Will rubber trees blossom?

Rubber tree originated in Brazil, is now widely cultivated in tropical Asia, like high temperature, humid, sunny environment, suitable growth temperature 20: 25 ℃, avoid direct sunlight, can bear shade but not cold, safe overwintering temperature is 5 ℃, resistant to air dryness, avoid clay, not resistant to barren and drought, let's take a look at whether the rubber tree will blossom!

Will rubber trees blossom?

Rubber trees blossom. The flowers of rubber trees are small and have no petals, and many small flowers are hidden in a small jar-like receptacle, just like their close relative banyan, which usually blossoms from May to July and lasts for several months in the primitive environment. The rubber tree has a hidden inflorescence, and there are no common flowers. the very small flowers are hidden on the inner wall of the invisible receptacle. There is a small hole at the top of the receptacle, which communicates with the outside, and the bug can go in and out of the hole to pollinate the florets inside.

Rubber tree pruning method

1. Pruning season: the pruning of rubber trees should pay attention to "winter pruning, summer control side". That is, heavy pruning of strong trees and light pruning of weak trees in winter, with emphasis on pruning upright and strong competitive branches from the base. In summer, the pruning of rubber trees should be carried out to re-control the strong branches, control the strong and retain the weak, adjust the balance of the tree situation, and master the principles of strong side strike, heavy pruning of strong branches, light pruning of weak branches and more twigs, so as to achieve the pruning purpose of highlighting the trunk and promoting the growth of trees.

2. Pruning height: the pruning cut of the rubber tree should be smooth and the wall crack should be strictly prevented. The suitable height of stubble is 1 cm to 2 cm. Too high and too low will affect wound healing and tree growth. The suitable pruning season for rubber trees is early spring or late autumn and winter. It is suitable for early spring before the sap flows. If the tree is pruned when it sprouts, the water transpiration is fast, the water is lost, and a lot of nutrients are consumed, which is not conducive to the growth of the tree. If the rubber tree is pruned in summer, be careful not to prune on cloudy and rainy days, so as not to soak the wound and become infected with diseases.

3. Pruning techniques: in the shaping and pruning of rubber trees, it is sometimes necessary to highlight the growth of the trunk or main branches, remove the branches that are too dense or affect the shaping of the branches, and the common methods of pruning the main branches are wiping buds and thinning branches. To erase the budding buds, to achieve the purpose of inhibiting the growth of lateral branches, the principle is to eliminate the growth of lateral branches in the budding state, so that nutrients are concentrated to supply the growth of main branches. That is, the branches are cut off from the base of the branches with shears, which are often used to remove overdense branches, and thinning is a remedial measure for wiping buds, that is, because the buds are not wiped in time, lateral branches have been formed, and some redundant lateral branches are removed in order to strengthen the growth or modeling of the trunk.

4. Pruning and maintenance: after pruning, in order to prevent excessive loss of cut milk and affect survival, the wound should be smeared with plant ash in time. The treated cuttings are cut in the bed with river sand or vermiculite as the matrix, keep the bed with high humidity after cutting, and often sprinkle water to the ground (but not stagnant water) to improve the air humidity. Under the condition of 18-25 ℃ and semi-overcast, it can take root after about 2-3 weeks.

Four seasons management of rubber tree

1. Spring management: change the basin when the temperature is about 15 ℃ in spring every year, and trim it properly before changing the basin. Spring should be arranged in places with light, keep the basin soil moist, and often spray water around it to increase air humidity. Young plants can begin to apply fertilizer after seeing the emergence of new leaves. When the temperature is high at the end of spring, move it to the indoor layout and cultivation under half-light or scattered light.

2. Summer management: rubber trees are resistant to high temperature and hot sun, but when the light is too strong, the leaf color is easy to lose luster, which is not conducive to ornamental. The rubber tree cloth can be placed in a brightly lit place indoors. The room with weak light is not good for its growth. Because the rubber tree has many and large leaves and large water consumption, it should be watered in time to keep the basin soil moist, and spray more to its leaves and all around to meet its requirements for air humidity.

3. Autumn management: in autumn, the potted plants should be moved to the lighted windowsill or balcony to keep the basin soil moist. When the temperature is high at noon, spray water and spray on the surrounding and leaves to increase air humidity. In order to enhance its cold resistance in autumn, it can exercise in outdoor low temperature for a period of time, but it can not be hit by frost. People should move indoor with light in time before frosting.

4. Winter management: rubber tree is not cold-resistant and can withstand low temperature of 0 ℃ for a short time. But the indoor temperature should be kept at about 5 ℃, when the growth of rubber tree is stagnant, sufficient light should be ensured to make the basin soil moist and dry, and the basin soil is too wet and easy to rot roots. When the temperature is high at noon, spray water and spray on its surrounding and leaves for several times. When the indoor temperature is kept above 15 ℃, the rubber tree can grow normally.
