Rosemary Bonsai
Rosemary Bonsai, with its unique woody branches and aromatic characteristics, has become a popular choice for home greenery. This plant, which combines ornamental and practical values, can present an elegant tree shape through scientific care. This article will systematically analyze the secrets of making it from basic care to advanced shaping.
Key Points of Rosemary Bonsai Care
Environmental Control and Substrate Selection
Use a breathable red pottery pot with sandy loam soil (perlite: peat soil = 3:7) to ensure 6 hours of scattered light daily. Keep above 10℃ in winter and avoid direct sunlight in summer, and rotate the pot to ensure even light exposure.
Water and Fertilizer Management Cycle
Water twice a week in spring and autumn, increase to three times in summer, using the pot immersion method to avoid water accumulation on the leaves. Apply diluted kelp fertilizer monthly during the growing season, and apply phosphorus and potassium fertilizer after flowering to promote lignification.
Advanced Techniques for Shaping Rosemary Bonsai
Pruning Time and Method
Perform heavy pruning every March to April, leaving the trunk 15cm, and cut diagonally at 45° to promote lateral buds. During routine maintenance, remove inner branches and pinch the top of the long branches, combined with aluminum wire coiling to create a curved trunk shape.
Accelerated Lignification Plan
By controlling water stress (letting the potting soil dry to white before watering) to stimulate the plant's defense mechanism, and using high-potassium fertilizer, the stem can complete the basic lignification transformation in 3 months.
Disease and Pest Control and Shape Maintenance

Regularly spray neem oil to prevent red spider mites and maintain good ventilation to avoid powdery mildew. When repotting the mature bonsai every spring, use a bamboo stick to remove 1/3 of the compacted old soil and replenish new substrate to maintain vitality.
Through continuous pruning and shaping for 3-5 years, classic bonsai shapes such as cliff and literati trees can be cultivated. Regularly taking growth records and comparing the morphological changes at different stages can further enhance the enjoyment of shaping and cultivating.
