Pruning and flowering period control of Rhododendron yunjinensis

prune

If you prune them properly, they will bloom faster. The main way for this plant to produce new branches is through pinching. If the flowers bloom too densely, you can thin out the buds. This will ensure that the remaining flowers receive balanced nutrition and make them grow larger and more colorful. This will also help them bloom better next year.

This plant has a strong germination ability. If there are too many branches, it will not only affect its ornamental value, but will also affect its growth, so it is necessary to prune it in time. Prune off diseased, dead, or deformed branches. The time is generally chosen to be in autumn after the flowers have faded in spring. This time will not affect the flowering condition and will make the flowers bloom better in the second year.

Flowering control

They basically differentiate flower buds in autumn. By first being refrigerated for a period of time and then warming up, the flowering period can be artificially controlled, which can delay the time of flowering. The specific method is to place the flowers that have formed buds in an environment of -2-4℃. If the soil in the pot is dry, water it in time and wait until summer to put it outdoors. This way, it can bloom after 2 weeks.

If you want them to bloom before the season, you can move the potted azaleas into the greenhouse. The indoor temperature should be controlled at 20-25℃, and the humidity should also reach a certain level. You should frequently spray water around to increase the humidity. If you persist in this way for about a month and a half, they will be able to bloom. You can also try using phosphorus fertilizer 1-2 times before flowering to make the flowers grow better.
