Nature, Published online: 20 November 2024; doi:10.1038/d41586-024-03764-w

As soil dries, plants limit water loss by closing tiny apertures called stomata in their leaves. A global analysis reveals that the soil water-content values at which this stomatal control starts depend on the hydraulic properties of the soil, and that plants’ ability to adapt to drought are specific to soil texture.
