How to care for indoor grown oak trees

The rubber tree, also known as Indian fig and Indian rubber, is an evergreen woody foliage plant of the genus Ficus mulberry.

Rubber leaves are large, thick leathery, shiny, round to oblong-oval; The leaf surface is dark green, the back of the leaf is pale green, the initial is wrapped outside the terminal bud, and the new leaf is stretched and the supporting leaf falls off, and leaves the supporting leaf marks on the branches. Its flowery varieties have yellowish-white patches on the green leaves, which are more beautiful and pleasing to the eye.

Rubber trees are native to India and Malaysia, and are now cultivated in various parts of China. It prefers high temperatures, humidity and sunny environments, and can also tolerate shade but not cold.

Rubber trees are commonly propagated by cuttings and high pressure. Propagation by cuttings is relatively simple, easy to survive and grows quickly. It is usually carried out in combination with pruning in late spring and early summer.

Select the middle branch of annual lignification as the cutting, the cuttings should be subject to retaining three buds, cut off the lower one leaf, close the upper two leaves, and tie them with plastic, or cut off half of the upper leaf to reduce water evaporation; In order to prevent excessive loss of milk from the cut and affect survival, the wound should be smeared with plant ash in time; The processed cuttings are cut into a cuttings with river sand or vermiculite as the substrate; Keep the slotting bed with high humidity after plugging, and sprinkle water frequently on the ground (but not stagnant) to increase the air humidity. Under the temperature of 18 25 and semi-shaded conditions, it can take root after about 2 3 weeks. It is also more convenient to use high pressure in the home, and the success rate is also high.

When high pressure, select two-year-old branches, and first peel 1 cm wide on the branches; Then wrap it around the wound with moist moss or peat soil, and finally wrap it tightly with plastic film, and tie the upper and lower ends; After 1 2 months, the rooting shoots can be cut off and potted.

When the rubber tree is potted, it is advisable to use 1 part of humus soil, 1 part of garden soil and 1 part of river sand, and add a small amount of base fertilizer to prepare culture soil. It grows very quickly in hot and humid environments, producing one leaf every 5 to 10 days, during which it is necessary to ensure adequate fertilizer and water. Generally, liquid fertilizer or compound fertilizer is applied 1 or 2 times a month while maintaining high soil moisture.

In autumn, gradually reduce the frequency of fertilization and watering to promote plant growth and fullness, which is conducive to overwintering. Rubber trees like strong sunlight and should be cultivated in the sun throughout the growing season from spring to autumn, and in winter they should also be placed in strong light. But it is also shade tolerant and is better when cultivated indoors in low light. In addition, in order to make the plant grow evenly and ensure good plant shape, topping is carried out when the seedlings grow to a height of 50 to 80 cm to promote the germination of lateral branches; After the side branches grow, select 3 5 branches, and then prune the side branches briefly once a year, and after 2 or 3 years, you can obtain a larger plant with complete shape and round plumpness.

The rubber tree is moved indoors, and the maintenance should pay attention to these few matters, so that there is no water accumulation and no root rotten!

In order to learn the cultivation methods and precautions of rubber trees, we must first prepare the soil suitable for the growth of rubber trees, place it in an environment with suitable temperature for maintenance, and pay attention to mastering the method of watering and the frequency of fertilization. In addition, it is necessary to properly repot and change the soil, prune it in spring, and turn the pot every half a month when it is maintained in the sun.

Rubber trees grow more luxuriantly in loose, fertile soils with good drainage and aeration. When planting rubber trees in a potted home, you can choose humus soil: garden soil:

The ratio of river sand is 1:1:1 to configure, and some basal fertilizer can also be added.

The suitable temperature for the growth of rubber trees is between 20 and 30, so in the case of extreme temperatures in summer and winter, it is necessary to pay attention to the best temperature control work for rubber trees.

In spring and autumn when the temperature is just right for the growth of rubber trees, it is enough to water every 4 to 5 days, but in summer when the weather is too hot, it should be watered every 1 2 days, and once a week in winter when the air is dry.

Rubber trees like fertilizer, during their growth period, they need to apply 1 or 2 times a month to decompose liquid fertilizer or compound fertilizer, and after each fertilization, they should be watered thoroughly to ensure that the fertilizer penetrates into all parts of the soil.

(1) Change the pot and soil

At the beginning of the growth of the rubber tree, because it grows so luxuriantly, it is necessary to replace the larger pots every year. After 6 to 8 years of growth, it can be repotted every 3 years, and at least half of the old soil can be removed from each repot, and planted with new culture soil.

(2) Spring pruning

In the spring of each year, the rubber tree should be pruned with a major pruning to remove all the branched branches inside the canopy, and remove the fragile branches and weak branches that grow inward, so as to keep the rubber tree in a perfect shape.

(3) Turn the pot

When placing the rubber tree in the sun for maintenance, the pot should be rotated every half a month to avoid causing one side of the rubber tree to grow luxuriantly and the other side to grow very sparsely, which affects its ornamental value.

1. Soil: When cultivating rubber trees, it is necessary to choose soil rich in humus and fertile nutrients. 2. Watering:

Rubber trees do not require much water and can be watered every 7-10 days. 3. Fertilization: 1-2 times of nitrogen, phosphorus and potassium fertilizer should be applied in the peak growth season of rubber trees.

4. Precautions: cut off the overly dense branches of the rubber tree in time to avoid poor plant growth.

1. Breeding soil

The soil of rubber tree cultivation is usually mainly humus nutrient soil, and the soil quality is adjusted to slightly acidic under the premise of ensuring that the soil is fertile and loose and has high drainage quality. It is recommended to mix humus, garden soil, river sand and other materials to prepare planting soil.

2. Watering method

Soil moisture will affect the growth rhythm of rubber trees, so watering and irrigation to ensure that the potting soil is in a normal moist state, and there should be no waterlogging or drought. In summer, water needs are high, and in addition to watering, water mist should be sprayed on the plants to increase humidity.

3. Fertilizer topdressing

In the peak growth period of rubber trees, top dressing should be timely and sufficient to meet the growth needs of rubber trees. Generally, compound fertilizer or decomposed fertilizer is the main solution, which is added every other month. It is taboo to use nitrogen fertilizers, the stem nodes will grow long, and the plant shape is not beautiful.

4. Light temperature

The optimal growth temperature range of rubber trees is between 20 and 30, and it is intolerant to low temperature environments, so it is necessary to stabilize the room temperature above 10 in winter. The light should be sufficient and bright, preferably full or half sunshine, and properly shaded from strong light and ultraviolet rays.

5. Precautions

In the process of maintenance, pay attention to the rubber tree pruning and shaping, topping and topping, so as to improve the ornamental nature of the plant. Do a good job of ventilation to avoid the rubber tree from being attacked by germs and insect pests. Turn the pot more when it is light, otherwise one side of the plant will receive too much light, and it will not look good if it is biased towards growth.

The rubber tree is not too strict on the soil requirements, loose and fertile has a certain ability to retain water and fertilizer, you can use humus soil, garden soil according to the ratio of 1:2 to mix evenly, if the conditions allow, you can add a little sand permeable, so that you can meet the growth needs of the rubber tree.

Water must be sufficient, except for the dormancy period to ensure that there is sufficient water, but not water accumulation, which will lead to root rot of the plant.

Rubber trees also have high fertilizer requirements, and they can be maintained with a thin amount of liquid fertilizer every 7 to 10 days to meet their growth needs.

Rubber trees need full light during the growth period, and can grow better under sunlight, for example, the leaves will grow in size, thickness and shape, the internodes will be tight, and the terminal buds will be bright red. A shady environment causes the leaves to become smaller, the internodes to become longer, the branches to be thin, the apical buds to be smaller, and the green color changes from red to green and loses its ornamental properties.

There are relatively few pests and diseases of rubber trees, and occasionally there will be scale insects, so it can be removed in time after being found.

Rubber trees like high temperatures and are afraid of cold, so it should be properly protected below 10 degrees, and it will be damaged by frost below 5 degrees. It needs to be cultivated in full light, and it must be exposed to sunlight to make the plant shape normal and beautiful. The rubber tree is a particularly water-loving and fertilizer-loving plant, and only sufficient water and fertilizer can meet its normal growth needs.
