in my experience the pavers heave a lot more than cinder blocks.
Cinder blocks, buried 3 inches at the bottom, are the best choice in
cold areas. In all cases (blocks or pavers) the soil around them will
be limed for at least one foot.

Hm, I did not know that when I built my flower bed. I have not seen
sign about the PH changes yet. Do I need to add something acidic? Soil
here (Urbana, IL) is acidic to start with I believe.
