Bonsai is a unique and ancient art form that involves cultivating and pruning small plants to shape them into various forms of landscapes found in nature. Bonsai trees are the quintessence of this art form. Bonsai trees come in a rich variety of species and diverse shapes, and their branches, leaves, flowers, and fruits possess the same vitality and charm as natural trees. As a crucial part of bonsai tree care, fertilizer provides the necessary nutrients and elements for growth. Therefore, selecting the right fertilizer is vital for the healthy growth of bonsai trees.
I. Understand the Care Needs of Bonsai Trees
As artificially cultivated plants, bonsai trees have high requirements for growth environments, temperature, humidity, and other factors. The nutrients they require also differ from those of trees growing in the wild. Therefore, when choosing fertilizer, it is necessary to first understand the care needs of the bonsai tree, including its species, cultivation method, soil type, and seasonal changes.
II. Choose the Right Fertilizer Based on the Bonsai Tree's Growth Cycle
The growth cycle of a bonsai tree can be divided into the growth period, dormancy period, and flowering/fruiting period. The nutrient requirements of bonsai trees differ during these various cycles. Therefore, when selecting fertilizer, it needs to be adjusted according to the bonsai tree's growth stage to meet its needs.
III. Understand the Composition and Application Scope of Different Types of Fertilizers
The composition and application scope of fertilizer are crucial for selection. Commonly available fertilizers on the market include organic, chemical, and compound fertilizers. They contain different nutrient components and have different application scopes. Therefore, it is necessary to select a suitable fertilizer based on the bonsai tree's species and care needs.
IV. Choosing Natural Organic Fertilizers Can Reduce Pollution Risks
Natural organic fertilizers are mainly derived from natural products such as animal and plant residues and compost. They are rich in organic matter and trace elements, which can improve the soil environment and increase water retention. This not only aids in the growth of bonsai trees but also reduces the risk of pollution.
V. Compound Fertilizers Can Improve Nutrient Absorption Efficiency in Bonsai Trees
Compound fertilizers contain multiple elements and components that can meet the needs of bonsai trees at different growth stages. The proportions of elements like nitrogen, phosphorus, and potassium are well-balanced, which can enhance the nutrient absorption efficiency and disease resistance of bonsai trees.
VI. Avoid the Hazards Caused by Excessive Fertilizer Use
Excessive use of fertilizer can cause bonsai tree leaves to turn yellow, wilt, or even die, and can lead to hazards such as groundwater pollution. Therefore, when fertilizing, the amount must be appropriate; overuse should be avoided.
VII. Appropriate Use of Nitrogen Fertilizer Can Promote the Growth of Bonsai Trees
Nitrogen is one of the essential elements for plant growth. The appropriate use of nitrogen fertilizer can promote the growth of bonsai trees, increasing the number and size of leaves and branches. However, it is important to use it in moderation, as excessive nitrogen fertilizer can instead cause the bonsai tree to wither.
VIII. Phosphorus Fertilizer Can Promote Flower and Fruit Growth
Phosphorus is one of the important elements that promote plant flowering and fruiting. The appropriate use of phosphorus fertilizer can promote the growth and development of flowers and fruits on bonsai trees. However, attention must be paid to controlling the amount, as excessive use can lead to an increase in pests and diseases.
IX. Potassium Fertilizer Can Improve the Resistance of Bonsai Trees
Potassium is one of the essential elements for plant growth and can improve the resistance of bonsai trees, enhancing their ability to withstand adverse conditions. The appropriate use of potassium fertilizer can promote the growth and development of bonsai trees, but attention must also be paid to controlling the amount.
X. The Timing of Top-Dressing Should Be Appropriate
Top-dressing is an important part of bonsai tree care, but timing is crucial. Generally, it is best to apply top-dressing during the bonsai tree's growth period, allowing the plant to receive sufficient nutrients during its peak growth season.
XI. The Combination of Fertilizer and Water Also Needs Attention
The relationship between water and fertilizer is also very important. Bonsai trees require a large amount of water. Excessive fertilizer can be lost along with water, leading to dehydration and death of the bonsai tree. Therefore, when fertilizing, it is necessary to appropriately reduce the amount of watering to ensure the normal growth of the bonsai tree.
XII. Pay Attention to Quality When Choosing Fertilizer
The market offers various brands and qualities of fertilizers. It is important to choose well-known brands and reliable quality fertilizers to avoid unnecessary damage to the bonsai tree.
XIII. The Amount of Fertilizer Applied Varies Depending on the Growth State of the Bonsai Tree
Bonsai trees in different growth states have different fertilizer needs. Therefore, when applying fertilizer, it is necessary to make appropriate adjustments based on the bonsai tree's growth state to achieve the best results.
XIV. The Frequency of Fertilizer Application Should Also Be Controlled Appropriately
The frequency of fertilizer application is also very important. Too frequent application can cause the leaves of the bonsai tree to turn yellow, and in severe cases, can lead to plant death. Therefore, it is necessary to appropriately control the application frequency based on the bonsai tree's growth state and needs.
XV.
Choosing the right fertilizer is an extremely important part of bonsai tree care. It is necessary to consider multiple factors comprehensively, including the bonsai tree's growth cycle, species characteristics, and soil environment, and use the correct fertilizer at the right time. Appropriately adjusting the application amount and frequency ensures the healthy and lush growth of the bonsai tree.
