Placing urban planter boxes directly on the grass in a shared courtyard is a common question for community gardeners. While it might seem convenient, there are important factors to consider for the health of your plants and the shared space.
Firstly, placing a planter box directly on grass can block sunlight, air, and water from reaching the grass beneath, eventually killing it and potentially creating a muddy patch. This can lead to an uneven and messy appearance in the communal area. Furthermore, the damp, dark environment created can attract pests like slugs and promote mold or fungal growth, which might affect your plants.
For the plants inside the box, drainage becomes a critical issue. Most planter boxes need adequate drainage holes. When placed on grass, these holes can become blocked by soil or sod, leading to waterlogged roots and root rot. The grass itself can also grow into the drainage holes, creating a nuisance.
A better solution is to use pot feet, bricks, or a small gravel base to elevate the planter box slightly off the ground. This ensures proper drainage, allows air circulation underneath, and helps preserve the grass below. It also makes it easier to check for pests. Always consult with your neighbors or building management before making changes to a shared courtyard. By taking these simple steps, you can create a thriving garden that respects the shared environment and keeps your plants healthy.
