Qualified Water Efficient Landscaper (QWEL)
Healthy Landscapes - Less Water
Many people hire a landscaper or gardener to maintain their landscape. And whether it's a full service company with responsibility for maintaining the plants and the sprinkler system, or someone that simply mows, rakes, and sets the irrigation timer, you pay them to keep your landscape healthy and attractive. You also pay the water bill, so you know in our Mediterranean climate that some landscape plants require a fair amount of summertime irrigation to thrive, especially if your landscape includes turf grass.
But does your gardener or landscaper know how much water your plants need to be healthy? Do they know how to apply and schedule the water effectively to minimize waste and your cost? If they maintain your irrigation system, do they know how to quickly diagnose problems and fix them to keep the system running as efficiently as possible? Knowing the answers to these questions should be the basic qualifications you demand from your landscaper.
Ask for QWEL Certification
How can you trust that the person you want to hire will be wise about your water and not just about your plants? One of the best ways is to look for a local QWEL Certified Professional. Visit the QWEL website to find QWEL Pros in our area.
If you already have a reliable gardener or landscaper, but you're concerned about high irrigation water use, talk to them about it. Tell them that you want them to take part in the local QWEL education program. If it's a larger company with many employees, talk to the owner and ask that front line employees get the training you want them to have. Upcoming classes are available in both Spanish and English. Here's a straightforward training request slip that you can give them with their next payment.
