Hi Franz - I am trying to get information about the Rugosa rose, America. Could you please send me an email? anitac5159@gmail.com. Thanks.

Do you have experience making your own potting soil for roses? I can't use commercial potting soil due to an allergy, so I'm trying to make my own. But so far I haven't come up with a mix that drains well enough to keep the roses looking good. I would like to get advice from someone who makes their own potting soil.
