1、 Controlled watering

Sun peanuts are strong and grow well, which is not easy to cause rotten roots. If there are signs of rotten roots, it may be because too much water is applied, so it is necessary to stop watering immediately, loosen the soil, promote the outflow of water in the basin soil, and place it in a well ventilated place to promote the drainage of water as soon as possible

2、 Controlled fertilization

It can tolerate barren soil and has little demand for fertilizer. If it is over fertilized, it will also lead to root rot. At ordinary times, the amount of fertilization should be controlled. If it is found that there is too much fertilization, it can be watered and diluted to promote the outflow of excess fertilizer, and do not accumulate in the flowerpot

3、 More sunshine

In addition to controlling water and fertilization, we also need to see more sunlight and put it where the light can shine, so as to promote the evaporation of water as soon as possible and make the growth more vigorous

4、 Replant

If the rotten roots are serious, in addition to strengthening the maintenance, the roots need to be trimmed and replanted. Take the sunflower out of the pot, cut off the rotten roots with sterilized scissors, wash and dry, and apply bactericide. Prepare proper flowerpots and soil, disinfect before use, and then plant sunflowers, paying attention to maintenance
