First up is growing vertically. Using things like stakes, trellises, and fencing can help you maximize your space by using the vertical space instead of the horizontal space.
If you have a traditional row garden, try planting double rows instead of single. Plant 2 rows of the same crop close together with a larger space between each double rows.
