Plant holders provide a healthy and decorative place to grow flowers and produce, but they can be costly if you buy them from a gardening supply store. One solution is to make wooden planters yourself using basic building materials such as plywood and a drill. Once they are finished, you can fill your handmade wooden plant holders with potting soil, then plant your favourite vegetables, fruits or flowers. You also may set your wooden planters on a sunny porch or balcony for display.
Drill a 1-inch hole into the centre of one 18-inch square sheet of plywood using a 1-inch spade drill bit. This is the drain hole for one plant holder.
Place the drilled plywood sheet on a flat surface.
Nail one 2-inch wide, 18-inch long wood stake vertically, or upright, into each corner of the drilled plywood sheet. This creates the skeleton of the planter holder.
Place a second square sheet of plywood against one side of the planter skeleton, and nail it into place against the upright stakes. Repeat this process until you attached an 18-inch square sheet of plywood to each side of the plant holder.
Fill the plant holder with soil, then put plants in the box.
