Wax leaf Rhododendron's growth ability is very strong, so we should pay attention to timely pruning to maintain the overall appearance.
In the seedling stage, the main task is to remove the heart. When the branches grow to about five centimeters long, they should remove the heart buds. In this way, two or three new buds will sprout on the top of each new branch. Sticking to the heart removal will help the plants to increase their branches, make their branches and leaves more luxuriant and their crowns more three-dimensional.
The flower bud that grows out in seedling period also wants to eliminate immediately, reduce the consumption of nutrition component, promote the growth of branch and leaf effectively..
In the growth period, when the branches are too dense, prune the dense twigs, residual branches and weak branches in the crown as soon as possible, improve the ventilation and light transmittance of the crown, and promote good development.
The formed plants should be pruned after the annual flowering period or before overwintering in autumn. At this time, the pruning should cut off the new shoots, which will hinder the overall growth of the plant and waste a lot of nutrients, so it is necessary to cut them off in time, and cooperate with pruning the too dense weak branches and diseased branches in the crown, which is conducive to improving the quantity and quality of flowering.
When the growth of adult plants slows down and starts to decline, prune the whole plant. At this time, pruning is to save nutrients, provide enough nutrients for the branches to keep growing, and stimulate the growth of new branches.
The flowering period of Rhododendron wax leaf can be controlled by adjusting the temperature.
If you want to let the flowering come ahead of time, you can put the Rhododendron in a warm environment with an average temperature of about 20-25 ℃. Pay attention to watering the Rhododendron plants frequently to keep the leaves moist. The humidity of the air is better controlled at 80% or above, about 40-50 days can let the Rhododendron blossom ahead of time.
If you want to delay its flowering, you can control the environmental temperature at 2-4 ℃ after the bud germination of Rhododendron wax leaf, reduce the supply of water, wait until the soil is dry and then water, you can delay the opening of flowers, if you want to make it bloom, as long as half a month in advance to gradually move the plant to a normal temperature environment suitable for flowering.
