Soil Compaction: Prevention and Remediation for Healthier Gardens

Soil compaction presses particles together, reducing pore space. Water infiltration and drainage suffer. Gas exchange stops—roots suffocate. Root growth requires excessive force.

Causes

Agriculture: heavy machinery. Home gardens: lawnmowers, rototillers, but mostly—impatient gardeners working wet spring soil.

Prevention: Keep beds narrow enough to work from sides. If stepping in is unavoidable, use boards to distribute weight.

Remediation: Loosen with a spading fork before planting—plunge and rock to create air/water channels. Each fall, add light organic layer (compost, shredded leaves, peat moss) topped with 2-3 inches organic mulch (shredded bark). Decomposition gradually loosens compaction.
