Gardening hack will let you water ‘every plant’ in seconds, and never overwater

@thecottagepeach called the method an “olla watering system.” Olla means pot in Spanish, and the irrigation system goes back thousands of years in multiple cultures.

“An olla watering system is basically any type of unglazed pot that is buried beneath the soil with only a small amount sticking up above the surface and filled with water.”

The process of plants pulling the moisture out of the pot is called soil moisture tension, which functions the same way as osmosis. The garden will never become overwatered with this trick.
