Deer don't bother my pumpkins, but they played havoc with my cabbage and peas. I bought this stuff called Invisible Fence. It comes in a 32 oz spray bottle for around 10 dollars. Smells like a cross between rotten eggs and rotting garbage. Smell goes away in a few days, but the deer/rabbits/other varmints will stay away long afterwards. Apply once per week for the first 2-3 weeks then every other week after.
