Watering
Rhododendron likes a humid environment and is required not to be too dry. During the flowering period, it should be given sufficient water. In winter, its growth has actually become slow. At this time, there is little demand for water. Generally, it can be watered once every five days, preferably at noon on a sunny day. Secondly, if you breed indoors, you need to ensure a certain air humidity. You can spray water on plants and leaves, but it's best not to spray when flowering, otherwise the flowers will wither p>
Fertilization
In winter, there is no need to fertilize Rhododendron, but in January, it should be fertilized with base fertilizer, bean cake or bone meal p>
Temperature
In winter, temperature is also very important, but different varieties of Rhododendron have different requirements for temperature. Spring Rhododendron, summer Rhododendron and hairy Rhododendron are relatively cold resistant, and the temperature in winter should not be lower than 0 ℃. However, the West cuckoo requires the temperature to be above 2 ℃. If it is lower than this value, thermal insulation measures should be taken, otherwise the plant will be frostbitten p>
The breeding temperature of Rhododendron is 8 ℃ in winter. Air conditioning and heating should be used indoors p>
Pruning
The Rhododendron bonsai needs to be shaped by pruning and binding. In winter, it can also be moderately pruned, mainly by sparse cutting and short cutting, and the over dense branches and long branches, sick and weak branches are cut off. At this time, the spring Rhododendron has begun to have flower buds, so the over dense flower buds can be properly sparse to concentrate nutrients p>
