Culture methods and matters needing attention of bamboo begonia

Bamboo begonia is a perennial herb of the genus Begonia of the family Begonia. It is native to Brazil. It is cultivated in parks and flower beds in Haikou and Guangzhou, China, with high ornamental value, flower shape and soft leaf color. Potted plants are often used to decorate living rooms, shop windows or decorate family windowsills, balconies, coffee tables and other places. Let's take a look at the breeding methods and matters needing attention of bamboo crabapple.

Propagation methods of Bamboo Begonia

1. Sowing: the common introduction, variety improvement and large-scale commercial production of bamboo crabapple at home and abroad can be carried out indoors or in greenhouse, and the conventional introduction should be from April to May in spring or September to October in autumn. Because the seeds are very small, you need to be careful when sowing.

2. Cuttage: bamboo crabapple can be cut by stem, leaf and rhizome.

① stem cuttings: the stem propagation of bamboo crabapple can be carried out all the year round at room temperature, but the best effect is from April to May, with fast rooting and high survival rate. The sturdy top of the stem is often selected as cuttings, and it generally heals and takes root in 9-27 days after insertion.

② leaf insertion: the effect of leaf insertion propagation of bamboo crabapple is the best in summer and autumn. It can be cultivated at room temperature and can also be carried out in winter, but the rooting is slow. For example, in the process of cutting, rooting will be delayed when the soil temperature is lower than 15 ℃, but it is difficult to take root when it is lower than 10 ℃.

③ root insertion: in spring and autumn, bamboo crabapple cut the lower rhizome into 3 cm oblique cutting or flat on the sand bed, keeping room temperature 20: 22 ℃, generally growing adventitious roots 15-20 days after insertion, and sprouting adventitious buds in 30-40 days.

Planting method of Bamboo Begonia

1. Soil: bamboo crabapple culture soil is made of compost soil, rotten leaf soil and charcoal soil. Alkaline or clayey and easy-hardened soil is not conducive to the growth of new roots, which can easily lead to short stems and leaves, dim color, and yellowing disease.

2. Temperature: the bamboo crabapple grows rapidly in the warm environment, the stems and leaves are luxuriant, the flowers are bright, the suitable temperature for growth is 19: 24 ℃, and the winter temperature is not lower than 10 ℃, otherwise the leaves are easy to freeze, but the roots are more resistant to cold.

3. Watering: bamboo crabapple likes semi-shady, mild and humid environment, has strong drought resistance, but is afraid of waterlogging, so watering should be dry and wet, and it is best to keep the basin soil moist. It is necessary to spray water on the leaf surface and the ground in the middle of summer.

4. Fertilization: bamboo crabapple likes fertilizer, and fertilization should be carried out by hoeing when the basin soil is dry. Watering after fertilization can facilitate plant absorption. Dilute liquid fertilizer is applied every 10 to 15 days in spring, and fertilization should be reduced in high temperature season in summer. Fertilization should be suspended during flowering and winter.

5. Lighting: bamboo begonia likes shade and is afraid of exposure, so it is suitable for cultivation in Nanyang platform all the year round. It should be given sufficient sunlight in spring, autumn and winter, and avoid strong light in summer, otherwise it will make the plant leaves yellowing and grow slowly.

6. Pruning: bamboo knots grow vigorously in the autumn sea, and the plants that have been growing for many years or the leaves at the lower part of the stem are not beautiful, which can be pruned in combination with changing pots in spring to facilitate the sprouting of new branches.

Control of Diseases and insect pests of Bamboo Begonia

1. Leaf spot: try to avoid infecting germs when cutting propagation, and destroy diseased plants in time after finding diseased plants. To minimize the use of irrigation at the top of the plant will also inhibit the occurrence and spread of the disease, and slightly reducing the concentration of feed can also reduce the occurrence of the disease.

2. Botrytis cinerea: controlling the spread of Botrytis cinerea fungi in winter months has become an important part of cultivation management, and the important way to reduce ash occurrence and diffusion is to accelerate the drying of leaves and reduce the air humidity in the greenhouse.

3. Root rot: disinfecting the upper basin substrate and planting bed before and after planting with fungicides can well control the root rot caused by rot mold, and reduce the amount of irrigation as much as possible to reduce the occurrence of root rot and promote root growth.

4, sudden collapse disease: after the onset of the disease, there are brown mildew attached to the disease, standing withered silk color is often reddish brown, shaped like cobwebs, can be controlled by spraying different fungicides, most of which are irrigated by soil.

5. Fusarium wilt: there are waterlogged disease spots where the stem is in contact with the medium, which can easily lead to cuttings rot if the plant is infected. All infected plants and containers should be removed from the planting area and destroyed as soon as possible.

Matters needing attention of bamboo begonia

1. When the bamboo crabapple changes the basin or the stems and leaves are not strong, do not apply big fertilizer, otherwise it will burn roots, and thin liquid fertilizer can be applied every two weeks during the peak growth period.

2. After growing for many years, the leaves at the bottom of bamboo crabapple will turn yellow and fall off, which will affect the appearance of the plant, so it can be pruned when changing pots in spring.

3. Bamboo crabapple likes sufficient scattered light in summer, and at high temperature, if the light is too strong, it is easy to cause the leaf dry tip scorched edge, leaf yellowing and even fallen leaves.

4. Placing the bamboo crabapple in the dark in summer will not only reduce the number of leaves and flowers, but also cause the plant to grow too much.

5. Bamboo crabapple should not only keep the basin soil moist and not too wet in summer, but also avoid stagnant water in the basin, otherwise it will cause retting root and die.

6. Bamboo crabapple will appear diseases and insect pests in the growth process, which should give priority to prevention and comprehensive control, such as early prevention and control.
