This article will provide a detailed analysis of the fertilization techniques for elm bonsai every year, helping you maintain a healthy and beautiful elm bonsai.
Spring fertilizationSpring is the season when elm bonsai grows vigorously. Fertilization at this time should focus on nitrogenous fertilizers to promote the growth of new branches and leaves. Specific fertilization methods are as follows:
1. Choose suitable nitrogenous fertilizer: There are many types of nitrogenous fertilizers suitable for bonsai, such as urea and ammonium sulfate. It is recommended to choose non-irritating, easily soluble nitrogenous fertilizers.
2. Fertilization time: Spring fertilization is generally carried out in March to April, when elm bonsai begins to germinate, which is a good time for fertilization.
3. Fertilization amount: Depending on the size and growth condition of the elm bonsai, fertilize every 10-15 days, with each fertilization amount being 1%-2% of the total weight of the bonsai.
4. Fertilization method: Spread the nitrogenous fertilizer evenly on the pot surface, then cover it with fine soil to avoid direct contact between the fertilizer and the leaves.
Summer fertilizationIn summer, the temperature is high, and the growth rate of elm bonsai accelerates. At this time, fertilization should focus on phosphorus and potassium fertilizers to strengthen the tree's vitality. Specific fertilization methods are as follows:
1. Choose suitable phosphorus and potassium fertilizers: Such as monopotassium phosphate and potassium sulfate, which help to improve the disease resistance and ornamental value of elm bonsai.
2. Fertilization time: Summer fertilization is generally carried out in May to July, when elm bonsai enters the period of vigorous growth.
3. Fertilization amount: Fertilize every 10-15 days, with each fertilization amount being 0.5%-1% of the total weight of the bonsai.
4. Fertilization method: Spread the phosphorus and potassium fertilizers evenly on the pot surface, then cover them with fine soil.
Autumn fertilizationIn autumn, the temperature gradually decreases, and the growth rate of elm bonsai slows down. At this time, fertilization should focus on potassium fertilizers to promote lignification of branches. Specific fertilization methods are as follows:
1. Choose suitable potassium fertilizers: Such as potassium sulfate and potassium chloride, which help to improve the cold resistance of elm bonsai.
2. Fertilization time: Autumn fertilization is generally carried out in August to September, when elm bonsai begins to enter the dormant period.
3. Fertilization amount: Fertilize every 10-15 days, with each fertilization amount being 0.5%-1% of the total weight of the bonsai.
4. Fertilization method: Spread the potassium fertilizer evenly on the pot surface, then cover it with fine soil.
Winter fertilizationIn winter, the temperature is low, and the growth of elm bonsai is slow. At this time, fertilization should focus on organic fertilizers to supplement nutrition. Specific fertilization methods are as follows:
1. Choose suitable organic fertilizers: Such as chicken manure and cow dung, which are rich in various nutrient elements and help to improve the disease resistance and ornamental value of elm bonsai.
2. Fertilization time: Winter fertilization is generally carried out in November to December, when elm bonsai begins to enter the dormant period.
3. Fertilization amount: Fertilize every 20-30 days, with each fertilization amount being 1%-2% of the total weight of the bonsai.
4. Fertilization method: Spread the organic fertilizer evenly on the pot surface, then cover it with fine soil.
