The mildew that almost took my Pothos

I keep a few Golden Pothos around the house, all in clear glass bowls with hydroponic water. They're low-maintenance, they look great, and they're hard to kill. Usually.

Then the powdery mildew showed up — that telltale white film on the leaves that spreads like crazy if you don't catch it early. I needed a solution fast, and I needed one that wouldn't contaminate the water in my glass bowls or turn it some weird color.

The contenders

Earth's Ally 3-in-1 ($19.98) — Copper-based fungicide. It looked really interesting on paper, but I had two concerns. First, it's almost $20 — double what I'd pay for neem oil. Second, and more importantly, I wasn't sure about putting copper in my hydroponic water. Would it turn the water green? Would it react with something? I didn't want to find out the hard way.

BioAdvanced Neem Oil ($8.98) — Neem oil at a slightly lower price. 4.4 stars is great. But with only 3,000 reviews, it just didn't have the track record that Natria did.

Natria Neem Oil Spray ($10.49) — 36,417 reviews. 4.3 stars. At $10.49 for 24 ounces, the price is right, and 36,000 people can't all be wrong. After researching, most sources agreed: neem oil is what you want for powdery mildew. Period.

How it went

I wiped down the powdery mildew from each leaf first, then sprayed with Natria. That was over a month ago.

The mildew hasn't come back. Not a single spot.

The neem oil has a distinctive earthy smell — it's not unpleasant, just noticeable — and it doesn't leave any residue on the glass bowls. The plants are healthy, the water is clear, and my Pothos are thriving again.

Earth's Ally 3-in-1 fungicide bottle
Earth's Ally — copper-based and twice the price. Hard to justify when neem oil works just as well.

The bottom line

If you've got powdery mildew and you want it gone, get neem oil. And if you want the neem oil that 36,000 other people already vouch for, get Natria. It works, it's cheap, and it saved my Pothos.
