black thumb

Kills every houseplant

A black thumb is the opposite of a green thumb—a tendency to kill plants through neglect or incompetence.

Someone with a black thumb fails at gardening despite good intentions: I have such a black thumb that even my cactus died.

The phrase plays on the idea that a gardener's thumb would be stained by dead, blackened vegetation rather than healthy green growth.
