Pruning method of begonia bonsai
1, basin selection:
Begonia bonsai generally uses deep rectangular or oval pots, square and round pots, and deep cliff pots. The texture is suitable for purple sand pottery basin or glazed tile pottery basin, because this basin is permeable and breathable.
2, with soil:
The requirements for soil quality are not strict, and it can be slightly acidic soil or neutral soil, but loose and fertile humus soil or pastoral soil with good drainage is preferred. When placing the basin, the bottom of the basin should be padded with sand or vermiculite to facilitate drainage.
3. Planting:
It can be used in spring and autumn, and the dormancy period is suitable. Be sure to cut short thick roots and long roots before planting to avoid bending in the basin. After planting, water it, put it in a cool place 1 ~ 2 weeks, and then move it to a place with sufficient light.
4, trim modeling:
Begonia has strong germination and rapid progress. It needs a touch-up. After defoliation in summer and before germination in spring, dead branches, diseased branches, twigs, cross branches, overlapping branches and over-dense branches can be cut off. After flowering in spring, we can shorten the long branches, promote the lateral branches and increase the number of flower buds according to the appearance requirements.
Begonia bonsai can be shaped by climbing silk. Due to the rapid growth of begonia, attention should be paid to removing brown silk or metal wire in time to prevent? Trapped wires? . The modeling period should be carried out after flowering or dormancy.
The tree shape of begonia bonsai is mostly inclined, curved or cliff-shaped. What needs to be emphasized is that its branches are strong and flexible. The scene of an old pile with oblique branches and bright colors is the most interesting.
Cultivation method of begonia bonsai
1, water and fertilize. It is advisable to keep the basin soil moist when watering. In dry and midsummer weather, it is necessary to spray water on leaves and ground, and improving air humidity is beneficial to growth. Avoid water and rain in the basin, otherwise the roots will rot easily. Potted soil should be slightly dry in winter, and clean water should be sprayed on leaves and environment every 7 days, which not only increases humidity but also makes leaves clean. Apply 1 times pancake fertilizer and water for about 10 days during the growth period; Topdressing available phosphate fertilizer in bud stage. When applying fertilizer, be careful not to splash the fertilizer solution on the leaves; Flowering and winter and summer are not suitable for fertilization.
2. Light and temperature. The suitable temperature for the growth of begonia is 18~20℃, which has good ventilation and scattered light environment. Measures such as shading, ventilation and watering should be taken in high temperature season; It is best to keep the room temperature above 10℃ in winter, and it can be placed in a sunny place. When raised at home, it should be placed in outdoor scattered light 1~2 times a week during the growing season, and in sunny places in winter.
3. Tie it up and turn the basin over. Because the plants of Begonia are relatively tall, it is necessary to use thin bamboo poles and other things to support the branches to prevent lodging. At the same time, turn over pots, change soil, prune branches and cut off weak branches, overlapping branches and residual roots every spring. Plants that have been flowering for 2~3 years and are too high should be cut short, leaving only 6~ 10 cm for new shoots to sprout again.
Cultivation points of begonia bonsai
In a sunny place, begonia likes sunshine and is not tolerant of shade. Keep it in a place where the sun can shine, and it is easy to grow in a cool place. However, if the sun at noon in summer is poisonous, we should give some shelter to avoid burning flowers and leaves.
The soil should be loose and alkaline. Begonia flowers need loose soil, which contains a certain alkalinity, and the ph value of the soil should not be lower than 7. You can choose the soil at the bottom of flower beds or tree roots and add one third of river sand.
The planting depth should not be too deep, and the planting depth of begonia flowers in the pot should not be too deep, so that the roots can be better stretched. It is best to install it at a depth of 12 cm from the bottom of the pot, but it depends on the size of the plant.
It is best to keep the basin soil moist when watering. The specific watering depends on the weather. The basin soil should be kept moist, but water is not allowed. It is best not to get wet in the rain, lest too much water lead to rotten roots. Don't water it when it is too cold.
Fertilize in time, apply some organic fertilizer to supplement nutrients when spring buds germinate, and water them once. When the leaves fall in autumn, apply organic fertilizer and water them once. After the flowers wither, apply phosphorus and potassium fertilizer. You can buy some special fertilizer for begonia every day and fertilize it properly according to the instructions.
If you want to put it in a ventilated place, you can put it in a ventilated place such as a courtyard or balcony. Begonia is cold-resistant, so it can also be placed outdoors in winter, but if it is particularly cold, some anti-freezing measures are still needed.
Pruning branches and leaves in early spring, in order to ensure that plants can bloom vigorously, pruning should be carried out from the time when begonia leaves fall to the time when it germinates in early spring. Weak branches, pests and diseases, individual long branches and over-dense branches can be subtracted, and the sparse parts of branches can also be cut vertically to promote more side branches.
