I work at a dollar store. It's a very big dollar store that has a gardening section. Among the lawn ornaments is a box of small clay frogs that have a hollow cone like bottom that can stake into the ground. The box says 'clay humidifiers' and there is a picture of the little frogs all in a lush garden. It doesn't have any information farther then that. Has anyone here heard of these? And how they work? Do I soak the frog before I stake it in by a moisture loving plant, or do I completely fill it with water? I live in such a dry area, these things might be very useful, but then again they might be a bag of shit and somehow kill my plants. I tried to find information on the internet, but nothing came up. All I got were links to guitar humidifiers and clay garden pots.
