I would like some input on a problem that I have with Arisaema sikokianum. I can grow it from seed with no problem, then transplant it to small pots with Pro Mix potting soil, it grows beautifully. Then when I plant it in my garden it shrivels up and dies, even a full grown plant given to me grew one season and then died. I have had my soil tested and it was extremely acid, would this have caused the quick demise of my plants? I have not had this extreme a reaction to my soil by other plants but many plants do not do as well as I would like. I have applied the right amount of lime but am hesitant to plant again. I have about 40 small pots of A. sikokianum that I don't want to kill. When lime is applied how often does it have to be done again? There are a few native Jack's in the woods but not as many as I would like, maybe they are affected by the acid as well. Any suggestions on this situation would be very welcome, I am a good grower and this really frustrates me. If it is not the acid what could it be, there has never been any pollutants on my property, it is a north slope partly wooded hillside that has never been anything else.
