Step-by-Step Instructions to Build Your Raised Garden Platform
Step 1: Planning and Measuring
- Choose a sunny location with at least 6 hours of sunlight daily.
- Measure and mark your desired platform size (commonly 4×8 feet).
- Decide on height (12-24 inches recommended for comfort).
Step 2: Cut Lumber
- Cut four side pieces using cedar or redwood 2×6 or 2×8 lumber.
- Cut additional support beams for the frame and optional legs.
Step 3: Assemble the Frame
- Using galvanized screws, join the side pieces to build the rectangular frame.
- Add cross supports every 2 feet for durability.
- Attach legs if raising the platform off the ground (recommended height 24 inches).
- Use a level to ensure the frame is even.
Step 4: Prepare the Base
- Lay weed barrier fabric inside the frame to prevent weeds.
- Drill drainage holes in the bottom or leave mesh for water flow.
Step 5: Fill with Soil
- Mix garden soil with compost (about 70% soil, 30% compost).
- Fill the platform evenly, leaving 1-2 inches from the top.
Step 6: Seal the Wood
- Apply a non-toxic, garden-safe sealant to all wood surfaces.
- This extends the lifespan by protecting against moisture and rot.
Step 7: Plant and Maintain
- Start planting your favorite vegetables, herbs, or flowers.
- Water regularly and add mulch to retain moisture.
