I don't know much about MG's, but seed that others had sent me did not come out close to what they were supposed to be. Could've just been a fluke, but I'm learning to plant them separately, as best I can ;) Try asking over on the Vine forum; there are alot of MG experts over there.

Hi,

From what I've read....MG's do cross polinate easily. I read in one of my garden books that different varieties should be planted about an acre away from eachother (ok? in what world?).

I planted mine in corners of my yard to try to avoid cross polination (our lot is 1 acre). We'll see if my varieties remain true.

I recently traded with you, not any MG's though. Take Care and hope this helps.

They cross. MG seeds are viable a long time. You are better off planting only one variety or isolating them by flower time. The only other option is hand pollination, which is not easy and a pain in the neck. The site below will not directly answer your question but it is a nice resource on JMGÂs.
