How to treat bonsai wooden begonia with ant nest?
First, use a bucket of clear water to slowly sink the damaged bonsai or potted flowers to the bottom of the bucket (the water surface can be soaked to the top of the pot), and remove all the ants in the water for half an hour; Or peel garlic, break it into small pieces with a kitchen knife and bury it in the pot soil at equal distance. After two or three days, the ants fled, which had no effect on the growth of flowers and trees. 2. 70% mirex powder is directly sprinkled on the soil surface with ant nests, or around ant nests and ant paths, or blocked into bait. In addition, spraying powders such as lindane, chlordane and heptachlor on the soil surface with active ant colonies also has good effects.

How to raise woody begonia flowers

1. Planting is generally carried out underground, or potted plants can be made into bonsai and planted in spring. Because we want to avoid water stains, we should plant it in a place with a little higher terrain, less water accumulation and plenty of sunshine. The soil is neutral and alkaline, and the pH value is not lower than 7. The material should be loose, but not too fertile, which will easily lead to virtual length and reduced flowering period. Planting holes should be determined according to the size of the root system, not too deep or too big, and the root system should be dispersed as well. The planting depth should be10cm above the ground. It is best to plant with soil balls. After planting, pour enough water.

2. The light temperature begonia is suitable for growing in sunny environment, but it grows poorly in cool environment. If potted, put it in a well-lit place during the growing period. It will not freeze at the low temperature of-15℃ in winter, and can overwinter in the open air. But in the extremely cold winter, it is necessary to take cold-proof measures.

3. The combination of watering and fertilization. It is better to apply 1 times fertilizer after defoliation every autumn to supplement the nutrients consumed by flowers and fruits and to apply decomposed organic fertilizer. At the same time combined with winter irrigation and watering. Before shading spring buds, apply organic fertilizer 1 times and water 1 times. Fertilization methods vary with the age of trees in autumn and winter. Young trees are picked by ring and fertilized by shaking table, and the distance between ring and root is within 100 cm. Radial excavation and fertilization are carried out on the old trees; Weeds should be eliminated in the old tree combination, and organic fertilizer should be applied under the crown. After fertilization, the fertilizer should be turned into the soil for 30 cm, and phosphorus and potassium fertilizer should be applied twice after flowering to ensure a certain fruit setting rate. Pay attention to watering at the same time.

4. The flower buds of shaping and pruning begonia are mostly differentiated from terminal buds, mainly with medium and short fruit branches, which should be kept. Long branches should be cut short, and at the same time, dense branches, dead branches and insect branches should be cut off, and then pruned according to the required tree shape. In order to make the crown perfect, it is necessary to cultivate sparsely, cut off the branches that are too dense, and cut the sparse parts of the branches vertically, so as to make them have many side branches, concise and ethereal.
