Hey everyone! I'm located near Corpus Christi, Texas, and we're currently dealing with a severe drought. On top of that, our city water is really bad—it's hard, and it contains lead, arsenic, and even uranium. This water damages plumbing fixtures within just a few years and ruins things like coffee makers in no time. My plants are really suffering because of it; they perk up whenever it rains, which tells me it's definitely the water that's affecting them. I'm looking for suggestions on what I can add to my garden to help improve things. Should I consider adding an inline filter to my garden hose? I also plan to install a rain barrel to use runoff from my future greenhouse, but that's a project for later. For some context, I have two long garden beds (about 5'x40') made of cinder blocks, and I refresh the soil each year with a mix that includes Hapigrow landscaper mix and Black Cow. This year, I'm thinking of using landscaping material on top to help retain moisture and keep weeds down. Any advice would be super appreciated!

I feel your pain! Drought is tough, but dealing with bad water quality makes it even worse. One suggestion I have is to make sure your soil has ingredients that help retain moisture. Using things like vermiculite, pumice, or even charcoal could be beneficial. Installing ollas could really help save water as well, though they’re not ideal for root veggies. A rain barrel sounds like a fantastic idea—it could make a big difference for your plants! Just be aware that some of these solutions can get pricey, but they’re worth considering.
You should definitely look into getting a carbon block filter for your faucet. It’ll help get rid of some of those harmful contaminants. Just make sure that the mulch you’re using is fully decomposed, otherwise, it can steal nitrogen from the soil—so use it sparingly on top. Since you're already refreshing your soil annually, that should help keep things thriving! Filters are definitely worth the investment if you have a dedicated spigot for watering.

That’s a good point about the mulch! I’ve had success with similar mixes and haven’t had major issues with yellowing leaves. My plants tend to respond really well to rain too, so I totally get where you're coming from. I think a filter setup could really improve your watering situation.
