For many girls, how to raise cactus in summer and understand the topic of flowers and plants in the summer, let's follow the editor to see the specific content!
Cactus is a famous lazy plant and is extremely difficult to maintain. Many novice flower lovers who have just learned to grow flowers will use cactus to practice first. There are many varieties, including giant varieties such as Jinhu, mini varieties such as Xingdou and Qiaowan, and varieties that are good at flowering such as Feihuayu and Caicaoqiu.
No matter what kind of cactus, it is very worry-free to maintain. The most important thing about raising cactus is light. It is now June that has just entered summer. Faced with the scorching sun, many flower friends are in trouble. They don't know whether the cactus should be exposed or not? Today we will talk about this issue.
Do cactus want to bask in the sun in summer?
In many people's impressions, cactus grows in deserts with dry climates, where there is abundant sunshine. So when it comes to whether to suntan the cactus in summer, most flower friends respond to it. Although this idea has some truth, it is not entirely correct.
Wild cactus does come from the desert, where the sun is strong. However, almost all of the ornamental cactus varieties in our potted plants are artificially bred varieties. In order to adapt to the poor lighting environment of many families, breeders continue to crossbreed and cultivate, which has improved the shade tolerance of cactus, and is not as resistant to the sun as wild varieties.
How to raise cactus in summer
The ultraviolet rays of the sun during the dog days of summer are particularly intense. If the temperature exceeds 35 degrees, the cactus is exposed to the sun. Although it will not be sunburned, it will easily burn the cactus, causing tan sunburn spots on the cactus. If the sun is more severe, the ball of the cactus will turn dark green, seriously affecting the ornamental value. So unless the cactus in your home is a wild variety, you don't have to worry about getting sunburned. For most horticultural varieties, avoid summer exposure.
Of course, saying that you should not expose the cactus to the sun in summer does not mean that you should not give it light. If there is insufficient light, it will also cause the cactus to grow slowly, bloom less, or even not bloom.
In summer, you must grasp the degree to which the cactus is exposed, not only to absorb enough light, but also not to let it get sunburned. When the summer temperature reaches above 35 degrees, we must start to pay attention to sun protection. The temperature is the highest at noon and the sun's ultraviolet rays are the strongest. As long as we do not expose ourselves to the sun during noon, there is no problem in giving the cactus more sun during the rest of the time.
Key points for summer maintenance When maintaining cactus in summer, in addition to doing a good job in lighting, we must also pay attention to the following three points: Water-controlling cactus is a very drought-tolerant plant and requires very little water all year round. Even in summer, it cannot be watered too frequently. If you water too much, it can easily lead to root rot. In summer, you still need to wait until the soil in the pot is completely dried before watering it. Choose watering time in the morning or evening, not at noon when the weather is hottest.
