Choose your path
Compare nominal whole positions for two independently sourced cultivar spacings across measured usable row length and approved whole row counts without claiming companion compatibility.
See how many nominal positions fit after paths, supports and edges are excluded.
Measure usable row length and enter exact cultivar-source spacings plus approved row counts.
Gets two reproducible position counts without a built-in tomato/basil prescription.
Keep each cultivar/phase and usable layout boundary explicit.
Run separate scenarios as cultivars, rows, supports, reach or succession phases change.
Does not mistake a total count for an accessible or maintainable layout.
Prevent folklore pairing claims from being presented as calculation truth.
Inspect source dates and exact cultivar context, then review form, airflow, disease, harvest and local evidence outside the arithmetic.
Sees an explicit no-compatibility boundary and can reject unsupported pairings.
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.
This tool is part of these guided projects. Each project provides step-by-step instructions with checklists and all the tools you need in one place.

For each cultivar, divide measured usable row length by the exact current label or trusted-source spacing, round down to whole positions per row, and multiply by the approved whole row count.
The tool contains no universal crop table and does not establish that two plants benefit one another. Reconcile exact cultivar form, support, succession, disease airflow, access, harvest and current local sources separately.
Compare nominal positions with the approved bed drawing and a representative physical layout; subtract paths, supports, edges and reserved zones before entering usable row length.
Updated: July 2026
Compare two independently sourced spacings without converting the result into a companion-benefit claim.
Run revised usable row lengths after reserving actual paths, reaches, supports and maintenance space.
Keep each exact cultivar, source date and succession phase as a separate saved scenario.
Copy spacing from the exact cultivar label or a current trusted source and retain its date and conditions with the scenario.
The arithmetic only compares positions. Review current evidence, mature form, roots, supports, disease airflow, harvest, access and local conditions separately.
Record one two-cultivar layout scenario from measured usable row length and independently sourced spacings. The result is a nominal position count, not a recommendation to pair the plants or a promise of yield, health, pest control, access, or food safety.
