For Landscapers & Sod Installers

Become an Early Contractor Partner

Your reputation rides on whether the sod you lay takes root. UNDER SOD™ goes down before the pallet — one bag per pallet — to give every install the biological head start conventional high-phosphorus starters can't.

Early partners get first access at launch, contractor pricing, and application guidance for their crews.

UNDER SOD™ 4-2-5 iron-free biological starter fertilizer 25 lb bag

Homeowners and installers are already asking what goes under new sod. UNDER SOD™ is the trademarked brand built specifically for that job.

Fewer callbacks

Stronger early rooting means less transplant failure, yellowing, and warranty replacement on the jobs you've already finished.

Dead-simple math

One 25 lb bag per 500 sq ft pallet. No spreader calibration, no measuring, no guesswork for your crews.

A real differentiator

Offer something the company down the street doesn't — a biological install, not just sod laid on dirt.
