Ok so I have numerous amounts of dehydrated rose petals and hibiscus petals that I use for my hermit crabs that are all natural and pesticide free. Well the problem is, is I'm getting so much extra from my happily flowering plants (it's spring and all) and being me I don't like to waste any so I've still been dehydrating them. I was wondering if both plants would be a safe bet to feed to the roaches? The rose is a miniature rose, don't know if that matters but I'll put it out there.
