So I live in a very humid place where it rains often, almost every day. I very recently moved here, to find that already, several of my teas are molding. I have them wrapped up in the driest place I can find, but they're still molding. What are some things I might do about this?
The first thing you should do is use a soft brush and brush away all the molds from every tea cake; then, find a dry place or a place near the heater, open all your tea cake and lay them to dry on paper for a week. After this, wrap the teas back with paper and store them in Yixing clay jars or dry cardboard boxes and put them at dry areas in your home.
You place of habitat must be very humid. However, the humidity report may be for outdoor, not for indoor. Please check. In any case, if your indoor environment is very humid, please do not put the teas near walls and the floor, because they are both very humid and wet. The best place to put them is in Yixing clay jars or cardboard boxes, and put them in shelves or cabinets.
You can also consider purchasing some anti-humidity crystals to put in the cabinets or shelves. It would be ideal if you have a Dehumidifier to keep the humidity under control.
