[culture method] how does the indoor beautification plant "rubber tree" grow fast? How to apply fertilizer is the most correct? What's the difference between Black King Kong and Black King Kong?

Rubber tree is a relatively easy to manage indoor ornamental plant, can be placed anywhere in the home, but we need to take good care of it at home. So how do rubber trees grow fast? How to apply fertilizer is the most correct? What's the difference between Black King Kong and Black King Kong? The details are as follows:

First, how do rubber trees grow fast?

1. Soil conditions

Rubber tree is actually a kind of plant that is not tolerant to barren soil, which can lead to slow growth or stagnation if it grows in poor soil. Rubber trees like slightly acidic soils that are fertile, loose and well drained. It is very disadvantageous to the growth of rubber trees if they are raised in clayey soil.

Therefore, we can prepare a fertile soil for the rubber tree. We can use garden soil, rotten leaf soil, sawdust and river sand to prepare rubber tree culture soil. This kind of soil has the characteristics of sufficient nutrients, looseness and good water permeability, so it is suitable for raising rubber trees.

2. Temperature condition

The best growth temperature of rubber tree is between 18 and 28 ℃, which is not resistant to cold. If the winter temperature is lower than 5 ℃, it may lead to frost injury. High temperatures in summer will slow down the growth rate of rubber trees.

3. Lighting conditions

In fact, the rubber tree does not require much light, and it is a kind of plant that is more tolerant to shade. The growth rate of breeding in dark places will slow down, but the plants will not lose their leaves in a short period of time. If there is not enough light for a long time, it will lead to growth stagnation. In spring, autumn and winter, except for the noon sun, it can be exposed to the sun at any other time, which is beneficial to its growth.

4. Nutrient conditions

As mentioned above, rubber trees do not tolerate barren and like to be fertile, so we can also promote the rapid growth of rubber trees by adding some nutrients. If long-term nutrient deficiency will not only inhibit its growth, but also lead to a variety of poor growth phenomena. For example, the lack of nutrients leads to the decline of disease resistance, prone to diseases and insect pests and so on.

5. Watering conditions

The humidity of the soil will also affect its growth rate, so daily watering should be timely, but also to keep the soil in a moist state. But in winter, we should be careful not to let the soil be too moist and cause rotting roots.

6. Pruning conditions

Proper pruning can make plants grow more vigorously. The time of pruning can be chosen in spring, and the parts of diseases and insect pests, branches and leaves can be pruned together, so as to reduce the loss of nutrients.

Second, how to fertilize rubber trees is the most correct?

1. Fertilization in summer

Rubber trees grow vigorously, so it is the time when rubber trees grow rapidly in the middle of summer, when the demand for water and nutrients will increase, so we have to increase the frequency of fertilization and use rotten cakes to soak into water. then mixed with phosphorus and potassium liquid fertilizer is applied, fertilization in spring and autumn is usually carried out every three weeks, and summer can be reduced to two Mondays. Fertilizing is carried out with watering, which can make the rubber tree grow healthier and stronger.

2. Fertilization in spring

Rubber trees in the early spring every year, the soil in the flowerpot will be poured out to replace it to ensure the nutrients of the potted soil base fertilizer. At this point, the root system can be trimmed, and then the new soil can be selected for basin. If the rubber tree grows bigger, choose a larger flowerpot at this time, which can be conducive to normal growth. If you want the potted rubber tree to grow fuller, you can disturb the growth of its seedlings and control its height at about 70 cm, which will make the planted rubber tree more beautiful.

What is the difference between the rubber tree and the Black King Kong?

Both are rubber trees, but the leaves of Black King Kong are black and the leaves of rubber trees are green. Black King Kong can grow lateral buds without topping, and rubber trees will not grow lateral buds without topping.

Fourth, the reasons why rubber trees always turn yellow and lose their leaves are as follows:

1. The light should be sufficient.

Growth needs an environment with plenty of sunshine, and yellow leaves and fallen leaves often appear when there is too little light. A friend of mine keeps a pot of black King Kong on the open-air balcony. The leaves are huge and thick, and they are very lovely.

2. The temperature should not be too low.

The suitable temperature for growth is between 20 ℃ and 30 ℃, and the growth is the most luxuriant at 25 ℃-30 ℃. The growth is poor when it is less than 10 ℃, and it is easy to suffer frost injury when it is less than 0 ℃. If the temperature is too low, there will be yellow leaves and fallen leaves.

3. Watering should be appropriate

Like ordinary rubber trees, Black King Kong is not resistant to waterlogging, too much watering will lead to yellow leaves and fallen leaves. Watering should follow the principle of "dry and wet". Don't water too often. Especially when the winter is in a semi-dormant state, when the growth is slow, it is necessary to water less.

Conclusion: the above are the key points of rubber tree culture and care. I hope I can help you.
