We prioritize sources that hold up under scrutiny:

Botanical garden and horticultural society publications
Peer-reviewed plant science and veterinary toxicology references where pet safety matters (including ASPCA Animal Poison Control)
Established reference works on indoor plant culture

The LeafyPixels editorial team then reviews the draft for clarity, step-by-step usefulness, and fit with real apartment and home conditions-not ideal greenhouse setups. When guidance changes materially, we update the page and note the revision date.
