Rhododendron cultivation methods and precautions

1. Soil: When cultivating rhododendrons, it is necessary to use humus, garden soil and sandy soil to prepare the cultivation substrate. 2. Light temperature:

Place the azaleas in a brightly lit place and keep the room temperature at around 25. 3. Water and fertilizer: Rhododendron peanuts should be topdressed with nitrogen, phosphorus and potassium fertilizers 1-2 times a month for a long time.

4. Precautions: Replace the potting soil for the azaleas every 1-2 years.

1. Cultivation medium

The breeding soil of rhododendron should be made of acidic soil, and the materials such as humus, garden soil, peat soil, and sand should be mixed to ensure that the looseness, ventilation and drainage are good, and the nutrients are sufficient, which can protect the growth of roots.

2. Light and temperature conditions

Rhododendron is not very hardy, so it is better to have a temperature of 10 or more to survive the winter. Rhododendron is a feminine flower, which needs to be maintained under the shade in spring, summer and autumn, and stop shading after late autumn to receive sufficient direct light.

3. Water and fertilizer irrigation

Watering the azaleas during the growing season needs to be moist, and in addition to adjusting the moisture according to the season, it is also necessary to spray water mist to increase the humidity. The root system of rhododendron is shallow, so it is necessary to apply thin fertilizer frequently, mainly with nitrogen, phosphorus and potassium element fertilizer.

4. Precautions

Every 1 2 years of cultivation, it is necessary to change the soil and repot the rhododendron to ensure that the soil is healthy and prevent yellowing. During the growth period, the adventitious buds on the stems and branches should be pruned in time to avoid affecting the overall growth of the plant.

Rhododendron is cultivated as follows:1. Soil, weakly acidic soil. Rhododendron grows like weakly acidic soil, and if the soil is neutral or weakly alkaline, then azaleas are prone to poor growth and even death.

Therefore, when choosing soil, it is suitable to choose humus soil with weak acidity.

2. Sunlight, abundant sunlight. Many people think that rhododendrons are plants that like a cool environment, but in fact, when azaleas are growing, they need enough light so that the branches and leaves will be vigorous and the flowers will be bright. However, when receiving sunlight, it is necessary to refuse the exposure of the scorching sun, and if the sun is strong, it is necessary to provide appropriate shade.

3. Watering, see dry and wet. Rhododendron is very afraid of standing water, because the root system of cuckoos is relatively shallow, and once water accumulates, it is easy to cause root rot. Therefore, watering the rhododendron should adhere to the principle of seeing dry and wet, and start watering when the soil is dry, and watering should be thorough, that is, let the water leak out from the bottom.

Hello! Rhododendron cultivation methods and precautions

Rhododendron is a typical flower that prefers acidic soil, and the pH of the soil is the most suitable. Therefore, when choosing the cultivation soil for azalea potted plants, we must choose acidic soil with good permeability and rich humus.

Cuckoos prefer light. However, it should not be exposed to strong light, especially in summer, and it should be properly covered with half of the light. In other seasons, the light is not very strong. You can give it more light appropriately. This is conducive to the flowering of rhododendrons.

To raise a good cuckoo must be well ventilated, because it likes a lot of air humidity. In the case of good ventilation, you can spray its leaves with clean water in the morning and evening to maintain air humidity. If the air humidity is too dry, it will cause it to dry and yellow leaves, and the leaves will fall.

Rhododendron does not like big fat, especially avoid raw fertilizer and thick fertilizer. You can add an appropriate amount of slow-release fertilizer to the potting soil, and you can use rotted soybean cake water for top dressing. Rhododendron should be frequently applied acid fertilizer to adjust soil acidity and alkalinity, and ferrous sulfate fertilizer should be applied once a week to effectively alleviate the problem of soil alkalinization.

No matter what kind of flower it is, watering is a principle, dry and watered thoroughly. In early spring, you just need to keep the potting soil moist. In late spring and early summer, when it is ready to bloom, the water requirement will increase greatly, so it should be watered a little more.

In the summer, the temperature is too high, and in addition to watering, it is necessary to spray some water on the plants.

In autumn, when the weather becomes cooler, you need to control the water moderately and let the potting soil dry slightly. In winter, when it goes into hibernation, it is necessary to reduce watering. However, different varieties of rhododendrons will have different water needs, if the water is not enough, it is easy to appear yellow and curly at the edge of the leaves, and the leaves will fall off.

The most suitable temperature for the growth of rhododendron flowers is 15-25, and it is necessary to let it grow in this temperature range in spring or autumn. In the summer, when the temperature is relatively high, it is necessary to pay attention to the temperature control, the maximum can not exceed 32, and in the winter when the temperature is relatively low, it should be moved to the house in time, and keep the temperature above 5.

Breeding methods and requirements for the maintenance of the environment

1. Environment, it is best to plant azaleas with two environments: indoor and indoors.

2. Potting soil, rhododendrons like loose and permeable soil, with good drainage and a pH value between 5 and 6.

3. Flower pots, azaleas are usually used in two flower pots: mud pots and purple sand pots.

4. Watering, it is best to use rainwater for azaleas, followed by river water and pond water.

Precautions for rhododendron farming

1. Afraid of dryness, fear of wetness, fear of heavy fat. The roots of rhododendrons are very thin and very few stout, so it is not advisable to overwater and fertilize too much.

2. Place of placement. The place of the azalea is very particular, usually placed on the balcony in the southeast direction, and it should be ventilated frequently and moved less.

3. Prune in time. Prune the residual flowers in time, cut off the diseased branches, damaged branches and long branches to avoid consuming nutrients, and clean up the residual flowers and leaves on the surface of the potting soil.

4. Turn over the pot and change the soil. There is no need to repot every year, it is enough to change the pot once every 2 to 3 years.

5. Pay attention to shading. During flowering, a short period of shade is required, with 40% shading.

It is best to grow azaleas in both indoor and indoor environments. Azaleas spend the winter indoors, with sunlight and good ventilation. In other seasons, it should be placed outdoors, preferably on mud floors, and the venue should be as spacious as possible and properly shaded.

Rhododendron prefers loose, permeable soil, with good drainage, pH between 5 and 6, try not to use clay or alkaline soil. In particular, some species, such as summer cuckoo and cuckoo, can only be used in mountainous soils.

There are usually two types of pots for azaleas: mud pots and purple clay pots.

The mud basin has good ventilation and water permeability, and most of the pots used for outdoor maintenance.

Molded azaleas, not azaleas that have been shaped, usually choose beautiful and elegant purple clay pots. The purple sand basin has a delicate texture, rich color and beautiful shape, which can double the ornamental value.

Rhododendron is best used with rainwater, followed by river water and pond water. But now most households choose tap water, which can be left for 1 2 days to allow chlorine to evaporate before use. A small amount of ferrous sulfate can be added when watering, and it can be watered once every 7 to 10 days during the growing season, and it can be used regularly to keep the soil acidic.

1. Afraid of dryness, fear of wetness, fear of heavy fat. The roots of rhododendrons are as thin as hair, and very little stout, so they are overwatered and the roots are soaked in water; Too little watering, atrophy of branches and leaves; If you apply too much fertilizer and cause serious fertilizer damage, it will be life-threatening.

2. Place of placement. The azaleas are placed in a very particular place, usually on the balcony facing southeast, and should be ventilated frequently and moved sparingly. Different winds are prone to black spot disease, and a large number of leaves fall off.

3. Prune in time. After the flowers are gone, prune the residual flowers in time, cut off the diseased branches, damaged branches and long branches to avoid the consumption of nutrients, and clean up the residual flowers and leaves on the surface of the potting soil. After the new branches germinate, thin the buds and leaves in time, and cut off some of the flower buds and branches and leaves that have grown too densely to ensure air circulation.

4. Turn over the pot and change the soil. Rhododendron grows slowly and does not need to be repotted every year, just once every 2 or 3 years. When changing pots, do not hurt the roots, and replace with half of the new soil. The time for soil change is after the flowers or autumn, and after the soil change, spray Tobuzin solution to prevent pests and diseases.

5. Pay attention to shading. When the weather gets warmer, flower lovers will move the azaleas outdoors (or balconies) for maintenance, and they should see more sunlight from the time they go out of the room to the time they bloom. During flowering, a short period of shade is required, with 40% shading.

Rhododendron cultivation methods and precautions are: soil, temperature, fertilization, pruning, flower pots, etc.

1. Soil

Rhododendron is a shade-loving plant, and direct sunlight is not conducive to its growth, so it is best to choose a place with shade in the shade of the tree shade in the rhododendron special garden, or take this into account when doing green design, and deliberately configure trees in the special garden.

Rhododendron prefers well-drained acidic soil, but because all kinds of special gardens and landscape chains are used for cement roads and paving, the soil of the rhododendron planting site is compacted and alkaline, so the soil of the planting site must be replaced, and a certain amount of peat soil must be added.

2. Temperature

Rhododendron is most suitable for planting in early spring or late autumn, and the root system and soil must be uniform when planting, but not too compact, and the soil surface near the rhizome is arc-shaped, which can not only protect the superficial root system of the plant from severe frost damage, but also facilitate drainage.

In mid to late April, move out of the greenhouse and place it in a leeward and sunny place first, and in summer the reeds are shaded or placed in the shade under the trees to avoid strong direct sunlight. The suitable temperature for growth is 15 to 25, placed in a sunny place in winter, the room temperature is maintained at 5 to 10, and the minimum temperature cannot be lower than 5, otherwise the growth will be stopped.

3. Fertilization

In the late winter and early spring of each year, it is best to apply some organic fertilizer to the rhododendron garden as a base fertilizer. After the rhododendron blooms in April and May, because the plant consumes a lot of nutrients during the flowering period, as the leaf buds germinate and the new shoots lengthen, it can be fertilized every 15 days or so.

After the ambush, most of the branches have stopped growing, and it is the high temperature season, the physiological activity is weakened, and the top dressing can be no longer stopped. After autumn, the climate is gradually getting cooler, and there are autumn rains from time to time, the temperature and humidity are suitable for the growth of rhododendrons, at this time can be done the last top dressing, and it is generally not suitable for fertilization after winter.

4. Pruning

Pruning is an important measure in daily maintenance and management, which can regulate growth and development, so that the growth is vigorous. Daily pruning needs to cut off a few diseased branches and delicate old branches, and delete some overly dense branches in combination with the crown shape to increase ventilation and light transmission, which is conducive to plant growth. For the rhododendron garden, it is necessary to inspect frequently, and if there are dead branches and diseased branches, they should be removed in time to reduce the spread of pests and diseases in the rhododendron.

5. Flower pots

The size of the pot depends on the age of the plant, generally 4 to 6 year old plants with 5 inch pots, 7 to 10 year old plants with 6 inch pots, 11 to 15 year old plants with 8 inch pots, etc. The pots for cultivating rhododendrons can generally be used in mud pots and purple sand pots according to their uses.
