Talking about the method of High pressure Propagation of Rhododendron

There are many ways to reproduce azaleas, and if they are mass-produced, they mainly choose the insertion method of vegetative reproduction. In addition, there is another method that is not commonly used, but it is also the healthiest method for plants in science. That is the breeding method of azaleas. Also known as plastic bag high pressure method. Now let's learn the steps and techniques of high-pressure propagation of azaleas.

Propagation methods and steps of rhododendron:

1. Choose the part of a branch that is 3-5 years old, and the length of the ring peeling part can be determined according to the thickness of the branch. The branch is thinner and the length can be shorter. The peeling tool can use the right thumbnail, after the selected part. Gently peel it from top to bottom, or use a knife to carve a circle around the upper and lower ends, then gently peel off the cortex.

2. After the ring peeling, use a suitable plastic film to surround the peeling place to form a cylinder, and the lower end is first fastened with thread or lead wire. The place of piercing is about 2 centimeters at the lower end of the peeling place. The slightly acidic soil that has been wet with water is gradually added to the plastic drum, and if 1/5 moss is added to the soil, the effect will be better, which can maintain the constant humidity in the plastic bag, help prevent drying, and promote early healing and early rooting. When the soil is filled, tie the upper end firmly with thread or thin lead wire to form a shape the size of an egg, put it outside and let it go to the sun and rain, and carry out daily fertilization, watering and other maintenance. Usually, it is best to spray some water on the leaf surface when watering, so that the water slowly seeps into the plastic bag from the branches and leaves, increasing the humidity in the bag, but be careful not to be too wet, can be partial to some, it is too wet to heal and take root slowly.

3. The high-pressure method of rhododendron propagation is also suitable for spring rhododendron, hairy leaf rhododendron, etc., but it must be carried out after the flower fades. Summer cuckoos can take shape in June after the flowers fade. It can take root after 3-4 months, and the survival rate can reach more than 90%. Then cut off the plastic bag together, gently remove the wire or lead wire, peel off the plastic film, and plant it in other pots, so as to become a new rhododendron plant, and the next year will be able to produce bright flowers, this method is very simple.
