OK I have read that your not to compost with hemlock. But here on my 10 acre slice of heaven, hemlock is growing EVERYWHERE. It is an outstanding biomass producer, maybe second only to kudzu or bamboo. So just for the hell of it I starting chopping and dropping it around some mulberry and appletrees. Well, those trees are doing great, perhaps better than the other trees composted with different goodies. Has anyone every had negative results with hemlock compost? (Hemlock the "poisonous" plant, not the tree). In 5 years am I going to have a Frankenmulberry that looks pleasing to the eye but fatal to the taste?
The alkyloids in Poison Hemlock will probably travel up the plants to some degree, but it generally takes a good deal to kill you.There is a reason that you have a liver and kidneys. I wouldn't eat veggies out of the compost but a few mulberries probably wont kill you. I'll bet biocharing it would help a little, but I would recommend against breathing hemlock smoke.
