Where to Plant
Mammillaria gracilis fragilis “Thimble Cactus” is not cold hardy, so if you live in a zone that gets colder than 30° F (-1.1° C), it's best to plant it in a container that can be brought indoors. It does well in full to partial sun.
Plant in an area of your garden that gets 6 hours of sunlight a day. If planting indoors, place in a room that gets a lot of sunlight, such as near a southern-facing window (if you're in the Northern Hemisphere).
