As living standards improve, the art of bonsai is gradually entering thousands of households. The elm bonsai, with its unique tree shape, beautiful posture, and strong adaptability, has become the preferred choice for many bonsai enthusiasts. Fertilization is an important part of maintaining elm bonsai. Proper fertilization not only promotes the growth of elm trees but also enhances their ornamental value. What is the best season for fertilizing elm bonsai? What are the key points of fertilization that need attention?
Best Season for Fertilizing Elm Bonsai1. Spring: Spring is the peak growing season for elm bonsai. As temperatures gradually warm up and trees begin to bud, elm trees require a higher amount of nutrients during this period. Therefore, spring is the best time for fertilization.
2. Summer: In summer, with higher temperatures, elm trees grow faster. Fertilizing at this time can replenish the nutrients consumed by trees in high temperatures and enhance their disease resistance.
3. Autumn: In autumn, temperatures gradually decrease, and elm trees begin to enter a dormant period. Fertilizing appropriately during this period can help trees accumulate nutrients, preparing for the next year's growth.
4. Winter: In winter, temperatures are low, and elm trees grow slowly. It is generally not recommended to fertilize during this period. However, if trees are transplanted or pruned in winter, a small amount of slow-release fertilizer can be applied to promote tree recovery.
Key Points of Fertilizing Elm Bonsai1. Fertilization Amount: The amount of fertilization should be adjusted according to the growth stage of the elm, soil fertility, and climatic conditions. Generally speaking, more fertilizer is applied during the vigorous growth period, and less during the dormant period.
2. Fertilization Method: There are mainly two methods of fertilization: base fertilizer and topdressing. Base fertilizer is applied in spring, primarily composed of organic fertilizers such as chicken manure and cow dung. Topdressing is applied according to the tree's growth condition, with a moderate amount of compound fertilizer or urea during the vigorous growth period.
3. Fertilization Time: Fertilization should be carried out during the elm's vigorous growth period, which is spring and summer. Fertilization in autumn should be done before trees enter the dormant period.
4. Fertilization Interval: The interval between fertilizations should be adjusted according to the growth rate of the elm and soil fertility. Generally, fertilization is done once a week during the vigorous growth period and once a month during the slow growth period.
5. Precautions for Fertilization: When fertilizing, care should be taken to avoid direct contact between fertilizer and leaves and stems to prevent leaf and root burns. After fertilization, water should be provided promptly to dissolve the fertilizer thoroughly.
