Water for flowers, preferably neutral or slightly acidic. Half of the water people use is river water, pond water, rainwater, tap water or well water. In these kinds of water, rainwater is the best, it contains more natural substances, which is the most needed in plants, followed by river water or pond water, which has more nutrients and mild water quality, especially the pond water with a little yellow green color contains more nutrients. The unpolluted ditch water on the roadside is also a good water.
It is best to water flowers with magnetized water, rainwater, river water, or pond water, as long as the water temperature is close to the temperature of the basin soil, it can be used to water flowers at any time; in winter, it is necessary to place the water to be watered in the sun for a period of time, or add some warm water, so that the water temperature is close to the temperature of the basin soil, and then it can be used to water flowers. In addition, when watering flowers with tap water, it's better to put it in a small water tank or bucket first, and then put it in the sun for 2-3 days, so that some harmful impurities in the water can be precipitated, and the substances contained in the water can be oxidized and purified, so that the temperature of the water is close to the temperature of the pot soil, not too cold or too hot.
Some florists often use tea water to water their flowers, thinking that it can add nutrients to flowers and make them grow better. In fact, it is not only not beneficial to flowers, but also harmful to some extent. Because there are a lot of alkaloids in tea, they will affect the absorption of organic nutrients collected by flowers on the soil; moreover, tea covered on the surface of basin soil will affect the infiltration and permeability of the soil; in addition, tea will rot and mildew, attracting pests, which can be said to be harmful and unhelpful.
