If the basin is used, the tile basin is more suitable and the ventilation effect is better. Because the Rhododendron root system is shallow and the growth is slow, the smaller basin can be selected, so that the water will not be wasted, and it is more conducive to growth. Basin soil aspect should adopt the texture is more loose, drainage good acid soil.
The root of Rhododendron is very thin and its absorptive capacity is poor, and the water can only reach the flower body through the absorption of the root, so watering Rhododendron is a technical work. If it is watered more, it is easy to rot the root, and if it is watered less, it will dry the leaves.
Generally speaking, we only need to keep the basin soil moist in early spring. At the end of spring and the beginning of summer, when it is ready to bloom, the water demand will increase greatly, so water it a little more.
In summer, the temperature is too high. In addition to watering, spray some water on the plants. In autumn, when the weather turns cold, it is necessary to control the water moderately and let the basin soil dry slightly. In winter, when it goes into dormancy, it will reduce watering.
Rhododendron breeding process to ensure its full light at any time, because the full light can bloom well, hot summer can not take out the sun, should strengthen the work of shielding, to prevent from being damaged by the sun, in addition, in the flower season should also properly do a good job of protection, can use a light screen for protection, flowering period can not be exposed to the sun
Appropriate fertilization can make Rhododendron culture grow more robust and rapid, and most indoor flower culture, Rhododendron fertilization principle is also thin fertilizer, that is, a little less at a time, you can apply several times.
When the old leaves turn green, bloom and bloom, apply fertilizer two or three times properly. During the hot weather, do not apply fertilizer. The cultivation and fertilization of Rhododendron can use fishy water, rapeseed cake and other materials, all of which can be used only when they are rotted. If any diseased branch is found, it should be cut off in time to prevent affecting the healthy growth of other branches.
The most suitable temperature for Rhododendron growth is 15-25 ℃, in spring or autumn, try to let it grow in this temperature range. In summer, when the temperature is relatively high, we should pay attention to temperature control. The maximum temperature should not exceed 32 ℃. When the temperature is relatively low in winter, we should move it to the house in time and keep the temperature above 5 ℃.
Pruning. Rhododendron grows very fast and easily grows very dense, which will lead to many internal branches and leaves can not see light and can not grow healthily. So we should trim it in time, not only to make it more beautiful, but also to make it more healthy.
Change the basin. The growth of Rhododendron needs to consume the nutrients in the soil. After a year or two of cultivation, the nutrients in the soil will be absorbed by it. At this time to give it a new nutrient rich soil, it can continue to grow healthily
A lot of flower friends say that azalea is hard to raise. It's easier to die in summer. Then I dare not touch azalea any more. I've raised azalea before and I can't understand it. Now I finally understand it. In fact, as long as I remember 3 o'clock, I can raise it well: don't sun it at noon, try to get wet and water it in time
