Newbie with raised bed blues

Heya, I'm BastLoki (please call me Mal!) and I've been gardening on and off for the past decade - off due to my health, on because I adore fresh veggies and fruit too much to not want to make my own I like it best when it's organic, as well.

Anyway, my probelm is this: I'm thinking of raising one of my side beds to move my beloved food-plants out of their containers and into something a bit less scruffy-looking (I can't really afford those huge planters, so I tend to use rhino tubs with holes punched in the bottom ^^;, but my equally beloved rambling rose ( I think it's a rambler, anyway - Danse de Feur?) is smack-bang in the middle.

It's been growing there for nearly as long as I've been gardening, and it's two or three times my size, and fearsome with it's thorns, so I don't really want to move it unless I have to.

Basically, will dumping a foot or so of compost soil on it's lower stalks do a lot of damage, or will it survive being worked around?

Thanks for your time!
