In the maintenance of poinsettia, the watering time needs to be determined according to the season, generally in the morning. In winter, water it at noon to avoid frostbite caused by low water temperature. In summer, you need to water it in the morning or at night, and try to avoid noon, so as not to hurt its root system.
When watering it, it is best to use clean rainwater or river water to irrigate the soil in the basin. If tap water is used, it needs to be exposed to the sun for 2-3 days first, and then it can be used after eliminating chlorine.
It should be watered properly to keep the soil slightly wet, without water. In the growth period, there is a large amount of water demand, so water should be replenished in time. Water the soil thoroughly. Don't stop halfway. If the basin soil is dry, it needs to be watered slowly, not too much at a time.
Water every 1-2 days in spring and autumn. In summer, the temperature is high, and it grows vigorously. It can be watered once in the morning and once in the evening. And it is necessary to spray water on the ground properly according to the weather conditions. In winter, the secondary water for watering can be reduced appropriately, once every 3-4 days.
