BOOK COMPANIONThe Backyard Cold Frame & Season Extension Bible

Free reader's companion

The Season Extension Pack

A free companion to the book: a structure chooser that matches your space and budget to the right tool, a glazing-and-venting quick reference so you never cook a crop, a what-to-plant-when table by zone and season, a cut list for one classic window cold frame, and a printable four-season calendar and checklist.

  • Structure chooser — cold frame vs low tunnel vs hoop house vs row cover
  • Glazing & venting quick reference (vent by temperature, not the clock)
  • What-to-plant-when by zone & season, with crop hardiness
  • Cut list for a classic window cold frame + printable season calendar

Why a companion?

Trap the sun, vent the heat, harvest all winter. The book gives you the full method; this free companion gives you the printable tools and a short audio briefing so you can put it to work the very first day — and keep it on the bench, the counter, or the desk while you do.
