Oh blimey! He's off on one..................

Possible ideas for pt2 :

Composting (dead leaves gotta go somewhere)
A Managed water butt (would require weather changes though)
Soil testing (perhaps a kit, nitrogen, phosphrogen, pottasium)
Full sun and partial shade shelves (not all plants like full sun)

Im sure theres a lot more, but you can only put so much into a game huh?
