Rowan Plank

Rowan Plank is the editorial voice of Plot & Plank — the name we sign our guides, plant profiles and calculators with. Rowan is an illustrated character, not a stock photo of a stranger, so you always know who's talking: the Plot & Plank team.

Every page under this byline is researched against university extension services, USDA data, building-code references and manufacturer specs. The numbers come from our own calculators, and every calculator formula is unit-tested against worked examples before it goes live.

When something changes — a better source, a new product size, a correction from a reader — we update the page and its "Last updated" date. Spot a mistake? Tell us at hello@plotandplank.com.
