One of the lessons learned this year was that mulch can bring extra issues to the garden. Our biggest pest explosion was pill bugs, followed by slugs, and a few ear wigs. Many of our peppers, among other crops, were damaged by them.
I have only done one bed so far. It is a lot of extra work to add the hardware cloth, which in my case is a 1/2 inch wire mesh, to the beds after they are finished. Anyway, we have enough mesh for 6 of our 10 beds. From the pictures below you can see snow accumulation. It won't stick yet but it is showing up early this year. (10-24-2013)
