Last summer we had a good crop of tomatoes and went on vacation. When we returned the squirrels had eaten most of the tomatoes. They continued to eat them and we probably got two out of the garden that summer.
Update:This was the first year with the green house and I enjoyed starting my tomato plants from seeds. Early in the spring we started planning on how to keep the squirrels from eating them.
We quit feeding the birds because when we did there could be 14 squirrels in the yard at one time.
Build a prison for the tomatoes.
We built frames and covered them with hardware cloth.
Time: ~8 hours of work
Cost: Don't ask
We assembled the "cage" because they were already decimating the crop. The top was not completed yet so we wired some hardware cloth to the top for a temporary fix.
We tried to close up the place where he was getting in and reattached the top.
Finally we plugged up the place where he was able to get into the tomato prison. And he was so frustrated that he tried to eat the tomato through the wire.
Luckily we have a watch cat to keep away the squirrels.
He was on break.
