🛠️ Step-by-Step Guide
1. Plan Your Location
Choose a flat, sunny spot (at least 6 hours of sun per day). Raised beds work great in backyards, patios, or even urban balconies.
2. Build the Frame
Cut your wooden posts to the height you want (e.g. 24 inches).
Form a rectangular frame by attaching the corrugated metal sheets between the wood posts using galvanized screws.
💡 Use a power drill and metal screws to ensure tight and secure connections.
3. Secure and Level
Place the frame on the ground.
Use a level to ensure stability.Optional: lay landscape fabric under the bed to prevent weed growth.
4. Fill with Soil
Fill the raised bed with a rich soil mix — 60% topsoil, 30% compost, 10% sand or perlite for drainage.
5. Start Planting!
Now that your raised bed is ready, plant your favorite veggies, herbs, or flowers. Water deeply and mulch to retain moisture.
