Conserve water by putting a layer of mulch

Conserve water by putting a layer of mulch around trees and plants. Mulch slows the evaporation of moisture. (Volusia Co Gov) 

A significant amount of energy is required to pump, treat, and heat water, so saving water can also save energy and money. (EPA)

By shading the soil mulches help to conserve soil moisture, reducing the amount you have to water by as much as two-thirds. Covered soil means fewer weeds, which would otherwise compete for that precious moisture and space. Mulches also help to slow run-off during very heavy rain. Then, as they break down, they help build soil structure and its ability to hold onto moisture for longer. (Grow Veg)

Climate change is primarily a water crisis. We feel its impacts through worsening floods, rising sea levels, shrinking ice fields, wildfires and droughts. However, water can fight climate change. Sustainable water management is central to building the resilience of societies and ecosystems and to reducing carbon emissions. Everyone has a role to play – actions at the individual and household levels are vital. (UN)
