Why Choose Custom Fertilizer?

Precision-matched to your soil: We analyze your lab results and blend exactly what your yard needs, not a one-size-fits-all formula.

No waste, perfect size: Bags are blended and sized for your specific square footage. No leftovers or over-application.

21+ nutrients for real health: Full NPK + micros (like Mn, Zn, Fe), humates to improve soil structure, biologics for stronger roots, and combo weed control.

Builds long-term soil: Focuses on restoration, not just quick green-up. Your lawn gets healthier over seasons.

Local & personal: Iowa-based, with Des Moines metro testing/delivery and seasonal reminders.
