First, light. Alpine rhododendron likes semi-shading, and is not resistant to direct sunlight, so it needs to be planted in certain shading facilities or shady places. Pay attention to shade when it is hot in summer.
Second, ventilation. Indoor potted plants should be ventilated. To create a good ventilation environment, flowerpots should be placed on the balcony.
Third, the temperature. Rhododendron alpine has strong cold resistance, and the indoor potted growth temperature is about 20℃ in spring.
Fourth, fertilization. The special slow-release fertilizer and common compound flower fertilizer for rhododendron alpine can be applied according to the instructions, and the diluent for soaking fermented bean cake or bone fertilizer can also be applied according to the instructions. Pay attention to the principle of "thin fertilizer and diligent application" when applying fertilizer, and you can put a small amount of fertilizer every time you water it.
Fifth, water. Spring watering time can be mastered as appropriate. When the weather is dry, it is usually watered once every 3-5 days, and it can be extended appropriately when the weather is wet. Water should not be too frequent. It is best to water it in the morning. When watering, pour the water into the basin slowly, not too fast.
Sixth, change the pot. It is best to change pots in spring, and it is best to choose high-quality peat soil, and add some slow-release fertilizers or organic fertilizers to the new soil. When changing pots and soil, put the original soil ball into the new pot smoothly, and then cover the surrounding area with new soil, taking care not to damage the root system.
Seventh, pruning. Break off the terminal buds of the vigorous branches by hand to make them grow synchronously with the slow-growing branches. This pruning can not only reduce the loss of nutrients, but also reduce the bacterial infection caused by the direct contact of scissors with wounds. If there is no pruned plant before the terminal bud develops, it can be trimmed and shaped with scissors.
These are several aspects that should be paid attention to in the spring maintenance of Rhododendron alpine. Please refer to them!
Through our introduction, I believe everyone has a deeper understanding of how to manage Rhododendron alpine after potted flowering.
