I am getting ready to try a new experiment with gardening. Because the soil in my backyard is quite rocky, I am going to try some raised beds. What I intend to do is get some of the plastic fruit bins that are used by the farmers all over the Sacramento Valley and convert them into raised bed gardens.
The bins are made of heavy plastic and are approximately 4 ft square and between 2 to 3 foot high. They are available with solid sides and small drain holes in the bottom. Once set in place they would last for many years, no termites or dry rot. Because they are palletized on the bottom, they would have a gap of approximately 6 inches between the ground and the bottom of the box.
They would be easy to maintain, require no bending or getting down on your knees to weed them. No gophers or moles could get into them. Buying older ones from the farmers there are cheaper than building redwood boxes and a lot less work.
When they are filled with dirt they will be quite heavy and if correctly placed could be used to deny vehicle entry to an area.
It will be interesting to get several of these and then practice square foot gardening in them. I should be able to raise a lot of food in a small area. I will write more as the project progresses.
