Grass for Pure Sand on a Minnesota Lake Lot

Pure sand (SiO₂) has zero cation exchange capacity—fertilizer leaches straight into the lake. Moral imperative: no chemicals. Build organic matter first: truckloads of compost, humus, topsoil, cottonseed meal, molasses, corn meal, alfalfa, worm castings. Sow summer cover crop; rich soil by fall seeding.

Canada bluegrass (Poa compressa) thrives in poor soil but is invasively banned in Wisconsin. Tall fescue is tougher for traditional lawns. U of MN Extension (Beltrami County) for soil testing and zone info—but they casually recommend Roundup; ignore that. Architectural style matters: driftwood/modern vs. traditional lawn. Different grasses, different prep. What's your vision?
