Osmanthus, also known as the sweet olive tree, is a traditional and valuable ornamental plant in China. Its flowers have a strong fragrance and are known as "the messengers of autumn." To ensure the robust growth of osmanthus trees, a proper fertilizing method is crucial. This article will provide a detailed introduction to the fertilization methods of osmanthus trees to help you care for them beautifully.
Principles of Fertilizing Osmanthus Trees1. Moderate Fertilization: Excessive fertilization can lead to excessive growth of the osmanthus tree, affecting its ornamental value; insufficient fertilization will affect the growth and development of the tree.
2. Staged Fertilization: Distribute the amount of fertilizer according to the growth cycle of the osmanthus tree.
3. Application of Organic Fertilizer: Organic fertilizers are beneficial for improving soil structure and increasing soil fertility.
Methods of Fertilizing Osmanthus Trees1. Spring Fertilization
Spring is a critical period for the growth of osmanthus trees. Fertilization at this time should focus on nitrogen to promote the growth of branches and leaves. Specific methods are as follows:
(1) Before the osmanthus tree sprouts, apply decomposed organic fertilizer such as chicken manure or cow dung, with an amount of about 2-3 kilograms per tree.
(2) After the osmanthus tree has sprouted, apply urea or compound fertilizer, with an amount of about 100-150 grams per tree.
2. Summer Fertilization
In summer, with high temperatures, the osmanthus tree grows vigorously. Fertilization at this time should focus on phosphorus and potassium to promote the formation of flower buds. Specific methods are as follows:
(1) Before the osmanthus tree forms flower buds, apply monoammonium phosphate or calcium superphosphate, with an amount of about 100-150 grams per tree.
(2) After the osmanthus tree has formed flower buds, apply potassium sulfate or wood ash, with an amount of about 100-150 grams per tree.
3. Autumn Fertilization
Autumn is a period of vigorous growth for osmanthus trees. Fertilization at this time should focus on potassium to enhance the cold resistance of the tree. Specific methods are as follows:
(1) Before the osmanthus tree sheds its leaves, apply wood ash or potassium sulfate, with an amount of about 200-300 grams per tree.
(2) After the osmanthus tree has shed its leaves, apply decomposed organic fertilizer such as chicken manure or cow dung, with an amount of about 2-3 kilograms per tree.
4. Winter Fertilization
In winter, the osmanthus tree grows slowly. Fertilization at this time should focus on organic fertilizers to improve soil fertility. Specific methods are as follows:
(1) During the dormancy period of the osmanthus tree, apply decomposed organic fertilizer such as chicken manure or cow dung, with an amount of about 2-3 kilograms per tree.
(2) After the dormancy period of the osmanthus tree, apply urea or compound fertilizer, with an amount of about 100-150 grams per tree.
Precautions for Fertilizing Osmanthus Trees1. Avoid direct contact between fertilizer and the roots of the osmanthus tree to prevent root burning.
2. After fertilizing, water promptly to dissolve the fertilizer thoroughly, making it easier for the osmanthus tree to absorb.
3. Regularly check soil fertility and adjust the amount of fertilizer based on the condition of the soil.
Proper fertilization is key to the healthy growth of osmanthus trees. With the introduction of this article, it is believed that you have mastered the fertilization methods of osmanthus trees. By following scientific fertilization principles and fertilizing reasonably, your osmanthus trees will surely grow robustly and add a beautiful landscape to your home.
