How to plant azaleas, how to grow azaleas

Rhododendron cultivation requires the use of well-drained, loose, weakly acidic soil. Phosphorus-based liquid fertilizer before flowering, stop fertilizing during flowering, and apply nitrogen fertilizer after flowering. Watering once every two or three days in spring and autumn, once a day in summer, and stop watering in winter.

In winter, the room temperature should be kept at about 10, and the outdoor temperature can be cultivated after April.

1. Soil. Rhododendron likes loose and well-drained weak acidic soil, you can use humus soil, peat soil mixed with self-made culture soil, potting can add an appropriate amount of bone meal, increase minerals.

2. Fertilization. The absorption capacity of rhododendron is weaker than that of other plants, so it is necessary to adhere to the principle of 'thin fertilizer and frequent application' when fertilizing, and the fertilizer applied in different growth periods is also different. From February to April before flowering, phosphorus-based liquid fertilizer can promote larger and brighter flowering. Stop fertilizing during flowering, otherwise it will lead to early flower fall; Nitrogen fertilizer is applied about 10 days after flowering to promote the growth of new branches.

After late July, potassium dihydrogen phosphate is applied every 10-15 days. If it is dormant in winter, it does not need to be fertilized.

3. Watering. Rhododendron requires the soil to be moist but not wet, so watering should not be too frequent, otherwise it will cause root rot. In spring and autumn, it is watered once every two or three days, and in summer it can be watered every day, and in winter it is time to reduce the amount of watering.

Note that the water should not be too cold when watering, otherwise it will affect its growth, and the leaves can be cleaned and sprayed one by one when watering.

Fourth, temperature. The azaleas are supposed to be moved into the city in early October until mid to late April. In winter, the room temperature is about 10 is the most suitable, pay attention to ventilation. After April, the sun is mild, so it's no problem to be outside.

Rhododendron can be planted in pots or in shade, except for the West Juan, which is potted in all rows.

The cultivation of Cuckoo requires two environments: indoor and outdoor: indoor is used for winter cold, and the temperature should not be lower than -2--3. In order to survive the hot summer, the Jiangnan area is kept outdoors from mid-April to early November, requiring natural shade from deciduous trees, or artificial canopy to create a semi-shady and cool growth environment.

In production, good permeability and low cost tile pots are used. Rhododendron has a shallow root system and slow expansion, so try to use small pots for cultivation to avoid uncontrolled watering and unfavorable growth. About the age of the plant and the size of the pot.

Generally, 1-2 years old with 3-inch pots; 3-4 years old with 4-inch pots; 5-7 years old with 5-inch pots; 8-10 years old with 6-inch pots; 11-15 years old with 7-8 inch pots. It is commonly used in black mountain soil cultivation, with black color and light quality. When you use it, spread it out and expose it to the sun for a few days to pick out the debris.

In addition, peat soil, Huangshan soil, humus leaves, pine needle soil, and even mixed soil with cinder, sawdust, etc., as long as the pH is in between, permeable and drained, rich in humus, can be used. Generally, when you leave the room in the spring or enter the room in the fall, you will put on the pot or change the pot. After potting, place it in the shade for a few days and then move it to its proper location.

The seedling stage is repotted once every 2-3 years. After 10 years, it can be repotted once in 3-5 years.

Rhododendron azalea.

Rhododendron other can be referred to.

How to plant newly bought azaleas? Rhododendron buying and planting tips, it is not difficult to plant azaleas.

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. <>

Soil treatment. Rhododendron is mainly potted plant, which is conducive to meeting the ecological conditions of different varieties. Cultivation soil requirements are mainly acidic soil, pH must be below 6 as well, no matter what kind of soil is used, before cultivation, soil disinfection is required, full decomposition, fermentation, high and low temperature alternate treatment, one year later, can be used.

Transplant in pots. There is no water hole in the pot, cover it with several tiles, fill a layer of coarse-grained soil, then fill in the fine soil every other year, plant the seedlings in the middle of the pot to stretch the roots, add soil to the pot to the rhizome, compact, and level the soil surface with the pot. Spraying the new high-lipid film can effectively prevent the water on the ground from evaporating, the moisture of the seedling body from transpiring, isolate pests and diseases, shorten the seedling period, quickly adapt to the new environment, and grow healthily.

Repotting period. Changing the pot is because after the plant grows up, it can not meet the ecological conditions, so it is necessary to change the new culture soil, take the plant out of the old pot and drop some shrinkage soil, so that the surrounding roots are comfortable, and cut off the diseased roots, the operation is the same as above. Generally, it is changed every 2-3 years.

Large plants are 3-5 years old, and extra-large plants can not be replaced.

Watering and fertilizing. Rhododendron watering is best with rainwater, river water, lake water, water from ponds, and fish farming water. Depending on the growing period, choose the amount of watering.

Fertilization is based on basal fertilizer, long-acting hooves, nail tablets, bone meal, cake fertilizer, manure, etc., which are mixed with the soil when potting or repotting. Top dressing with human manure and chemical fertilizer, fast-acting fertilizer. Different fertilizers should be applied to rhododendrons at different stages of growth.

Fertilization is stopped during the winter dormant period. Spray new high-fat film to protect fertilizer and moisture.

Trim and peel buds. In order to maintain the beauty of the rhododendron tree, it is necessary to prune weak branches, diseased branches, dead branches, cross branches, overlapping branches, overly dense branches, and long branches from the base every year. When the rhododendron tree grows to the desired height, the apical buds are removed to control the height and germinate side branches.

After topping, many side branches grow and are in the shape of rotations. When the side branches grow to a certain height, they are topped. Germinates secondary lateral branches.

Spraying flowers at the bud stage can promote strong flower buds, hypertrophic petals, bright flower color, rich floral fragrance and prolonged flowering period.

1. To cultivate and breed rhododendrons, we must first choose the right cultivation soil. Loose, smooth drainage, good aeration, acidic soil, rich humus, and sufficient base fertilizer are the basic conditions for breeding rhododendrons. Acidic soils allow rhododendrons to grow vigorously, but in alkaline soils, they quickly wither and wither.

2. Watering the azaleas is also a very important job. The root system of rhododendron is relatively weak, and too dry or too wet is not good for plant growth, so special attention should be paid to controlling the amount of water when cultivating rhododendrons. The lack of water during the leaf-growing period will cause the rhododendrons to turn yellow in color, curl the branches and leaves, and if they are severely dry, they will die.

The lack of water during flowering will make the petals squirt, the flowers droop, the color is not fresh and the cherry blossoms are late, and even the pure flowers will wither and wither. Therefore, watering rhododendrons must be done according to the weather, air humidity and soil moisture content. The time of watering is early in the morning and evening, and it is not advisable to water at noon, especially in the hot summer.

When watering, it should be noted that it is not dry or watered, and it must be watered thoroughly, and half of the water cannot be watered.

3. Rhododendron is more fertilizing, and the best way to breed rhododendron is to use humus cooked cake fertilizer, fish meal, broad beans or milk vetch. After humus, it is mixed with weakly acidic water for irrigation, and animal manure should not be used. After moving out of the room in spring until the flower buds spit out flowers, apply thin fertilizer every ten days, with a concentration of 12%-18%, for one month to promote the old leaves of rhododendrons to turn green and new roots to grow and develop.

After bringing the rhododendron to the flowers, in order to promote the growth of branches and leaves, thin cake fertilizer water or thin alum fertilizer water is applied every half month from mid-May to early July.

4. Rhododendron hydroponics should be very careful, the root system of rhododendron is very slender, so the hydroponic substrate is required to be loose and conducive to ventilation and drainage. Use 1 part of vermiculite, 1 part of pearl sand, 1 part of river sand, and 1 part of cinder to mix in proportion. After mixing, sterilize with carbendazim, mix evenly into the matrix and cover with plastic film for 1 day.

Then rinse it with water several times and dry it, mix it with agricultural compound fertilizer, and then cover it with plastic film for a month, and then use it in a pot. Hydroponic Du Xiaosong is also strict for the preparation of nutrient solution. During the growing season, thin fertilizer is applied frequently.

Take a look at the agricultural support network, there is an introduction to this.
