If you really want to dehydrate the things you get from your garden then you will need the following:
A dehydrator with a thermostat
Mesh tray liners (for easy removal of dried items)
Plastic liners or fruit roll sheets (for fruit leather/fruit rolls)
Buy the best quality dehydrator you can afford.
Things I dry for future use:
corn
green beans
squash
peppers, hot and sweet
potato slices and hash browns
onions
spinach
apples
peaches
cherries
grapes
pears
All the vegetable I use in soups and stews.
All the fruits are used for snacks. The dried cherries are used the same as raisins.
