1. Flowering management

Spring is the middle and late flowering period of Rhododendron, which needs to be managed and protected. The specific methods vary from variety to variety. For new varieties, we should give them stable light, appropriate temperature and appropriate water, stop fertilization and control diseases and pests

For Rhododendron varieties after flowering, it is necessary to cut off the residual flowers in time after their flowers bloom and fall, apply fertilizer appropriately to promote the germination of new buds, and control the development direction and length of new buds by pruning and coring, so as to make the plant type as plump as possible

2. Bud control

The growth of Rhododendron is relatively slow and can form itself. The shape of natural growth is more beautiful, and it doesn't need too much trouble to prune. However, in spring, the germination of new buds will make the nutrient distribution of the whole plant uneven, and individual buds will grow very fast, prosperous and vigorous. At this time, the bud needs to be removed from the base to prevent it from growing too strong and causing plant type disorder

3. Delayed exit

Don't rush to move the cuckoo maintained indoors to the outside to prevent it from catching a cold. In northern areas, it should wait until the room temperature stabilizes above 15 ℃ before leaving the room, so that it will not be affected by the cold weather in late spring or great changes

4. Pest prevention

In spring, aphids also need to be prevented. The relatively dry environment in spring is more suitable for the growth and reproduction of aphids. Aphids can be lured by hanging yellow boards at home to achieve the purpose of pest control
