Thanks for your question. Before I can answer it, I need clarification on a few points.

1). I would be very surprised if squirrels are eating your plants. Green plants are not an expected component of their diets. However, they do like to dig them up. Could you please clarify why you think that squirrels are actually eating your plants?

2). Rabbits certainly do munch on plants. Is it possible that rabbits are solely responsible for all the actual eating of your plants?

3). When you tried fencing, what was the fencing material and how high was the fence?

4). Is it possible that some of the plant damage may be attributable to deer?

I ask these questions because dealing with squirrels is very different from dealing with rabbits. Two different strategies are employed. This is why I need to determine who is the major culprit: squirrels or rabbits.

Many thanks for your time in responding to these requests. Thanks for consulting us.
