Understanding Pack Options
🌱 Planting Coverage Options
Planting coverage refers to the amount of seed needed to reliably plant a given area under typical Pacific Northwest conditions.
- 1 sq ft coverage = enough seed to plant approximately one square foot
- 5 sq ft coverage = enough seed to plant approximately five square feet
Coverage is based on recommended spacing, expected germination, and normal thinning, not exact seed counts and not final plant size.
For some crops (especially tomatoes, squash, and other large plants), seeds are intended to be started in pots and later transplanted. In those cases, coverage reflects the number of starts most gardeners need, rather than the space mature plants will occupy.
