrate nutrients on the developing branches, prolong the vegetative growth time, and increase the number of strong branches.

3. Scientific pruning. Pruning Chinese roses is an indispensable, meticulous and regular task. Withered flowers, diseased and injured branches, overlapping branches, dead and weak branches, and aged branches should be cut off in time, and leggy branches should be cut short.

4. Timely topdressing. During the summer growth period of about 40 days, they can bloom repeatedly, so base fertilizer alone cannot meet the needs of flowering. Therefore, before new buds sprout after flowering, when the leaves are flattened and the flower buds are swelling, fertilizer should be supplemented in time. Quick-acting liquid fertilizer is best, and applying undecomposed high-concentration organic liquid fertilizer should be avoided.

5. Pay attention to preventing and controlling pests and diseases. In order to reduce sources of pests and diseases, weeds and fallen leaves should be removed in time. If conditions permit, pungent plants such as scallions, garlic or Chinese chives can be planted at the edge of the pot, which can repel and prevent red spiders, aphids, pollen disease and black spot disease. This method is both labor-saving and economical, and is very suitable for home flower growing.

By taking the above measures, potted Chinese roses can safely get through the summer, with lush leaves and abundant flowers, and the flower color will be even more brilliant in golden autumn. There are many varieties of Chinese roses, with nearly ten thousand in the world, and China also has more than a thousand.
