I've been a little bitten by the cacti and succulents bug. I was given an unidentified opuntia as a gift. It needs repotting as it is in a paper cup! I'm so charmed by this plant that I've ordered online a variegated opuntia, an aeonium (sunburst), and an agave victoria-regina . Talk about not being able to stop buying plants! I have a south window with plenty of space. I need a potting soil mix recipe. I have on hand, shredded bark, perlite, peat, vermiculite and two sizes of dynarock (medium and small). I dont have any sharp sand, nor am I really sure what sharp sand is, exactly. I also have some standard "store bought" potting mix. Any advice out there?
I've been growing amaryllis and worseleya for about 10 years, just as a hobby. While I love them, I need a new challenge. And those darned opuntias are so cute!
