Rhododendron how to water in winter, how to water azaleas

The root system of rhododendron is a shallow root slender root group, which is afraid of drought and waterlogging, and improper watering will cause it to fall off its leaves and die at worst.

Rhododendron watering should be based on plant growth and weather changes. During the spring pregnancy bud and flowering period, water consumption is more, and watering should be timely. Otherwise, the pot will be dehydrated, the flowers will wither, and the flowering period will be shortened.

At this time, it is advisable to keep the potting soil moist. In summer, the rhododendron branches and leaves grow vigorously, the temperature is high, and the water evaporates quickly, in addition to watering once a day, water should also be replenished at any time. If the potting soil is too dry, the leaf color will turn yellow, the center of the leaf will curl, and even dry up and die.

Autumn flower buds have formed, just keep the potting soil dry. In winter, the temperature is low, the rhododendron is in a dormant or semi-dormant state, the water consumption is low, and the watering should be strictly controlled, otherwise it is easy to rot the roots. However, it should be noted that at this time, the branches and leaves should be sprayed with water close to room temperature every 1 week or so to facilitate the freshness of the plant and reduce the occurrence of soot disease.

When watering rhododendrons, pay attention to the quality of water, and the use of rainwater is very suitable for their growth. In Tohoku and other places, azaleas are watered with snow water, and the effect is also very good. However, care should be taken to leave the snow and ice melt until it is close to room temperature before use. If tap water is used, it must be stored in a bucket for 1 day before use.

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.

Fertilization is the key to raising rhododendrons, like fertilizer and avoid thick fertilizer, in the spring and autumn growing season every 10 days to apply 1 thin cake fertilizer liquid water, can be used to wash rice water, peel, vegetable leaves, etc. In autumn, you can also add some phosphorus and potassium fertilizer, which can be made by using the offal of fish and chicken, washing water and rice washing water and some fruit peels. In addition to the above-mentioned homemade household fertilizers, you can also buy some household fertilizers to use together, but remember to use "thin" fertilizers.

Apply 1 dry fertilizer (a small amount) before winter, and do not apply pot bottom fertilizer when changing pots. In addition, whether it is watering or fertilizing, do not use tap water directly, but acidify it (add ferrous sulfate or vinegar), and use it when the pH value reaches about 6.

It is best to use rainwater for watering rhododendrons, followed by river water and pond water.

If tap water is used, it is advisable to store the water for 1-2 days to allow the chlorine to evaporate before use.

In addition: add ferrous sulfate when using, water once every 7-10 days during the growing season, and use it frequently to ensure that the soil is acidic.

"Cuckoo" is weak in cold resistance, and the temperature drops below 0 in winter, and it is prone to frost damage. Therefore, it is necessary to take measures to protect against freezing and cold. In winter, the rhododendron grows slowly and enters a semi-dormant state when it is cold, so the humidity of the potting soil is better to be moist and slightly dry, and the soil with high humidity will reduce the soil temperature, but it cannot be allowed to dry out, which is not conducive to root growth.

Outdoors, it is best to wrap a pot with straw or hay, and cover the surface of the potting soil with some hay to keep warm. If conditions permit, it can be buried in the soil for wintering.

If you can't raise azaleas well in winter, master the skills of watering and fertilization, and it is easier to germinate new branches and buds.

1. Watering method: When watering azaleas, you need to let the water flow down the edge of the pot and flow out from the drainage hole at the bottom of the pot. 2. Watering frequency:

Water 2-3 times a week in spring and summer, and every 1-2 weeks in autumn and winter. 3. Water quality: water azaleas with pollution-free rainwater, mineral water, pure water or dried tap water.

1. Watering method

The first thing to ensure when watering rhododendrons is that in any case, the potting soil should not be soaked with water and rotten rhizomes, nor should it be caused by long-term drought due to non-watering. The method of "watering when dry" is more correct, so that the potting soil can maintain a healthy moistness, and the amount of water is adjusted according to different seasons and plant growth cycles.

2. Watering in all seasons

There is a certain difference in the frequency and amount of watering of azaleas in four seasons. Spring and autumn belong to the growing period, the growth rate is faster, and it is watered every 2 3 days. In summer, the climate is hot, and water evaporates easily, so water once in the morning and once in the evening, and spray water mist on the plants to increase humidity.

In winter, the climate is lower, so in order to avoid frost damage, it is enough to water once a week to half a month.

3. Water quality selection

The water used to water the rhododendrons can be clean rainwater or snow water collected in nature, or mineral water or purified water can be used for irrigation. However, most of the time you use tap water to water your flowers, and you need to let it stand for 1 or 2 days and wait for the chlorine gas to volatilize before you can use it with confidence.

4. Deal with water hazards

If you accidentally water the azalea when watering too much and there is water damage, you should move the azalea to a ventilated and high-quality environment as soon as possible, and loosen the soil to drain the water in the potting soil to alleviate the overhumidity. Wait until the rhododendron humidity returns to normal before rewatering and irrigating.

Water azaleas in spring and autumn, you can water them every 2-3 days, the temperature is higher in summer, you should water them once a day in the morning and evening, reduce watering in winter, and water the azaleas to follow the principle of watering when you see dryness, water mineral water and pure water for it after the potting soil is dry, stop the water in time after the water accumulates, and shovel the loose soil to discharge excess water.

The first thing to make sure when watering rhododendrons is that the potting soil must not be waterlogged, otherwise it is easy to rot the roots, and it cannot be dry for a long time, otherwise the roots will dry up. To maintain the watering principle of "watering when dry", keep the potting soil a certain degree of moisture, watering is best gradual, a small number of times of slow penetration.

Rhododendron has different growth needs in different seasons and consumes different amounts of water. Spring and autumn belong to the growing season, and the water demand is large, so it is watered every 2 3 days. In summer, the climate is hot and the water is consumed quickly, so water once in the morning and once in the evening, and spray the plants with water mist to increase humidity.

In winter, when temperatures are low, watering should be reduced.

Azaleas can be watered with natural rain or snow water, mineral water or purified water, and the best water quality is slightly acidic water with a pH of 7 or less. If you use household tap water, be sure to dry it for 1 or 2 days to eliminate chlorine before using it, the water that removes chlorine is more conducive to the absorption of nutrients by the roots.

If there is too much water and water accumulation occurs when watering azaleas, it is necessary to move the azaleas to a ventilated and light environment as soon as possible, deal with the water in the pot, and loosen the soil in time to breathe, speed up the evaporation of excess water, avoid the rot of the soaked roots, and replace the potting soil if necessary to restore the humidity to a normal state.

1. Spring and autumn: Water the azaleas 2-3 times a week to keep the soil moist. 2. Summer:

Water evaporates quickly, so hydrate the azaleas every day and spray mist all around. 3. Winter: When the temperature decreases, the moisture can be reduced, and it is watered every 10 days.

4. Precautions: Watering in summer should not be carried out at noon.

1. Spring and autumn

Spring and autumn are the most suitable for the growth of rhododendrons, when the growth rate of the plants is very fast and the demand for water is very high. Water according to the dryness and humidity of the soil to keep the soil moist, normally 2 to 3 times a week.

2. Summer:

In summer, water evaporates very quickly in the high temperatures, so in order to avoid drying out, it is necessary to replenish water in time during this time. Except for continuous rainy days, the plants need to be watered every day and sprayed around the plants frequently to control the ambient humidity.

3. Winter

In winter, when the temperature is very low, the growth rate of the plants slows down, and the need for water is reduced, so it is advisable to reduce the watering of the plants and keep the soil dry, and it is advisable to water every 10 days under normal circumstances.

4. Precautions

When watering rhododendrons, pay attention to the watering time, high temperature watering in summer must be carried out in the early morning or evening, and low temperature watering in winter must be carried out after the temperature rises at noon. In addition, rhododendrons are acid-loving flowers, and rain is more suitable for plant growth, so you can use containers to store part of the water for irrigation on rainy days.

1. Spray: Because azaleas like moisture, you can use spray when watering to create a moist environment for it while replenishing water. This is more conducive to its growth.

2. Flood irrigation: Water from the edge of the pot, and wait until there is water flowing out of the drainage hole at the bottom, which proves that it has been watered thoroughly.

3. Hydration: In the case of a large pot and weak indoor ventilation, it is very likely that the potting soil has dried up, but the inside is still wet. At this time, just properly hydrate the dry part on it and let it moisten.

4. Sitting on water: If conditions permit, you can use sitting water regularly to replenish water for it. Find a pot larger than the pot, pour in clean water, soak 1 2 of the pot in water for 2-3 minutes, let the water seep into the soil from the bottom hole.

In spring and autumn, it is best watered in the morning and evening, and in summer, it is best in the early morning or afternoon an hour after the sun sets. In winter, it is best to water between 10 a.m. and 2 p.m.

The water for watering the azaleas should be clean and clean. Because it is sensitive to salt, if the salt content of the water is high, its growth will be inhibited and the root system will also have problems, so it should be watered with water with a lower salt content. In addition, it prefers slightly acidic water, and the pH value should be adjusted when watering to meet its needs.

When watering, pay attention to the temperature of the water so that it is close to the temperature of the potting soil to avoid unnecessary damage.

Watering should be appropriate and keep the potting soil slightly moist. The soil should not be allowed to dry out, nor should it be allowed to accumulate water in the soil.

Rhododendron watering: water once every three or four days in the spring and autumn growing season, moisturizing treatment.

Rhododendron prefers moist environments, so it should be watered more frequently. In the spring and autumn growing season, the three drafts are watered once every four days and moisturized. In summer, it is very hot and it is necessary to water almost every day.

In winter, the temperature is low, and the growth has basically stopped, so it is necessary to control the water, not dry and do not water. It is a semi-shady environment, and it is usually placed in a low-light place. The growing season consumes a lot of nutrients, and if you want it to grow vigorously, you need to top dressing in time to ensure that the nutrients are sufficient.

In addition, it has very poor cold tolerance, and it is necessary to control the low temperature in winter well.

Precautions for breeding:

Rhododendron prefers semi-shady environments and is afraid of bright light. During the curing period, it can be placed in a low light place to meet the need for light. Direct light or strong light must be blocked in time, not exposed to the sun, otherwise it is easy to sunburn. It is also not good to leave it in the shade for a long time, it will affect flowering.

Rhododendron consumes a lot of nutrients in the peak growing season, and if you want it to grow and bloom better, you need to top dressing in time. At the beginning of germination, fertilizers containing nitrogen are applied to promote the germination of branches and leaves. Before flowering, fertilizers containing phosphorus and potassium were applied to promote flower bud differentiation.

After flowering, organic fertilizer needs to be applied to replenish the nutrients consumed.
