Maintenance/curing
1, ridging
When rubber trees are potted, humus soil 1 serving, garden soil 1 serving and river sand 1 serving should be used as culture soil, and a small amount of base fertilizer should be added.
2. Water and fertilizer
It grows very fast in a high temperature and humid environment, and a leaf can be produced every 5- 10 days. In the meantime, we must ensure adequate fertilizer and water. Generally, liquid fertilizer or compound fertilizer should be applied 1-2 times a month, while maintaining high soil moisture. After autumn, gradually reduce the number of fertilization and watering to promote plant growth and enrichment, which is conducive to wintering.
3. sunshine
Rubber trees like strong sunlight, and they should be planted in the sun from spring to autumn throughout the growing season, and also under strong light in winter; However, it is also shade-tolerant, and it is also better to cultivate in indoor weak light.
4. Choose your heart
In addition, in order to make the plant grow evenly and ensure a good plant shape, when the seedlings grow to a height of 50-80 cm, they are cored to promote the germination of lateral branches; After the lateral branches grow out, select 3-5 branches, and then cut them short once a year, and after 2-3 years, you can get a complete, round and full plant.
Precautions:
Watering: Keep the soil dry or slightly wet. Summer is the stage when rubber trees need water most, so they can be watered more. Winter is the period when rubber trees need the least water, so they need less water. Fertilization: Diammonium hydrogen phosphate and potassium dihydrogen phosphate should be topdressing in the vigorous growth season.
Lighting: Rubber trees like strong direct sunlight and are resistant to cool environment. However, during the cultivation process, direct sunlight should be received for not less than 4 hours every day. If conditions permit, it is best to ensure that plants can receive sufficient sunlight.
Ventilation: keep the environment properly ventilated.
Temperature: Rubber trees like high temperature environment, so they grow fastest in summer and autumn. The ambient temperature should be kept between 20 and 30 degrees. When the ambient temperature is lower than 10℃, the growth of rubber trees is basically at a standstill. The wintering temperature shall not be lower than 5 degrees.
