Now it has entered the rainy season. During the rainy season, the precipitation has obvious convection and strong intensity, and the local rainfall is relatively large. In the rainy season, it is also a test for the various potted plants we raise. How to help them survive the rainy season is also very important. Let the editor of Boqi.com elaborate on the maintenance knowledge of potted plants in the following rainy season.
The key lies in reasonable watering, lighting and ventilation, and pest control. During this period of time, there is a lot of rain, so pay attention to the dryness and wetness of the pot soil when watering. If it is too wet, it is easy to rot the roots. When the temperature reaches 30℃ or higher, the flowers in dormant or semi-dormant state should be watered less. Watering time is better before 10 am or after 4 pm. At high temperatures, sudden torrential rains often occur, followed by sunny weather, which is a "test" for potted plants. If possible, it is best to move the potted flowers to a ventilated place that is sheltered from rain. If it is not easy to move, you can set up the bottom of the pot, remove the water tray, create drainage and ventilation conditions, and try to avoid direct exposure after the rain.
The rainy season is the season for potted flowers. The most common insect pests are red spiders, aphids, scale insects, etc., which can be sprayed with omethoate. Affected by high temperature and rain, flowers and trees are most susceptible to fungus infection, and roses are also prone to blackening. Carbendazim is a general control agent for spot disease.
　　Of course, the rainy season is not necessarily harmful to plants. For example, abundant rain and suitable temperature will promote the growth of new leaves of plants, which is beneficial to the cutting propagation of plants, and the survival rate will be relatively high. In order to make the new plants grow well, measures such as ditching and drainage should be taken in advance to reduce the groundwater level; proper topping and pruning; and timely spraying of fungicides after the rain is dry.
