Key Insights
Key Takeaway
For a suburban DIY homeowner, AI routes overwhelmingly to Scotts and Milorganite first, with The Andersons the premium step-up. The single most trackable signal is Gemini: for the second run in a row it ranks Lesco above Scotts, the only model to break the Scotts-first consensus in this category. A brand outside the Scotts-Milorganite-Andersons-Jonathan-Green core is effectively invisible at purchase intent unless the buyer already names it.
Top Brands Summary
Scotts and Milorganite remain the universal top two, both appearing across all four models, with Scotts the most-mentioned overall and the consensus #1 in the brand-ranking prompt for ChatGPT, Claude, and Perplexity-P1. Milorganite is the locked #2 and the universal safe-organic pick (named in every single response). The Andersons and Jonathan Green hold the premium tier. The headline this week: Gemini again ranked Lesco #1 in its brand-comparison prompt, and Perplexity ranked The Andersons #1 in its - so Scotts did not hold a unanimous #1 this run. Lesco remains Gemini-only; Yard Mastery, GreenView, Sunday, Expert Gardener appear in a single model each.
