The principle of watering potted plants

1. Water quality

Water for watering flowers is preferably slightly sour or neutral. For plants native to tropical and subtropical regions, the ideal water supply is Rain Water. Potable groundwater, lake water and river water can be watered as potted flowers. The content of chlorine in urban tap water is high, and the water temperature is low, so it is not suitable to directly irrigate potted flowers. It is better to store the chlorine in the pool for several days before watering the flowers when the water temperature and air temperature are close. The difference between water temperature and air temperature should not exceed 5 ℃.

2. Water quantity

People with experience in growing flowers all know that watering potted flowers is not a simple thing. To master the amount of water and check the dry and wet of the basin soil, it is necessary to accumulate experience from practice. You can test with your hands and see with your eyes. If the surface of the basin soil is dry and slightly tidal, it should be watered; if the topsoil is still wet, it can not be watered for the time being. The dry and wet of the basin soil can also be judged by the sound of knocking on the basin by hand. the sound is clear that the basin soil is dry and needs watering.

The water retention capacity varies greatly with different types of potted soil. Fine sand has poor water retention and dries quickly, while peat soil has strong water retention and dries slowly.

Large pot plants can be watered once without watering for 1-2 days or more, while small pots should be watered thoroughly every day.

In short, to see the basin soil watering, not too much, not enough, depending on the basin.

3. Common sense of watering

First, newly planted pots or new pots, the first watering should be thoroughly, generally should be irrigated twice, after the first infiltration, and then irrigated again. When potted with dried fine rotten leaves or peat soil, this soil is not easy to water through and sometimes has to be watered many times. Encounter this kind of situation, had better mix soil a little wet first, put 1-2 days again potted.

Second, the leaves of many potted flowers can not accumulate water, otherwise it is easy to cause leaf rot. Such as paulownia, African violets, lotus flowers, etc., the leaves have dense hairs, should not spray water, especially in the evening. The flower buds and tender leaves of some flowers are not resistant to moisture, such as the flower buds of cyclamen and the leaf buds of African chrysanthemum, which are often perishable when wet for too long. Anthracnose often occurs in the leaves of Cymbidium and Jianlan, and the leaves are seriously damaged after infection. when the disease is found, foliar spraying should be stopped. Other flowers have a similar phenomenon.

Third, epiphytic orchids can not be watered or soaked until the new roots are born, but can only spray water to the leaf surface and the surrounding environment every day to maintain a high air humidity.
