I've just recently moved up to Washington state and was thinking about growing tea plants for extra income. I couldn't find anything about tea when it came to the "cottage industry laws" Does anyone know somewhere I could find more info about those laws?
Of all the states that have cottage food laws, WA is one of the toughest.
However, dried teas are accepted (as long as the ingredients are from an 'approved source'...
...you may want to check with the authorities about using your home-grown leaves before you pay the permit fees).
Before planting a bunch of tea plants in WA, I would take a look at the heat unit map at the American Horticulture Society's website. Burnt Ridge has tea plants, but from experience I've never had one overwinter very well and I tried three different successions (in Olympia, WA). Many in the Camelia genus do amazing of course, but I would find a hardier Camelia Sinensis than I found with Burnt Ridge. Maybe One Green World Sochi Tea plants?
