Can I Add a Roof or Trellis to a Planter Box Built with Cinder Blocks?
If you’ve built a planter box using cinder blocks, you may be wondering if you can add a roof or trellis to make it more functional or visually appealing. The good news is that it’s definitely possible, but you’ll need to consider a few factors before getting started.
Roof
Before adding a roof to your planter box, make sure it’s sturdy enough to hold the weight. Cinder blocks are dense and heavy, so you’ll need to use a structural material that can support the added weight. You can use wood or metal frames to create a roof, or even repurpose an old wooden pallet or a metal grate.
Here are some tips to keep in mind:
- Choose a material that’s durable and weather-resistant
- Ensure the roof is slightly angled to allow water to run off
- Consider using a waterproofing membrane to prevent moisture from seeping into the planter box
Trellis
Adding a trellis to your planter box can provide support for climbing plants and add visual interest. You can use wooden stakes or metal rods to create a trellis, or even repurpose an old wooden ladder or trellis.
- Choose a material that’s sturdy and durable
- Ensure the trellis is securely attached to the planter box to prevent it from toppling over
- Consider using plant clips or stakes to hold the plants in place
Tips and Considerations
- Check local building codes and regulations to ensure your addition complies
- Consider the drainage and watering needs of your plants
- Make sure the weight of the roof or trellis doesn’t compromise the structural integrity of the planter box
- Don’t forget to seal any gaps or cracks to prevent pests and weeds from entering the planter box
How Do I Prepare Cinder Blocks for Use in a Planter Box Project?
Before building your planter box, you’ll need to prepare the cinder blocks. Here’s a step-by-step guide to get you started:
Gather Equipment
- Wire brush
- Power washer or hose with spray nozzle
- Sand or a sanding block
- Concrete patching compound (optional)
- Clean water
- Dropper or small brush
- Caulk (for sealing gaps)
Clean the Cinder Blocks
- Use a wire brush to remove any loose dirt, debris, or old mortar from the surface of the cinder blocks.
- If there’s stubborn dirt, use a power washer or hose with a spray nozzle to blast it away. Be cautious not to damage the blocks.
- Rinse the blocks with clean water to remove any remaining dirt or debris.
Smooth the Surface
- Use a sanding block or sandpaper to smooth out any rough edges or surfaces on the cinder blocks.
- Wipe away any dust or debris with a damp cloth.
Seal Gaps and Cracks
- Inspect the cinder blocks for any gaps or cracks. If you find any, use a caulk gun to fill them with a waterproof sealant.
- Smooth out any excess caulk with a damp cloth or dropper.
Apply Concrete Patching Compound (Optional)
If your cinder blocks have large cracks or are damaged, you may need to use concrete patching compound to repair them. Follow the manufacturer’s instructions for application and drying times.
Allow to Dry
Let the cinder blocks dry completely before assembling your planter box. This may take several hours or overnight, depending on the weather and the type of preparation you’re doing.

How Do I Ensure Drainage in a Planter Box Made with Cinder Blocks?
Creating a planter box using cinder blocks is a fantastic way to add some greenery to your outdoor space. However, when using cinder blocks, it’s essential to ensure proper drainage to prevent waterlogged soil and root rot. Here’s a step-by-step guide to help you achieve optimal drainage:
Step 1: Add a layer of gravel Begin by filling the bottom of the planter box with a 1-2 inch layer of gravel. This will allow excess water to drain freely.
Step 2: Use a permeable top layer Choose a soil mix with good drainage properties, such as a mix that contains perlite or vermiculite. Avoid using regular potting soil, as it can retain too much water.
Step 3: Install a drainage system Drill 1/4 inch holes in the bottom and sides of the planter box. This will ensure that water can escape and prevent waterlogging.
Step 4: Monitor and adjust Regularly check the planter box for signs of waterlogging, such as soggy soil or running water. If necessary, adjust the drainage system by adding more gravel or holes.
By following these simple steps, you’ll be able to create a planter box that’s both functional and aesthetically pleasing. With proper drainage, you can enjoy healthy, thriving plants and a beautiful outdoor space.
