I am wondering if it is OK to bury the canes in manure. For the most part, I try to keep the manure away from the canes, instead mounding it around the plant.

I deviated from this on a few plants, and buried the canes in up to 6 inches of manure. Apparently, the rose didn't mind this treatment at all, and has grown like crazy.

With this in mind, is it a good idea to bury all of my roses like this?

My only concern against this approach would be rotting-out the canes that were buried. For instance, they say never never bury the base of a tree in mulch, because the trunk will rot. Is this a problem with roses as well?

If you want to FERTILIZE your roses with manure, it's not necessary to bury them then either. What's the point? The plant is beautiful in it's own right, and it needs air circulation for healthy growth and disease resistance. And yes, it could just rot by having wet manure next to the main trunk.

There's a reason it grows OUT of the soil. That's where it needs to be.
