Ziziphusjujuba var. spinosa 'Duijie Bai蜡' is a valuable tree species, suitable for landscape and courtyard decoration as a bonsai, with 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 needs to be paid attention to in the maintenance of Ziziphusjujuba var. spinosa 'Duijie Bai蜡' bonsai and how to do it.
I. Growing Environment
1. Temperature
Ziziphusjujuba var. spinosa 'Duijie Bai蜡' is cold and heat resistant, with a high-temperature tolerance limit of 43℃ and a low-temperature tolerance of -21℃. It does not need to be cooled in summer or moved indoors for cultivation 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 applies in winter. The water temperature should be close to the air temperature before watering.
2. Water
Ensure that the soil is not dry and only slightly moist. When watering, first pour water close to the edge of the pot, and then pour again after the water on the surface has seeped down. It is best to water in the morning at 8 or 9 o'clock, and avoid doing so at night. Accumulated water should be cleared during rainy days.
Water every 3 to 4 days in spring and autumn, water once a day in the morning or evening during the cooler summer months, and increase the amount of water. In winter, water once a week. Due to different pot drainage and aeration, actual operations should be based on the dryness of the soil. River, well, or rainwater is best for watering, and washing water can also be used, but the water quality should not be polluted.
3. Light
Ziziphusjujuba var. spinosa 'Duijie Bai蜡' loves light and is somewhat shade-tolerant. Growth is better under sufficient sunlight. When new branches are robust and new leaves are purplish-red, it indicates that the plant has sufficient water, fertilizer, and light, otherwise it is insufficient.
4. Pot and Soil
After the bonsai is formed, the soil can be halved and then filled with coal slag.
5. Fertilization
No need for too much fertilizer. Before the plant forms a tree shape, apply thin fertilizer frequently, once every 5 to 7 days, choosing sunny afternoons in spring and summer. After the tree shape is formed, fertilization can be stopped.
II. Maintenance
1. Pruning and Bonsai Shaping
To maintain the shape of the bonsai, the plant needs to be pruned appropriately. Spring and autumn are the growing seasons when new buds of Ziziphusjujuba var. spinosa 'Duijie Bai蜡' can be pinched off, and prominent long branches can be cut to maintain the shape of the bonsai. In late August, after a brief dormant period, new buds of Ziziphusjujuba var. spinosa 'Duijie Bai蜡' should also be pinched off.
Newly purchased plants need to be modified, mainly by pruning the trunk to encourage shaping, 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 prevent disease and pest infections. To maintain the shape of the bonsai, pruning should focus on thinning the branches and changing the "frog leg" branches to hanging拐 branches.
2. Potting and Soil Replacement
Young plants need to replace the potting soil according to their size, and mature plants generally need to replace the potting soil every 2 to 3 years.
III. Diseases and Pests
Ziziphusjujuba var. spinosa 'Duijie Bai蜡' has very strong disease resistance, but if the soil is too alkaline or tap water is used for a long time, it can cause chlorosis, requiring preventive measures. Use a 400-fold dilution of ferrous sulfate solution to water the roots once a week for 3 to 5 times.
Common pests are flower thrips, which can be controlled with 800-fold dilution of "敌杀死" liquid or other pesticides. Cottony cushion scale and red wax scale often appear on trees with poor growth, usually occurring in early summer and autumn. They can be killed by spraying a 20% cypermethrin solution diluted 2000 times.
