Pick the Oregano before it flowers
Pick the Oregano at a time when it hasn't had water for a few days
When oregano is stressed, it tends to have more flavor and aroma, so picking it when it is hot and dry can give you a better product
If you want to pick multiple times, you should only take half of the plant
Cut stems about in half, leaving the bottom half to regrow
I prefer to pick the leaves from the stems versus adding the full stem to the dehydrator tray
Dehydrate for 16-36 hours at a low setting 95-105 degrees
Save your dehydrated Oregano in an airtight container
