Great idea! Until they get big enough to not worry about damn chipmunks and others digging. I also have luck spraying deer/rabbit repellent around area. Chipmunks and alike were around yard but stayed away from plants. I would get this stuff @DMChiz a little stinky for a day but goes away.Yeah they are pretty exposed with just tomato cages. However the cages gives you something to anchor to if you want to wrap chicken wire around it for critter deterrent.
