Does summer Chinese roses need shade?
In the lazy summer when even watering seems too much and no one wants to leave the air-conditioned room, a flower friend said that he has planted more than 200 Chinese roses on the rooftop. Looking at the photos, the house is really spectacular and huge. Wealthy people are so lucky. He also said that dozens of them were bought as mother plants from Tianlang. It sounds like a rich person. In such conditions, without a drip irrigation system, it's really hot enough to kill someone in the summer. Many people have put sunshades on the rooftops. They say it's going to be baked by the sun without it! But there are also many people who say it's not necessary, as Chinese roses love sunlight. Full sun is the best! I also see many people say it's hard to keep Chinese roses alive during the summer. I really want to show off and tell them the truth, but there are too many gods in the group, and no one listens to me, a nobody. So I can only let it be.
In fact, it's fine for Chinese roses to be in full sun. As long as your potting soil can ensure sufficient water, there's no problem. So, is it possible that your soil mixture has very poor water retention, the kind that dries out completely by noon after being watered thoroughly in the morning? If so, even if you choose green mountain pots and ceramic pots, which are excellent in breathability, your plants will still be struggling for life, even if they don't die. Don't say using Tianlang's soil and planting in green mountain pots as Tianlang suggests won't be a problem. Don't say that Tianlang's nursery is in full sun, using the same soil and more breathable planting bags, and everything is fine, growing vigorously. Their full sun is based on the condition of having drip irrigation and sufficient water. If your plants are large and the potting soil has poor water retention, drying out by noon, and they are exposed to the scorching sun for an afternoon until you come back from work to water them, if the watering is thorough, there's no problem, but I'm worried you can't water thoroughly! At this point, I have to mention the roots of Chinese roses! Once you understand the roots, you'll get the principle.
Some people may not understand why the roots, which are supposed to absorb water and nutrients, can rot? Shouldn't they be unaffected? In fact, only the root tips are responsible for absorbing water and nutrients. The other crisscrossing roots are used to anchor the plant, preventing it from being uprooted by strong winds! When the white fibrous roots of Chinese roses are vigorous, it means they are growing normally. If you don't see white fibrous roots except during dormancy, you need to pay attention, as there might be a problem. When the soil is too dry, Chinese roses will also enter survival mode, shedding leaves and stopping growth, forcing themselves into dormancy to conserve energy and reduce consumption, waiting for spring. Therefore, it's highly unlikely that a sun-loving plant will be sunburned to death. It will be tortured to death by alternating droughts! So, if you want to plant Chinese roses in a full-sun rooftop without drip irrigation, green mountain pots may not be suitable for you.
Is it necessary to have sunshades? If you want to see as standard summer flowers as possible, they are useful. Sunshades are mainly for cooling down. The higher the temperature, the less standard the flowers of Chinese roses will be, as they are cool-season plants. Sunshades will not prevent Chinese roses from absorbing sunlight in the summer. After all, an hour of summer sunlight might be as strong as two hours in the spring. Why use the word "possibly"? Because I'm not an expert. I have no evidence to prove this is true. I just feel that humans are also cool-season animals, and I like to sunbathe in winter. But forget about summer! An hour can sunburn the skin. Of course, there are people who are tolerant to sun. But I believe most people don't like to sunbathe in the summer! That's all for today. Bye-bye. If anything is wrong, flower friends can just skip it and consider it as nonsense.
Abovementioned is all about whether Chinese roses need shade in the summer. Have green plant lovers understood it?
