There are many ways to build a raised bed Square Foot Garden outside your tiny house. I built my first raised bed Square Foot Garden from 2×6 pine boards measuring 4 feet wide and 8 feet long, held together with galvanized screws. My raised beds served me well for many years, with very little weathering.
Cedar boards are naturally decay resistant, but will certainly increase the cost of your project. Less expensive raised bed Square Foot Gardens can be made from cement blocks, used bricks, rocks, pine logs, or woven willow.
Avoid the use of wood such as railroad ties, pressure treated wood, and used pallets, as as toxins may leach into the soil, be taken into the plant through its roots, and may be consumed by you and your loved ones.
Experience and an aging body have taught me that when I build raised beds for my tiny house Square Foot Garden, they will measure 3 feet wide, instead of 4 feet wide, and at least 12 inches in height, so that I do not have to stretch as far, kneel, or stoop so low to the ground.
Furthermore, a preemptive layer of vole-proof mesh stapled to the bottom of each raised bed before filling with soil would prevent winter peas from being chewed to stubs. Although not good climbers, voles are expert tunnelers, and they have voracious appetites.
The M Brace offers an additional method of creating a raised bed Square Foot Garden that is as portable as your tiny house. Designed for a level surface, the M Brace makes it possible for even a child to assemble a raised bed Square Foot Garden in a few minutes, using pre-cut lumber. Should the need ever arise to disassemble your raised beds and take them with you, they can be torn apart as easily as they are assembled. The soil could be transported in a tarp, or thinly spread at the current site and replaced at reassembly.
Made in the USA from 100% recycled steel, with many designs to choose from, the M Brace will rust to a lovely patina, creating beautiful and playful art for your garden.
