In general, there are small white spots on the rose, which are basically caused by powdery mildew. At first, it was just a white spot, and then gradually spread to the whole leaf plant. When it is serious, it will even cause the whole leaf to turn yellow and fall off.
1. Cut off the branches with powdery mildew, collect them and burn them directly. Don't let them infect healthy plants again.
2. If it is found that rose has powdery mildew, spray it immediately. Buy at least 2 kinds of powdery mildew special medicine to cross pour the root, about 5 days to pour once, basically half a month can cure
3. For the sake of safety, Hua you who doesn't want to use medicine can mix white vinegar and water into a solution in the proportion of 1:50, spray it on the rose leaves, and be sure to soak all the white powder on the leaves.
A few days ago, a friend sent a picture to Huahua. When Huahua saw the dark brown spots on the leaves, she knew that she had got the spider. In the eyes of flower breeders, Starscream is the most annoying pest in the world!
1. If you find that the orchid has red spider, you must spray it quickly, or the whole plant will suffer. It can be sprayed with golden boughs, pyridaben, avermectin, etc. it can be sprayed once every 3-5 days, and then all red spiders can be eliminated!
2. If you really don't want to use medicine, you can light a mosquito repellent incense and put it next to the orchid pot. Basically, you can light one in 2-3 days, and soon kill the spider.
3. In addition to mosquito repellent incense, you can also use washing powder to mix with water. The proportion is about 1:150. After that, you can pour it into a watering can to spray the plants. You can spray it once every five days, which is also the purpose of preventing and controlling spider.
In general, there are small white spots on the fleshy leaves. In nine out of ten, they are scale insects. In summer, the temperature is high and the weather is hot. As long as the ventilation is poor, the scale insects will come to the door.
1. If you find that there are not many scale insects on the flesh, you can use toothpicks, tweezers, etc. to clean the scale insects directly, or you can use a mosquito repellent incense beside the flowerpot, which can also kill the scale insects.
2. If it is found that there are more scale insects on the fleshy surface, it is necessary to spray them. It can be used as an internal insecticide, that is, no matter the medicine is applied to any part of the succulent, the efficacy can be transmitted to the whole plant, thus killing the scale insects that mainly suck the succulent.
3. If you don't want to spray or use mosquito repellent incense, you can also use the essential balm that you have at home. The scale of 1:500 will be used to mix the essential oil and water, and then spray them on the plants, which can kill the scale insects.
Huahua recently found that there are many small black spots on the flowers and leaves at home. It's only after a close look that we know that it's Xiaohei flying! And this little black fly is so tenacious. He killed a lot of people, and still has it all the time!
1. Once it is found that there is a little black fly in the flowers at home, the fastest way is to use medicine. Huahua thinks that the effect of fat insect, flower protecting spirit, etc. on xiaoheifei is good. After mixing water according to the concentration in the instruction manual, filling the root towards the basin soil, basically only 3-4 times, can eliminate xiaoheifei completely
2. It's not enough to just use medicine to fill the root. You can use the armyworm board at the same time. Put the armyworm board next to the flowerpot. In a moment, you can see many little black flies sticking on it.
3. If there are old people and children at home who don't want to use drugs, they can also make insecticides themselves. Mash the garlic and soak it in water. After about 24 hours, filter out the garlic powder. Mix the garlic water and clear water in the proportion of 1:1, and spray directly on the plant.
There is a pot of gardenias in Huahua's house. When watering in the morning, I found that there are many aphids on the leaves. It's really disgusting to death!
1. The most simple and effective way is to use drugs such as fat insect line, spray plants with water, and kill aphids as soon as possible!
2. Another simple and effective way is to use black light. Aphid has phototaxis, in the house with black light, can attract all aphids, several times down, basically will be able to eliminate the aphids.
3. You can also use pepper or prickly ash, boil it in boiling water until it changes color, take out the impurities, and spray pepper water or prickly ash water on the plant, using the pungent smell to drive away the aphid.
