Does the Nasturtium Climbing Plant Climb?
Among balcony planting enthusiasts, nasturtiums are highly favored for their bright flowers and unique leaf shapes. The semi-vining nature of this plant often raises questions: Does it possess true climbing abilities? This article will delve into the growth habits of nasturtiums and impart practical climbing cultivation techniques.
Analysis of Nasturtium Climbing Characteristics
The Growth Mystery of Semi-Vining Plants
Nasturtiums belong to the category of perennial semi-vining plants, with stems that have缠绕 characteristics but lack autonomous climbing abilities. When the branches exceed 40 centimeters in length, they naturally droop to form a hanging landscape. To achieve vertical climbing, artificial intervention and guidance are necessary.
Differences Between Natural Growth and Artificial Assistance
Experimental data show that unsupported nasturtium branches can grow up to 2-3 meters per year but present an unordered drooping state; while plants guided by supports can form a 2-meter-high立体 flower wall, with a 40% increase in flower production.
Three Core Techniques for Nasturtium Climbing
Stereoscopic Support Construction Plan
It is recommended to use plastic-coated iron wire with a diameter of 3-5mm to make arch-shaped supports, with horizontal supports set at 15cm intervals. For window sill planting, a telescopic grid frame (with a mesh size of 10×10cm) can be used, ensuring ventilation and ease of shaping.
Scientific Tying Techniques
Use the figure-eight tying method: Form a buffer ring with green gardening ties between the branches and the support every 20cm. Leave 1cm of growth space to avoid damaging the stem.
Precise Timing for Pinching
When the main stem reaches 30cm, the first pinching is done to promote the growth of 3-4 lateral branches. Stop pinching when the lateral branches reach 50cm, and applying phosphorus-potassium fertilizer (N-P-K=5-10-10) at this time can enhance the flexibility of the branches and improve climbing ability.
Advanced Maintenance Points
With 6 hours of sunlight daily and a temperature of 20-25°C, the growth rate of the branches can reach 10cm per week. Supplementing with seaweed fertilizer monthly can enhance the plant's resistance and make the leaves thicker, which is beneficial for photosynthesis.
Through systematic guidance, nasturtiums can form a 1.5-meter-high立体 flower wall within 3 months. Mastering these techniques will allow you to create a stunning vertical garden landscape.
