I am gardener at the SMLC and have used only raised mounds and I found last year that the weeds and grasses grew up on the edges of my mounds. I used hand shears to cut down the weeds periodically and found that the weeds root structure made a nice firm barrier upon which I could add more compost and soil. Although this technique takes more time it is very inexpensive. Also I was not sure how much the weeds were actually affecting the soil of the raised bed. I did however have healthy plants growing along side those pesky weeds.
On a related note I have done some research into building raised beds for potential clients/gardeners who do not have space or time to build up a full size garden. Since I am a builder by trade I estimated that the cost to build a 4’ by 10’ raised box with composted soil would cost around $70 in materials. The materials would consist of 2 x 6 western red cedar without a weed barrier and about 1 cubic yard of composted soil. I agree with Mr. Dyer in that once the box is made you shouldn’t have to do much more than continue to amend the soil with compost and rotate your crops to encourage a balanced soil.

Dick,
thank you for the contribution of valuable knowledge in this matter!
P.S. Garden Orientation this coming Saturday, May 16 -- details to follow.
A few words about compost…
Think of Bin #1 as the pantry…a place to store your kitchen scraps, weeds, leaves, grass clippings, etc…
Think of Bin #2 as lasagna baking in an oven…
Think of Bin #3 as dinner on your plate!

Bin #2 has been cleared out this weekend. We laid cornstalks and large stems on the very bottom to facilitate air flow from the bottom up—then a layer from Bin #1 is added, then a layer of manure, then a layer from Bin #1, then manure, etc. continuing in this manner until Bin #2 is full.
A note about Bin #1…There are pockets of dry leaves, manure, kitchen scraps, green weeds. Rather than taking off this pile horizontally to add to Bin #2, go vertical. For example, I started digging in the right side of Bin #1 started at the front—working towards the back. This way the pile doesn’t just get flipped, it gets mixed. When you hit a pocket of greens or browns, spread it evenly across Bin #2, so there aren’t specific pockets. Then throw a layer of manure on top.
It would be great if Bin #2 could be layered and filled this week so it doesn’t dry out. Try to keep the pile level rather than heap it up in the middle as piles tend to be created. If everyone spends a few minutes on this task, it should get done soon and then in 2 weeks or so, we should have some good compost to add to our plots and our newly planted veggies!
As always—if you have questions, please ask!
This past weekend, I started turning the middle bin into the third bin. If you are out at the garden this week, take a few minutes to move some of bin #2 into bin #3. As soon as bin #2 is cleared out, we’ll start turning bin #1.
Also, I will take donations for Plant a Row for the Hungry campaign to Food Gatherers in the next few weeks. If you have plenty o’ produce and would like to donate to our local food bank, let me know please.
