Conservation of rhododendron

Beautiful plant, we need to make some efforts to love it, so is the rhododendron. What do we need to pay attention to in its cultivation? let's find out together.

1. It likes a cool environment. The area south of the Yellow River can be kept in a shady and ventilated place outside from mid-April to early November, with strong sunshine and high temperature in summer, which must be placed in a shade shed or tree shade to create a cool growth environment of semi-overcast and rain; in winter, it is appropriate to put it in a greenhouse or indoor maintenance, keeping the temperature above 5 ℃.

2. Watering needs attention. No dry, no watering, watering thoroughly, strictly prevent waist water, this is the principle of rhododendron watering. Because azaleas like acidity, it is best to acidify the water with black alum before use. When watering, Rain Water must be used for watering. If tap water is used, tap water must be used after drying, because the roots of azaleas are relatively weak, and they are both afraid of waterlogging and are not resistant to drought, so special attention should be paid to controlling the amount of water. Under normal circumstances, spring and autumn can be watered every 2-3 days. It grows vigorously in summer and consumes a lot of water, so it needs to be watered 1-2 times a day. Watering time should be 8-10:00 and 4-6 pm, hot summer is not suitable for watering at noon, after the root is stimulated by cold water, flowers will be hurt.

3. Requirements of fertilization and basin soil. Azaleas like acid soils that are loose, permeable, well drained and contain humus. Generally, rotten cake fertilizer and fish meal are watered with water after decaying. After leaving the room, before the flower buds spit out flowers, thin fertilizer is applied every 10 days, with a concentration of 15%. A total of 2 mi is applied 3 times to promote the old leaves to turn green and sprout new roots. After the flowers fade, in order to promote the growth of branches and leaves, fertilization was applied 6 times from mid-May to early July. If it rains continuously, dry fertilizer can be applied. Before entering the house, before the growth of azaleas is about to stop, fertilizers should be applied for 1 / 2 times.

As long as pay more attention to the soil conditions of rhododendron, water and fertilizer management, strengthen the prevention and control of diseases and insect pests, and pruning and shaping, we can cultivate excellent rhododendron bonsai. Friends should cultivate it attentively.

The cultivation method of azaleas how to preserve azaleas?

Rhododendron is one of the top ten famous flowers in China. Among the ornamental flowers, rhododendron can be called beautiful flowers, beautiful leaves, suitable for soil culture and potted plants, and is the most widely used ornamental flower. There are many categories of azaleas. Most varieties have low plants and natural shape, while a few varieties are tall and majestic with whirling branches and leaves. There are many colors, depending on the variety, there are lilac, sprinkle gold, some have two colors, some flowers have aroma. The capsule is dark brown when mature, and the seeds are dark yellow and fine. According to the different florescence, it can be divided into four categories: spring cuckoo, summer cuckoo, spring and summer cuckoo and western rhododendron. So how to raise cuckoos? Today, the editor will take you to learn how to grow cuckoos.

1. Soil

In general, the cultivation methods of plants and flowers are inseparable from the good soil environment, and the soil environment is more important for the cultivation methods of azaleas. There are many methods for the cultivation of rhododendron culture soil, due to different varieties, but the most important thing is to have the following conditions: loose, unobstructed drainage, good ventilation, acidic soil, rich humus and sufficient base fertilizer.

Second, watering

As we all know, watering is a very important work, and the skill of watering is very important for the cultivation of azaleas. Because of the thin roots of azaleas, we should pay attention to not too much and certainly not too little when watering, as long as it is appropriate. And the watering time is best in the morning and evening, which is good for azaleas to absorb water.

III. Fertilization

Azalea is a very atmospheric flower, she does not need too much fertilizer to grow, so be careful not to fertilize too much, too much fertilizer will make it difficult for azaleas to absorb and die, proper fertilization can make azaleas grow well and bloom beautifully.

Fourth, sunshine

Rhododendron culture method is also a very important and indispensable is the absorption of sunlight, for plants and flowers, it is necessary to promote photosynthesis. Therefore, the growth of azaleas is also inseparable from the sun, but can not be exposed to the sun all day, suitable sunshine can make azaleas bloom more beautiful and moving.

V. matters needing attention

1. The roots of azaleas are as thin as hair, and there are few thick taproots. They are afraid of both dry and wet, especially heavy fertilizer. If too much watering, the root is soaked in water, too dry, branches and leaves atrophy, leaf petal fall off, a great threat to the plant, as for watering heavy fertilizer, it will be life-threatening.

2. after the flower fade, the residual flowers must be cut off to avoid fruiting and wasting nutrition. after the new branches germinate, they should be thinned properly and stay according to the growth of the plant.

3. Rhododendron is most suitable to be planted in muddy basin, because the mud basin absorbs water and breathes air, which is beneficial to the growth and development of roots and luxuriant branches and leaves.

4. Potted azaleas should be placed on the southeast balcony and should be ventilated and moved as little as possible. If it is not ventilated, it is easy to suffer from black spot disease and a large number of fallen leaves.

5. Cuckoos should also have moderate requirements for light, and avoid direct light in summer. Fertilization should grasp the application of thin fertilizer frequently, can be light but not strong, and apply organic compound fertilizer on the basin soil once a month. Potassium dihydrogen phosphate was sprayed every 10 days for extra-root fertilization. Timely watering, you can also put edible vinegar in the water to increase acidity.

6. timely thinning of buds and leaves, removing part of the buds and leaves that have grown too much and too dense, so that the air is well ventilated and nutrients are concentrated on the buds. After the formation of buds, it is necessary to increase nutrition and apply more phosphorus and potassium fertilizer, otherwise the buds will be transformed into leaf buds.

7. The main reasons for azaleas falling leaves and not blooming are: too much direct light in summer, frostbite, too much watering, too thick fertilization, too long indoor time, poor air circulation or dark and humid places, acid rain, and so on. so these situations should be avoided in the process of maintenance.

8. Turning the basin and changing the soil do not need to be carried out every year, usually once every 2 to 3 years, with as little damage to the roots as possible. The time should be after the blossom fade or in autumn, and topirazine should be sprayed at the same time to prevent diseases.

9. The pests of azaleas are mainly red spiders and aphids, which can be sprayed with permethrin, and the effect is better, such as not dying after three days, spray again. The disease is mainly black spot, which is caused by muggy environment and lack of light. Measures can be taken to promote air circulation on the one hand and spray Bordeaux solution and carbendazim on the other.

10. The propagation method of rhododendron is mainly cutting. Before and after Grain in Beard, select new branches, 5 cm to 10 cm long, cut off at the bifurcation point, peel off the lower leaves, leave 3 to 4 top leaves, insert the 1x3 of the branches into the soil, spray enough water, and cover with plastic film. It is necessary to strengthen the management at ordinary times and transplant a year later.

The above is the maintenance method of rhododendron introduced by the succulent garden. I hope it can be helpful to you. Welcome to continue to pay attention to the succulent garden and learn more about the conservation of azaleas!

Rhododendron culture rhododendron belongs to neutral flowers, like warm, semi-shady, cool, ventilated, moist environment. Require loose, fertile, humus-rich acidic (loess) soil, pH between 5.5 and 6.5, do not use alkaline or clayey soil. The suitable growth temperature is 12 ℃ to 25 ℃, sunshade in summer, freezing and warmth in winter, it is best to move indoors, especially the delicate rhododendron, such as rhododendron, should pay more attention to maintenance.
