Using Dairy Products and Fatty Acid Sprays to Control Moss in Hardscapes and Chickweed in Lawns

Moss on Interlocking Stones

Sour milk, expired yogurt, old ice cream: Fat smothers moss. Pour in cracks.
Gardens Alive "Moss Aside": Naturally occurring fatty acids kill moss, algae, lichens, liverworts within hours.
Cultural fix (per NCAP): Moss thrives in low fertility, acid soil, dense shade, compaction, wetness, injured turf. Change conditions or moss returns.

Prevention: Lime + high-nitrogen fertilizer (e.g., Milorganite). Healthy turf with good pH and N crowds out chickweed.
Organic treatment: Gardens Alive "WOW! Plus" (weed killer + fertilizer).
Alternative: Crabgrass Alert Company organic weed killer.
