After the New Year, it was discovered that the Chinese roses were infested with red spiders.
Today, the editor will introduce the planting content of green plants and flowers found with red spider infestation on Chinese roses after the New Year, and then the editor will introduce to the netizens.
Yesterday, a flower enthusiast sent a message, saying that after returning to their hometown for the New Year, they found that all their Chinese roses had withered after 10 days. What happened?
Many flower enthusiasts may have encountered this situation. After leaving home for a week, the leaves of the Chinese roses turn gray and even completely wither. In fact, this is caused by red spiders. Chinese roses have many diseases and insect pests, especially when grown indoors. The most可怕 thing is the red spider.
Indoor warmth and poor ventilation are the favorite environment for red spiders, which prefer warm, dry, and stuffy environments. When growing Chinese roses indoors, it is important to maintain ventilation and frequently use pesticides to prevent red spider infestations. If you go out for a long trip and leave the Chinese roses "locked" on the balcony, they will definitely be attacked by red spiders.
If the Chinese roses are left with only stems after being devastated by red spiders, they can still be saved, so there's no need to throw them away in a hurry. Especially in winter pruning, Chinese roses grow slowly. If the leaves have fallen off, we can cut them back severely and then use miticides to save them.
Red Spider Solution
First, prune the Chinese rose potted plants according to the winter severe pruning method. Don't hesitate to cut; cutting off most of the branches is more beneficial for the Chinese roses to recover their growth. You can keep only three or four plump and healthy buds close to the potting soil on each thick branch and cut off the other branches.
For the pruning method of Chinese roses in winter, you can refer to the introduction in the book "How to Grow Chinese Roses from Scratch" or refer to my pruning video.
After the New Year, it was discovered that the Chinese roses were infested with red spiders.
To save the Chinese roses infested by red spiders, pruning is just the first step. When pruning, the cut branches should be immediately put into bags, and the fallen leaves in the pot should also be cleaned up and put into bags. These leaves and branches are full of red spiders and should not be randomly placed. They should be cleaned up promptly, burned, or thrown far away.
After pruning, a comprehensive red spider control treatment is needed. Prepare Abamectin or other miticides and dilute them according to the instructions, and it is recommended to prepare more pesticide solution.
Find a basin, place the Chinese rose potted plant in the basin, and then pour the mixed miticide solution from top to bottom, as if watering. Soak the entire Chinese rose, branches, potting soil, and pot, making sure the potting soil is thoroughly soaked because red spiders often hide in the soil, so the potting soil must also be treated for pest control.
To completely eradicate red spiders, not only should the infested Chinese rose potted plants be treated with pesticides, but other potted plants at home, even those not infected with red spiders, should also be treated synchronously.
Use the miticide solution to spray all the plant leaves, both front and back, and the surface of the potting soil, including the ground. After a day, clean the environment to thoroughly kill the red spiders, which can also greatly reduce the probability of the Chinese roses being infested by red spiders in the future.
The personal suggestion of Green Plant Enthusiast Network is that if you are going away for an extended period in winter, you can completely throw the Chinese roses outside. Chinese roses are not afraid of the cold but fear poor ventilation. It is better to leave them on the rooftop, terrace, or balcony than to keep them indoors.
The above introduction about the complete withering of Chinese roses infested with red spiders after the New Year is provided for everyone's learning and understanding!
