Are rose bush roots safe for a viv?

Depends on if the roses were heavily fertized. I have used rose roots in a bunch of viv's. They are very eye appealing and they do not break down. I have had some in viv's for several years before they started to deteriorate.

Sweet. Thanks. The bushes weren't fertilized, but the yard around them was once a year. I plan on washing them, sitting them in the sun for a week, and then storing them away until I can use them. I'll boil them before placing them in the tanks, but it's probably going to be a good six months before I get around to building my next vivs.
