Strawberries are an easy perennial you can grow in your backyard that can provide a yearly supply of fresh berries for jams, desserts and wines. The DIY strawberry pyramid built by Bonnie Plants in the video above is a great way for people with limited space to grow the productive plant.
They state that the total build costs $113 based off 2013 prices but if you use re-purposed building materials you could build one for a fraction of their estimated costs.
