I'm thinking about fruit trees and bushes specifically. If you've ever gone apple picking you see how many apples are on the ground. Domesticated fruit trees are bred and grafted to be highly prolific, and you'll have a lot more fruit dropped than you'd think.

Plus you'll have animals going into the trees to eat the fruit. Commercial berry farmers have to cover their bushes and trees with nets to prevent birds from picking them clean. (And then producing very colorful art on outdoor surfaces.)

I'm not saying it's a bad idea, but I don't think people have entirely thought it through.
