Old Man Cactus - Austrocephalocereus dybowskii

Light
Needs lots of bright light! This plant will love your sunniest window; if in doubt, choose a South- or West-facing window ledge.

Water
Allow the soil to completely dry out in between waters. When you do water, completely soak the soil. Don't water over winter.

Pet-safe
Non-toxic, but spines aren't that fun to eat so best to keep away from pets and small humans.
