What size pot for planting ivy
In vertical greening plants, ivy is favored for its powerful climbing ability and vigorous vitality. For beginners who are new to this plant, there are often many questions about pot selection and fertilization management. This article systematically sorts out the key points of care based on practical planting experience.
Pot selection and substrate preparation
Container volume standard
It is recommended to use a 5-10 liter container as the basic setup, with pots over 30cm in diameter for seedlings. As the plant grows, a larger container should be replaced after 2-3 years, and adult plants are recommended to use large jars or custom planting boxes over 50cm in diameter.
Application of special containers
Polystyrene boxes are an economical choice and need to have drainage holes drilled in the bottom. Old-style ceramic pots have good breathability but are heavy, while plastic pots are light but need to be shaded to prevent aging. The amount of soil in the container should be controlled at 4/5 of the space, leaving a growth buffer zone.
Management plan for new seedling fertilization
Techniques for applying base fertilizer
Mix decomposed sheep manure (3kg/m³) or slow-release granular fertilizer (200g/m³) at planting, and stir it thoroughly with garden soil. Avoid direct contact between fertilizer and roots, maintaining a 5cm isolation layer to effectively prevent root burn.
Timing for top dressing
No top dressing is needed for the first 3 months after transplanting new seedlings. Enter the rapid growth period (from the 4th month) and apply diluted liquid fertilizer every 45 days, with a recommended NPK ratio of 3:1:2. Stop fertilizing after September to promote lignification of branches.
Systematic care points
Light and water control
Maintain 60% shade for seedlings, and mature plants need full sun. Use the immersion watering method in summer to keep the substrate moisture at 30%-40%. Control water in winter until the topsoil is dry before rehydrating.
Disease and pest control
Regularly check the back of leaves to prevent red spider mites, and treat them with sophoraflavescens solution at the initial stage. Spray Bordeaux mixture before the rainy season to prevent (T-J) disease, and maintain plant spacing to enhance ventilation.
Shaping and pruning techniques
Pinch the main vines when they reach 1 meter to promote side branches. Prune weak and dead branches heavily every early spring, retaining 5-7 main growth points. Use hemp绳 to secure the vines against the wall, avoiding the use of metal wire to prevent stem damage.
Through scientific selection of planting containers and precise fertilization management, combined with systematic care measures, ivy can form a complete vertical green landscape within 3 years. Regularly observing the plant's condition and timely adjusting the care strategy can ensure its continuous and healthy growth.
