First aid Rhododendron farming, ask for expert guidance

According to your description, I estimate that it is fat, watering more, dry and watered thoroughly, or after the summer it is transplanted into a larger pot to try it, potted flowers do not need so much fertilizer as you said, compound fertilizer can be, and the amount can not be too large, generally fertilize when putting fertilizer in water, pay attention to thin fertilizer diligently. Rhododendron prefers water, and each time you water it, it depends on the wetness of the potting soil.

Lack of sunlight or water, or the lack of indoor air quality in your home

My family also had a young man, commonly known as "can't die", but in my family it died gloriously. I'm ashamed.

In addition, my family is also from Jiangsu, which has nothing to do with the climate, depending on how you raise it. My house is in the kitchen. I didn't move out to bask in the sun one winter, and I guess I lacked photosynthesis and suffocated

Rhododendron is one of the top ten famous flowers in our country. Among all the ornamental flowers and trees, it can be called flowers, leaves and beauty, ground plants, potted plants are suitable, and the most widely used is to push azaleas.

How to raise azaleas? The first thing to do is to understand what it needs to grow and develop. Rhododendron has "six joys" and "six taboos", namely:

Prefer coolness and avoid scorching heat; Joy half-shade, avoid the scorching sun; Prefer moisture, avoid dryness; Prefer acidic soil, avoid alkaline soil; Prefer light soil, avoid clay heavy soil; Prefer good drainage and avoid waterlogging.

After going out of the house in spring, the sunlight is softer, and the azaleas should be properly shaded around noon.

In the summer, the azaleas should be placed in a ventilated and cool place, and in the hot summer, they need to be shaded with reed curtains, bamboo curtains, and sunshade nets, and the curtains should be opened before 8 o'clock in the morning and after 5-6 o'clock in the afternoon. Because rhododendrons are semi-negative flowering trees, young leaves are easily burned under the scorching sun. If it is exposed to strong direct sunlight for a long time in summer, it will cause the branches and leaves to wither and yellow, stagnate growth, and in severe cases, the whole plant will die.

In autumn, the intensity of sunlight gradually eases, before 9 a.m. and after 5 p.m., the azaleas can see more sunlight, and in late autumn, they can be placed in a sunny place to promote flower bud differentiation. Rhododendron is not cold-tolerant, so it should be moved indoors and placed in a sunny place between cold dew and frost. At the beginning of entering the room, attention should be paid to opening windows and doors for ventilation.

If it is placed in the shade for a long time, it is easy to drop buds.

In winter, the room temperature should be around 10. The room temperature of most varieties is not lower than 5, but the room temperature of the American cuckoo is cold, and the room temperature cannot be lower than 8 for wintering. If the room temperature is too high in winter, the metabolism will be enhanced, and nutrients will be consumed, which is not conducive to the growth and development of the next year.

Soil for azaleas can be used to maintain acidic soils. Because rhododendrons like acidic soils, they are thought to be suitable. The potting soil is required to be loose, well drained, and contain humus.

6 parts of humus soil, 2 parts of peaty soil, and 2 parts of river sand are commonly mixed or prepared with pine needle soil. At the same time, in order to improve the quality of water, it is best to use mineral-free water, such as rain or snow water. In addition to storing rainwater and snow water, acidified water can be used, that is, 100 catties of water and ferrous sulfate for perennial watering.

If the acidity is not enough, you can supplement it with a small drop of vinegar. How to water:

1) To use"Trapped water", that is, the water is dried in a place at the same temperature as the cuckoo. It can also be used with fish tank water, rainwater, and river water.

2) The soil is not dry or watered, and it is not too dry, as the leaves will wilt.

3) Pour it thoroughly.

4) There is a difference between winter and summer. The leaves are good in winter, and wet spots in summer are fine. It is not advisable to water more during the flowering period, as it is easy to fall buds and harvest early; The wind is dry in spring and autumn, and it must be sufficient.

Be careful to spray foliage and ground to maintain a certain humidity. In the growth period of rhododendron, alum fertilizer water is generally applied once every 10-15 days, and foliar sprays can also be carried out with potassium dihydrogen phosphate solution.

It may be that there is still too much fertilizer. Because it has been damaged, the leaves will eventually fall. Remedy: Rinse with water several times and place in a cool place to recover.

In my family, I usually sprinkle water every evening and don't give fertilizer. It's a good life.

1. Sufficient light: Place the azaleas in the semi-shade to receive astigmatism. 2. Moisture management

When you notice that the soil is dry, replenish the azaleas immediately, taking care not to accumulate water. 3. Scientific fertilization: apply well-rotted organic fertilizer in time during the peak growth season and flowering period of the plant.

4. Suitable soil: replace the potting soil every 1-2 years to avoid soil compaction.

1. Sufficient light

Rhododendron likes light, but not sun-resistant, it is recommended to put it in a semi-shaded place during the maintenance period, accept astigmatism irradiation, can not be placed in a shaded environment for a long time, otherwise it can not carry out photosynthesis normally, and the branches and leaves are easy to grow, affecting the later flowering.

2. Moisture management

The root distribution of rhododendron is shallow, not resistant to waterlogging, and drought tolerance is also very poor, in the process of breeding, when the soil is found to be dry, it is necessary to immediately replenish the water, pay attention to the water must not appear, otherwise it is easy to dip the roots, affecting the normal respiration of the root system.

3. Scientific fertilization

Rhododendron in the growing season and flowering period of nutrients demand is large, these two time periods need to be timely top dressing, fertilizer selection of rotten organic fertilizer, and before flowering to the foliar spray of potassium dihydrogen phosphate fertilizer, to promote better flowering of plants.

4. The soil is suitable

When cultivating rhododendrons, soft, breathable, fertile and slightly acidic soil should be used, it is recommended to mix humus, river sand and base fertilizer in the garden soil, and the potting soil needs to be replaced every 1-2 years during the maintenance period to avoid soil compaction.

1. Suitable temperature.

In the method and precautions for the cultivation of rhododendrons, the temperature should be controlled between 12 and 25, so that the growth of rhododendrons can be more lush. In winter, it is necessary to do a good job of keeping warm and cold, and keep the temperature at about 10.

2. Shading and maintenance.

For the shade-loving rhododendrons in the breeding should also do a good job of shading and shading maintenance, in the sun is more strong should be shaded in time to avoid rhododendrons being sunburned, in winter to make it accept full sunshine, when the rhododendron grows better.

3. Apply thin fertilizer frequently.

When breeding rhododendrons, thin fertilizer should be applied frequently, so that its small shallow roots can better absorb nutrients to support the vigorous growth of rhododendrons, generally about 10 15 days to apply a thin Bika water-soluble fertilizer, flowering period to stop fertilizer to keep it in a good ornamental state.

4. Loosen the soil and change the pot.

Every 2 years, the rhododendron needs to be loosened and repotted, and the new soil is generally replaced after the flowering, and the garden soil, river sand and humus can be prepared according to the ratio of 1:1:8, so that the azalea can grow better.

Prepare soil rich in organic matter to ensure the permeability of the root system. The environment should be warm and comfortable, and spray and ventilate regularly. Watering in time, at the right time and in the right amount, so that the dry and wet cycle of the potting soil is regular.

Thin fertilizer is applied frequently, and rice water is skillfully used to supplement acidity. Prune and pick flowers in time to make use of limited nutrients for flowering and leaf growth.

Rhododendron is a deciduous shrub of the genus Rhododendron in the Rhododendron family, 2-5 meters high, with many and slender branches. The leaves are leathery, often clustered at the ends of the branches, ovate, elliptic-ovate or obovate, the front end is short and gradual or rounded and pointed, the leaf margins are slightly reversed and finely toothed, dark green above, pale white below; The corolla is broadly funnel-shaped, obovate, and generally 2-6 clusters are born at the top of the branches.

Rhododendron has a wide range of medicinal value, according to the "Dictionary of Traditional Chinese Medicine" and other relevant Chinese medicine literature: Wang Ma Rhododendron has a sweet and sour taste, has the effect of invigorating blood and regulating menstruation, and can treat bruises, rheumatism, joint pain and other diseases; Because of the bright red color of the corolla, it can be used as a flower plant and has high ornamental value; The cuckoo can also monitor toxic gases.

When cultivating rhododendrons, it is necessary to control the ambient temperature between 18 degrees and 25 degrees, and it is also necessary to do shade measures for the azaleas when the light is too strong, and it is also necessary to apply diluted thin fertilizer every half a month to provide nutrients for the growth of the rhododendrons, and the soil needs to be replaced every three years to make the azaleas grow vigorously.

1. Suitable temperature.

Rhododendron is suitable for growing in a warm environment, when breeding rhododendrons, if the ambient temperature is too low, it will cause the plants to be frostbitten, so that the rhododendrons grow poorly, when the weather is cold, the azaleas need to be moved to a warm room for maintenance, and the ambient temperature needs to be controlled between 18 degrees and 25 degrees.

2. Lighting conditions

When cultivating rhododendrons, if the light is too strong, it will cause the plants to be sunburned, which will make the branches and leaves of the azaleas yellow, and it is necessary to do shade measures for the azaleas in the middle of summer to make them grow healthily, and it is also necessary to move the azaleas outdoors in spring and autumn to allow them to receive all-weather natural light to promote the vigorous growth of azaleas.

3. Provide nutrients

Rhododendron needs sufficient nutrients in the growth process, when breeding rhododendrons, it is necessary to apply a diluted thin fertilizer every half a month, and the fertilizer can not be sprinkled on the branches and leaves of the rhododendron when fertilizing, so as to avoid the yellowing and drying of its flowers and leaves, and it is also necessary to use sharp scissors to cut off the buds of the rhododendrons with poor growth to avoid the loss of excess nutrients.

4. Replace the soil

During the daily maintenance of rhododendrons, if the soil becomes stiff and stiff, it will lead to poor respiration of the root system of the rhododendron, which will make the leaves of the azalea yellow and wilted, and the soil needs to be replaced every three years.

The method of raising and rearing rhododendrons is as follows:

1. Sunlight: Rhododendron is not suitable for exposure to the sun, but it can be grown under scattered light. Too much sunlight can cause leaf burns, leaf edge wilting, and death. Therefore, it must be shaded in time at noon in summer, or put in a semi-shaded place.

2. Soil: Rhododendron has certain requirements for soil, in addition to good drainage, it is best to be acidic. Generally, it is mixed with humus and sand, and a small amount of Hengque cake fertilizer is introduced as base fertilizer.

3. Watering: Rhododendron watering can neither dry nor damp, just keep the soil slightly moist. Generally in spring and autumn, water every two to three days.

It needs to be watered every day in the summer and dried again in the winter. The water quality should also be strictly controlled, and the temperature should be close to room temperature before using ferrous sulfate or acetic acidification.

4. Fertilization: Fertilization of rhododendrons is very demanding. At the beginning of spring, organic fertilizer can be added to the pot as a base fertilizer.

After flowering, top dressing is done once every 15 days. When the branches stop growing a little, you can stop fertilizing. Top dressing once in autumn is conducive to overwintering, while fertilization is not suitable in winter.

Precautions for cultivating rhododendrons

1. Apply thin fertilizer frequently. It needs nutrient support to grow, so it needs to be regularly fertilized to it. However, when fertilizing, you need to dilute the fertilizer in advance to prevent too concentrated fertilizer from burning its roots.

2. Timely pest control. During the growth process, it may develop some pests and diseases. Once it is found that it needs to be sprayed in time**, it cannot be left unattended, otherwise it may cause a wide range of plant death.

1. Breeding environment.

Breeding rhododendron can not be placed in the hot and cold environment, it likes to grow in a semi-shaded, cool, humid environment, spring breeding rhododendron to control the temperature at about 18, its best growth suitable temperature in 12-25. Pay attention to temperature control in summer, more than 32 will affect the growth of plants.

2. Prune the plants.

The growth of rhododendrons is slow, and the oak is pruned after its flowering, mainly by cutting off some long branches, and cutting off the deformed branches of the diseased branches, and pruning should be thin. If it is a 2-4-year-old plant, it is necessary to cut off its flower buds, which can help it quickly form a more skeleton, which is conducive to its subsequent growth and flower formation.

3. Water and fertilizer management.

When potting rhododendrons, watering should be appropriate, and the azaleas should not be watered too much during the rhododendron flowering period, and the flowers should be prevented from withering in advance. In summer, the amount of water evaporation is large, the air is relatively dry, and it is necessary to water 1-2 times a day, and reduce or stop watering in winter. Master the correct fertilization method, apply the appropriate amount of phosphorus and potassium fertilizer before flowering, and stop fertilizing in hot summer and cold winter season.

Precautions: There is no fixed frequency of watering rhododendrons, and the frequency and amount of watering need to be adjusted in time according to the dry soil conditions, seasonal climate and plant needs. In addition to watering, if you want azaleas to grow vigorously, you need to pay more attention to light, temperature, and fertilization, so that the azaleas can grow strong and bloom brightly.

There are many methods and techniques of rhododendron cultivation, which mainly involve water and fertilizer management, enhancement and quality improvement, variety selection, etc. Water and fertilizer management: Rhododendron likes a humid environment, they need sufficient water and the right amount of fertilizer, so they should be fertilized and watered in time to maintain a good cultivation environment.

Enhancement and quality improvement: Frequent grass control, fertilization, etc., can help the ornamental value of rhododendrons, and can improve the quality of varieties, making them look more beautiful. Breed selection:

When buying rhododendrons, you should choose the appropriate varieties according to your own garden environment, such as bright rose azaleas, red azaleas, etc., they all have bright flower colors, which will add a strong color to the garden. Through the above methods and techniques, we can make our azaleas more beautiful and more appreciative.
