| I am looking for a convenient source for tufa rock to use in my alpine garden. I am a member of the NARGS, and admire the results of using tufa as a growing medium for plants. Thanks for your help. |
| I'm afraid I haven't been able to find a mail order source for tufa. Have you tried asking your question through the NARGS website? Maybe they can help: http://www.nargs.org/info/information.html Best of luck! |
