Very nice! I wish you all the luck, and I hope you learn a lot before moving on to your own place.
Those look like some hard working pigs: make sure to reserve a place for them at the dinner table. A trick I've used is to use a cord-less drill with an auger, and drill some 1" holes around the
roots (6-12 inches deep), and drop in acorns, peanuts (or whatever is handy). Those bushes will be history in no time!
