How to grow a potted rubber plant? Foliage plant growing methods and precautions

The rubber plant (Ficus elastica) is a well-known potted foliage plant, also known as the rubber tree, Brazilian rubber, and so on. It is a large tree of the genus Ficus in the mulberry family (Moraceae), with high ornamental value, and is extremely suitable for indoor beautification and decoration. Small and medium-sized plants are often used to beautify living rooms and studies, while medium and large plants are suitable for placing on both sides of the entrance halls of large buildings and in the center of lobbies. Let us take a look at the rubber plant's growing methods and precautions together below!

The growing habits of the rubber plant

The rubber plant is native to Brazil and is now widely cultivated in the tropical regions of Asia. In China, it is cultivated in Taiwan, China, southern Fujian, Guangdong, Guangxi, Hainan and southern Yunnan, with more planting in Hainan and Yunnan. It likes a high-temperature, humid environment with plenty of sunlight. The suitable growing temperature is 20-25°C, and it dislikes direct sunlight. It can also tolerate shade but is not cold-resistant, with a safe overwintering temperature of 5°C. It tolerates dry air. It dislikes clayey soil and cannot tolerate barren or arid conditions. It prefers loose, fertile and well-drained slightly acidic soil.

Propagation methods of the rubber plant

1. Cuttings: The cutting time is in late spring and early summer, and it can be combined with pruning. For cuttings, one-year-old semi-lignified middle branches are mostly used. The wounds should be sealed promptly with clay or plant ash. The length of the cutting is based on retaining 3 buds; cut off the lower leaf, bring the upper two leaves together, and tie them with thin plastic string. Then insert them into a cutting bed with plain sand or vermiculite as the substrate. After inserting, keep the cutting bed at a relatively high humidity, but do not let it become waterlogged. The suitable temperature is 18-25°C. Frequently sprinkle water on the ground to increase air humidity, and do a good job of shading and ventilation. Roots will form in about 2-3 weeks.

2. Layering: Select a two-year-old branch of appropriate size, well developed and with solid tissue. Make a light ring-shaped peel about 1 cm wide at the part where soil is to be wrapped, and apply 30-50 ppm naphthalene acetic acid solution. Then use moist soil or a moss mixture or water-absorbed vermiculite to wrap the ringed part, bind it on the outside with plastic film, tie the lower end tightly, and leave an opening at the upper end to facilitate ventilation and watering. Pay attention to care. Layering in June will root in July-August. Once rooted, it can be cut off and potted.

Growing methods of the rubber plant

1. Temperature: The best temperature for the rubber plant is 20-25 degrees. Even above 30 degrees it can still grow well, but in winter if the temperature is too low, the rubber plant will produce a large number of fallen leaves. Its cold resistance is very poor. In the northern regions of China, it needs to overwinter in a greenhouse.

2. Light: It is indeed true that sunlight is the food of plants. In the growing methods of the rubber plant, sunlight is also a treasure. Giving it sufficient sunlight will let it grow robustly. From May to September, provide appropriate shading.

3. Fertilizing: The existence of fertilizer is like calcium supplementation, which can strengthen its “physical health”. In the growing methods of the rubber plant, fertilizing is also one of the key points. It can reduce the occurrence of markings and make the leaves become bright and beautiful. Simply using nitrogen fertilizer is enough. Remember to stop fertilizing in winter.

4. Pruning: With the arrival of spring, it is time to prune the rubber plant. Cut off the forked branches inside the crown, inward-growing branches and thin weak branches, to maintain internal ventilation as well as good light penetration and overall shape. In the usual growing methods of the rubber plant, it 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 rubber plant likes fertile, loose, slightly acidic soil. For the potting soil, it is best to use 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 rubber plant grows relatively fast and should be given plenty of fertilizer and water, but avoid water accumulation in the pot. After autumn begins, gradually reduce watering to promote solid plant growth, which is beneficial for its overwintering.

Precautions for growing the rubber plant

1. The suitable growing temperature for the rubber plant is 25-30°C. In winter, if it is below 3°C, the leaves will turn yellow and fall off, so in winter it should be placed in a sunny spot indoors and the room temperature should be kept above 10°C. In summer, when it exceeds 35°C, the plant should be moved to a cool and ventilated place for care, and water should be sprayed at the right time to lower the temperature.

2. The rubber plant is a plant of the mulberry family (Moraceae), and the whole plant contains milky sap. Therefore, after each pruning, the cut should immediately be sealed with clay or coated with charcoal powder, to avoid excessive sap flow causing dehydration and death.

3. During the seedling stage, the rubber plant needs to have the direction of the pot changed regularly, in order to avoid the plant growing toward one side, which would make the plant shape not upright and affect its appearance.

4. Generally, after the rubber plant becomes a mature seedling, as the roots grow larger and larger, the soil becomes compacted, hindering soil aeration, causing the rubber plant to turn yellow, and in severe cases it may die. It is best to repot once each spring before new buds grow. Loosen the soil once every 15-20 days until it returns to normal growth.

The growing value of the rubber plant

1. Ornamental value: The rubber plant has large, glossy leaves and remains evergreen through all four seasons. It is a large shade-tolerant foliage plant. Whether placed in ordinary homes in halls and corridors or used to decorate hotel lobbies, the potted rubber plant is a very good decorative material, and it has vigorous growth ability and does not need much care.

2. Air purification: In places with sufficient sunlight, the rubber plant can carry out vigorous photosynthesis and transpiration, regulating air humidity and oxygen content. Moreover, the rubber plant has a unique function of purifying dust, and can also absorb harmful gases such as formaldehyde among volatile organic compounds, carbon monoxide, carbon dioxide, and hydrogen fluoride in the air, purifying the stale indoor air.

3. Feng shui effect: In home feng shui, the rubber plant is related to family harmony and the cultivation of interpersonal relationships. The placement of the rubber plant will affect the family's fortune and prospects. Placing the rubber plant in an appropriate indoor position has the effect of promoting good fortune and vitality and resolving indoor yin energy and sha energy.

What to do if the rubber plant drops its leaves?

1. Insufficient light: Insufficient light is one of the reasons the rubber plant drops its leaves. The rubber plant is a sun-loving and shade-tolerant plant. Leaving the rubber plant in a dark place for a long time without sunlight can easily cause it to drop its leaves. Place the rubber plant in a place with sufficient sunlight and maintain good lighting. In winter, it is best if it can receive sunlight all day long.

2. Too low temperature: Too low temperature is also a cause of the rubber plant dropping its leaves. The rubber plant likes high temperature, high humidity and plenty of sunlight, and its suitable growing temperature is 20-25°C. Especially in winter, generally when the temperature is below 10°C, the rubber plant will begin to drop its leaves. At this time, the rubber plant needs to be moved indoors or to another warmer place for growing, but note that it should still have sunlight.

3. Improper watering: Watering the rubber plant too frequently or not watering it for a long time can both cause it to drop its leaves. During the growing period, the rubber plant must be watered frequently. Especially in the hot midsummer season, due to the large amount of evaporation, it is necessary not only to water from the roots, but also to frequently spray water on the leaf surface. However, if the potting soil of the rubber plant is too wet, the roots rot easily, so it must be watered only when the potting soil is dry.

4. Pest infestation: The rubber plant sometimes also has pest problems. Red spider mites on the leaves and scale insects on the branches and leaves can both cause leaf drop in the rubber plant. If the rubber plant is dropping its leaves, check whether it is a pest problem and deal with it promptly.

Pruning methods for the rubber plant

1. Pruning season: Pruning the rubber plant should pay attention to “prune branches in winter, control side branches in summer”. That is, in winter, carry out heavy pruning for strong trees and light pruning for weak trees, focusing on removing from the base the upright and strong competing branches. In summer pruning of the rubber plant, carry out heavy control of strong vigorous branches, control the strong and keep the weak, adjust the tree vigor to a balanced state, and grasp the principles of cutting back strong side branches, heavy pruning of sturdy branches, light pruning of weak branches, and keeping more small branches, so as to achieve the pruning goal of highlighting the trunk and promoting faster tree growth.

2. Pruning height: The pruning cuts on the rubber plant should be smooth, and splitting of the bark must be strictly prevented. The stubble height is preferably 1-2 cm. Too high or too low will affect wound healing and tree growth. The best pruning seasons for the rubber plant are early spring or late autumn and winter. In early spring, it is best before the sap flows. If pruned when the tree is sprouting, the tree body transpires quickly, loses water, and consumes much nutrition, which is not conducive to tree growth. If pruning the rubber plant in summer, be careful not to prune on cloudy and rainy days, so as to avoid the wounds being soaked in water and infected with disease.

3. Pruning techniques: In the shaping and pruning of the rubber plant, sometimes it is also necessary to highlight the growth of the trunk or main branches and remove overly dense branches or branches that affect the shape. The commonly used shaping and pruning methods to highlight the trunk and main branches are bud removal and branch thinning. That is, remove the buds that have just begun to sprout, to achieve the purpose of inhibiting the growth of side branches. The principle is to eliminate the growth of side branches in the bud stage, so that nutrients are concentrated in supplying the growth of the main branches. That is, use pruning shears to cut off branches from the base. This is often used to thin overly dense branches. Branch thinning is a remedial measure for bud removal, that is, because bud removal was not timely, side branches have already formed, and for the need to strengthen the growth of the trunk or for shaping, some excess side branches are removed.

4. Pruning and care: After pruning the rubber plant, in order to prevent excessive loss of milky sap from the cut and affect survival, the wound should promptly be coated with plant ash. Insert the prepared cuttings into a cutting bed with river sand or vermiculite as the substrate. After inserting, keep the cutting bed at relatively high humidity, and frequently sprinkle water on the ground (but do not let it become waterlogged) to increase air humidity. At a temperature of 18-25°C and under semi-shade conditions, roots will form in about 2-3 weeks.

Four-season management of the rubber plant

1. Spring management: Repot each spring when the temperature stabilizes at around 15°C, and prune appropriately before repotting. In spring, it should be placed in a sunny place, keep the potting soil moist, and frequently sprinkle and spray water around it to increase air humidity. Young plants can begin to be fertilized after new leaves emerge. When the temperature is relatively high in late spring, move it to a place with partial light or to an indoor location with scattered light for placement and cultivation.

2. Summer management: The rubber plant tolerates high temperatures and strong sun, but when the light is too strong, the leaf color easily loses its luster, which is not good for viewing. The rubber plant can be placed in a bright indoor place. Indoors with weaker light is not conducive to its growth. Because the rubber plant has many and large leaves and consumes a lot of water, it should be watered promptly to keep the potting soil moist, and at the same time spray more water on its leaves and surroundings to meet its air humidity requirements.

3. Autumn management: In autumn, the potted plant should be moved to a sunny windowsill or balcony for cultivation, keep the potting soil moist, and when the temperature is relatively high at noon, sprinkle and spray water around it and on the leaves to increase air humidity. In autumn, in order to enhance its cold resistance, it can be allowed to train outdoors under low temperatures for a period, but it must not be allowed to be hit by frost. Before frost, it should promptly be moved into a sunny indoor place.

4. Winter management: The rubber plant is not cold-resistant and can tolerate short-term low temperatures of 0°C. But the indoor temperature should be kept at around 5°C. At this time, the rubber plant's growth is in a stagnant state, so sufficient light should be ensured, and the potting soil should be kept moist but on the dry side. Too wet potting soil easily causes root rot. When the temperature is relatively high at noon, sprinkle and spray water around it and on the leaves several times. When the indoor temperature is kept above 15°C, the rubber plant can grow normally, and management can refer to spring.

The role of the rubber plant, growing methods and precautions for the rubber plant

When mentioning the rubber plant, everyone may not be very familiar with it. It is a green ornamental plant native to the tropical regions of Southeast Asia. It is a famous potted foliage plant.

Propagation of the rubber plant

Propagation methods of the rubber plant:

Cuttings are mostly used for propagation. The cutting time is suitable in spring and autumn. If summer cuttings are watered improperly, the cuttings easily rot. When cutting, cut off one-year-old semi-lignified branches, cut off the tender young part at the tip, and choose the middle section as the cutting, which has the highest survival rate. The cutting is 2-3 nodes long, retain 1 upper leaf, and cut the leaf in half, or use string to roll the retained leaf upward and tie it well, to facilitate cutting and reduce water transpiration. When cutting, first seal the upper and lower cuts of the cutting with clay to prevent excessive sap flow from affecting survival, then insert the cutting into plain sand. Under conditions above 20°C, roots can form about 40-50 days after cutting.

In addition to the above propagation by cuttings, single-bud cuttings, air layering, or water propagation can also be used.
