There are often some pyracantha, Vitex negundo, elm and so on. In the wild mountainous areas, there are often many thick stumps. After digging back, after a period of composting, it was planted in pots and gradually processed into exquisite bonsai. The following is a brief introduction to the basin and daily maintenance methods of pyracantha, hoping to provide some help to bonsai lovers.
1, culture soil requirements
Pyracantha fortuneana has strong adaptability to the environment and can be planted in early spring or autumn. Generally, after digging back, you have to raise piles for one year before you can go to the basin for maintenance. The culture soil in the upper basin of pyracantha fortuneana should be loose, fertile, breathable and well drained. When preparing the culture soil, 4 parts of humus soil, 3 parts of garden soil, 2 parts of coarse sand and compost 1 part can be used, and then mixed evenly to make the culture soil planted with pyracantha fortuneana.
2. Basin method
When pyracantha is piled up and planted in a pot again, a suitable flowerpot should be selected according to the plant size, and the drainage hole at the bottom of the pot should be padded with gauze or ceramic tile to drain away excess water. Fill a layer of cinder or coarse sand as drainage layer, and then fill a part of culture soil. Adjust the plants to fill in the position, and compact the surrounding soil at the same time, so that the roots are closely combined with the culture soil. After planting, water it once and put it in a cool and ventilated place to slow down the seedlings.
3. Fertilization management
After the pyracantha is newly planted in the pot, fertilization is not needed for the time being. After three months, topdressing can be applied in the growing period to promote the development of growing plants, and fermented cake fertilizer or compound fertilizer can be applied once every half month. Before plants bloom, it is necessary to ensure adequate phosphorus and potassium fertilizer, which can promote plants to blossom and bear fruit and make plants bear more fruits. Before flowering, dilute potassium dihydrogen phosphate aqueous solution can be poured every 10 day, and fermented organic fertilizers such as chicken manure and bone meal can also be applied to the pot soil at ordinary times, which can increase the fruit-setting ability of the plant and make the fruit redder when it matures.
4, watering requirements
Pyracantha thrives. In order to make plants grow well, their growth needs to keep enough water, and the basin soil should not be too dry. Especially in the flowering and fruiting period, if the soil in the basin is too dry, it will drop flowers and fruits. Usually watering can be "dry", but also to avoid the formation of water in the basin, otherwise it will easily lead to root rot, and the soil in the basin is too wet and easy to lose flowers and fruits. In summer, water evaporates quickly, and the basin soil is easy to dry, so it is necessary to replenish water at any time. When plants enter dormancy in winter, the water demand is reduced, so watering can be reduced and the soil can be kept slightly wet and dry.
5. Dressing and shaping
The branches and leaves of Pyracantha fortuneana grow rapidly, and if they are not pruned, it is easy to lose their original tree shape. Therefore, we should always trim and reshape the branches and leaves that are too messy. During the growing period of plants, you can sparse the dense branches, cut off the dead branches and diseased branches, and properly remove the messy branches at any time, which can not only reduce the consumption of nutrients, but also increase the ventilation and light transmission of plants and make the plant look more beautiful.
6. Lighting requirements
In the maintenance process of pyracantha fortuneana, it is necessary to ensure sufficient light time. Only under the condition of sufficient light can the plants flourish and complete flowering and fruiting. If there is a long-term lack of sunshine, plants will grow branches and leaves in vain, which will affect normal flowering and fruiting. Therefore, pyracantha should be kept in sunny places at ordinary times.
When digging pyracantha fortunei for bonsai in the field, it is best to raise piles with pure river sand first, and then go up after the plants sprout new roots and survive completely.
