How to water poinsettia

Water collection method

If you want to grow poinsettia well at home, you have to have very strict requirements on water and cannot water it whenever you see water. Poinsettia's sensitivity to water is not only reflected in the degree of dryness and wetness, but also in the water quality requirements. The water that can be used includes rainwater, river water, pond water, well water and tap water. But the specific usage is different

When it rains, use pots or buckets to collect rainwater and then water the plants. Do not expose the plants to the rain.

Pond water and river water should be selected with caution and used with caution around factories, residential areas, hospitals, etc., because the water quality in these areas may have hidden dangers and affect the growth of poinsettias.

The temperature of well water is relatively low, especially in summer, when the temperature is quite different from the atmospheric temperature. Before use, expose it to the sun for a while and wait until the water temperature is close to the atmospheric temperature before use. In addition, exposure to the sun can change the disadvantage of hard well water.

Tap water is commonly used for watering flowers, but tap water contains a lot of chlorine, which affects the growth of plants. When using it, you can expose it to the sun for a while before using it, just like well water.

Water according to the soil dryness

Poinsettia requires a lot of water during the entire growing period, so you need to check it more often and water it frequently. If the substrate is too dry, water it more appropriately. Usually you should water the plant when 1/3 of the soil in the pot is dry. Don't water too much when watering, just water flowing out from the bottom of the pot. But avoid watering halfway, that is, the soil in the pot is wet on the top and dry on the bottom, which can easily cause the abnormal phenomenon of roots growing upward.

Watering time

Poinsettia seedlings should be watered in the evening to promote their growth.

During the peak growth season of mature plants, watering is generally done in the morning. In winter, watering can be done around noon. At this time, the water temperature is close to the air temperature and will not irritate the plants. Try to avoid watering when the sun is strong.

Watering precautions

If the plant has not been watered for a long time, the soil in the pot will become too dry and the plant will wilt. Do not water it heavily immediately. The usual practice is to place the flowerpot in a cool place with high humidity and pour a small amount of water on it. As the plant gradually recovers its upright state, increase the amount of watering.

After watering in the hot summer season, do not expose the plants to direct sunlight. If exposed to direct sunlight suddenly, the water in the soil will evaporate faster and the plants will suffer from physiological water shortage. No amount of watering can save them.

When watering, water small pots more and large pots less. Small pots have less soil and correspondingly less water content, so they are prone to water shortage. When watering, adhere to the principle of watering in small amounts and multiple times. After a large pot is watered at one time, it will take a long time to dry, especially if it is a large pot for small seedlings.
