1、 Winter management
1. Temperature: when the Rhododendron spends the winter, the maintenance temperature should not be too low. It should spend the winter at 8-10 ℃. Generally, if you keep it indoors at ordinary times, you should move indoors when the temperature drops, and you can't suffer from the cold wind. If you can't move outdoors, you can put on plastic film to keep out the cold p>
2. Water: plants will grow slowly during overwintering, so they will not absorb water as they do during growth. To reduce the number of watering, it is generally enough to water once a week or so. If you water too much, the soil will rot if it is too wet. Rain or snow water can be used for watering, but the temperature of the water cannot be too low p>
3. Fertilization: fertilization is usually not needed in winter, but it should be applied once in January to accumulate nutrients for spring flowering p>
4. Pruning: pruning and shaping can be carried out during the winter, mainly to cut off the dense branches, as well as the residual branches, weak branches and diseased branches. The shape of the pruned plant will be better p>
2、 The reason why the leaves turn yellow
There is not one reason for the yellowing of leaves. Too little watering, too low temperature, too much light intensity or alkaline soil during the maintenance period will turn the leaves of the plant yellow. What kind of cause is it? We need to find out the cause according to the usual maintenance and solve it after finding the cause p>
