Chipmunks kept digging burrows in the middle of my raised lettuce bed, and were not discouraged by my feeble efforts to close their access holes. Finally I bought some 10 foot aluminum gutters, drilled drainage holes in the bottom and filled them with half compost, half potting mix. They get watered every other day. As you can see from the picture, lettuce, arugula and mizuna are doing quite well in them, even the romaine that had been flopping in the previous bed firmed up to nice heads, and so far there has been no sign of damage from chipmunks or squirrels.

When I get a chance, I may dig out the raised bed below and line it with wire mesh hardware cloth to see if that will permanently defeat the burrowers.

Good idea!
I have some gutter plastic,
and was going to grow lettuce in them
because I had heard some hydroponic growers use them.
Really don't need big pots for lettuce.

What a great idea Don.
We have all of our raised beds lined with 1/4" hardware cloth, and in 15 years have not had a problem with burrowing rodents.

That looks great!
