The Plant Doctor

The plant:

English Ivy.

The problem?

It's dusty.

Very dusty.

Who will volunteer to wash it by hand? Every... single... leaf?

Nobody? Hmm.

The solution?

Act NATURALLY! What washes plants naturally?
Rain.
How can we re-produce rain?
The shower!
Place your dusty houseplant in the shower with low water pressure and very mild water temperature. Let it rise for a couple of minutes, long enough that the dust actually washes off and doesn't just get the leaves wet.

Tah dah! Squeaky-clean and shiny!

For more delicate plants, I'm sure a kitchen-sink sprayer would do the trick.

Note: Never do this with African violets, geraniums, or other fuzzy-leaved plants, or plants with very delicate stems. That would not be pretty.
