the issue .. simply put is liquid water ... on a frozen media ... you know.. those days where its warm enough for snow thaw ... or rain.. rather than snow ...

the media.. which is chosen for drainage.. all of a sudden.. being frozen soil.. does not drain ...

a secondary issue is the freeze/thaw cycles in very late winter ...

once the media is frozen.. just dont let water accumulate ... heck i have extra garbage can lids .. kids saucers .. cardboard anything.. to just shield ... rose cones ... or deflect liquid water ... JUST DONT LET HEAT ACCUMULATE UNDER ANYTHING ...

when its still winter.. but basically spring.. early march.. z5 ... take the stuff off.. no waiting until may ... lol .. let nature bring them out of dormancy..

do NOT let any heat accumulate .. so i would prefer full shade ... house.. bench.. deck ... etc ...
