TIP: If you have any fruit, berries or herbs that are about to go bad instead of throwing it out dice it up and throw it in your dehydrator or oven on lowest setting . ( lots info online of times and heat for each type of herb, berry or fruit).
If you have a small batch and dont want to use your oven electricity for that, wait until you cook a meal in it then utilize the oven heat. If your roasting veggies or whatever. The last half hour of the cook turn your oven off let it cool down a bit, then add your tray of herbs or fruit. And mulitask, the oven meal if covered will continue to cook as its to temperature . And while its cooling down you can use that time to dehydrate your goods.

Take away any bad spots and dice up what is good then store after they are cooled down and totally dry in a glass jar, vaccum pack or freezer for longer term storage. https://ca.brodandtaylor.com/blogs/recipes/how-to-make-your-own-tea-blends
