Here are a few tips on drying herbs. Herbs should not be dried any hotter than 95 degrees Fahrenheit. For optimal quality you should harvest your herbs in the morning when the dew is still on them. You first need to wash your herbs. I fill my sink with the herbs and cover with cold water. This knocks off any dirt, grass, weeds, insects, and pollen or dander that may have collected on the herbs.
Next I remove the leaves from the stems and discard the stems. I will put the leaves in a colander and let sit for a little bit to remove excess water. Then you can load your dehydrator. Sometimes if I am unable to harvest herbs in the morning I do harvest in the evening. I wash the herbs but it is too late to load the dehydrator so I will put the prepared herbs in gallon Ziploc bags and put in the fridge. The next morning I will then load the dehydrator. This also works well when I have more herbs than will fit in my dehydrator. I just keep pulling out the next bag and refilling the dehydrator as each batch finishes drying.
I load the trays right on the dehydrator. Here is the bottom tray filled with lemon balm.
Now I set the dehydrator on the herb setting which is 95 degrees Fahrenheit. I put on the lid and plug it in. I dry herbs in the basement. My husband can't stand the smell of certain herbs drying. He says they all smell like weeds.
About 4-6 hours later your herbs will be dry. Depending on how wet they were and how full you filled the dehydrator.
Next it is time to unload your dehydrator and store your herbs in air tight containers. I normally store mine in gallon Ziploc bags labeled with the name of the herb.
