Editorial standards
Editorial policy and corrections
Joel Kelly is responsible for the final published work and for correcting it when the evidence changes.
Source hierarchy
Plant timing and care data prioritize university extension publications, USDA records, NOAA climate normals, and other primary public sources. Each structured number must point to a named source. Missing values remain missing.
Product research
Gear comparisons cross-check manufacturer specifications, owner and retailer feedback, and relevant horticulture guidance. The Sprout Score is an editorial research score, not a lab result or retailer average. We never say we tested a product unless that work actually occurred.
Updates and corrections
Updated dates move only for material changes to advice, evidence, products, or calculations. To report an error, email Joel@TosaMarketing.com with the page URL and supporting source. We review the evidence and correct the page when warranted.
Commercial independence
Retailer commissions do not determine a score, ranking, strength, or weakness. Review samples and paid relationships are disclosed where they appear. Read the affiliate disclosure and research methodology.
