How to raise potted rubber trees?

Rubber tree is a large tree plant of the genus Ficus of Moraceae, also known as rubber tree, Brazilian rubber, etc., with high ornamental value. It is a famous potted foliage plant, which is very suitable for indoor beautification. Small and medium-sized plants are often used to beautify the living room and study. Medium and large plants are suitable to be arranged on both sides of the foyer of large buildings and in the center of the lobby. Let's take a look at how to raise potted rubber trees.

Growth habits of rubber trees

Rubber tree is native to Brazil and is widely cultivated in tropical Asia. It is cultivated in Taiwan, southern Fujian, Guangdong, Guangxi, Hainan and southern Yunnan, especially in Hainan and Yunnan. Sex like high temperature, humid, sunny environment, suitable growth temperature 20: 25 ℃, avoid direct sunlight. It is also shady but not cold-resistant, and the safe overwintering temperature is 5 ℃. Resistant to air dryness. Avoid clayey soil, not resistant to barren and drought, like loose, fertile and well-drained slightly acidic soil.

The method of planting rubber trees

1, cutting: cutting time in late spring and early summer, can be combined with pruning, cuttings choose more than 1-year-old semi-lignified middle branches, cuttings in plain sand or frog stone as the matrix of the cutting bed, after cutting to maintain a high humidity, but not stagnant water, the appropriate temperature is 18-25 ℃, often sprinkle water to the ground to improve air humidity, and do a good job of shading and ventilation, about 2 weeks to take root.

2. Striping: select 2-year-old branches with appropriate size, good development and well-developed tissue, make a light circular peeling of about 1 cm in width in the intended part of the wrapped soil, and apply 30~50ppm 's naphthalene acetic acid solution, then wrap the ring cutting part with a mixture of wet soil or moss or vermiculite that absorbs enough water, wrap it with plastic film on the outside, tie it tightly at the lower end, and leave holes at the upper end for ventilation and irrigation. It was pressed in June and took root from July to August. After taking root, the potted plant could be cut off.

How to raise potted rubber trees?

1. Soil: rubber trees like loose, fertile and slightly acidic soil with good drainage, and are not resistant to barren. The culture soil can be mixed with rotten leaf soil, garden soil and river sand, and a small amount of cake fertilizer is applied as base fertilizer, usually turning the basin once every two years.

2. Temperature: the rubber tree likes the high temperature environment, so it grows most rapidly in summer and autumn, and the ambient temperature should be kept between 20 and 30 degrees. When the ambient temperature is lower than 10 degrees, the growth of the rubber tree is basically stagnant. The overwintering temperature should not be lower than 5 degrees.

3. Lighting: rubber trees like strong direct sunlight and are resistant to shady environment. However, in the process of cultivation, it should be exposed to not less than 4 hours of direct sunlight every day. If there are conditions, it is best to ensure that the plant can accept all-day sunlight.

4. Fertilization: rubber trees like fertilizer, but avoid nitrogen fertilizer. When there is too much nitrogen fertilizer, the stem node is only long, the leaf spacing is enlarged, and the plant shape is not beautiful. In the growing season, the young plants were topdressing 10 times of rotten liquid fertilizer mixed with 500x potassium dihydrogen phosphate once every 20 days, or 1000 times of Huaduoduo general fertilizer twice. In order to control the height of the formed plant, the mixed liquid fertilizer can be applied once every two months in the growing season.

5. Watering: rubber trees like to be wet, but avoid waterlogging and are not resistant to drought. Spring and autumn should make the basin soil in a moist state, and often sprinkle water to its leaves and around to increase air humidity. Rubber trees need a lot of water in summer, and they need to be watered every day to keep the basin soil moist and increase the frequency of watering. When the temperature is low in winter, it is better to water the basin soil moist.

6. Pruning: pruning the canopy in spring, deleting the bifurcated branches, introverted branches, withered branches and weak branches inside the crown, and truncating the branches protruding from the crown, so as to make the plant well ventilated and light permeable and keep the tree shape round. If the crown is too large, the outer branches can be truncated as a whole. Dense branches and short truncated branches should be removed at any time during growth.

Matters needing attention of rubber trees

1. The suitable temperature for rubber tree growth is 25: 30 ℃. If the leaf is lower than 3 ℃ in winter, the leaves will turn yellow and fall off, so it should be placed in the sunny place indoors in winter and keep the room temperature above 10 ℃. When more than 35 ℃ in summer, the plant should be moved to a cool and ventilated place for maintenance, and timely water spray to cool down.

2. Rubber tree is a plant of Moraceae, and the whole plant contains milk. Therefore, immediately after each pruning, the incision should be blocked with cement or coated with charcoal powder, so as not to drain too much juice and cause water loss and death.

3. Rubber trees need to change the direction of the pot regularly in the seedling stage in order to prevent the plant from growing on one side, resulting in small and correct plant shape and beautiful appearance.

4. After the growth of rubber tree seedlings, the roots are getting bigger and bigger, which causes soil hardening, hinders soil ventilation, and causes rubber trees to turn yellow and die seriously. It is advisable to change the basin before the new buds grow every spring and loosen the soil every 15 to 20 days until it returns to normal growth.
