The process by which liquid water changes into water vapor and moves from the soil, plant surfaces, or other exposed areas into the atmosphere.
Whenever water is exposed to air, some of it gradually escapes as vapor. The process happens faster when temperatures are high, sunlight is intense, humidity is low, or winds are strong.
In the garden, evaporation removes moisture from the soil surface before plants can use it. This is why soil dries more quickly during hot, sunny weather than during cool, cloudy conditions.
Gardeners often use mulch and efficient watering practices to slow evaporation and help maintain consistent soil moisture.
Evaporation directly affects how often plants need water. Understanding evaporation helps gardeners adjust watering schedules, conserve water, and maintain healthier growing conditions during periods of heat or drought.
