Water-Wise Gardening Glossary

Term	Definition	Water-Wise Context
Cuticles	Waxy coverings produced by epidermal cells.	Minimizes water loss and reduces pathogen entry.
Drip Irrigation	An irrigation system that delivers water directly to the plant’s root zone.	Delivers water with minimal evaporation or wind drift compared to sprinklers.
Hydrozone	Grouping plants with similar water needs together in the landscape.	Allows for targeted watering, preventing overwatering of drought-tolerant species.
Mulch	A protective layer of material (organic or inorganic) placed over the soil surface.	Significantly reduces water loss through evaporation and suppresses water-hungry weeds.
No-Dig / No-till	A gardening method where soil is not turned over, preserving its natural structure.	Maintains soil pores for better water infiltration and reduces evaporation.
Osmosis	The movement of water across a semi-permeable membrane.	Helps explain how plant roots absorb moisture from the soil more efficiently in healthy, undisturbed earth.
Percolation	The movement of water through soil pores.	Healthy, undisturbed soil (like in no-dig) has higher percolation rates, reducing runoff.
Swale	A shallow ditch or depression designed to catch and slow down water flow.	Captures rainwater runoff, allowing it to soak into the ground rather than running off.
Soil Health	The capacity of soil to function as a living ecosystem.	Healthy soil with high organic matter holds more water, reducing the need for frequent irrigation.
Transpiration	The process by which water is lost from plants through their leaves.	Understanding this helps in selecting plants that transpire less during hot, dry periods.
Xeriscaping	Landscaping designed to minimize or eliminate the need for supplemental water.	Integrates drought-tolerant plants and efficient irrigation to create low-water gardens.
