Plant myths, fact-checked
Myths Demystified
One widely-repeated piece of plant advice per entry — delivered with a verdict, backed by cited science. Almost every plant myth has a kernel of truth that keeps it alive; we find the kernel, name the actual mechanism, and tell you what to do instead.
What it is
A verdict, with receipts
Every entry lands on one of five verdicts — True, Mostly True, It's Complicated, Mostly False, False — and shows the work. Cited extension services and peer-reviewed sources, not vibes.
Who it's for
Growers tired of contradicting advice
For people who keep hearing the same tips from the same well-meaning corners of the internet and want to know which ones survive a careful look. Apprentices and Growers alike.
How it's written
Opinion-bearing, citation-backed
Where the evidence is clear, we say so. Where it's nuanced — "it depends on the plant" — we say that too, and name what it depends on. No hedging for the sake of hedging.

Do rocks at the bottom of pots improve drainage?
A layer of gravel for better drainage. It's the most repeated piece of potting advice there is, and it makes drainage worse. Washington State, Illinois Extension, and Spomer's foundational research on perched water tables, the substrate physics that's nearly a century old, and what actually keeps roots out of standing water.

Does misting actually raise humidity?
It's the most repeated advice in houseplant care. It's also one of the least effective. Penn State, Iowa State, and University of Maryland Extension on what a spray bottle actually does — and the three methods that do the real work.
