How to raise azaleas, how to raise azaleas

Rhododendron is a neutral flower that prefers warm, semi-shaded, cool, ventilated, and moist environments. It is required to be loose, fertile, humus-rich acidic (loess) soil, with a pH value between to, and avoid alkaline or clayey soil. The suitable growth temperature is 12 to 25, in summer to shade the sun and protect from the sun, in winter to prevent freezing and keep warm, it is best to move indoors, especially the more delicate rhododendrons such as Western rhododendrons, more attention should be paid to maintenance.

Now the author's practical experience in cultivating azaleas in the past few years is introduced to you for reference

1 The rhododendron's roots are as thin as a hair, and the thick taproots are few, and it is afraid of both dryness and moisture, especially heavy fat. If you water too much, the roots will be soaked in water, too dry, the branches and leaves will shrink, and the leaf petals will fall off, which is a great threat to the plant, and as for watering heavy fertilizer, it will be life-threatening.

2 After the flowering, the residual flowers must be cut off to avoid fruiting and consuming nutrients, and after the new branches germinate, the branches should be properly thinned and left according to the growth of the plant.

3 Rhododendron is best planted in muddy pots, because the mud pots absorb water and breathe, which is conducive to the growth and development of the root system and the flourishing branches and leaves.

4 Potted azaleas should be placed on the southeast balcony carefully, and should be ventilated and moved as little as possible. If it is not ventilated, it is susceptible to black spot disease and a large number of leaf litter.

5 The cuckoo should also have moderate light requirements, and avoid direct light in summer. Fertilization should be mastered thin fertilizer diligently, can be light, and apply organic compound fertilizer on the potting soil once a month. Potassium dihydrogen phosphate was sprayed every 10 days for extra-root fertilization.

Water at the right time, and you can also add vinegar to the water to increase acidity.

6. Thin the buds and leaves in time, remove part of the flower buds and leaves that have grown too much and too dense, so that the air can circulate and the nutrients will be concentrated in the flower buds. After the flower buds are formed, it is necessary to increase the nutrients and apply more phosphorus and potassium fertilizers in an appropriate amount, otherwise the flower buds will be transformed into leaf buds.

7 The main reasons for the loss of leaves and non-flowering of azaleas are: too strong direct light in summer, severe cold and frostbite, too much watering, too much fertilization, too long time indoors, placed in a dark and damp place with poor air circulation, drenched acid rain, etc., so these situations should be avoided during the maintenance process.

8. Turning over the pot and changing the soil, do not need to be carried out every year, generally once every 2 to 3 years, try to damage the roots as little as possible, and the time should be after the flowering or autumn, and at the same time spray Tobuzin to prevent diseases.

9 The insect pests of rhododendrons are mainly red spiders, aphids, etc., which can be sprayed with pyrethroid, etc., and the effect is better, such as not dying after three days, spray again. The disease is mainly melanoma, which is caused by a stuffy environment and lack of light, and measures can be taken to promote air circulation on the one hand, and spray Bordeaux liquid and carbendazim on the other hand.

10 The main method of propagation of azaleas is cuttings. Before and after the selection of new branches, 5 cm to 10 cm long, cut at the fork point, peel off the lower leaves, leave 3 to 4 top leaves, insert 1 3 of the branches into the soil, spray enough water, cover with plastic film. Usually to strengthen management, transplant after one year.

1. Light: Rhododendron breeding process should ensure that its light is sufficient at any time, because the light is sufficient to bloom well, of course, it can not be taken out to expose to the sun in the hot summer, but should strengthen the work of shading, in order to prevent sunburn, in addition, in the flowering season should also be properly protected, can be protected by light blocking nets, and the flowering period can not be exposed.

2. Fertilization: Proper fertilization can make rhododendron breeding grow thicker and faster, and most indoor flower farming, the fertilization principle of rhododendron is also thin fertilizer and more application, that is, a little less at a time, you can apply more times. At.

The old leaves turn green, during flowering, after flowering, appropriate fertilization two to three times, during the hot weather, must not be fertilized. Rhododendron cultivation and fertilization can be used grass juice water, fishy water, rapeseed cake and other materials. In addition, if a diseased branch is found, it should be pruned in time to prevent it from affecting the health of other branches.

How do I raise rhododendrons?

Rhododendron is a perennial woody plant, likes cool and humid climate, likes semi-shade and avoid exposure to the sun, likes fat and avoids thick fertilizer, and is suitable for growing in permeable and breathable slightly acidic sealed soil. Therefore, rhododendrons grow most vigorously around 20; Above 30, it stops growing and is dormant; If you are on the job, you will not freeze to death. But I am afraid of a sudden attack by the cold wind.

Therefore, azaleas should be kept indoors away from heating and stoves, and can receive plenty of sunlight in winter, and in summer, they should be shaded on a well-ventilated north balcony (or outside the north window). Watering is like other flowers, wet and dry, often lack of water will affect growth, too much watering will rot roots, resulting in death. Water twice a day in the summer, once a day at other times, and only once a few days in the winter, depending on the situation.

The water for watering flowers should be left for a few days before use, and every 10-15 days to water the ferrous sulfate to be concentrated, or a few drops of edible vinegar in the water can also be used. Fertilization is carried out in line with the principle of "thin fertilizer and diligent application", and the finished flower fertilizer is prepared and used according to the regulations, and the fertilizer made by themselves should be lightly added to the water combined with watering, and no fertilizer is applied during flowering. Fountain fog 2-3 times a day to increase humidity.

The flower soil should be made of special soil prepared by larch. Rhododendron can bloom in all seasons, and the flowering period is relatively long, as long as the cultivation conditions are suitable, from the first flower to the full bloom can be up to more than three months. According to the need, generally let it bloom before the Spring Festival, at this time, nature has lost its green, the flowers are gone, and during the festive season, buy a few pots of azaleas, whether it is for their own appreciation or to relatives and friends, it is the best choice.

Rhododendron maintenance method:

1. Rhododendron prefers light, but it cannot be exposed to strong light, especially in summer, and it should be properly covered with half of the light;

2. The root system of the rhododendron is a relatively shallow root system, and it is more afraid of dryness and waterlogging, so we can pick it with our hands to water it;

3. In the growing season of rhododendrons, give it fertilizer with complete nitrogen, phosphorus and potassium elements every 10 days or so.

Rhododendron belongs to the flowers of the south, and it is more difficult to maintain in the north, but as long as you find out its growth habits, you can also maintain it well according to its habits.

The value of azaleas: ornamental effect: blooming flowers in spring, lush green leaves in autumn, and red in autumn and winter; Medicinal value: dispel dampness and regulate blood, treat phlegm and cough, and treat bruises.

First, the breeding method:

1.Sunlight: Rhododendron flowers are not suitable for exposure to sunlight, but they can be grown in diffused 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 the soil, preferably acidic, in addition to good drainage. Generally, it is mixed with humus and sand.

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.

4.Fertilization: Fertilizing azaleas is very demanding. At the beginning of spring, organic fertilizer can be added to the pot as a base fertilizer. After flowering, top dressing every 15 days. <>

When <> breeding rhododendrons, it should be placed in an environment with sufficient astigmatism, keep the leaves green, and in the case of dry soil, timely water the rhododendrons to keep the soil moist, and provide nitrogen fertilizer, phosphorus and potassium fertilizer for it during the growth period to improve the growth rate of the plant and make the azalea grow vigorously.

1. Provide light.

Rhododendron likes light and is afraid of the sun, and it should be placed in a bright environment when breeding, so as to provide sufficient astigmatism for the plant and maintain the growth of the azalea, but the light is weak in winter, at this time it can be put into the sunny window or balcony, so that the plant receives full sunshine.

2. Replenish water.

Rhododendron has a greater demand for water, and it is necessary to water the soil once a week to soak all the soil when breeding, but when the temperature is higher in summer, it should be watered once every three days to avoid soil compaction, and it is also necessary to spray water mist on the leaves to improve the humidity of the environment.

3. Scientific fertilization.

When breeding rhododendrons, the choice of fertilizer should be decided according to its growth state, in the long-term of rhododendron peanuts, nitrogen fertilizer, urea-based fertilizer should be used to improve the growth rate of the plant, after the rhododendron enters the flowering period, it should be provided with phosphorus and potassium fertilizer, so that the plant blooms beautiful flowers.

4. Disease prevention and control.

Rhododendron has poor disease resistance, so it should be sprayed with carbendazim every two months to eliminate the bacteria on the plant, and clean up the dead branches and leaves dropped by the roots of the rhododendron to avoid bacterial breeding. If the disease has already appeared, the infected branches should be cut off to allow the azaleas to grow healthily.
