Years ago, I moved to a very rural location. I became very frustrated with squirrels eating pretty much my entire crop of tomatoes. I decided to relocate my hobby to escape the rodent thieves. I have a perfect exposure behind my store in the city, sun from sunrise till about 3 pm. A tree farming buddy gave me some 15 gal containers and so far so good. Been growing in this location about 5 years now. Nobody bothers them and, since I added the drip irrigation, production is excellent. And NO SQUIRRELS!!
