Growing ivy on a wall can add a beautiful, natural aesthetic to your property, but it requires careful planning and maintenance to ensure both the plant's health and the integrity of your wall. The key lies in strategic planting and selecting the right species.
Key Considerations for Growing Ivy on Walls
To successfully cultivate ivy on a wall while minimizing potential risks, follow these essential guidelines. These practices ensure healthy growth and protect your building structure.
1. Proper Planting Distance from Walls
When planting ivy, it's crucial to give it enough space to establish itself without immediately impacting the wall's foundation or drainage.
- Plant at least 30 cm away from the walls. This distance helps prevent the ivy's roots from directly interfering with the wall's foundations or causing moisture issues right at the base. It also allows the plant to develop a healthy root system before its tendrils begin to climb.
2. Ensuring Adequate Space Between Plants
If you're planting multiple ivy plants to cover a larger area, spacing them correctly is vital for their development.
- Leave sufficient space between individual ivy plants. Proper spacing promotes good air circulation, reduces competition for nutrients, and allows each plant to establish a strong base before intertwining and covering the wall. This also prevents overcrowding, which can lead to disease.
3. Understanding Watering Requirements
Ivy, especially once established, is remarkably resilient and often requires minimal watering.
- Most ivy species need watering only during their first growing season. After this initial period of establishment, mature ivy plants are typically quite drought-tolerant and can thrive on natural rainfall, making them a low-maintenance choice for ground cover or wall climbing.
4. Choosing the Right Ivy Species
One of the most critical decisions is selecting an appropriate ivy species, as some can be highly invasive and potentially damaging to structures.
- Avoid using invasive species such as the English ivy (Hedera helix) on your house. While popular, English ivy is known for its aggressive growth and strong aerial roots that can penetrate and expand cracks in walls, potentially causing structural damage over time. This is especially true on buildings with existing cracks in the walls. Opting for less aggressive or non-invasive climbing plants can prevent future issues.
