i'd have to ask what you meant by shrimp compost? if it is just the shells/heads from your eating shrimp, if you can bury it deep enough to keep critters out, then yes, we used to do that at home when i was a kid, living on the bayou. not with roses
, but with fruit trees. but, if you are talking about a commercial product, i really don't know rose
specific, although most compost would be good for most plants.
