Raised beds are fantastic for small-space gardening. They allow clear walkways so you aren't always stomping through the middle of your cucumber patch and they make it easy to harvest veggies and cut flowers because the bed is 12 to 18 inches higher than the pathways. If you are building your own raised beds, though, it's important to reinforce the corners so that the sides don't bow out. You can reinforce the corners with extra lumber, or with metal L-brackets.

Figure out what size raised bed will work best in your garden. Larger raised beds, those that are more than 4-square feet, will need stronger support at the corners than smaller beds, which will be fine with inexpensive L-brackets from the hardware store.
Overlap the short wall of your small raised bed over the ends of your longer walls. Drill guide holes through the overlapping wall directly into the ends of the longer walls, and screw the walls together.
Reinforce the corners by attaching 2-inch L-brackets in the inside top and bottom of each corner, making sure to stagger the brackets in between the main screws.
Small Raised Bed
Cut 4 lengths of 4-by-4 lumber, with each piece at least 4 inches longer than the height of your raised bed.
Drill guide holes and screw the long walls of your bed to the posts. Leave the extra 4 inches of post exposed on top of the bed until you have it built and can dig it in and flip it over.
Level the bottom edge of the sides and screw the short walls of your bed to the posts instead of into the other walls.

Tips and warnings
- Each board that is attached to a bracket or post should have at least two screws to anchor it, so that nothing pivots around a single screw.
