Does the rubber tree need topping? Rubber trees need topping. After topping, the shaping and pruning of lateral branches should be promoted to help rubber trees grow better and look more beautiful.
How high the rubber tree is, the top of the rubber tree will generally be about 50cm. If you want to lower it, you can do it about 30cm, but the specific height can be determined according to your own preferences.
What does the rubber tree look like when it hits the top? Pay attention when coring, as long as the 1/3 of the new tip of rubber tree is removed, the 1-3 leaves at the front end of the branch after coring should also be removed. In fact, pinching can also control the growth of plants, and the height of pinching should be close to the diameter of the flowerpot, so that the rubber tree will be more beautiful.
How long does it take for rubber trees to grow new leaves after topping? Rubber trees like high temperature environment. Summer is the peak of their growth. If the indoor temperature is lower than 20 degrees in winter, they almost stop growing, and a new leaf can grow in about 10 days in summer.
When is the best time to top the rubber tree? The best topping time of rubber trees is generally from late May to mid-June, and summer is more suitable.
The topping method of rubber tree includes the following steps: removing the terminal buds of branches or cutting off the top of branches to promote them to germinate side branches. The principle is to remove the top bud of the main branch, eliminate the top advantage, and make the side buds germinate and grow. Specifically, when the rubber tree grows to a suitable height, generally 30-50 cm high, its vertical growth can be changed by pinching the roots to promote the germination of lateral buds.
Generally, 2-3 lateral buds near the top of branches are easy to germinate. After the lateral branches grow out, the tree is cup-shaped or Y-shaped, so the coring operation is extremely easy, but it is very important to grasp the coring height. If the coring height is too high, it is easy to make the whole tree heavy and light, which will affect its ornamental value. The height of coring should be close to the diameter of flowerpot, not too high or too low.
For some trees that have formed an upright tree shape because it is too late to core, methods such as short cutting, bud carving and branch pulling can be used to remedy, so that the exposed part of the lower part germinates side branches, and at the same time, the angle of the main branch is changed to achieve the purpose of perfecting its shape.
Precautions for rubber tree topping 1. Fertilization: Fertilization is essential after topping. Only when there is enough fertilizer can the lateral buds grow rapidly. In order to make the lateral buds grow rapidly, nitrogen fertilizer should be used as the main fertilizer, and potassium fertilizer should be used together to make the stems have prizes.
2. Illumination: After topping, more illumination should be given to rubber trees to promote photosynthesis, so as to produce more nutrients for plant growth. At the same time, the place with bright light will be warmer, which is beneficial to the germination of lateral buds.
