I guess your deer are much smarter than ours. I got 3 lots with 60” from Lowe,s , I don’t have a problem with them. Sometimes I leave the gate open, forgot to close. I wouldn’t write if it didn’t work. It doesn’t have to be figs, I also grow Kerea bushes right against the fence. This bushes grow fast up to 6 feet tall, nice yellow flowers right about now.
The reason I pick figs, got to eat the fruits while being protected. If you have a lot of figtrees and you don’t know what to do with them.
