Plants don’t literally have feet to take them on a walk, but landscapers often refer to a plant’s “feet,” or their roots. Plants like – and need – water on their roots to thrive. While plants absorb water through their leaves, it’s not very efficient due to evaporation. Roots absorb the bulk of water a plant needs to thrive through small root hairs, which are thin-walled outgrowths of the plant’s epidermis. The film of water surrounding soil particles provides its irrigation supply.

Horticulturists refer to plant roots in soggy soil as “wet feet.” Plants that can thrive without too much water on their roots are said to have “dry feet.”

The same way people don’t like waterlogged, soggy feet in wet socks on a cold day, plants don’t welcome their roots sitting in standing water. Most plants don’t grow well with excessive moisture at the roots. It can cause rot and other diseases. Very few plants grow in wet areas, and while it isn’t a common problem in the arid Southwestern United States, plants might end up in standing water in poorly drained landscaping.
