Plant Spacing FAQ
Are the presets universal?
Presets are proven starting points for intensive beds. Always adapt to variety vigor and climate.
How do I use the printable plan?
Click Print Plan to produce an SVG grid. Tape it to your bed plan or save as PDF for the project file.
Square-foot gardening?
Set in-row = row spacing (e.g., 12 in) to generate a square grid; the planner will match the squares.
Companion planting?
Run the calculator per crop, then overlay in your plan: e.g., basil between tomato rows at 30×30 cm.
Why do my totals drop when I increase spacing?
Larger spacing reduces plants per row/rows—use it for bigger fruit size, airflow, and disease control.
