I love the raised beds and you probably will too. I have 20 raised beds of various sizes from 2x4 to 4x8 and I get all the wood (cedar) for free.
The fence companies around here put all of their scrap wood in front of the yard and in boxes for the taking.
We got the larger ones by taking apart these huge cedar pallets and using the wood to make frames and all of the smaller ones that are 2x4 or 4x4 that I would not normally build that small came already assembled.
I have no idea what they used them for but the wood is all cedar and looks brand new and they are screwed together into frames already.
I got 12 more of the small ones yesterday, already assembled and ready to go and I used those for the potatoes.
Those are good for planting potatoes in, you can just keep throwing another frame on top of another as the plants grow and you keep adding the dirt.
Then when you want to harvest you just pull the frames off and the potatoes are right there in the mound of dirt, no digging.
I planted 12 kinds of potatoes this year.
You can grow alot in those beds, I have done lettuce, corn, various squashes, tomatoes, strawberries, peppers, garlic, kohlrabi,beets, radish, carrots, beans, broccoli, cauliflower etc.
There isn't much you cannot grow in a raised bed. I even planted watermelon in one last year but they climbed out and grew along the ground, it looked cool though ;)
You can put a stick or bamboo teepee in the middle and plant runner beans or climbing peas up them and then plant lettuce, spinach or swiss chard around the bottom.
It looks awesome.
I do the companion planting-the three sisters and I also do the square foot gardening methods.
They all work and they are all fun to experiment with and just play around with.
The soil warms up faster in the spring and drains better in raised beds.
I wish you lots of fun and success, you will keep adding more and more beds you know, it never stops....
Man, I love the fence company!
