Water thoroughly once and wait until the soil is almost dry before watering a second time.

The watering principle of seeing dry and wet watering means: watering once and then waiting until the soil is almost dry before watering a second time, its role is to prevent overwatering leading to root rot and pests and diseases caused by moisture.

Seeing dry and wet is the watering principle of general family vegetables, which is suitable for most vegetables.

The watering principle of seeing dry and wet refers to watering once and then watering the second time when the soil is white, and watering thoroughly every time until the drainage hole has water discharged. This watering method is mostly used on neutral flowers, watering the permeable root system can better absorb water, so as to promote more vigorous growth. Note that the amount of watering should be controlled and there should be no stagnant water.

1).The specific method of seeing dry and wet is to water thoroughly, and when the pot clods are dry, the soil surface is white, and then watered, after the surface and internal soil water disappears, then water the second time to make the soil moist. This will prevent overwatering and root rot, as well as pests and diseases caused by a humid environment.

Flowers that like humid environments, such as azaleas, gardenias, Milan, camellia and other flowers, can be watered according to the principle of seeing dry and wet.

2).By observing the dryness of the potting soil, and also according to the situation of the flowers themselves, observe the state of the leaves, and find that the leaves are wilted or the color is not green enough, indicating that there is a lack of water, and the potting soil is relatively dry, so it is necessary to water thoroughly.

3).When watering, it is also necessary to water thoroughly according to the depth of the potting soil, and water until the drainage hole has water discharged, and the flowers in the shallow pot are easier to water through; If you water half of the water, it is equivalent to not watering, which is equivalent to not watering, in this case, you can use chopsticks to insert it into the soil to observe whether it is wet and ensure that it is watered thoroughly.

4).When you observe that the soil color becomes lighter, and there is a gap between the soil and the pot, and the sound of the pot is crisp when you flick it with your finger, it is time to water. Don't wait until the plants wilt before watering, as this can easily damage the plants.

5).Observe the potting soil and the plant itself, but also look at other conditions. If the plants are large and the pots are small, they should be watered frequently; If the plant is small and the pot is large, it should be watered thoroughly after watering once, and the watering can be appropriately reduced; Moist-loving flowers need to be watered more, and drought-tolerant ones can be watered less anyway; Flowers with lush foliage evaporate quickly and need to be watered more.

The principle of watering is to water thoroughly once and then wait until the soil is almost dry before watering a second time.

Its role is to prevent overwatering that leads to root rot and pests and diseases caused by moisture. Seeing dry and wet is the watering principle of general family vegetables, which is suitable for most vegetables. When using this principle, buy pots with drainage holes and good air permeability to control the amount of watering.

For some moist flowers such as rhododendron, camellia, smile, gardenia, Milan, etc., it is necessary to water according to the principle of "seeing dry and wet", and watering when the surface of the cultivation medium is white, and watering until it is moist. To make the potting soil not too dry or too wet for a long time, keep it "moist". Adoption"See dry and wet"The method of watering not only meets the water required for the growth of such plants, but also ensures the respiration of the roots.

The oxygen needed for the plants to grow strongly.

See dry and wet, but it is dry and wet.

"Dry" means that the surface layer of the soil (usually 1 2 cm of soil) is slightly whitish after watering for a period of time, and the water is completely evaporated before watering for the second time, and it cannot really wait for the potting soil to be completely dry or even dehydrated before watering.

"Wet" means to water thoroughly when watering until water seeps out from the drainage hole at the bottom of the pot.

It is not possible to water "half water", that is, only a little at a time, and the soil is always moist at the top and dry at the bottom. In a pot of vigorous plants, the root system is mainly concentrated at the bottom of the pot, and watering half of the water is equal to not watering.

Seeing dry and wet is the watering principle of general family vegetables, which is suitable for most vegetables. It is recommended that you buy a flower pot with drainage holes and good air permeability to control the amount of watering.

Home watering can be used "soaking pot method", that is, the pot is immersed in a shallow pot filled with water (the water surface should not exceed the pot), and the water penetrates evenly into the soil through the drainage hole, fully absorbing water and avoiding half of the water.

Watering flowers should be "dry and wet", which is the original meaning, so it is right to water, don't make mistakes again.

Wet and dry is a common term for growing flowers, which means watering once and then waiting until the soil is almost dry to water a second time.

1. See dry. Seeing dry means that after watering once, when the water inside is basically gone, and the surface of the soil layer has turned white, you can water the next time, and you don't need to wait until the potting soil is all dry before giving water. To judge whether it is dry, you can use your fingers to flick the outside of the flower pot, and make a crisp sound to indicate that the inside is dry, if the sound is very dull, it means that there is still moisture inside.

You can also use your fingers to feel the condition of the soil, and if it is dry, you can hold it and give it water. <>

2. See wet. Seeing moisture means that it needs to be watered thoroughly every time you water the flowers, and you can't just water half of the water to prevent the situation that the top is very wet and the bottom is dry. A pot of vigorous plants, generally absorb the roots concentrated at the bottom of the pot, if only half of the water, the water is difficult to concentrate on the roots, equivalent to no watering, so every time wait until the soil layer is dry before watering, until the bottom of the pot can flow water.

How do you see dry and wet?

First, see dry. 1. Plant status: When the plant is short of water, it will look very unenergetic, and the new shoots and leaves will wilt and droop, and the water shortage will be serious and the leaves will be yellow.

2. Look at the color of the potting soil: if the potting soil is in a wet state, the color is dark black, which means that the moisture content in the soil is sufficient. If the potting soil is white in color and dry to the touch, it is dry.

3. The weight of the pot: when the pot soil is dry, the weight is light, you can move the pot up, if the weight is heavier, it means that it is damp, and there is no need to water the water. If you feel that the weight is lighter, it means that the soil is dry.

4. Listen to the sound: Use chopsticks or fingers to gently tap the pot and listen to its sound. If the sound is crisp, it means that the soil is dry and needs to be watered.

Second, see wet. Seeing wetness means watering thoroughly, watering to the bottom of the pot and stopping after the water flows out, avoiding stopping halfway through watering. Many plant roots grow at the bottom of pots, and if you water them halfway, the roots may not absorb any water at all.
