When creating an urban garden, a common question arises: do planter boxes need to be elevated off the ground? The answer is a resounding yes for most situations. Elevating your planters is a simple yet critical step for ensuring the long-term health of your plants and the integrity of your surfaces.
The primary reason for elevation is drainage. Even planters with drainage holes can become waterlogged if they sit flush on a hard surface like concrete, wood decking, or stone patio. The holes can become blocked, trapping excess water at the bottom. This leads to root rot, a condition where roots suffocate and decay, ultimately killing the plant. Elevating the box allows water to freely escape, mimicking the natural, well-draining soil conditions plants thrive in.
Furthermore, lifting planters off the ground prevents staining and moisture damage to your patio, deck, or balcony. It also helps to deter pests like slugs and snails from easily accessing your plants.
So, how can you effectively elevate your planter boxes? Here are several practical methods:
1. Integrated Feet: Many modern planters, especially those made from resin, metal, or fiberglass, come with built-in feet. This is the most straightforward solution, providing a guaranteed and stable lift.
2. Pot Feet or Stands: You can purchase separate pot feet made of stone, ceramic, or plastic. Simply place one at each corner of the planter box. For heavier planters, a dedicated metal or wooden plant stand or caddy offers robust support and even allows for mobility.
3. DIY Solutions: For a custom or budget-friendly approach, use materials like bricks, concrete blocks, or wooden slats. A wooden pallet can also be an excellent base for multiple smaller planters, creating a unified raised garden bed effect.
Aim for an elevation of at least one to two inches to create sufficient air circulation and drainage space. By taking this simple step, you invest in the vitality of your urban garden, ensuring your plants have a healthy foundation for growth.
