Gardening is great for seniors, but not when you have to bend over for a long time, in the flower- vegetable garden. It's strean for the bloodvessels in the head and seniors become dizzy. So, why don't we bring up the flowerbed or veggybed to table level? In this video I show an easy way to make a tablegarden from 1 board plywood, complete with the saw-drawing. Most ideal for small town gardens and balcony. Total costs; about 50 dollar/euro. Some tips: Some plywood has a good and a bad side; keep the good side outside. Put the bottom of the container a bit higher, so you get a drip flange. You can change the height by connecting the legs higher or lower to the container. You can put easily wheels under the tablegarden. This is a open source hardware project.
