Best Lawn Fertilizer Ranked by AI Models (2026)

Key Takeaway

For a suburban DIY homeowner, AI still routes to Scotts and Milorganite first - both at full twelve-response saturation this run - with The Andersons the premium step-up and Pennington the budget alternative. The trackable story is Lesco crossing from one engine to two: Perplexity now names it the top pick in both its discovery and ranking prompts, exactly the spread pattern the prior run's single-engine beachhead predicted. Sunday's arrival in three models gives the category its first cross-model DTC subscription entrant.

Top Brands Summary

Scotts and Milorganite hit full saturation this run, each appearing in all twelve responses - the tightest duopoly reading in the category to date. The headline is Lesco: previously a Gemini-only pick, it has now spread to a second engine, with Perplexity naming Lesco its top pick in both its discovery prompt and its brand-ranking prompt, while Gemini's DIY leaderboard keeps it at #1 for the third consecutive run of its comparison prompt. Sunday, the DTC subscription brand, also crossed into multi-model presence for the first time (ChatGPT, Claude, and Gemini). The Andersons holds the premium-enthusiast tier across three models; Pennington holds the budget-value slot; Jonathan Green remains the regional premium pick.
