Making a vertical garden

You can make a vertical garden out if pallets or a burlap sack.

Either will do fine, but the process is different.

Look for a pallet that was not treated with chemicals. Look for a pallet that has an "HT" printed on it somewhere. The "HT" means it was hear treated so it's safe to use for growing food.

Next, staple burlap or a geotextile to the bottom of the pallet.

Once all the corners are stapled,  lay it flat and fill it with soil.
