What is the best time to water plants in winter?

In winter, the temperature is low, the water evaporation is slow, the water demand of the plant becomes less, if the water is too much, it is easy to cause water accumulation in the potting soil and rot of the roots; If you water too little, the plant will not be able to absorb enough water, and the branches and leaves will dry out easily. When watering in winter, you need to pay attention to the time of watering, the amount of watering, and the interval of watering. Here's how to get started.

1.Watering time.

Watering the flowers in winter is usually done at noon or in the afternoon, when the temperature is at its highest, and the soil and water temperatures are closer to each other, which is conducive to the absorption of water by the roots. Watering should be done in the absence of snow or severe cold, as it may cause frost damage and damage to the root system of the flowers.

2.The amount of watering.

In winter, when the temperature is low and the water evaporates slowly, the plants need less water, so they should be watered less or no at all. When watering, wait until the potting soil is dry and whitish before watering, and be sure to water thoroughly at one time. Watering needs to control the amount of watering, too much watering can easily lead to water accumulation in the potting soil and rot of the roots.

3.Watering intervals.

In winter, most of the plants enter the dormant period, slow growth or stop growing, the root system needs less water, when watering, you need to pay attention to the frequency and interval of watering, generally twenty days to a month watering, if the indoor temperature is high, you can also spray water mist on the leaves of the plant to increase air humidity.

Avoid drying out the leaves.

1. If the garden tree is a mature tree, it is okay to water it at any time. If it is a seedling stage, try to water it at night to avoid excessive transpiration.

Second, the watering of garden trees is best to water thoroughly at one time. There was human negligence in checking whether the water was thoroughly watered. To test whether the water is watered through, it is generally pierced straight down with a steel bar or a stick against the soil ball, and if it can be pierced, it is watered through, otherwise it is not transparent.

In practice, the water only penetrates more than half of the side or the upper half of the surface, which is easy to ignore when inspecting, thinking that the water has been watered.

3. In summer, the high temperature generally does not water the trees at noon, and watering in the morning or evening is the most appropriate. It is best to water small seedlings after pruning.

Fourth, beware of overwatering, when the leaves of the plant are soft, you should immediately think of the lack of water. Before watering, carefully check that the soil is very dry. In fact, overwatered plants initially exhibit symptoms similar to those that occur when the plant is deprived of water:

The plant is weakened, and the tissues that absorb too much water lack rigidity. After a few days, brown spots appear on the leaf margins or leaves**, and they gradually enlarge, darken and die. At this stage, the plant has been attacked by a fungus that causes root rot and must be stopped immediately to keep the plant dry.

Flowers in the winter is best every 10 20 days of time to water, if you can not control the number of watering can be in accordance with the dry and wet method of watering, watering time is best to choose a mild noon, along the edge of the pot watering until completely wet, the temperature difference between the water temperature and room temperature can be about 5.

How to water flowers in winter.

1. Watering time.

How to water flowers in winter also need to control the time of watering, according to the growth habits of each flower, usually can be watered in 10 20 days, watering as much as possible at noon, at this time the highest temperature of the plant at this time to absorb more water, can promote the growth of flowers.

2. Watering method.

When watering the flowers, it is necessary to carry out along the edge of the pot, to avoid washing away the soil in the middle, the water will gradually spread to the root position, and it can also ensure that the soil is in a state of total wetness, and the evaporation of water in winter is relatively slow, so the amount of water at a time should not be too much, so as to avoid too much water accumulation in the pot.

3. Watering principle.

The water temperature when watering should be close to the indoor temperature, the temperature difference of about 5 can be maintained, if the number of watering can not be controlled, you can water according to the method of seeing dry and wet, which can greatly avoid water accumulation in the pot, if the indoor temperature is about 20, you need to resume the number of daily watering.

4. Kind of watering.

There will be certain differences in the watering of different types of flowers, herbaceous plants in the daily breeding of the demand for water is relatively large, even in winter also need to keep the soil moist, if the woody plants can be appropriately reduced watering times, just in accordance with the principle of dry watering can be watered.

I think it's best in the evening, because the water can be kept warm at a constant temperature and is not easy to evaporate.

Due to the low temperature in winter, the water for watering flowers should be stored or dried through utensils, and it is important not to water the flowers directly with tap water to prevent the temperature difference from being too large and damaging the root system. Because the temperature continues to drop in winter, the metabolism of flowers is slow, or enters a dormant state, generally potted flowers should strictly control fertilizer and water. If the potting soil is not too dry, do not water, especially shade-tolerant flowers, and avoid root rot and leaf loss caused by excessive watering.

Generally, the watering time should be around noon. For some evergreen flowers that like shade and dampness, such as bamboo, monstera, spring feathers, arrowroot artichoke, camellia, evergreens, etc., the leaves should be sprayed with water close to room temperature to clean and remove dust to facilitate photosynthesis.

Clause.

First, the opening, winter irrigation.

Loosen the soil in time to promote the growth of the root system of overwintering trees. Strengthen the cold-resistant work of winter plants, and reasonably arrange personnel and vehicles to regularly irrigate and water green spaces and lawns to prevent freezing and increase moisture. Trees, especially newly planted trees, should be irrigated with antifreeze water.

After irrigation, combined with frozen water, a mound of soil is built at the roots of the tree.

Clause. 2. Fertilization.

In late autumn and early winter, according to the age of the tree and the length of planting time, some organic fertilizer and chemical fertilizer should be applied appropriately to promote the growth of new roots, enhance the tree potential, and lay a good foundation for the growth and development of the next year.

Clause. 3. Whitewashing.

Plants with poor cold tolerance should be painted dry and white, brushing white is the top priority of winter tree maintenance, which can not only enhance the anti-freezing ability of trees, but also prevent the breeding of pests and diseases, kill aphids, red spiders, scale insects and other overwintering pests, and effectively protect trees.

Clause. Fourth, plastic pruning.

At this time, according to the different landscape characteristics of the tree, the correct shaping and pruning should be carried out, the dead branches, weak branches, diseased and insect branches should be cut together, and the overgrown branches should be appropriately retracted, so as to improve the ventilation and light transmission conditions inside the canopy, cultivate the ideal tree shape, and disinfect the larger wounds with drugs, and apply wound smears to protect them. It is necessary to clean up the grass layer and the ground, clean up the green space and the surrounding litter, garbage, etc., create a clean and tidy garden, ensure that there is no fire hazard, strengthen the inspection of green space, and strictly prevent the occurrence of fire.

Clause. 5. Set up wind barriers.

Wind barriers are installed for newly planted seedlings, newly transplanted trees, and valuable trees that are weak in cold tolerance. The windproof effect of the wind barrier is remarkable, which can make the near-ground airflow in front of the wind barrier relatively stable, increase the local temperature and temperature, and ensure the safe wintering of flowers and trees. Trees in need can also be erected.

Clause. 6. Wrap dry.

Wearing a "coat" on the tree protects it from wind and cold and protects the plant's own water (newly planted trees).

Clause. 7. Heavy pruning of root flowers and shrubs.

Re-prune the flowers and bury them with soil to ensure that they survive the cold winter.

Clause. 8. Cutting down and digging up dead trees.

Due to a variety of different reasons, such as tree senescence, disease and insect infestation, man-made damage, etc., some trees die, destroying the overall landscape and affecting the landscape. You can use the winter leisure time to cut down dead trees.

Clause. 9. Prevention and control of pests and diseases.

Physical and chemical methods are used to destroy overwintering insect packets, cocoons and larvae. Physical methods include manual hunting, earthquake falling, etc.; Chemical methods include smearing pesticides, spraying insecticides, etc., such as spraying stone sulfur mixture on trees, flowers and shrubs, balls and molds in green spaces to ensure that no pests and diseases occur before the germination of trees in the following year.

The method of watering outdoor plants in winter is as follows:

When watering outdoor plants in winter, you can do it slowly along the 10 cm position of the plant, but you should control the amount of water to avoid too much moisture in the soil.

However, the frequency of watering cannot be generalized, if it is a succulent plant, it can be watered every 15-20 days or so. If you use tap water, you should first dry it in the sun for two or three days. Finally, it is necessary to pay attention to the time of watering, avoid doing it in the morning and evening, and it is recommended to do it at noon.

How to maintain flowers and trees in the open air in winter

1. Watering frozen water and regreening water: water permeable water once before the soil freezes. After the soil contains more water, due to the large heat capacity of the water, the surface ground temperature will not drop too low or too fast in severe winter, and the surface ground temperature will also rise slowly after the beginning of spring.

Due to the large temperature difference between day and night in early spring, timely watering can reduce the temperature difference between day and night on the surface and avoid the spring cold from harming the root system of seedling plants.

2. Wrapping grass and burying soil: For small shrubs, the dead branches and old leaves should be removed first, and then the scattered branches should be tied together with a straw rope, and then the straw with a thickness of 6 to 8 cm should be tied tightly, and finally the mound of soil about 30 cm high should be buried around the nearby ground and photographed. For the flowers and trees in the open field, it is best to cover the ground with hay, straw mats, horse manure, etc. before frost, this method is economical and effective, and it can also be covered with plastic film and other thermal insulation if possible.

3. Protecting the trunk: The commonly used methods are trunk wrapping and whitening. Before and after winter, the trunk of newly planted trees or cold-tolerant seedlings is wound or wrapped with straw rope or sack sheets, etc., and the height can be about 2 meters.

And use the tree guard general to spray the trunk and branches to keep warm, disinfect and prevent frost, hinder the overwintering virus from landing on the tree body to reproduce, restore the life of the fruit tree command system to wake up early, protect flowers and fruits, and can also be mixed with various pesticides.

In winter, try to choose after the morning and before 4 p.m., if it is snowing in the north, do not water, because the temperature is not enough, and the water will frostbite the roots. There are also deciduous trees that have entered hibernation in winter and can be watered without watering, and evergreen trees can be watered less.

Breeze gardening, love gardening, love life. Winter is coming, how to raise plants well, and share with you the experience and methods of watering plants in winter.

Summary. When planting plants in winter, the interval should be longer, because if the temperature is too low, the plants will be temporarily dormant. Keeping green plants is usually better than dry, so after the soil becomes too dry, you can rehydrate the green plants.

When watering in winter, it is best to do it at noon, and it is best to avoid the morning and afternoon, because the temperature will be very low at this time, and if you water it, it is easy to get frostbite on its roots.

In winter, when the green plants are cultivated, the interval between the envy and the seclusion should be longer, because if the temperature is too low, the plants will be temporarily dormant. Keeping green plants is usually better than dry, so after the soil becomes too dry, you can rehydrate the green plants. When watering in winter, it is best to choose to do it at noon, and it is best to avoid the morning and afternoon, because the temperature will be very low at this time, and if the brother sedan chair waters it, it is easy to get frostbite on its roots.
