Pick your own Oak Trees (Blofield NR13)

Over the last couple of weeks I've had loads of self seeded oak saplings spring up. Most are only a couple of inches tall at the moment, but I'm hoping someone can give at least a few a good home. I'm very reluctant to just mow over something that could potentially outlive us all by several hundred years, but I really don't want a forest in my back garden. Help wanted please.
