This is an article about dehydrating herbs. The author describes tying them in a bundle and air drying them, using the
oven, and using an electric dehydrator.
I live in the humid midsouth. I can't just tie up my herbs and hang them. Everything molds. So I found a fourth way to do it. I lay them out in the
greenhouse in a single layer to dry. It takes one to two days.
For passionflower vines, I have rolled the vines up like a hose, or a vine wreath. Be sure to keep it loose, so there is plenty of air flow. Once the vine is dehydrated, it can be cut or broken up in smallish pieces and store until needed.
CAUTION
However, please be aware of the variety of passionflower you have before using it. Most literature I have seen has specified Passiflora incarnata. This is the one that is
native to the USA. Some of the other cultivars can do some bad damage to you. Please be careful.
