How to Care for Newly Bought Climbing Roses
The key to whether newly acquired climbing roses can survive and bloom into a spectacular flower wall lies in the details of care during the first three months. As a star plant for courtyard landscaping, its growth characteristics require both scientific management and attention to the rhythm of care. This article will systematically analyze the key points of care from five dimensions.
Basic Care System for Climbing Roses
1. Soil Mixture and Potting Techniques
Quality substrate is the foundation for the flowering of climbing roses, recommended to use a golden ratio of "peat soil + decomposed leaf soil + perlite" (5:3:2). Retaining 1/3 of the original soil ball during repotting can reduce stress reactions. The new pot diameter should be 10-15cm larger than the original pot, with a 3cm thick layer of ceramsite at the bottom to enhance drainage. After planting, gently press the soil to allow the roots to fully contact the substrate.
2. Environmental Adaptation and Light Management
During the acclimatization period, maintain the optimal temperature of 18-25°C, with air humidity controlled between 60%-70%. Ensure 6 hours of direct sunlight daily during spring and autumn. From 11:00 to 15:00 in summer, use a shading net to filter 30% of the light. In winter, if temperatures drop below -5°C, take anti-freezing measures such as earthing the roots and wrapping the branches. Use decay-resistant wood for the trellis, maintaining a 15cm distance from the plant.
3. Golden Rule of Water Control
Adopt the "dry-wet" watering method: 3-4 times/week in spring and autumn, twice a day in summer (morning and evening), and once every 7-10 days in winter. Use the bamboo stake insertion method to test moisture: if the soil is dry at 2cm below the surface, it needs water. Continue watering until water seeps from the bottom of the pot. During the rainy season, promptly empty accumulated water in the saucer to prevent root rot.
4. Scientific Fertilizing Timeline
Start the fertilizing cycle 15 days after planting: apply high-nitrogen fertilizer (N-P-K=20-10-10) during the germination stage, switch to high-phosphorus-potassium fertilizer (10-30-20) during the budding stage, and apply balanced fertilizer (15-15-15) after flowering. When using organic fertilizer as a base fertilizer, keep it 5cm away from the roots, and apply solid fertilizer in a circular trench around the pot edge. Liquid fertilizer should be diluted at a ratio of 1:1000 and poured at the root.
5. Core Principles of Shaping and Pruning
In spring, cut back to retain 3-5 main branches, leaving 3-4 buds on each branch; after flowering, promptly remove the残花 up to 1cm above the five small leaves; in autumn, lightly prune to remove weak branches. Pruning tools must be disinfected with 75% alcohol, cut斜口 at a 45° angle to avoid water accumulation, and apply wound healing ointment to large wounds to prevent bacterial invasion.
Through systematic care including soil improvement, environmental control, precise water and fertilizer application, and scientific pruning, newly purchased climbing roses can form 1.5-2 meter flower branches in the same year. It is recommended to conduct monthly pest and disease prevention, regularly rotate the pot to ensure even exposure to light, and spray with trace element foliar fertilizer. As early as the following year, you can harvest a stunning effect of a three-dimensional flower waterfall.
