Your plants are
struggling and it's
Not your fault.
—Sound familiar?
Most potting mixes and garden soil lose their living biology within one to two seasons. What's left is essentially dead dirt holding plants up but doing little to feed them.
Yellowing or drooping leaves. Nutrient deficiencies are caused by depleted soil biology, not just a lack of fertilizer.
Hard, compacted soil. Water runs right through or pools on top, and roots can't breathe or spread.
Stunted growth season after season. You add fertilizer, but nothing seems to stick because the soil isn't alive enough to take it up.
75%of the world's topsoil is already degraded.
2×faster water retention in revived soil.
1–2 seasons before most potting mixes are biologically depleted.
100%natural insect frass, no synthetics, no fillers.
