How to water flowers Proper watering methods for flowers

Diagram of watering flowers and plants

Water is the source of all things and the basis of life. Without water, there is no life. Flowers and plants are undergoing photosynthesis, respiration, and transpiration. Water is inseparable from everything, but the most important part of growing flowers is watering. In fact, everyone can water, but not everyone can master the scientific watering method, because many flower lovers often suffer from excessive watering during the process of growing flowers. Too much water can cause flowers to die, so why do flowers die if they are watered too much? How to water flowers and plants correctly?

1. Causes of Death of Potted Flowers by Overwatering

If potted flowers are watered too much, water fills the gaps in the soil, and the air in the soil is replaced by water. At this time, the outside air cannot Enter, thus causing soil hypoxia, hindering root respiration, reducing physiological functions, and hindering the ability of roots to absorb water and fertilizer.

At the same time, due to the lack of oxygen in the soil, aerobic bacteria with the function of decomposing organic matter in the soil multiply and act in large numbers, increasing soil acidity. Due to the vigorous 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, because the hypoxic plants consume a large amount of soluble sugar in the body and accumulate excessive amounts of alcohol and other substances, the photosynthesis is greatly reduced, and finally the flowers die due to starvation.

In the practice of flower cultivation, it is often seen that due to excessive watering, the roots of the flowers turn black and rot, and the flowers are "drowned". Therefore, when cultivating flowers, pay attention to the appropriate amount of watering.

2. How to water potted flowers correctly

1. Pay attention to water quality

The water quality is clean fresh water without salt and alkali. Generally, rainwater is the best watering method for potted flowers. Tap water must be stored for a certain period of time until the chlorine in the water evaporates before use. Well water contains various impurities and is generally not suitable for use. Rice water and wastewater from goldfish tanks can also be used to water potted flowers. , Laundry water containing soap or soap powder ingredients and dishwashing water with oil stains cannot be used. For flowers such as camellias, azaleas, orchids, and clivias that require acidic soil, you need to pay more attention to the water quality, otherwise the pot soil will become alkaline, resulting in poor plant growth.

2. Pay attention to the water temperature

Do not water when there is a big difference between the soil temperature and the water temperature (or room temperature and water temperature). You can choose the appropriate time in the morning and evening, or adjust the water temperature (usually If cold water is poured into the pot before being stored in the scorching sun, the plant will immediately produce "physiological drought" and the leaves will soon scorch.

3. Pay attention to the amount of watering

People practice potting. The watering experience of "nine more and nine less" is summarized.

1) Water more herbs and less woody plants;

2) Water more flowers that like tides and like droughts. Water less flowers;

3) Water more if the leaves are large and soft, water less if the leaves are small and waxy;

4) Water more during the vigorous growth period and less during the dormant period;< /p>

5) Water the seedlings in smaller pots more, and the seedlings in smaller pots less:

6) Water more on the balcony and less in the courtyard;

8) Water more when it is dry and less when it is cloudy;

9) Water more for pregnant buds and less for flowering. .

The so-called amount refers to comparison under the same conditions. If you encounter drought and dehydration, and the branches and leaves wilt, you should first move to a shaded place, add less water to the pot, spray a small amount of water on the leaves, and wait until the stems and leaves Lift it up and water it thoroughly. If you water it directly and heavily, it will damage the roots and remove leaves. In case of continuous rainy weather, it is best to move the pot to a sheltered place under the porch; if water has accumulated in the pot for a long time and waterlogging occurs, the plant must be removed and placed in a cool and ventilated place to allow rapid ventilation and dispersion of water. Wait for 3-5 days to recover before potting. If it suddenly clears up after a long rain, the woody flowers must be placed in a cool and ventilated place for 1-2 days before seeing sunlight again. If exposed to the sun rashly, the roots' ability to absorb water will become poor during this period. Even though the pot soil is very wet at this time, the branches and leaves will lose water and dry up (called "waterlogging"), and even die. If this phenomenon has occurred: Immediately move the pot to a cool and ventilated place. Cut off some dry branches, stop watering, and allow it to recover slowly.

4. Pay attention to the watering time

Watering time should be carried out when the plants are growing, but avoid the scorching sun. Exposure. Therefore, watering should generally be done after 9-10 a.m. in winter; before 8 a.m. and after 5 p.m. in summer. For plants in direct sunlight, watering should be heavy in the morning, otherwise they will wilt before the afternoon.

5. Master the principles of watering

Most of the problems with potted flowers come from improper watering. No matter what kind of potted flower technique is used to water water in any season, one principle must be mastered: "Water when it is dry, water when it is dry, and water thoroughly when it is dry." Under the condition that the flowers are not damaged by water shortage, the soil usually remains Less water is safer and more reliable than too much water, that is, "it is better to be dry than wet."

Also note: Do not only wet the surface of the pot with "waist water". The top of the pot soil is wet and the bottom is dry. Over time, the plant roots will wilt due to lack of water, and the potted flowers will grow poorly.

3. How to judge whether a potted flower needs watering

1. Use your fingers (or a small stick) to tap the flower pot. If there is a "shell" sound, it means that the pot is very wet. If dry, water can be applied at this time. If the sound is dull, it means there is still moisture in the upper and lower layers of the pot, and there is no need to water immediately.

2. If the soil is gray and loose, it means that the pot soil is dry and can be watered; if the soil is not loose and there is moisture when a small stick is inserted into the soil, it means that the pot is moist and can be watered slowly.

3. Knead the soil with your hands. If the soil becomes flakes or clumps, it means that the pot soil is moist. If it breaks into pieces, it means that the pot soil is dry and needs watering.

While growing flowers, it is inevitable to encounter some doubts. As long as you master the above watering techniques, your flowers and plants will surely grow vigorously and bloom brilliantly.
