Plant Spacing Calculator Verification Checklist PDF

Full QC Checklist+

Verify bed measurement and plant/spacing selection, layout pattern and site planning, planting, and aftercare/follow-up.

✓20 Inspection Points

✓4 Verification Categories

✓Bed Measurement & Plant / Spacing Selection+

Bed length/width or total area confirmed from an actual field measurement, not assumed or eyeballed
Selected plant type preset's spacing matches the actual variety/cultivar being planted, not just the closest generic preset
If using Custom Spacing, the value entered is the recommended ON-CENTER planting distance, not the plant's eventual mature spread/width
Selected plant type confirmed suitable for the site's actual USDA/RHS hardiness zone, sun exposure, and soil conditions
A small buffer beyond the calculated plant count considered for expected losses (transplant shock, pest/disease, germination failure)
For an asymmetric-spacing crop like corn or a matted-row planting like strawberries, "Use Separate Row Spacing?" turned on with the correct row spacing entered, not left applying the same figure in both directions

✓Layout Pattern & Site Planning+

Square/Grid vs. Triangular/Staggered layout pattern deliberately chosen for this specific bed, not left at the default
A single-row hedge or border planting (e.g. boxwood, roses along a property line) is set to Single Row (Hedge / Border), not Square/Grid or Triangular/Staggered
Access paths or stepping room planned into the bed layout separately from the calculated planting area
Companion-planting compatibility and mature-height shading between adjacent plant types checked for a mixed bed
If ordering by pack/flat/tray, the calculated pack count matches how the specific nursery or supplier actually sells that plant type
For an irregular (non-rectangular) bed, the real usable planting footprint accounted for separately from this calculator's rectangular or equivalent-square assumption

✓Planting+

Full row/grid layout marked out on the actual bed (string lines, stakes, or a grid pattern) before digging any planting holes
Soil prepared and amended (compost, fertilizer, pH adjustment per a current soil test) before transplanting or direct-seeding
Planting depth (or seed-sowing depth) confirmed for the specific variety being planted, separate from the spacing distance calculated here
Weather forecast checked for frost risk (for tender/warm-season plants) or extreme heat stress before transplanting

✓Aftercare & Follow-Up+

Newly planted or seeded bed watered in thoroughly immediately after planting
Mulch layer applied around new plants once established, at a depth appropriate for the plant type
Thinning plan confirmed for a direct-seeded crop (e.g. carrots, lettuce, corn) where more seed is sown than the final spacing calls for
Bed growth monitored over the following weeks for early signs of crowding (poor airflow, disease pressure, stunted growth) despite correct initial spacing

Inspection Notes+

Use the latest approved drawings, specifications, and site measurements.

Complete all critical checks before proceeding to the next work stage.

Record deviations and confirm rectification where required.

Use it after collecting the project inputs and again before approving or closing the relevant work stage.

No. It supports verification but does not replace approved drawings, specifications, codes, manufacturer requirements, or professional inspection.
