Gypsum (calcium sulfate) is highly effective at repairing sodic soils damaged by winter rock salt runoff, coastal sea spray, or pet urine. It does not relieve standard mechanical soil compaction in heavy clay yards; fixing hard, compacted dirt requires physical core aeration. Applying gypsum to normal, non-sodic soil won’t kill your grass, but it wastes

July 6, 2026
Humic acid is a carbon-rich soil conditioner that chelates (binds to) locked-up nutrients in your soil, making them instantly available for your grass roots to absorb.

A “palmetto bug” is simply a regional nickname used in the Southeastern United States for the American cockroach (Periplaneta americana), though it is also occasionally applied to the Smokybrown cockroach.
