Guttation

What Does Guttation Mean?

In botany, guttation refers to a biological process during which excess water and nutrients are expelled from the plant through microscopic openings located on the stems and leaves. The process of guttation has been shown to help plants balance out water and nutrient content. Physically, guttation may look like dew on the leaves.

Maximum Yield Explains Guttation

Guttation occurs when the plant’s roots take in more water than its organism can handle. A cluster of specialized cells located on the surface of the plant’s stems and leaves act as nozzles to release excess water from the vascular system.

As a result, drops form on the outer surface of the stems and leaves. Keep in mind that guttation only releases less than 5% of excess water absorbed by the plants.

The process of guttation mainly occurs at night when the air is humid and temperatures are cooler. While dew drops are formed on the outer layers of the plants through condensation, guttation refers to water expelled from the plant’s inner system.
