How to raise azaleas? Can you raise them well?

Rhododendron is a famous flower plant, which is planted all over the world. In China, it is the provincial flower and city flower of many provinces and cities, and it is rated as the sixth among the top ten flowers in China. Rhododendrons bloom in spring and are sought after by the public. Some rhododendrons have been cultivated into modeling bonsai, which can not only appreciate flowers, but also view leaves and shapes, thus improving the ornamental value. So, how to cultivate azaleas at home?

liquid manure

1, potted azaleas, every time you water them, you have to see the water flowing out of the permeable hole at the bottom of the flowerpot, which is considered to be thoroughly watered. As for the problem of stagnant water, give a reference. For example, if the water is about 10 in the morning, at night, if the basin soil is already in a state of no water, it will be fine, and there is no need to consider the problem of water accumulation. You can spray water mist on the leaves at night, which is beneficial to the germination of new buds.

2. Rhododendron love the water, if it is often dry, it may not die of drought, but it will certainly not grow well, let alone bloom well. Therefore, when watering, we must master the principle of seeing dry and seeing wet, especially in the spring growth and flowering season, and we must ensure sufficient water.

3. Potted azaleas need not be fertilized or not. For example, azaleas planted during 1-3 months should be fertilized at least after May, preferably not during flowering. It is necessary to apply more phosphorus and potassium fertilizer, but also to apply thin fertilizer frequently, preferably liquid fertilizer. Soak the decomposed organic fertilizer in water, mix the fertilizer solution with water and water the flowers.

When you plant azaleas, you will find that the roots of azaleas are very small and fragile. Drought, stagnant water and heavy fertilizer will all cause fatal damage to it. Frequent drought will make its capillary roots die and its branches dry and shrink, which is the reason for poor maintenance. However, if there is too much water, the tiny capillary roots will be soaked in accumulated water, which is easy to rot. Not to mention fat, it is very delicate in general.

Lighting ventilation

1. In winter, in addition to overwintering indoors, it is best to put it on the balcony in the southeast, or directly cultivate it outdoors, which can not only have good lighting, but also good ventilation and reduce the occurrence of diseases. However, in flowering period, it is necessary to properly shade and maintain the light transmittance of 40%-60%.

In summer, we should pay attention to avoid strong light. Too strong light will slow down the growth of Rhododendron, the branches and leaves will turn yellow and the roots will age. In this environment, we should also be prepared to spray water for moisturizing, and spray water separately in the morning and evening to ensure the normal growth of azaleas.

3. potted azaleas should be moved indoors for maintenance in winter. Generally, rhododendrons can be moved indoors in the first ten days of 10, and the room temperature can be kept around 10℃. Too low temperature will lead to defoliation, while too high temperature will make rhododendron sprout prematurely, consume nutrients and affect the flowering in the coming year. Usually, I open the window at noon on a sunny day to get some air.

Pruning modeling

1. A cultivated potted rhododendron should not only bloom beautifully, but also have a beautiful shape to increase its ornamental value. Pruning and binding can be done before germination in winter or spring. It is best before the roots germinate, but they haven't germinated yet. At this time, the sap begins to flow frequently, and the branches become soft accordingly, which is a good time to do it. But be careful when you do it, so as not to cause broken branches.

2. Pruning is also very important for azaleas. The most important pruning is after flowering. As we all know, azaleas are good at flowering. When they enter the flowering period, new flowers will bloom basically every day. At best, they are basically full of flowers and have no leaves. Although this is beautiful, it is overdrawing the vitality of azaleas. The best way is that in the second half of each flowering period, through observation, it is found that there are still about one-third of the buds, which need pruning. It is very important to cut off all the flowers and buds of the tree. You can ensure that the tree will not be damaged, and you can see beautiful azaleas full of trees next year.

control of insect

1, domestic cultivation of flowers generally does not cause pests and diseases, but if the cultivation environment is not ventilated and the trees grow badly, it will cause pests and diseases, and so will azaleas. Every March, when pests and diseases start to wreak havoc, we should prepare preventive chemicals for spraying prevention and control. Spraying for half a month 1 time, 2-3 times can effectively prevent the occurrence of pests and diseases.

2. If pests and diseases have occurred, physical removal and chemical spraying should be carried out in time. Remove diseased leaves in time, catch pests, and then spray. When spraying, avoid noon, spray all hidden places such as the reverse side and side of the blade, and spray around. Especially other flowers or trees, spray all cultivated plants once, not only those infected with pests and diseases.

Rhododendron potted plants, or Rhododendron bonsai, are deeply loved by the public and have a high penetration rate. Even now, rhododendrons can be seen in urban greening, streets, scenic belts, small parks, rest places and other places. You can also see some old piles, which are really beautiful. Don't wait, raise a pot quickly.
