Depends on what you grow.

I had a half acre, and something like tomatoes means you have to can them because you can't eat them all once they are ready, and a pear tree that would produce wheel barrows full for weeks so I had to start brewing Perry.

But in the city with only a 10x10 plot it was pretty slow going except for cherry tomatoes...those grew like wildfire up and over the fence etc. So many we had to give them away.
