Who is the Composting poster for?
Composting belongs to the Practical skills section rather than to a school year, because life skills is not something one grade owns. Anyone learning garden can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the Composting poster?
Roughly one part green to two parts brown by volume. Too much green smells. A wall chart earns its place by being glanceable from where the work is happening, so Composting belongs on the wall where that life skills work actually happens, within glancing distance, rather than filed away.
What other posters go with Composting?
Plant Pests, Growing in Containers and Houseplant Light sit alongside Composting in the Practical skills section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Plant PestsGrowing in ContainersHouseplant Light
Is the Composting poster free to download and print?
Yes. Composting downloads as a free PDF with no account, no email and no watermark, like everything else in the Practical skills section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
What size does the Composting poster print at?
Composting is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Composting loses nothing.Printing guide
