What can I do to keep them out? We have a government-issued garden plot surrounded by other garden plots in the middle of a flat field. No real practical way to put up a fence, no trees to hang anything from. I've read about different things but I'm having a hard time deciding what is real and what is myth.
Also, will they come back? I've read here about people cutting the tops off of indeterminate tomato plants to stop their growth so would getting the top bitten off my plant keep it from growing? They are still pretty little... only about a foot tall before the deer and about 8 in now

This is my first garden and I'm really excited but I would like to actually reap some of the rewards, yk?
