This is the year I allow no bunny access to my vegetable garden. The height and recycled metal is perfect to divert my city rabbits to my clover and sweet grass patches. Construction was easy with a little help from my 8 year old grandson. We utilized twigs, branches, wood to fill the bottom; complete compost for the middle; and a 1/3 blend of each peat moss, vermiculite, compost for the top layer. I anticipate these will last year's and I will amend the soil every year with a top off of good finished compost. My 16' hog panels between beds will allow for my vertical climbers to maximize output.
