This raised bed uses concrete blocks covered in surface bonding cement and then painted with black patio paint. This inexpensively creates a high-end look without a high-end cost.

We like this option because the blocks will never have to be replaced due to rot; they will likely last decades. The paint can be done in any color that matches the patio decor, which is a nice bonus. Plus, having a flat-edged border provides a great place to sit and drink a cup of tea or plant vegetable seedlings.

A vertical garden is an excellent design idea. This one is so well done it looks like a work of art. The real beauty of DIY projects like this is their versatility and ease. The blocks are simply stacked in any eye-pleasing pattern and held there by their own weight, no mortar needed.

This is a great DIY project to complete with the kids. Many different designs can be created with some bright acrylic paint and a little imagination. These blocks were striped with painter’s tape and then painted, but they could be drawn with pictures, animals, or flowers to spruce up the patio.

4. Use Stencils to Make Beautiful Cement Planters

This idea looks like so much fun. The cement blocks are first painted white. Afterward, a bright color is applied with a stencil and a flat stencil brush. We like the idea of using a different pattern and color on each side of the block. Grouped together, these make a picture-perfect border or focal point for the patio.

5. Encrust Cinder Blocks with Tile Mosaic

This DIY project takes a little bit more patience and skill, but it will be well worth it. Look at the beautiful work of art it creates! This look is created by nestling two rectangular cinder blocks side by side to form a square, then carefully adhering mosaic tiles in a unique pattern.

6. Create Garden Edging

The idea of creating a garden wall or edge with cinder blocks is not new, but this colorful take on the old theme is fresh and beautiful. We especially love the idea of placing the blocks hole-side up and using them as small flower pots. A long edge of bright flowers creates a tidy border without the weeds.
