Sherry, that's exactly my plan! The next place will be our last place, so I'll make it as lower maintenance... This yard was my big project, but I didn't factor aging into it, when I started it 5 years ago - guess I didn't believe it would happen, but gardening on hills is for the young(er)...
The blueberries are currently in ugly plastic pots, but want to put them in something more decorative. The half barrels are currently empty.
We bought one of these pot-lifters at the Garden show a couple of years ago - it would help you lift those 15 gallon trees with Jerry's or your son's help:

Garden shows coming up soon - yay for my DH who produces their commercials & got us free tickets again!
