How to distinguish between flowers and leaves when they are watered too much or too little

Generally, there are the following reasons: One is water yellow, that is, too much water causes the soil to accumulate water for a long time, poor air permeability and even some fibrous roots rot. It shows that the young leaves are dark yellow and dull, and the new shoots are shriveled.

The second is fat yellow, that is, fat, which is manifested as the tip of the old leaves turning yellow and falling off, and the new leaves are thick and shiny, but generally uneven and unstretched. If it is a precious flower, you can sprinkle a layer of cabbage or radish seeds, and pull it out after a few days of emergence to consume nutrients. The third is dry yellow, due to long-term lack of watering or dehydration, although the new leaves are normal in color, the lower leaves gradually dry up and fall off and age.

Fourth, alkaline yellow, especially some southern flowers like acidic soil, while the northern water quality is alkaline, and the leaves gradually fade and turn yellow or even fall off. The easiest way to do this is to pour fermented rice washing water or rainwater. The top of the new shoots is atrophied, the young leaves are pale yellow, and the old leaves are also darkened yellow.

The reason is that the water has been wet for a long time, the soil is hypoxic, and some fibrous roots are rotten. Watering should be controlled and fertilization stopped. (Look).

1. Decide when to water according to the plant species.

Different plants have different needs for water and cannot be generalized, for example, Araceae plants such as pothos have a relatively large demand for water, so watering should be diligent, while such as fortune trees, succulents, etc., have less demand for water, so watering should be appropriate, not too much.

2. Decide when to water according to the season.

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

3. Decide when to water according to the permeability of the soil.

Different soils have different air permeability and water permeability, and the corresponding water volatilization rate in the soil is also different, so you must first understand the soil where you raise flowers.

4. Decide when to water according to the size and depth of the pot.

Flower pots have sizes, depths and shallows, some plants use large and deep pots, a watering for several months will not dry, in this case, if the plant is watered every three or five times, it is difficult for the plant to escape the fate of rotten roots. On the contrary, some pots are shallow and small, 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 pot, air humidity, north and south, and so on will affect when to water, but everything is the same, that is, the dry and wet conditions of the soil, according to the dry and wet conditions of the soil combined with the characteristics of the plants to water, it is not wrong, do not simply take time as the basis for watering, unless it is based on your usual experience to judge how often to water.

Much, generally a pot of plants has a support underneath, you water slowly until you see water flowing out of the hole to the plate, less watering, the plants are watered to death.

<>1. The potting soil becomes dry according to the weight. We can check the weight of the potting soil, if we find that the weight is much lighter, it is the loss of water in the potting soil, which is an important signal that needs to be watered. Another option is to gently tap the pot with some hardwood sticks, if the sound is crisp and pleasant, it means that the potting soil needs to be watered.

2. Furthermore, we can judge by the color of the potting soil. If the color of the topsoil is whitish and you can feel obvious dryness when you touch it, then we need to replenish water in time.

3. The second is to observe the growth of the plant itself. If there is a lack of water, the leaves will wilt due to lack of water, and the color will not be as bright and shiny as usual, and if it is in bloom, most of the flowers will wither quickly.

4. There are many general principles for watering flowers, such as plum, plum blossom, hydrangea, dahlias, geraniums and other potted flowers that like to dry and are afraid of waterlogging, so they should be watered according to the principle of dry and watering. When the surface of the potting soil is completely dry, you need to water it, slowly along the edge of the pot until the water can flow out from the bottom. If the water is not good, the tip of the root cannot absorb water, which will affect the growth.

However, watering thoroughly is not the same as watering, watering should also be done in moderation, if watering, the fertile soil nutrients in the potting soil will be lost with water.

5. For rhododendrons, camellias, Milan, Nantian bamboo, hydrangeas, evergreen and other flowers that like moisture and are not resistant to water, they should be watered according to the principle of seeing dry and wet, and watering when the potting soil is white, and watering until it is moist. Don't wait until the potting soil is dry, and don't water too much. To make the potting soil dry and wet, neither long-term drought nor frequent wetting, but dry and wet.

6. Centipede grass, calla lily, monstera, umbrella grass and other potted flowers that like large water should be watered according to the principle of preferring wet rather than dry, and the potting soil should be kept moist and not dehydrated. Flowers such as pine and succulents, for dry and drought-tolerant flowers and trees, should be watered according to the principle of preferring dry to wet, to dry thoroughly before watering, never watered.

1. Leaf changes: to judge whether to water the flowers, you can observe the changes in the leaves, when the flowers are short of water and need to be watered, the leaves will turn yellow, there are signs of dryness, and the reeds will also be shriveled and yellow. There will be changes in both the old leaves and the new leaves, the old leaves will start to turn yellow from the tip of the leaves, and the green color of the new leaves will not be noticeable and will look dull.

2. The flower pot becomes lighter: you can weigh the weight of the flower pot with your hands, and the flower pot is obviously lighter, which is the water in it evaporated, and then the weight becomes lighter. In this case, the plant should be watered in time to provide adequate moisture.

3. Soil changes: You can judge whether to water the flowers through the changes in the soil, the color of the soil surface will become lighter and grayish-white, and the soil will be powdery if you twist the soil by hand. Tap the area around the pot with your finger joints, and the sound will be crisper.

Put your finger in it, and if it's dry, it means it's dry, and it's ready to be watered.

If you water too much, a lot of water will flow out of the bottom of the pot, and over time, the roots will rot, affecting the normal growth of the plant and causing problems with the leaves.

1. If you don't water for a long time, you will lack water in plant tissues. It will wither.

2: Overwatering. The roots of the plant are soaked in water and cannot breathe. Therefore they die and wither.

How you water it depends on what kind of flower you have and what habits you have. Most of them are poured all at once, once a week or so.
