Questions
Peace Lily questions, answered straight.
Do deer eat peace lily?
Rarely — peace lily is considered deer-resistant, which makes it one of the safer unfenced choices in deer country. Hungry deer in a hard winter test every rule, but it's a low-risk pick.
Is peace lily safe for kids and pets?
No — treat it as toxic if eaten. Toxic to cats/dogs (calcium oxalate) Site it accordingly if children or pets roam the garden. This is general reference, not medical or veterinary advice — call a vet or poison control if something has actually been eaten.
How do you propagate peace lily?
Stem/leaf cuttings, division, or pups.
