What are the dangers of overwatering to 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 proliferation and activity of aerobic bacteria with the function of decomposing organic matter in the soil are hindered, 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 lack of oxygen, the plants consume a large amount of soluble sugar in the body and accumulate too much alcohol and other substances, resulting in a great decrease in photosynthesis, and finally the flowers die of starvation. In the practice of raising flowers, it is often seen that due to excessive watering, the roots of the flowers turn black and rot"Drowning"examples. Therefore, it is necessary to pay attention to the appropriate amount of watering when cultivating flowers.

When watering too much, the harm to flowers and plants is mainly manifested in root rot, which affects the absorption of water and nutrients after root rot, resulting in leaf water loss, soft and drooping, and yellow leaves of dystrophy, which is serious and easy to cause flower root rot and death.

When the watering is too little, the root system can not absorb enough water to provide the water of the leaves, and it is easy to cause water loss of the leaves when evaporating, especially in the high temperature of summer, it is easy to dehydrate and dry up and die of flowers and plants.

Flowers and plants are currently loved by people, and some people have created flower stands for them in order to be able to raise flowers at home, although flower breeding is not simple, and it is not difficult to say. But for some novices in raising flowers, how to water properly has become a hot topic, so what are the symptoms of excessive watering of flowers? How to remedy overwatering of flowers ?

Let's take a look.

Water molecules fill the voids between the soil particles, and the root system cannot breathe, so the problem of root rot occurs once you water too much. If the plant is not watered, the plant will die. But too much watering can be just as harmful to plants as being dehydrated.

If terrestrial plants are submerged in water for too long (even if only the roots are submerged), they will rot or drown due to lack of oxygen. Watering a plant in the right amount is like getting it to eat a healthy diet. Everything should be done in moderation.

For plants to grow healthily, they should be well-watered, but never overwatered.

Loosening soil ventilation If we accidentally water too much when watering the flowers, then we need to put the flowers in a well-ventilated environment and loosen the soil, which can allow the water to evaporate faster and reduce the impact on the roots of the flowers.

Shading If we water the flowers too much, do not put the flowers in the sun, although the speed of water evaporation in the sun is fast, but under the strong transpiration effect, the roots of the flowers can not absorb enough water well, which will lead to the increase of the burden on the roots, and it is easy to make the flowers wilt.

Root pruning If overwatering causes root rot, then we can't alleviate it by ventilation alone, we need to depot the flowers, then cut off the rotten roots, and then dry the root wounds before repotting.

If you breed flowers in a pot, you can tap the pot to see if it makes a low and muffled sound, whether it is lighter than usual, whether the topsoil is white, and if the soil is hard, you can judge whether the flowers are short of water. If you plant flowers in the open field, you can visually inspect the growth of flowers, whether the new leaves are wilted, whether the old leaves at the base are turned down and drooping, whether they are yellow, whether the plants are dark in color, whether the soil is dry, etc.

For flowers to grow and develop properly, their need for water must be met. However, if the potted flowers are overwatered, the water fills the soil gap, and the air in the soil is replaced by water, resulting in a lack of oxygen in the soil, and the root tissue will have difficulty breathing due to lack of oxygen, and the metabolic function will be reduced, resulting in the obstruction of water absorption and fertilizer absorption, and the flowers will suffocate and die in the long run.

Scientific experiments have shown that if the oxygen content in the soil is less than 10%, it will inhibit the absorption of flower roots, and then affect the physiological function of the whole plant. At the same time, due to the lack of oxygen in the soil, the normal activities of aerobic microorganisms such as ammoniating bacteria and nitrifying bacteria with the function of decomposing organic matter in the soil are hindered, and they cannot effectively decompose the organic matter in the soil, thus affecting the quality of mineral nutrition.

Due to the lack of oxygen in the soil, it is conducive to the proliferation and activity of gas-phobic microorganisms such as butyric acid bacteria, producing a series of toxic substances such as hydrogen sulfide and ammonia, which directly poison the roots and cause root poisoning and death. Many people do not understand the above truth, in the flower raising for fear of insufficient water and overwatering, often easy to lead to flower root rot, the flower "drowning" is not uncommon. Therefore, when raising flowers, it is necessary to pay attention to the timely and appropriate amount of watering in order to raise the flowers well.

It can cause difficulty breathing and eventually death.

1. Cuckoo.

Rhododendron requires the soil to be dry and humid but not wet. Generally, in spring and autumn, rhododendrons planted in the open field can be watered once every 2-3 days, and at least once a day in the hot summer.

Daily watering, do not use alkaline water, watering should also pay attention to the water temperature should not be too cold, especially in the hot summer, with supercold water water, resulting in a sudden decrease in soil temperature, affecting the root system water absorption, interfering with the physiological balance of plants. After planting and soil change, water once to make the root system fully contact with the soil, so as to facilitate the survival and growth of the roots.

Pay attention to watering during the growth period, start from March, gradually increase the amount of watering, especially in summer, do not lack water, often keep the potting soil moist, but do not accumulate water, reduce watering after September, and then water the potting soil after entering the room in winter.

2. Aloe vera. Aloe vera has a strong drought resistance, and aloe vera that leaves the soil can be dried for several months without dying. Aloe vera needs plenty of water during the growing season, but is not waterlogg-tolerant. In summer, when it is hot, it is necessary to drench water to keep the soil moist. However, it should not be too wet, and pay attention to drain stagnant water to avoid root rot.

3. Lingjian lotus.

The arrow lotus likes a warm and humid, sunny and well-ventilated environment, and is resistant to dryness and cold, and is afraid of strong light exposure in summer. It is advisable to loose, fertile, well-drained slightly acidic sandy soil. The water used for watering flowers should be neutral or slightly acidic, and generally rainwater and unpolluted river and lake water can be used.

It is best to leave tap water for 2 days to let the chlorine in the water run away before using it. 3 April is the time to make the arrow lotus bud bud, so you should water more; 5 July is the flowering season of arrow lotus, at this time, the amount of watering should be reduced, and watering once a week can be done.

After flowering, you should pay more attention not to be too dry and wet, and it is better to be slightly dry; Before and after the frost falls in mid-October, it should be dried and watered thoroughly, and it should be dry and wet. November to March of the following year is the dormant season, so it is necessary to water sparingly and keep the soil not too dry.

4. Cactus.

Drought tolerant, proper watering during the growing season, and slightly drier dormancy period. The time of watering is early in the summer, early afternoon in the winter, and morning and evening in spring and autumn. In general, do not pour water from the top, otherwise there will be unsightly spots on the sphere for a long time.

In general, watering must be done sufficiently, for which the soil must be loosened frequently, so that the potting soil can easily and evenly absorb enough water. During the winter dormancy period, watering should be controlled to keep the potting soil not too dry, and the lower the temperature, the more it is necessary to keep the potting soil dry. Adult bulbs are more drought tolerant than small seedlings.

5. Peony. Water once after planting. Peonies should avoid stagnant water, and water them as appropriate during the growing season. In the arid areas of the north, water is generally used before watering, after flowering, and frozen water. In order to facilitate management, the pot can cut off the residual flowers after the flowers bloom and bury them in the ground.

Sex prefers warm, cool, dry, sunny environments. It likes sunlight, and is also resistant to semi-shade, cold, drought, weak alkali, avoid stagnant water, afraid of heat, and afraid of direct sunlight. It is suitable for growing in loose, deep, fertile, high-dry, well-drained neutral sandy loam soil.

Poor growth in acidic or clayey soils.

Remember not to water too much of these 4 kinds of flowers at home, and if you do it right, you can grow more and more prosperous, and learn quickly.

That's enough! There must be holes under the pots, if there are no holes, you must not be able to water more, otherwise the roots will rot. Enlarge the sun to evaporate the water quickly.

There must be a leaky hole under the pot where you plant flowers (unless you are raising aquatic flowers), either drill a hole or change the pot.

The reason for watering flowers: most of the plant body is water, and the water accounts for 75 to 90 of the fresh weight of the plant.

Water quality: Water is divided into hard water and soft water according to the condition of the salt content. Potted flowers are best watered with soft water.

Rainwater, river water, lake water, pond water, etc. are all called soft water, which is generally weakly acidic or neutral, and is suitable for watering flowers; Water temperature: Generally, the optimal temperature for the growth of floral flowers is 20 to 25. The temperature of the water should not differ too much from the air temperature at that time, and the temperature difference between the water temperature and the soil temperature should be kept within 5.

In summer, it is advisable to water at noon, and it is advisable to water in the morning and evening. In winter, it is advisable to water at noon; Watering amount: Generally, potted flowers should master the principle of "seeing wet and dry", and woody flowers and cacti should master the principle of "dry and wet".

In summer, indoor flowers should be watered once every 2 to 3 days, and outdoors should be watered once a day; Watering time: in spring, autumn and winter, around 10 a.m. and after 4 p.m. is the appropriate time to water flowers, the general principle is "spring watering noon, summer watering early and evening, autumn watering the next day, winter diligent look"; Watering method: Most flowers like to be sprayed.
