Key Points for the Summer Care of Chinese Roses
With high temperatures in summer, many flowers are easily damaged. For Chinese roses, excessive sun exposure can cause the leaves to turn yellow and fall off. So, how to care for Chinese roses in summer? What are the preventive measures?
Care Tips
1. Temperature
Summer temperatures are high, and the suitable growth environment for Chinese roses is between 15℃ and 26℃. In summer, when temperatures can reach over 30℃, it is necessary to provide shade because growth can be hindered when temperatures exceed 30℃.
2. Watering
At this time, if Chinese roses are in bloom, attention should be paid to water management and avoid frequent watering. When the soil in the pot is dry, we should water it each time. Chinese roses prefer acidic conditions, so when watering, some acidic water can be added. There are many acidic waters, such as rainwater, which is easy to obtain. As long as it rains, you can catch it.
3. Light Colors
Chinese roses like sunlight, but the sun in midsummer is particularly strong. Potted Chinese roses should avoid direct sunlight and be exposed to direct sunlight for about 3-5 hours a day. Especially for Chinese roses with buds, the intense midday sun is not suitable for bud growth and can easily cause bud wilt. In addition, we must ensure good air circulation in summer.
4. Fertilization
Chinese roses like fertilization, so fertilization should be done every month, otherwise the growth will not be good. Some acidic fertilizers can be used for absorption. Special fertilizers can also be applied to Chinese roses, which have strong targeting and nutrient content for rose growth. However, Chinese roses are not suitable for large-scale fertilization in summer. Usually, a 500 times diluted organic nutrient solution can be used, and it is recommended to use it once or twice a week.
5. Soil
If you plant flowers with tap water, you need to loosen the soil more. Because tap water can easily cause soil hardening, which is not conducive to root growth. Of course, some soils are better and do not harden easily. Humus soil is a good choice, as it is rich in nutrients, has strong fertility retention, and contains particles that do not harden easily.
6. Pruning
Summer pruning of Chinese roses should be timely and gentle. In high temperatures during spring and summer, Chinese roses have vigorous metabolic activities during their growing period, and pruning should be gentle. Because the supply and demand of materials between the branches and roots of Chinese roses are relatively balanced. If you prune too hard, this balance will be disrupted, weakening the growth of the roses, which could be fatal. Therefore, the correct method for pruning Chinese roses in summer is to cut the third bud below each flower that has withered with a sharp gardening shear in a timely manner.
Precautions
1. Separate the Pot from the Ground
Raise the bottom of the pot with bricks or wood to separate the pot bottom from the ground, reducing the heat transfer from the ground to the pot and preventing root heat stroke. It also enhances the ventilation at the bottom of the pot.
2. Sprinkling Water to Cool Down
In the hot summer evenings, sprinkling water around the pot can help evaporate the heat from the ground. This is especially suitable for asphalt and concrete surfaces.
3. Disease and Pest Control
Summer is a high-incidence period for diseases and pests. If the plant has poor disease resistance and is in a poorly ventilated environment, special attention should be paid to diseases and pests and appropriate medication should be used. Multi菌灵 and potassium permanganate can be easily sprayed on the Chinese rose plants or around them for sterilization and pest control. If powdery mildew and leaf spot diseases occur, you can spray potassium sulfate mixture to control them. If scale insects and aphids are found, you can spray malathion solution for control.
In summary, these are the key points for the summer management of Chinese roses. Friends who have grown Chinese roses can learn more to prevent their roses from being damaged in summer.
