Method of Cultivating Ziziphus xylopyrus Bonsai
This article introduces the cultivation method of Ziziphus xylopyrus bonsai, as well as the management and care knowledge related to Ziziphus xylopyrus flowers. The following is a detailed introduction.
Ziziphus xylopyrus is a precious tree species, which is suitable for garden and courtyard decoration as a bonsai, possessing very high ornamental value. It has strong adaptability, and daily maintenance is not only beneficial for plant growth but also for shaping the bonsai. Let's talk about what to pay attention to in the maintenance of Ziziphus xylopyrus bonsai and how to do it.
I. Growing Environment
1. Temperature
Ziziphus xylopyrus is cold and heat resistant, with a high-temperature tolerance limit of up to 43°C and a low-temperature tolerance of minus 21 degrees Celsius. No cooling is required in summer, and no indoor cultivation is needed in winter. However, attention should be paid to the water temperature for watering. If the water temperature is too low during high summer temperatures, it can cause leaf wilt, and the same is true in winter. The water temperature should be close to the air temperature before watering.
2. Water
Ensure not to water when the soil is dry, and the potting soil should only be slightly moist. Watering can be done by pouring water close to the edge of the pot, then watering again after the surface water has渗透. Watering is best done at 8 or 9 am, preferably not at night. Accumulated water should be removed on rainy days.
Water once every 3 to 4 days in spring and autumn, once a day in the morning or evening during the cooler summer months, increasing the amount of water, and once a week in winter. Since different pots have different drainage and aeration, actual operations should depend on the dryness of the potting soil. River, well, or rainwater is best for watering, and washing rice water can also be used, but the water quality should be free of contamination.
3. Light
Ziziphus xylopyrus enjoys light and is somewhat shade-tolerant. Growth is better in sufficient sunlight, and when new branches are robust and new leaves are purplish-red, it indicates that the plant has adequate water, fertilizer, and light; otherwise, it is insufficient.
4. Pot and Soil
After the pot plant is formed, the soil can be reduced by half and then filled with coal slag.
5. Fertilizing
No need for too much fertilizer. Before the plant forms a tree shape, apply thin fertilizer frequently, once every 5 to 7 days, choosing a sunny afternoon in spring and summer. After the tree shape is formed, fertilizing can be stopped.
II. Maintenance
1. Pruning and Bonsai Shaping
To maintain the shape of the bonsai, it is necessary to prune the plant appropriately. Spring and autumn are the growing seasons, during which new buds of Ziziphus xylopyrus can be pinched off, and prominent long branches can be cut to maintain the shape of the pot plant. In late August, after a brief dormant period, the new buds of Ziziphus xylopyrus should also be pinched off.
Newly purchased plants need to be modified, mainly by pruning the trunk to promote shaping of the plant, cutting off unnecessary roots and branches, and paying attention to treating wounds after pruning. A healing agent can be applied to promote wound healing and avoid infection by diseases and pests. To maintain the shape of the pot plant, pruning should focus on thinning the branches and changing the frog leg branches to hanging拐.
2. Pot and Soil Replacement
Young plants need to replace the potting soil according to the size of the plant, and mature plants generally need to replace the potting soil every 2 to 3 years.
III. Diseases and Pests
Ziziphus xylopyrus has very strong disease resistance, but if the potting soil is too alkaline or if tap water is used for a long time, it can cause chlorosis, which requires preventive measures. Use a 400-fold dilution of ferrous sulfate solution to water the roots once a week, for 3 to 5 consecutive weeks.
The common pest is the flower thrips. Once detected, it can be controlled with pesticides such as a 800-fold dilution of敌杀死. Cottony cushion scale and red wax scale often appear on trees that are not growing well, mainly in early summer and autumn. These pests can be killed by spraying a 20% dilution of fenvalerate 2000.
