Answer: Fall is a great time to plant. Set the blackberries in the sunniest spot in your garden. Don't prune them after planting; wait until spring to cut them back. Flowers and berries will develop on the new wood of the season so trim the canes back to about 24" above ground level in early spring. You'll see new growth emerge within a few weeks.
Rose of Sharon also enjoys full sunshine. Again, these flower on new shoots of the season so wait until spring to prune them back. If you don't prune at all, you'll get lots of small blossoms; if you prune them back each spring, you'll get fewer, larger blooms.
Best wishes with your garden!
