How to raise azaleas well How can I raise azaleas?

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.

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.
