What are the methods for growing azaleas as potted plants at home?

The azalea is one of the top ten famous flowers of our country. Among all ornamental flowering trees and shrubs, the one that can be called beautiful in both flower and leaf, suitable for both ground planting and potted cultivation, and the most widely used, is the azalea.

The azalea has always been a flower that everyone likes rather a lot, and surely many people have grown azaleas, but many people may not be very clear about how to grow azaleas. Today I will introduce the relevant techniques and methods for growing azaleas, hoping to be of help to everyone when growing azaleas.

Below is an introduction to how to grow azaleas well

How do you grow azaleas well? First you need to understand the conditions required for their growth and development. Azaleas have the "six likes" and the "six taboos."

① Likes coolness, avoid extreme heat

② Likes partial shade, avoid scorching sun

③ Likes moisture, avoid dryness

④ Likes acidic soil, avoid alkaline soil

⑤ Likes light-textured soil, avoid heavy clay soil

⑥ Likes good drainage, avoid waterlogging.

After being moved outdoors in spring, when the sunlight is relatively soft, azaleas should be properly shaded around midday.

After summer arrives, azaleas should be placed in a ventilated, cool spot, and in the hot summer they need to be shaded with reed blinds, bamboo blinds or shade netting, with the blinds opened before 8 in the morning and after 5-6 in the afternoon. Since azaleas are semi-shade-loving flowering shrubs, the tender leaves are easily scorched under blazing sun. If kept under strong direct light for a long time in summer, the branches and leaves will turn yellow and withered, growth will stall, and in severe cases the whole plant will die.

In autumn the intensity of sunlight gradually softens, so before 9 in the morning and after 5 in the afternoon azaleas can be given a bit more sunlight, and in late autumn they should be placed in a sunny spot to promote flower bud differentiation. Azaleas are not cold-tolerant, and between the Cold Dew and Frost's Descent periods they should be moved indoors and placed in a sunny spot. In the early stage after being brought indoors, care should be taken to open the windows and doors for ventilation. If they are kept in a shaded place for a long time, they are prone to dropping their buds.

In winter the room temperature should preferably be around 10°C. For most varieties the room temperature should not be lower than 5°C, but Western azaleas are sensitive to cold, and the overwintering room temperature cannot be lower than 8°C. If the winter room temperature is too high, metabolism increases, nutrients are consumed, and this is unfavorable for growth and development the following year.

Acidic soil can be used for the soil used to care for azaleas. Because azaleas like acidic soil, a pH of 4.5-6.5 is suitable. The potting soil is required to be loose, well-drained and rich in humus. A commonly used mix is 6 parts leaf mold, 2 parts peat soil and 2 parts river sand blended evenly, or pine needle soil can be used. At the same time, in order to improve the quality of the water used, the water for watering the flowers is best water that does not contain minerals, such as rainwater or snow water. Besides storing rainwater and snow water, acidified water can be used, that is, 100 jin of water with 0.1% ferrous sulfate added, used for watering all year round. If the acidity is not enough, a few drops of vinegar can be added to supplement it. How to water:

(1) Use "aged water," that is, let the water stand and be exposed to the air at the same temperature as the azalea. Water from a fish tank, rainwater, or river water can also be used.

(2) Do not water if the soil is not dry, and do not let it get too dry either; if it is too dry the leaves will wilt.

(3) When watering, water thoroughly.

(4) Winter and summer are different. In winter the leaves are fine, and in summer being a bit moist does no harm. During the flowering period it is not suitable to water too much; too much easily causes bud drop and early withering; in spring and autumn when it is windy and the air is dry, sufficient water must be ensured. Be careful to spray the leaf surfaces and the ground to maintain a certain humidity. During the growing period of azaleas, generally apply ferrous sulfate fertilizer water once every 10-15 days, and a 0.1%-0.2% potassium dihydrogen phosphate solution can also be used alternately for foliar spraying.

Points for attention:

1. The roots of azaleas are as fine as hair strands, with very few thick main roots; they fear both drought and waterlogging, and especially fear heavy fertilizer. If watered too much, the roots soak in water; if too dry, the branches and leaves shrivel and the leaf petals fall off, which is a great threat to the plant; as for applying heavy fertilizer, it can endanger their lives.

2. After the flowers fade, the spent flowers must be cut off to avoid seed formation consuming nutrients; after new branches sprout, thin the branches appropriately, deciding what to keep and remove according to the plant's growth vigor.

3. Azaleas are best planted in clay pots, because clay pots absorb water and breathe, which is beneficial to root growth and development and makes the branches and leaves luxuriant.

4. There is particularity in where potted azaleas are placed; generally they should be placed on a southeast-facing balcony, and it must be ventilated, moving them as little as possible. Without ventilation they are prone to black spot disease and lose a large number of leaves.

5. Azaleas' light requirements should also be moderate, and direct light should be avoided in summer.

6. Thin buds and leaves in time, removing part of the flower buds and leaves that have grown too many and too dense, so that air circulates and nutrients are concentrated in the flower buds. After the flower buds form, nutrition should be increased, applying a suitable amount of extra phosphorus and potassium fertilizer, otherwise the flower buds will turn into leaf buds.

7. The main reasons azaleas drop their leaves and fail to bloom are: too strong direct light in summer, frost damage from severe cold, too much watering, too concentrated fertilizing, being kept indoors for too long, being placed in a place with no air circulation or a dark, damp place, being rained on by acid rain, etc., so these situations should be avoided during care.

8. Repotting and changing the soil does not need to be done every year; generally once every 2 to 3 years, damaging the roots as little as possible, and the time should be after the flowers fade or in autumn, and at the same time spray thiophanate to prevent disease.

9. The main insect pests of azaleas are the azalea lace bug, the bud-rolling leaf roller, red spider mites, aphids, etc., which can be sprayed and killed with fenvalerate, etc., with good results; if they are not dead after three days, spray again. For the azalea lace bug (also known as the azalea lace bug, Stephanitis) during the damage period, spray a 1500-fold dilution of 40% dimethoate, once every 7 days, for 3 consecutive times. The control method for the bud-rolling leaf roller mainly relies on manual capture and killing, and the larvae or pupae can also be sprayed and killed with a 2000-fold dilution of 40% dimethoate emulsifiable concentrate or a 1500-fold dilution of dichlorvos.

10. The main propagation method for azaleas is cuttings. Around Grain in Ear, select new branches 5 cm to 10 cm long, cut them off at the branching point, strip off the lower leaves, keep 3 to 4 top leaves, insert 1/3 of the branch into the soil, spray enough water, and cover with plastic film. Strengthen management as usual, and transplant after one year.

How to grow azaleas: the growing methods and points for attention for azaleas

The azalea is a rather lovable flower, so do you know how to grow azaleas? Today I will tell everyone about the growing methods and points for attention for azaleas.

Growing methods for azaleas:

1. Environmental conditions: it is best to have both indoor and outdoor environments for cultivating azaleas. The indoor environment is used in winter. The outdoor site is used in summer and autumn, and muddy ground is best; cement ground should be avoided. The site should be spacious, ventilated and shaded, and a shade shed should be built on top, covered with reed blinds or using the shelter of natural tree shade; a light transmittance of about 30% is suitable, and exposure to the afternoon sun must be avoided.

2. Potting soil requirements: azaleas like loose, highly permeable, well-drained acidic soil rich in humus, with a pH of 5.0-6.0; if clay or alkaline soil is used, hardly one in a hundred will survive. In particular, summer azaleas and Western azaleas must have mountain soil. The mountain soil also needs to be improved, and at present three kinds of prepared culture soil are commonly used.

3. Flower pot selection: for the flower pots used to cultivate azaleas, generally two kinds are chosen, clay pots and purple clay pots. Clay pots have good ventilation and water permeability, and production units all use this kind of pot for cultivation. For well-formed azaleas, especially azaleas that have been shaped, in order to be displayed indoors and outdoors, they are generally planted in beautiful, antique purple clay pots; purple clay pots are fine in texture, rich in color and beautiful in shape, and can double the ornamental value.

4. Improving water quality: for watering azaleas it is best to use rainwater, and next river water or pond water. If tap water is used, it is best to store the water for 1-2 days to let the chlorine volatilize before use. When using it, add 0.2% ferrous sulfate, and water once every 7-10 days during the growing season; using it regularly ensures the soil is acidic.

5. Fertilizer and water management: azaleas like shade and moisture and should not be too dry. During the flowering period they especially need more water. In winter azaleas have already entered the dormant period and do not need much water, so generally water once every 4-5 days, preferably around midday on a clear, warm day;

6. Outdoor shading: before being moved out of the room and before flowering, they should be given more sunlight; during the flowering period, short periods of shading should be carried out at midday, with a light transmittance of 60%.

7. Shaping and pruning: azaleas grow relatively slowly, and are generally allowed to grow naturally, with shaping done only after flowering, cutting off leggy branches, diseased and weak branches, deformed branches and damaged branches.

8. Disease and pest control: for the azalea lace bug (also known as the azalea lace bug, Stephanitis) during the damage period, spray a 1500-fold dilution of 40% dimethoate, once every 7 days, for 3 consecutive times. The control method for the bud-rolling leaf roller mainly relies on manual capture and killing, and the larvae or pupae can also be sprayed and killed with a 2000-fold dilution of 40% dimethoate emulsifiable concentrate or a 1500-fold dilution of dichlorvos.

How to grow azaleas: a complete guide to growing methods for azaleas

The azalea is also called mountain pomegranate and yingshanhong, and is an evergreen plant. The cuckoo cries blood that dyes the flowers all over the mountain red, hence the name azalea. The colors of azaleas are mainly deep red and pale red, with purple and white also fairly common. When azaleas bloom the whole mountain is very bright and beautiful, and they are called the Xi Shi among flowers. How is it better to grow azaleas? Below, take a look at the complete guide to growing methods for azaleas.

1. How to grow azaleas——SoilGrowing azaleas in pots is a commonly used method for growing azaleas at home. The soil mix for azaleas needs to focus on looseness and air permeability, so soil with strong air permeability and drainage capacity is best. At the same time azaleas like light fertilizer, so it is suitable to use acidic soil plus some humus material.

2. How to grow azaleas——LightDuring growth, azaleas' demand for sunlight is long-day, needing at least six hours of sunlight exposure for half the day, but avoiding being out in the blazing sun all day. During the flowering season azaleas must be given shading treatment; using a special shade cloth for shading is more suitable, and azaleas are not suited to blazing sun during the flowering stage.

3. How to grow azaleas——WateringThe roots of azaleas are fine, so their water-absorbing capacity is not very strong. Therefore azaleas should be watered frequently to ensure a moist soil environment. Except during the winter dormant period, azaleas should be watered appropriately so that the flowers develop better.
