How to build a cinderblock raised garden bed step-by-step 🌱
1. Mark out your size
(This one is 8ft x 14ft x 16in tall)
2. Dig out your footer/trench
3. Install 3–4 inches of gravel/rock and compact it well
(We use a 2x4 and a 4ft level to make sure everything stays the same height.)
This step is key because any uneven spots will create gaps and will be very noticeable.
4. Lay your first course of block level side-to-side and front-to-back
5. Dry lay the second layer, interlocking the corners first, before gluing anything down. This helps make sure everything looks good and stays secure.
Take your time on the base — the final result is only as good as the foundation 👌
