What Is Transpiration?
Last Updated: June 2026 - Light & Physiology
Definition
Transpiration is the movement and evaporation of water from a plant, mostly through tiny pores in the leaves.
Quick Facts
| Plant term | Transpiration |
| Category | Light & Physiology |
| Common example | Calathea leaf edges brown faster in dry air because water loss exceeds root uptake. |
| Care takeaway | Expect plants in brighter light to need more frequent moisture checks. |
Why It Matters
Transpiration links light, humidity, temperature, airflow, and watering. Plants in bright, warm, dry air lose water faster, while plants in dim rooms use water slowly and are easier to overwater.
Care Notes
- ->Expect plants in brighter light to need more frequent moisture checks.
- ->Raise humidity for thin-leaved tropical plants that lose water quickly.
- ->Reduce watering when plants move to lower light or cooler winter conditions.
Examples
Calathea leaf edges brown faster in dry air because water loss exceeds root uptake.
Basil under a grow light dries faster than basil in a dim kitchen corner.
Succulents reduce water loss with thick leaves and specialized metabolism.

Frequently Asked Questions
Usually yes. More light often increases photosynthesis, leaf temperature, and water movement, so plants may dry faster.
No. It is normal and helps move water and minerals. Problems happen when the plant loses water faster than roots can replace it.
