Rhododendron bonsai making
1, pot selection: Rhododendron generally adopts slightly deep oval, rectangular or round pots, and the texture can be purple sand pottery or glazed pottery. The color of the basin is darker, in contrast to the design and color, it is best not to have flowers on it. In case of rhododendron cliff, you can use a deep thousand-tube basin; Rhododendron lugens can be used in slightly shallow oval pots.
2. Soil: Rhododendron should choose fertile and loose humus soil or mountain soil in pine forest. Potted plants are often dry and frozen pond soil or paddy soil mixed with appropriate amount of sand.
3. Planting: You can plant potted plants in early spring or after flowering. If Shan Ye stumps are excavated, they need to be planted with native soil, because there are mycorrhiza in the roots. When planting, the straight roots can be cut short, and chicken manure or bean cake can be put at the bottom of the basin as the base fertilizer. Branches and leaves should also be trimmed properly.

1. processing: the processing of rhododendron seedlings can be started in 3 ~ 4 years. Rhododendron branches are brittle and not suitable for excessive climbing. Only when the main branches are properly shaped, it is better to climb with brown silk. Other branches are pruned. When pruning, pay attention to adjust the strong and weak branches, re-cut the strong branches and lightly cut the weak branches. Climbing is generally carried out in spring, and the branches are soft and easy to climb during the growing period.
2. Tree shape: The tree shape of rhododendron is usually straight, curved and inclined, and can also be processed into exposed root shape, cliff shape, attached stone shape and connected root shape. Through artistic modeling, beautiful bonsai with flowers, stems, roots and shapes can be achieved.
Propagation method of rhododendron
Rhododendron can be propagated by sowing, cutting, grafting and tillering. Generally, cutting is the main method, with simple procedures and fast flowering. The cutting time is better in rainy season. Cuttings adopt branches of the same year. After the new buds are formed, the cuttings are cut at the base, which is the easiest to survive. If old branches are used as cuttings, it is difficult to take root. Rhododendron cutting, seedbed soil should use acidic mountain mud or sun-dried, weathered pond soil and humus soil, such as cutting mountain mud in a wooden frame.
In order to ensure the survival of precious rhododendron varieties, the incision can be wrapped in moss into balls and inserted into the soil about 3 ~ 4 cm deep, which is easy to take root. After planting, you should set up a shed for shade and spray water several times a day to keep the seedbed moist. After about 2 ~ 3 weeks, the incision can gradually heal and take root, and the light time can be increased after the cuttings take root. After about 2 months, pancake fertilizer can be applied to promote its growth. Potted seeds can be planted in the following spring.
Seeding and reproduction can be done with wooden frames or clay pots. The bottom of the pot should be padded with vermiculite or leaves to facilitate drainage. Put mountain mud or humus soil into the basin, add appropriate amount of sand, flush with the mouth of the basin (slightly shallower than the mouth of the basin), and then sieve a layer of fine soil. Seeds should be sown on it, not covered with soil, covered with glass, and preferably lined with newspapers to keep it moist. It will germinate and be unearthed in about 3-4 weeks. At this time, the glass cover should be removed, illuminated, and properly sprayed with water. When the seedlings grow to 3-4 leaves, they should be planted separately.
What should I do if the azalea leaves?
1, the environment is not suitable for defoliation
Most azaleas sold in the market are cultivated in greenhouses. After buying it back, it can't adapt to the natural environment of the family, and often leaves and even dies. Rhododendrons cultivated in different places will have the same problem.
Solution: Newly bought azaleas should keep the air humidity as much as possible, properly shade, keep the basin soil moist, need air circulation but can't be blown directly by cold air, don't rush to change soil and fertilize, and try to make it pass the adaptation period safely. In winter, there is enough light, so indoor maintenance should be placed under the south-facing window as far as possible, and the ambient temperature should not be lower than 5 degrees. Don't change places at will, lest the temperature change dramatically. Don't put it in a dirty place.
2. Inappropriate defoliation of basin soil
The solution is to use acidic soil with good ventilation and rich humus, and the pH value is 5.5 to 6.5. Usually apply some alum fertilizer water properly, or add a little ferrous sulfate to the water. If alkaline soil is used, the leaves will turn yellow and fall off.
3. Fertile fallen leaves
Rhododendron doesn't like big fat. The most common deviation of planting Rhododendron at home is not lack of fertilizer, but excessive fertilization. Once raw fertilizer and thick fertilizer are used, scorched leaves will appear, causing deciduous leaves. The so-called fat damage.
The solution is to add an appropriate amount of slow-release fertilizer to the soil when changing pots (the surface of the fertilizer is coated with an organic film, and the fertilizer is slowly released to supply plant nutrition through the infiltration of the film), which is safe, clean, long-lasting, colorful and leafy. This fertilizer is often used in horticultural production, which is convenient and clean, and the rhododendrons planted are luxuriant in leaves and flowers. Once fertilizer damage is found in family planting, fertilization should be stopped immediately, and the fertilizer in the soil should be watered and washed. After watering, it should be moved to a ventilated place for maintenance, and some should be washed twice. After maintaining for about half a year, you can gradually return to normal growth.
4. Waterlogging leaves
Rhododendron root system is slender, such as poor soil permeability or frequent long-term watering, coupled with poor ventilation, root system damage and decay, leading to deciduous leaves.
Step 5 dry fallen leaves
If you are not careful, forget to water it, or don't water it thoroughly for a long time, leaves will also appear. Must pay attention? Completely pour? At ordinary times, water should be sprayed on the leaves and around them to improve the environmental humidity.
6. Sunshine and strong winds
Rhododendrons like sunshine, but they are afraid of the scorching sun. It likes ventilation, but it is afraid of strong winds. Putting it in the scorching sun in summer, and putting it in the tuyere in spring (especially early spring) and autumn will lead to a lot of fallen leaves.
The solution should pay attention to planting azaleas in sunny and sheltered places in the morning and evening.
7. Physiological defoliation
If the flowers are too dense, the old leaves will be removed without timely nutrition supply or new leaves. This is a normal state and can be solved by normal soil replacement and fertilization. Domestic rhododendrons generally bloom and germinate new leaves in April-June, and the old leaves will fall off. Pruning and shaping once after flowering, cutting off dense branches, cross branches, twigs, drooping branches, trailing branches and insect branches, is not only conducive to ventilation and light transmission, but also can promote strong branches and reduce deciduous leaves.
