Trimming, removing the core and thinning the buds, if the core is removed in time, it can open faster, so pay attention to this, and remove the core before flowering. If there are too many buds, it will cause flowers to cluster together prematurely, but this is not beautiful, so we should take off the extra buds in time. After picking it, the flowers will not only be bigger, but also look better.

Pruning Because this plant has strong germination ability, proper pruning can make them grow better. If it is not trimmed, it will greatly affect the viewing effect. Pruning time is generally chosen in the backward or autumn of flowers, which will not affect their normal growth. Cut off branches that are sick or have bugs. Such a branch is already sick, and may not only be transfected into nearby branches, but also take away some nutrients. It is also necessary to cut off cross, overgrown, overlapping and dense branches, which will affect the overall appearance and separate some nutrients.

The flowering period controls the differentiation of autumn flower buds, and the flowering period is mainly adjusted by adjusting the temperature during the period. There are two ways. One is suitable for them to blossom ahead of time. Potted azaleas can be directly cultured indoors. In addition to keeping the temperature at 20-25℃, water should be sprayed frequently to control the ambient humidity above 80% so that they can bloom after 45 days.

The second method is suitable for friends who want to delay flowering. Put the rhododendron with bud at low temperature, keep it at 2-4℃, water it when the soil is too dry, and put it back outdoors in summer, so that it can bloom in the first half of the month.
