Starting a new raised bed is easy with some cardboard over the grass and then pile soil on top. We got the soil free off Craiglist!
The boards were free too, laying around the yard when we moved here. We pounded short 2x4 stakes in the ground at the corners and then screwed the boards to them.
I back filled the box with the soil and then planted it with the tomato and cuke starts from the greenhouse. On the ends I planted a couple of squash plants, figuring that those and the cukes can cascade over the sides of the box as they grow.
These little boxes were another free Craiglist find from last year, filled with our free soil and then the bamboo stakes were found on the side of the road and make great places for the peas to climb!
This little bed is going well with peas and some yellow bush beans on the outside of the circle. They're climbing on some bamboo poles we got off...you guessed it, Craigslist and the rocks came from our neighbour accross the street who gave us several wheelbarrow loads of black, gooey soil dug from his ditch. I considered it black gold and my good husband brought it all back, rocks and all, for our gardening use.
All of our neighbours are great, though I must admit I do like a little privacy in the garden. We planted the hedge last year and now as it grows I am making more trellis contraptions from bamboo. This pot will have giant scarlet runner beans and in the background is a trellis I made for the hops to climb on.
These tomatoes are quite happy with the south western exposure and the lettuce goes along for the ride. Free bricks from Craigslist surrounding... Behind is the patio screen we built in the fall and next will be a planter on the ground in front of it, filled with climbing cucumbers and some nasturtiums I think. Gardening is cheap entertainment for me and we get food as a bonus. Hope you get a little inspiration from seeing what can be done with a little dirt and some imagination. Have fun!
