We built these before we saw these plans, but they are pretty much the same... We added the chicken wire to keep the rabbits (and our dog) out of the garden. We added the owl to keep the birds out.
We've gotten a ton of tomatoes, onions, and bell peppers so far. Next year, we'll add a few more beds.
We also added the verticle garden to take up less space, but its not deep enough. We'll make the next one deeper.
