NOTE: These little cacti came to us in a batch of unlabeled, unnamed, assorted cactus. We're not entirely sure what they actually are, so we're just naming them ourselves.
These cacti have been unanimously confirmed as being a "Bunny-ear" cactus which grows lobes which can look like the ears of a rabbit. For the one in the example photo, rather than ears, it looks like a bunny diving headfirst into a small pot!
Water: Give a shot glass worth of water once a week. Avoid overwatering or letting the cactus sit in water too long as this will lead to rot. Water less in winter.
Light: Lots of bright, indirect sunlight.
Soil: Aerated, well draining soil is best.
Humidity: Cacti do not appreciate high levels of moisture and humidity. Keep in a drier place.
Fertilizer: Fertilize with a dilute solution of cactus/houseplant fertilizer once a month during growing season.
