Peony is sensitive to water. It is easy to submerge the root, hinder its breathing, and breed bacteria to cause decay. Less water will lead to poor plant growth and yellow and dry leaves. So we must control the amount of water and water when the soil surface is dry. Generally more in summer, less in winter.
1. Water quality requirements: water for peony must be river water, not tap water. Running water contains chlorine, which has a bad effect on its growth. You can air it for a few days first, and then use it after chlorine volatilization.
2. Control the water temperature: peony has good cold resistance, but it is easy to freeze its roots when it is irrigated with water with low temperature. So to control the water temperature, first put the water in the room, wait for its temperature and room temperature close, then pour.
3. Spray water to cool down: peony is suitable for growing in dry environment, but if the temperature is too high, spray water to cool down. Fill the watering can with water and spray it on the leaves. Water should not be sprayed too much, so as not to breed bacteria due to humidity.
4. Treatment of water accumulation: peony is very afraid of being wet. Once the flowerpot has water accumulation, it will easily wither and die. Therefore, it is necessary to discharge the accumulated water in time and loosen the soil properly to accelerate the evaporation of water. If the water stays for a long time, it may cause root rot. It is necessary to take the plant out of the pot and trim the rotten roots. Then soak in carbendazim solution, sterilize and replant.
