A single-pole rubber tree is so ugly. Let's use the method of three branches and nine tops to fix the shape.

How to prevent the rubber tree ejector pole from growing too high

I have to say, the top advantage of the rubber tree is very strong!

Without pruning, the apical buds of the rubber tree will sprout continuously, the main rod will grow higher and higher, and its axillary buds will be latent for a long time, making the main rod a "single pole".

Oh, a hundred thousand is ugly. I can't stand it.

In order to control the rubber tree to grow too tall, if it is a family cultivation of rubber tree, do not put on the big pot in the first place. In this way, when changing the pot, only do some pruning of the root system, and still plant it into the original pot to prevent the plant from growing too big.

If the cuttage propagation is carried out and the cuttings grow to a certain height, they should be cut short according to their personal preferences.

After shearing, 3-5 lateral branches can be sent out at the same time. If the lateral branches germinate too much, they can be erased properly, leaving 3 backbone branches.

When it grows to a certain height, it should be cut short again. After germination, there are three more branches on each backbone branch, thus forming the so-called basic tree shape of "three branches and nine tops".

Since then, pruning will still be carried out in the first and middle of May every year.

Pruning method: remove dense branches, disease and insect branches, cross branches, parallel branches and senescent branches, and cut short long branches to maintain a round, beautiful crown and tree shape.

In addition to being ugly, the leaves of rubber trees are also ugly.

So why do the leaves of rubber trees turn yellow?

When the rubber tree is still a small seedling, the basin needs to be changed every spring, and the basin diameter should be larger every year, and the basin can be changed every 2-3 years after the adult tree is grown up.

If the basin is not changed for a long time, it will seriously harden the basin soil, hinder the ventilation of the soil, cause asphyxiation and necrosis of the fibrous roots of rubber trees, and cause plant leaves to wither and yellow.

Taiwan friends, please remember that after the general potted rubber trees become seedlings, it is advisable to change the pots once before the new buds grow every spring.

When changing the basin, properly cut off the crimped root system and part of the dead root system, and add new culture soil and base fertilizer, the basin soil can be loosened every 15-20 days until the normal growth of rubber tree plant is restored.

Finally, the director would like to talk about the growth of rubber trees at the same time. If not, he is always worried about the lack of a basic link.

Growth factors of rubber tree

[light]

Like warm, moist, bright light environment, avoid direct sunlight.

[temperature]

The suitable temperature for growth is 20-25 ℃.

[soil]

Like fertile, loose, slightly acidic soil.

The basin soil should be prepared with 4 parts of rotten leaf soil, grass ash soil plus about 1 part of river sand and a small amount of base fertilizer.

[watering]

High temperature in summer, rubber trees grow faster, should be fat and water, but to avoid stagnant water in the basin.

Gradually reduce watering after entering autumn, promote plant growth and enrichment, which is conducive to its overwintering.

[fertilization]

The young plants were topdressing 10 times of rotten liquid fertilizer and 500 times of potassium dihydrogen phosphate solution every 20 days in the growing season. The mixed liquid fertilizer was applied every 2 months in the growing season of the formed plant.

[reproduction]

Multi-use cutting method, and in late spring and early summer, can be combined with pruning.

Methods of reproduction:

1. Cuttings often choose one-year-old and half-lignified middle branches.

two。 After cutting the cuttings, seal the cut with cement or plant ash.

3. The length of cuttings is to keep 3 buds as the standard, cut off the lower 1 leaf, close the upper 2 leaves, tie them with thin plastic rope, and cut them on the cutter with plain sand or vermiculite as substrate.

4. Keep the plug-in bed with high humidity after insertion, but do not accumulate water, the suitable temperature is 18-25 ℃, often sprinkle water to the ground to improve air humidity, and do a good job of shading and ventilation, it can take root in 2-3 weeks.

OK, after the supplement, that's all for this article. I don't know if what the station director said was clear and detailed. For those Taiwanese who do not understand it, the director has written a hidden poem for you. It may not be well written, but it can help you find the director.

More wonderful articles are found in a Tibetan head poem:

The breeze caresses the flowers

Wander through Nanshanyang

Sou Qi Qiao Bronze Sparrow platform

Plant red plants on the green clouds

-- to challenge: four poems with hidden head and tail, the first word is connected with the last word, you can get the eight-character motto and summon the head of the stage to be real! Remember to say when you come: "Director, I have cracked your secret."
