Rubber tree cultivation methods and precautions

The leaves of the rubber tree are very beautiful and shiny. Most importantly, it can purify the air, making it a very pleasing potted plant in the home. More and more people use rubber trees for beautification and decoration. So what are the methods and precautions for growing rubber trees? Let's take a look.

How to grow rubber trees

1. Lighting

Rubber trees prefer warm, humid and bright environments and avoid direct sunlight.

2. Temperature

The most suitable temperature for rubber tree growth is 20℃ to 25℃.

3. Soil

The soil for rubber trees is fertile, loose, and slightly acidic. It is recommended to use 4 parts of leaf mold, grass ash soil, about 1 part of river sand, and a small amount of base fertilizer to prepare the potting soil.

4. Watering

In summer, the temperature is high and the rubber tree grows very fast, so it is best to apply a lot of fertilizer and water, but be careful not to let water accumulate in the pot. After the weather gradually turns cooler in autumn, it is necessary to gradually reduce watering to promote the growth of the rubber tree, which is beneficial for wintering.

5. Fertilization

Young rubber trees should be topdressed with 10 times decomposed liquid fertilizer mixed with an equal amount of 500 times potassium dihydrogen phosphate liquid once every 20 days, while established plants only need to be topdressed with the mixed fertilizer once every two months.

Precautions for rubber tree cultivation

1. Disease and pest control

Rubber trees are most susceptible to anthracnose during the high temperatures of summer, with leaves being the main affected part. Symptoms include round or oval gray spots on both sides of the leaf veins. In severe cases, the spots may connect into one piece and spread to the entire leaf.

2. Place in a ventilated and light-permeable place

Rubber tree bonsai should generally be placed in a well-ventilated and light-permeable place with a certain amount of humidity, sufficient sunlight, and smooth ventilation. Otherwise, the rubber tree will easily turn yellow and dry, leading to the occurrence of pests and diseases, and even death. It is recommended to enter the greenhouse for heat preservation management in winter.
