What are the propagation methods for the Indian rubber tree? A detailed guide

The Indian rubber tree (detailed introduction) is a tropical tree species, widely cultivated across our country, especially as a potted plant in cities, where its popularity is extremely high. When cultivating the Indian rubber tree in the north, attention must be paid to overwintering it in a greenhouse. Artificial propagation of the Indian rubber tree can be done by sowing seeds or by cuttings. The editor will now briefly introduce the propagation methods of the Indian rubber tree.

Indian rubber tree

The Indian rubber tree is commonly propagated by sowing and cuttings. For seed propagation, the harvested seeds need to be stored in sand; in late March of the following year, they are sown in drills in an open seedbed with a row spacing of 20-25 cm. The seedlings are afraid of the sun, so after emergence, reed curtains should be set up for shade; in the second year the reed curtains can be removed; in early spring of the third year the seedlings are transplanted once, and after another year of growing they can leave the nursery. For cutting propagation, the seedling of the Chinese holly grows slowly, so cutting propagation is mostly used. In the Yangtze River basin, open-field cuttings can be taken during the plum rain season, while in the north, pot cuttings should be taken in May. For open-field cuttings, two-year-old branches should be collected as cuttings, with a cutting length of 12-15 cm and inserted 6-8 cm deep into the soil; for pot cuttings, one-year-old tender shoots should be collected as cuttings, with a cutting length of 8-10 cm, keeping 1-2 leaves at the tip and cutting off 1/2 of them, inserted 4-5 cm deep into plain sandy soil. Whether planted in the ground or in pots, they should be kept shaded during care; for pot cuttings in the north, water should be sprayed frequently to increase air humidity. After 45 days, roots will gradually form.

Introduction to the cultivation methods of the Indian rubber tree

The Indian rubber tree is an evergreen tree of the genus Ficus in the mulberry family, native to India, and widely cultivated across our country. Its leaves are large and glossy, and it stays green all year round, making it a common foliage tree species. Potted plants can be displayed in living rooms and bedrooms as decoration, and it is often used to beautify the environment in hotels and restaurants. In warm regions it can be cultivated in the open ground as a street tree or landscape tree. Now let us take a look at the cultivation methods of the Indian rubber tree!

Growth habits of the Indian rubber tree

The Indian rubber tree is a tropical tree species, native to India, Myanmar and Sri Lanka, among other places. It likes to grow in a warm, humid environment with plenty of sunlight, and is not cold-tolerant; in relatively cold environments, the Indian rubber tree finds it very hard to survive. In addition, the Indian rubber tree rather likes fertilizer, so when cultivating it, it is best to choose fertile soil for planting the Indian rubber tree.

Propagation methods of the Indian rubber tree

The Indian rubber tree is mainly propagated by cuttings, and can also be propagated by layering. For cutting propagation of the Indian rubber tree, May to September is suitable; when taking cuttings, select 1-2 year old Indian rubber tree branches and cut them into sections of 3-4 nodes each for insertion. Note that when taking cuttings, slaked lime powder or plant ash should immediately be applied to the cut surface of the severed branch, and pressed firmly with the thumb for three to five minutes to prevent the loss of sap. Each branch should retain one to two leaves to allow for better rooting. In addition, the cutting temperature is best kept above 15°C.

Cultivation methods of the Indian rubber tree

1. Temperature: The best temperature for the Indian rubber tree is 20-25°C; even above 30°C it can still grow well. However, in winter, if the temperature is too low, the rubber tree will shed a large number of leaves, and its cold tolerance is very poor. In the northern regions of our country, it needs to overwinter in a greenhouse.

2. Light: It is indeed true that sunlight is the food of plants, and in the cultivation methods of the Indian rubber tree, sunlight is also a treasure; giving it sufficient sunlight allows it to grow vigorously. From May to September, provide appropriate shade.

3. Fertilizing: Fertilizer is like calcium supplements, strengthening its "physical health." In the cultivation methods of the Indian rubber tree, fertilizing is also one of the key points; it can reduce the occurrence of markings and make the leaves more glossy. Simply using nitrogen fertilizer is enough, and remember to stop fertilizing in winter.

4. Pruning: With the arrival of spring, the Indian rubber tree reaches pruning time. Cut away the forked branches inside the crown, the inward-growing branches and the thin, weak branches, to maintain internal ventilation as well as good light penetration and the overall shape. Usually, in the cultivation methods of the Indian rubber tree, the pot must be repotted once every 2 years, adding materials such as leaf mold soil and re-mixing. It prefers loose and well-drained loam.

5. Soil: The Indian rubber tree likes fertile, loose, slightly acidic soil. The potting soil should be prepared with 4 parts leaf mold soil, grass-ash soil plus about one part river sand and a small amount of base fertilizer.

6. Watering: In the hot summer season, the Indian rubber tree grows relatively fast, so it should be given plenty of fertilizer and water, but avoid waterlogging in the pot. After autumn begins, gradually reduce watering to promote solid plant growth, which helps it overwinter.

How to grow the Indian rubber tree, cultivation methods of the Indian rubber tree

The Indian rubber tree is a tropical tree species. Its leaves are large and glossy, and it is evergreen all year round, making it a very common foliage tree species. Therefore, many people like to keep it in pots in living rooms or bedrooms, adding a bit of green and vitality to the room. As for its growing environment, the rubber tree loves warmth and humidity, and also likes sunlight. Its optimal growing temperature is between 20-25°C. In China, potted cultivation is extremely widespread. Below, the editor will give everyone a brief introduction to the cultivation methods of the Indian rubber tree.

Propagation methods

The propagation methods of the Indian rubber tree mainly include cuttings and layering. Cuttings are relatively simple, and the survival rate and growth rate of the rubber tree are also relatively high. Generally speaking, rubber tree cuttings are mainly carried out in late spring and early summer together with pruning. Select a robust branch from the middle of the rubber tree as the cutting, keeping three buds on the cutting; the latex flowing from its cut end must coagulate, or some charcoal ash and rice husk ash can be used to absorb it dry, then insert it into a cutting bed with river sand or vermiculite as the substrate, keeping the cutting's growing environment between 18-25°C. After about 30 days, the cutting can take root. When the rooted rubber tree cutting grows 2 leaves, it can be transplanted into a pot.

The survival rate of air layering propagation of the rubber tree is very high. When layering, it is best to choose branches that grew in the second year. First, make a girdle 0.5-1 cm wide on the rubber tree branch, then wrap it with moist moss or plastic film and peat soil. While keeping it moist, after the rubber tree has rooted, cut off the rooted branch and plant it in soil to grow into a new rubber tree.

Care methods

The Indian rubber tree likes fertility. Newly grown seedlings need a lot of nutrients, so fertile, loose sandy loam rich in humus, leaf mold soil and garden soil should be chosen as the growing medium. In addition, during the seedling growth period, attention should be paid to applying a small amount of cake fertilizer as base fertilizer to ensure the fertility of the soil. The rubber tree is averse to nitrogen fertilizer; when there is too much nitrogen fertilizer, the rubber tree's plant shape is not attractive, so nitrogen fertilizer should be applied sparingly.

The Indian rubber tree likes water and moisture, and its water demand is even greater in summer. When cultivating it, be careful to water the rubber tree every day. On the premise of keeping the potting soil moist, increase the number of times of sunning the water. It is worth reminding that the Indian rubber tree is averse to waterlogging and is not drought-tolerant. When caring for the rubber tree in winter, the soil only needs to be moist.

As a tropical tree species, the Indian rubber tree has relatively strict requirements for light and temperature. The rubber tree likes light, and from spring to autumn it should be placed outdoors in a sunny spot for care. If it is kept indoors for a long time, it is very easy to cause the rubber tree's leaves to turn yellow and fall off. After winter begins, the temperature drops sharply, and the rubber tree should be moved indoors to a sunny spot for care, taking care that the indoor temperature must remain above 10°C. When the temperature rises again at the end of April and the beginning of May the following year, move the rubber tree outdoors again for care.

After the rubber tree is transplanted into a pot, be careful to loosen the soil in the pot. Generally, the best time to loosen the soil is in spring each year when the rubber tree grows new buds. And when the rubber tree grows too large, you can also replace it with a slightly larger pot.

Conclusion: The above is the editor's introduction to how to grow the Indian rubber tree and the cultivation methods of the Indian rubber tree. Friends who love the Indian rubber tree might as well give it a try. A fully grown Indian rubber tree is green all over. Placed in the living room or study, it can both green the environment and purify the air, so why not do it.
