Rubber trees grow very fast and can grow very tall if you are not careful. Not only does it look unsightly when kept at home, but it also takes up space. Therefore, during the breeding process, you must pay attention to pruning to control its growth height. .
So, how to prune rubber trees to prevent them from growing taller? For many novices, rubber tree pruning is indeed a difficult problem for novices.
Next, the editor will introduce to you the process of pruning rubber trees, let’s take a look.
When to prune rubber trees? If you just want to prune, you can do it any time of the year. But if you want to propagate the cut branches, you should choose late spring and early summer, which will facilitate the production of cut branches. Multiple sprout points are beneficial to the fullness of the tree.
When pruning rubber trees, pay attention to pruning in winter and controlling branches in summer.
That is, in winter, strong trees should be pruned heavily and weak trees should be pruned lightly, focusing on pruning the upright and strong competing branches from the base.
When pruning rubber trees in summer, implement strong control of strong branches, control strong branches and leave weak branches, adjust the tree situation to balance, and master the principles of starting from the strong side, pruning strong branches heavily, pruning weak branches lightly, and leaving more small branches. The purpose of pruning is to highlight the main trunk and promote the growth of trees.
How to prune and chop rubber trees? Sometimes our rubber trees have been growing for a long time and the tree shape is relatively tall. In fact, the principle of pruning at this time is to chop off the heads and suppress the buds to promote branching. We only need to follow our Just cut off the upper part of the desired height.
Before considering beheading a rubber tree, we must first determine the status of the rubber tree. Only strong and healthy rubber trees will have a lower risk of beheading, because without the photosynthesis of leaves, if the root system is no longer good, , it is easier to die.
Generally speaking, you can behead the rubber tree as long as it can keep growing. However, to be on the safe side, it is recommended to behead the rubber tree in summer, because summer is the peak growth season for rubber trees, and the time to hold back the buds is short and the risk is small. .
In addition, some flower friends don’t know where to start. This is actually very easy. We only need an ideal height, and we need to observe whether there are any buds below.
Also, if you have a pruning knife, it will be easier to behead. If not, it is recommended to use a sharp one to cut the circumference and then cut it. If the incision is qualified, it is best to seal it with wax (that is, use candle drops) some candle oil).
What are the pruning methods of rubber trees? 1. Topping: The principle is that the top buds of the main branches are removed and the top advantage is eliminated, allowing the side buds to germinate and grow.
The specific method is that when the rubber tree grows to a suitable height, usually 30 to 50 cm high, its upright growth can be changed by topping to promote the germination of side buds.
Generally, the 2 to 3 lateral buds near the top of the branch germinate easily. After the lateral branches grow out, the tree will take on a cup-like or Y-shaped shape. For rubber tree pruning, the topping operation is relatively easy.
2. Short cutting: This is a method of cutting off the upper 1/3 or 1/2 of the entire main branch to encourage the main trunk to sprout side branches.
The principle is to cut off the top branches, eliminating the top advantage so that the buds below the cut can germinate and grow.
The pruning cuts of rubber trees should be smooth to prevent wall cracks.
The appropriate stubble height is 1 cm to 2 cm.
Too high or too low will affect wound healing and tree growth.
3. Shaping and pruning technology to promote side branches: Rubber trees have a strong top advantage, and side buds are generally difficult to germinate. Without shaping, it is easy to grow upright and form an upright shape.
When it grows to a certain height, firstly, it is too tall to be placed indoors; secondly, after the lower leaves fall off, it is easy to become a heavy-top-heavy-low-light shape with lush upper branches and bare lower parts. Ornamental value.
We now introduce several simple and easy methods to inhibit its height growth and promote the change of shape of side branches.
4. Pulling branches: Pulling branches means changing the extension direction of branches in space through external force. The principle is that by pulling branches, the polarity of branches is changed, that is, the apical advantage of the terminal buds is weakened or eliminated. , the greater the angle of pulling the branch, the stronger its top advantage will be weakened. If it is pulled to a horizontal state, its top advantage will be completely eliminated.
The specific operation is: pull the bud-promoting part into an arc, so that the bud-promoting part is at the top advantageous part. If the branches are pulled in spring, the formation of side branches can be promoted that year.
5. Rubber tree pruning season: When pruning rubber trees, pay attention to pruning in winter and controlling branches in summer.
That is, in winter, strong trees should be pruned heavily and weak trees should be pruned lightly, focusing on pruning the upright and strong competing branches from the base.
When pruning rubber trees in summer, implement strong control of strong branches, control strong branches and leave weak branches, adjust the tree situation to balance, and master the principles of starting from the strong side, pruning strong branches heavily, pruning weak branches lightly, and leaving more small branches. The purpose of pruning is to highlight the main trunk and promote the growth of trees.
