Rose Bonsai Making Method
Roses, with their rich colors and elegant shapes, have become a popular choice in the art of bonsai. But how to transform ordinary roses into uniquely shaped bonsai? This not only requires mastering grafting techniques but also systematic care knowledge. We will guide you through five key steps, from selecting the stock material to pest and disease control, to fully understand the mysteries of rose bonsai shaping.
Core Shaping Techniques
Stock Material Selection and Treatment
Quality stock material is the foundation of successful rose bonsai. Select robust branches 3-5 years old with a diameter of 2-3 centimeters, and cut them before the early spring sprouts. The cut ends need to be treated with wax, leaving 3-5 plump buds. After cutting, immediately soak the stock in a rooting hormone solution for 2 hours, which can significantly improve the survival rate.
Bud Grafting Technique
When using the T-shaped bud grafting method, the scion should be taken from the current year's semi-woody branches. When cutting the bud piece, retain a 0.5 cm petiole, align the cambium layer, and wrap it with 0.04mm special grafting film. During the bagging care period, maintain humidity at 70%-80% and temperature at 22-28℃ for best results.
Systematic Care Management Plan
Shaping Pruning System
Establish a three-level pruning mechanism: the primary branches retain 3-5 main branches, the secondary branches maintain a spacing of 8-10 cm, and the tertiary branches control density through pinching. After flowering, promptly reduce the flowering branches, leaving 2-3 buds at the base. When using wire wrapping, it should be done when the branches are semi-woody, adjusting the binding angle every 15 days.
Nutrition Supply Plan
Prepare a special nutrient soil (decomposed leaf soil: vermiculite: bone meal = 5:3:2), apply 20-30 slow-release fertilizers every quarter. Alternate the use of Huaduo No. 1 (NPK 20-20-20) and No. 2 (10-30-20) water-soluble fertilizers during the growing period, and apply phosphorus potassium fertilizer before the flowering period.
Strategy for Pest and Disease Control
Establish a preventive spraying calendar: in March, clear the garden with lime sulfur, alternate the use of pymetrozine and etoxazole from April to June to control aphids and red mites, and alternate with mancozeb and benzene醚甲环唑 from July to September to prevent black spot disease. Immediately remove diseased leaves and spray with Luna Sen for treatment.
Through systematic shaping techniques and scientific care, rose bonsai can maintain its ornamental value throughout the year. The key is to grasp the timing of grafting, control pruning intensity, and maintain nutritional balance. It is recommended to establish a care log, record each pruning and fertilizing data, and gradually form an individualized shaping and care system.
