How to manage rhododendrons in the spring and how to manage them after the rhododendron flowering pe

The master will teach you: the maintenance method of azalea in spring!

After the rhododendron period, it is necessary to do a good job of pruning, light, watering, fertilization and maintenance management measures. Cut off the residual flowers and the receptacles, and maintain 7-9 hours of sunlight every day to promote the growth of branches and leaves. Every time you water, you should ensure that the potting soil is slightly moist to avoid stagnant water.

After flowering, nitrogen-based fertilizer is applied every 10 days.

After the rhododendron flowering period, pruning can be carried out. Prune off the broken flowers of the azaleas, pay attention to the pruning of the residual flowers, do not cut off the entire flowering branches, and cut off the residual flowers with the receptacles. There are also some diseased branches, long branches, and deformed branches that are cut off one by one.

After the rhododendron blooms, it is important to keep it in good light. It can maintain 7-9 hours of sunlight per day, which is conducive to photosynthesis and promotes the growth of branches and leaves. When the light is strong, move to a cooler and ventilated position to avoid strong direct sunlight.

After the rhododendron flowering period, it is necessary to do a good job of reasonable watering, because azaleas like to grow in a relatively humid environment, so every time you water to ensure that the potting soil is slightly moist. However, it should be noted that the root system is relatively thin, and the amount of water must be appropriate, so as to avoid stagnant water.

After the rhododendron flowering period, it is necessary to apply fertilizer regularly. After the flowering, chase 1 nitrogen-based fertilizer every 10 days or so, and enter the growth period every 10 15 days should be followed by 1 time of phosphorus-based liquid fertilizer, and fertilizer is not needed during the winter dormant period, and top dressing should be stopped.

1. Temperature control: the most raised in the rhododendron is the east cuckoo and the west cuckoo, the east cuckoo is not afraid of freezing, the cold resistance is excellent, in addition to the northeast can be outdoor wintering, the west cuckoo is more afraid of cold, winter to be placed in the indoor heating room maintenance.

2. Bask in the sun: Rhododendron is afraid of the scorching sun, but it cannot lack light during maintenance, otherwise it will affect the differentiation of rhododendron buds, so in addition to the family or summer exposure needs to be shielded, spring and autumn can be placed on the east balcony for maintenance, and in winter on the south balcony all day long.

3. Proper watering: Rhododendron likes water and is afraid of waterlogging, it is best to weigh the weight of the pot soil, feel obviously lighter and watered, water until there is water flowing out of the bottom of the pot, rhododendron likes sour, the temperature of the heating room is high, and you can also water the peel of the flower once a month.

4. More ventilation: indoor heating in winter, dry air, coupled with the maintenance environment is not ventilated, the rhododendron loves to drop the leaves, in winter, take advantage of the high temperature at noon to open the window for ventilation, and move the rhododendron away from the window when ventilating.

5. Avoid fertilization: The temperature is low in winter, or the rhododendron is in the flowering period, it can not be fertilized, you can wait for the next spring after the rhododendron fails, take 6g of bean cake and bone meal, divide it into four parts and bury it on the edge of the pot, and water it thoroughly.

6. Light pruning of residual flowers: After the rhododendron is defeated, do not re-prune, just pinch off the residual flowers, gently prune the long branches, and wait for the arrival of the trillion branches in the autumn of the year to sprout buds, and then bloom a stubble of flowers.

Rhododendron flowering management skills: rhododendron likes cool and humid climate, requires rich humus, loose, moist, pH value in the acidic soil, has certain requirements for light, not resistant to exposure, should be maintained under semi-shaded conditions, flower bud period refers to the rhododendron from the beginning of the bud to most of the flowers open this time, generally 90 to 120 days of Chongkai, the length of this period has a lot to do with humidity and maintenance, to make the flowers bloom well, open long, we must pay attention to bud management, the main points are as follows:

1. Light, rhododendrons must be maintained under semi-shaded conditions, and the light should be appropriately added at the early stage of the buds, and the flower buds should be weakened during the expansion period;

2. Temperature, the morning and evening of the flowering period have the greatest relationship with the temperature, the temperature is high and the flowering orange is late, so the temperature control can prolong the flowering period, and the appropriate temperature after flowering is 10 degrees Celsius to 15 degrees Celsius during the day and 5 degrees Celsius to 10 degrees Celsius at night;

3. Water, because rhododendrons are shallow root systems and slender root groups, they are afraid of drought and waterlogging, improper watering, and the light will fall leaves, and the heavy will die;

4. Pest control, azaleas like to grow in a wet environment, so there are more opportunities for pest and disease infection, especially Western cuckoos.

Rhododendron flowers usually bloom in April and May, so start paying attention around April! The flowering period of azaleas lasts for about 40 days, and the temperature can also be lowered to delay the flowering time if conditions permit.

Avoid rain During the flowering period of azaleas, rain should be avoided, especially if it is maintained outdoors, it should be moved indoors or sheltered from rain. Rain during the flowering period of azaleas can easily cause the color of the flowers to decrease and affect the ornamentation.

Reducing light and increasing humidity At the beginning of flowering, the azaleas should be moved to a place with sufficient scattered light for care, and cannot be placed directly in the sun, otherwise it will cause the flower color to fade and even the petals to be burned. In addition, the relative humidity of the air around the rhododendron should be maintained, and water can be sprinkled on the ground frequently, but do not splash the water on the branches or flowers carelessly when sprinkling.

Move indoors When potted azaleas are not in bloom, most families will choose to put them on the terrace to maintain, and when they bloom, they will want to move indoors to enjoy the flowers, but the time of entering the house is particular. Usually choose the plant 1 3 flowers have bloomed when the plant is already in bloom, move the plant to the indoor place with sufficient light, move it indoors too early, the azalea will affect the flowering due to insufficient light, resulting in a dull flower color.

After moving indoors, ventilate frequently, and at night the plants can be moved outside (patio) to receive night dew.

Moist potting soil During flowering, the dryness and wetness of the potting soil should be kept relatively stable, not too dry, not too wet, otherwise it will affect the quality of flowering and shorten the flowering period.

Removing flowers When all the azalea flowers have opened, and even some have begun to wither, all the flowers should be removed in time to ensure the nutrients for the normal growth of the plant. At this time, don't feel unbearable, the most gorgeous time of the flowers has passed, the flowers are still left on the branches, just consuming nutrients, and the ornamental value is not large.

Move outdoors After removing the flowers, move the plants outdoors and spray Tobuzin's solution to prevent insects. Fertilizer should be applied once after a week, and a mixture of nitrogen fertilizer and ferrous sulfate can be selected. Then normal management is fine. By raising flowers in this way, the plants can be prevented from aging prematurely, and they can bloom normally next year.

1. Environment: When cultivating rhododendrons, they need to be placed in an environment with a temperature of 12-25 degrees to avoid poor plant growth.

2. Pruning: After the rhododendron blooms, it is necessary to cut off the long branches of jujubes, the weak branches of diseased oranges and the residual flowers to avoid the loss of excess nutrients.

3. Water and fertilizer: Rhododendron peanuts need to be watered once a week for a long time, and thin fertilizer should be applied once a month.

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 spend 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 ring Zen vertical cavity 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.

Spring is the middle and late flowering period of rhododendrons, and it needs to be managed during flowering. The specific method varies from variety to variety, but for newly opened varieties we need to give them stable light, the right temperature, the right amount of moisture, and stop fertilizing and control pests and diseases.

For the rhododendron varieties after the flowering period, it is necessary to cut off the residual flowers in time after it blooms and fails, and properly top dressing to promote the germination of new shoots, and at the same time control the development direction and length of new shoots through pruning, topping, etc., so as to make the plant as plump as possible.

Rhododendron grows more slowly, so it can be formed from the orange light and close, and the natural growth shape is more beautiful, and it does not need too much trouble pruning. However, the germination of new shoots in the spring will make the nutrient distribution of the whole plant uneven, and individual buds will grow very fast, especially vigorous, and especially vigorous. At this time, the bud needs to be removed from the base to prevent it from growing too strong and causing the plant to be disordered.

Maintain the rhododendron indoors and do not move it outdoors to prevent it from catching a cold. In northern areas, it is necessary to wait until the room temperature has stabilized above 15 before leaving the room, so that it will not be affected by the cold spring or the drastic change.

In the spring, it is also necessary to prevent the occurrence of aphids. The relatively arid environment in spring is more suitable for the growth and reproduction of aphids, and aphids can be lured by hanging yellow boards at home to achieve the purpose of pest control.
