Why do you want to leave a hole under the potted plant where you grow flowers?

Potted flowers are overwatered, water fills the soil gap, the air in the soil is replaced by water, and the outside air cannot enter at this time, resulting in soil hypoxia, the respiration of roots is hindered, the physiological function is reduced, and the ability of roots to absorb water and fertilizer is blocked. At the same time, due to the lack of oxygen in the soil, the aerobic bacteria with the function of decomposing organic matter in the soil multiply and move, which increases the soil acidity. Due to the large-scale activities of butyric acid bacteria, a series of toxic substances such as hydrogen sulfide and ammonia are produced, which directly poison the root system.

At the same time, due to the excessive accumulation of alcohol and other substances due to the large consumption of soluble sugar in the body by the hypoxic plants, the photosynthesis is greatly reduced, and finally the flowers die of starvation. In the practice of raising flowers, it is common to see cases of "drowning" the roots of the flowers due to excessive watering, causing the roots of the flowers to turn black and rot. Succulent root plants, in particular, such as orchids, require ventilation and drainage.

Therefore, leaving a small hole at the bottom of the pot can be drained and ventilated to avoid the above situation, especially for planting succulent root plants, which not only requires a hole at the bottom, but also a lot of small holes in the middle of the pot.

Due to overwatering, water will fill the soil gaps, and outside air will not be able to enter, resulting in a lack of oxygen in the soil, and the respiration of the roots will be hindered, which will lead to suffocation and death of the roots. The purpose of leaving the hole is to drain excess water and promote the respiration of the root system.

First of all, plants need water and air to grow, if there are no holes under the pot, all the water for watering the flowers can not seep out in the pot, the roots of the flower are soaked in water for a long time, the roots will rot, and another purpose of opening holes at the bottom of the pot is to let the air circulate better.

You can pad a small porcelain piece on the top of the hole, but you must not block it, the hole is to prevent you from watering and watering for more use, once you water too much will flow out of the small hole, if you don't have it, it is easy to rot the roots if you water too much.

It's just for breathability, if there are no small holes, the water can't seep out, and the flower roots will rot.

The small holes left in the flower pot are mainly for water permeability, because potted plants are different from ground planting, after we water, if there are no small holes, then the water will not flow out, and the plant roots will be soaked, so the holes at the bottom of the pot are for water permeability;

In this way, when watering, if you water too much, the water can also flow out from the small holes, without soaking the roots, and it is also conducive to the growth of plant roots. If the potting soil is relatively tight and not easy to permeate the lead, it is also necessary to put small tiles and small stones on the top of the holes, the purpose is to prevent the soil from blocking the holes and not being permeable.

Plants need water and air to grow, and another purpose of opening holes in the bottom of the pot is to allow air to circulate and allow the roots of the plants to breathe fresh air, otherwise the plants may suffocate to death.

Do not plug the hole, in order to ventilate and prevent root rot, and better know whether the water has been watered, and the water will flow out of the hole.

It is supposed to prevent too much water, and sometimes when it rains, if the water is not drained in time, the plants will drown!

It is to let the excess water flow out after watering the flowers.

There is no need to block, the pot should be opened when it is low, so that the water will flow out when watering, otherwise too much water will soak the flower roots.

No need to block. Find something big and put it around the hole and fill it with soil.

Or go to the park and look for the fallen fruit from the pine tree, which is best to fill in the bottom of the pot.

Look at the size of the hole, if there is a tray underneath, then don't block it regardless of size, if there is no tray, the hole is quite large, you can find an iron mesh similar to cover it. Prevent soil from leaking and water leaking.

It needs to be blocked with small stones or tiles to prevent the soil from leaking out, but it cannot be blocked too tightly, and running water is required.

It is best to spread a layer of ceramsite at the bottom, and if there is only one hole at the bottom of the pot, it is best to poke a few more holes out, these holes are to allow the flower to breathe, so that the flower roots will not be suffocated, and reduce the occurrence of rotten roots.

The hole is for drainage, you can live without a hole, but you should pay attention to the frequency and amount of watering, too much water will be at the bottom of the pot, and after a long time, the roots will rot, and the plant will have problems and even die.

Therefore, if you have to do so, try not to use a container that does not have a hole in the bottom to plant flowers.

The main reason is that the root system of water-raised flowers will absorb the oxygen in the water, resulting in insufficient oxygen in the water. Therefore, it is not easy to raise fish in the pot where the flowers are raised in water.

Yes. If there are no holes under the pot, the water will not seep out in the pot, and the roots of the flower will rot if they are soaked in water for a long time. In order to allow the excess water in the pot to seep out in time, a hole was left in the bottom to keep the soil at the right temperature.

In addition, the roots of the flower not only absorb water, but also breathe air. There are holes under the pots, and there are holes in the pots that do not allow water to accumulate, and there are gaps in the soil so that air can come in, and the roots can breathe smoothly. If there are no holes under the pot, the water accumulated in the pot will squeeze all the air out of the soil, and the roots will not be able to breathe the air, and the flower will suffocate and die.

Raising Junzi Orchid does not need a very large pot, the general size of the Junzi Orchid plant leaves are 2 3 is appropriate, not too large, otherwise one is not coordinated with the proportion of the plant, and the other is the excessive use of water after watering, which will lead to the rot of the root system of the plant.

The first thing to be clear is that there must be drainage holes, and the specific reasons are as follows:

1. Ensure that the convection flow is formed on the top and bottom of the pot, so that the roots can fully absorb oxygen;

2. When watering, it can ensure that the moisture content in the upper and lower soil is balanced;

If there are no drain holes, it will lead to the following:

1. When watering, a lot of water has been stored at the bottom, resulting in no oxygen and the roots will ulcerate;

2. Air convection is not possible, and the roots are very perishable;

1.Excess moisture can be drained.

2.Excess acids and alkalis can be expelled by draining excess water. Achieve soil pH balance.

1. Breathable. Plants should not only absorb water and inorganic salts from the soil through their roots, but also promote the growth of the aerial parts of the plant by enhancing the respiration of the roots. This requires ensuring that there is a certain amount of oxygen in the soil.

If the bottom of the pot is closed, then once there is too much watering or more rain, the pot will accumulate water, which will squeeze the air in the soil, resulting in a lack of oxygen in the soil, and the root system of the plant will suffocate and unable to breathe, resulting in rotten roots and even the death of the plant. The first choice for planting plants in pots is because the mud pot has good aeration, which is conducive to the growth of plants, and the purpose of leaving holes at the bottom of the pot is also this, once the water is too watered or attacked by heavy rain, the water will be discharged from the bottom hole, and the space left can be enriched with air. In order to ensure good permeability, the bottom of many pots is not a hole, sometimes there are two, four or five holes, some pots dedicated to breeding orchids, not only have holes at the bottom, but also leave many holes around, because orchids require particularly good permeability.

2. Drainage. Raise flowers in pots, you should water them frequently, if you don't water them, you will be "thirsty" to death, but sometimes you tend to water too much, if there are no holes under the pot, the water will not seep out in the pot, and the roots of the flowers will rot if they are soaked in water for a long time. Therefore, in order to allow the excess water in the pot to seep out in time, a hole was left at the bottom to keep the humidity of the soil suitable, and the flowers could grow "healthily".

Drain out excess water so as not to say too much and cause root rot 、、、 the plant

Soil moisture and air are needed for root development, and more water can flow away from the air to avoid long-term blisters on the roots from mold and death.

To prevent accidental watering during watering, it can be discharged through small holes to avoid root rot.

It is not possible to plug the hole under the flower pot, its function is to drain the water and aerate.

Excess water will pass through this left tithal,

Raising flowers at home. A variety of flower fertilizers are prepared, among which potassium dihydrogen phosphate is the most used for flowering flowers, and its main elements are phosphorus and potassium, which can promote plant differentiation of flower buds.

It must be to buy some animal manure, or buy some special fertilizer or something to release some earthworms.
