Methods of judging plant water shortage

Tell flower friends that one way to check the dry humidity of soil is to use wooden sticks such as toothpicks or ice cream sticks to detect the dry humidity of soil. As shown in the figure below, it is a dry ice cream stick

The following figure is pulled out of the soil. After pulling it out in a few hours or half a day, you can judge the water content of the soil according to the color of the ice cream stick, and then judge whether it is time to water according to the water needs of different plants

Basis for watering plants

1. When to water depends on the plant variety

Different plants have different demands for water, which cannot be generalized. For example, Araceae plants such as green pineapple have relatively large demands for water, so watering should be diligent, while plants such as fortune trees and succulent plants have less demands for water, so watering should be appropriate and not too much

2. When to water depends on the season

Flower friends all know that it takes a long time to dry clothes in winter. This is because the temperature is low in winter, the water volatilization is slow, and the soil of plants is the same. Therefore, the frequency of watering in winter should be lower, and the frequency in summer can be higher

3. When to water depends on the permeability of the soil

Different soils have different air permeability and water permeability, and the speed of water volatilization in the corresponding soil is also different. Therefore, to raise flowers and water, you should first understand the soil in which you raise flowers

4. According to the size and depth of the flowerpot, decide when to water

Flowerpots can be divided into size and depth. Some plants use large and deep pots, which will not dry for several months at a time. In this case, if the plants are watered every three or five times, it is difficult for the plants to escape the fate of rotten roots. On the contrary, some flowerpots are relatively shallow and small. They are watered in the morning and dried in the afternoon. In this case, they should be watered frequently

Finally, the four factors summarized above are only a part, such as the material of the flowerpot, air humidity, South and North, and so on, which will affect when to water. However, it is inseparable from its origin, that is, the dry and wet condition of the soil. Watering according to the dry and wet condition of the soil and the characteristics of the plants raised can not be wrong. It must not be based solely on time, Unless you decide how often to water according to your usual experience
