Apple orchards up here are being abandoned, especially the old ones. There are still a lot of the newer type orchards being planted, with apple trees being planted only a few feet apart, with wires and such to support them.
The big change in my area is that a lot of the old orchards are coming out and being replaced with vineyards. Within 15 minutes of Wolfville there must now be 8 to 10 different wineries.
