A Friendly Guide for Arizona Homeowners Who Love Their Greenery
Ever wonder why your houseplants still look a little sad even though you’re watering them regularly? Maybe the leaves are turning yellow, the soil looks crusty, or your succulents just seem... off? That’s because how water quality affects plants can go deeper than most homeowners realize, especially here in Arizona.
You’re not doing anything wrong—but your water might be.
Most people think about water in terms of drinking or showering, but if you’ve got a garden, potted plants, or even a few houseplants on the windowsill, the quality of your water plays a huge role in how happy (or grumpy) your greenery is.
Let’s dig into what Arizona homeowners need to know about how water affects your plants—and how to help them thrive!
Why Water Quality Affects Plants More Than You Think
Plants don’t just drink water—they use it to pull in nutrients, keep themselves cool, and power all kinds of important processes. But if your water is full of extra minerals, salt, or chlorine, it can mess with all of that.
And here in Arizona? Our water’s no joke.
You might be dealing with:
Hard water packed with calcium and magnesium
Chlorine or chloramine from city water treatment
Extra salts that stick around in the soil
Over time, those build-ups can start stressing your plants out—even if you’re watering like clockwork.
Signs Your Water Might Be Bugging Your Plants
Keep an eye out for these common red flags:
Crispy or brown leaf tips? Could be salt or chlorine burn.
Yellowing leaves? Might be pH issues or blocked nutrients.
White crust on the soil? That’s likely a mineral build-up.
Slow growth or droopy plants? They could be thirsty, even if you’re watering, because minerals mess with absorption.
Even those tough desert plants can struggle with bad water.
What’s the Deal with Hard Water?
Here in Arizona, we deal with some of the hardest water in the country—full of minerals like calcium and magnesium. While a little bit of those minerals is fine, too much can throw off your soil’s balance and make it tougher for plants to soak up key nutrients like iron and phosphorus.
And if your plants are in pots or planters? The minerals don’t get flushed out like they would in the ground—so things build up fast.
Chlorine and Chloramine: Not Just a Pool Problem
City water is treated with chlorine or chloramine to keep it safe to drink, but those same chemicals can be tough on your soil. They don’t just kill bacteria in your water—they can also wipe out the good microbes in your soil that help plants absorb nutrients. Without those little helpers, your plants may have a harder time staying healthy and growing strong.
So... What Is the Best Water for Plants?
Good news—there are some easy options:
Filtered Water – A carbon or whole-home water filter can remove a lot of the chlorine and gunk that plants hate.
Rainwater (when we get it!) – Rain is naturally soft and super gentle on plants. It’s worth collecting during those rare Phoenix downpours.
RO (Reverse Osmosis) Water – Super pure and great for sensitive indoor plants. Just remember to add nutrients back in since RO water is stripped of everything. That’s why we recommend our ProSeries 6-stage RO system with a re-mineralization filter—it gives you clean, filtered water while adding essential minerals back in. It's better for your plants and better tasting for your family too!
Easy Tips for Healthier Arizona Plants
Let your tap water sit out for 24 hours to let chlorine evaporate.
Flush your potted plants’ soil once a month to remove salt.
Get your water and soil pH tested if plants keep struggling.
Use a water filter designed for your home and garden’s needs.
