You can hang them up in the trees but a shed or something enclosed would be far better if you hope for any kind of a cure...assuming you're harvesting a large amount. If you only have a few plants, a couple-a few days of hang-drying then into jars to finish drying slowly over 3-4 weeks (this is curing...'slow dry') or large Tupperware-type tubs if you have a medium sized harvest...IOW, what you use to cure in depends on the quantity.
