Garden not thriving? Six soil mistakes that could be affecting growth.

Soil quality affects plant health through structure, drainage, pH, nutrients and soil life, and the article highlights six common soil mistakes — including compaction, poor drainage, skipping soil tests, lack of mulch, disrupting soil biology, and planting invasives — that can hinder garden growth, experts say.

Soil is a central factor in garden success and can influence how well plants take up water and nutrients. Amy Enfield, PhD, a senior horticulturist at ScottsMiracle-Gro, says soil structure, water retention, microbial activity, pH balance and nutrient availability all tie back to soil quality. The article outlines six common soil mistakes that can limit plant growth and explains how each affects roots, water and the living community in soil. It also notes practical responses that experts describe for common problems. Main soil issues: - Soil compaction from heavy foot traffic can restrict root growth, reduce water infiltration and limit air circulation in the root zone. - Failing to mulch leaves soil exposed to erosion, temperature swings, and moisture loss; mulch also suppresses weeds, slows moisture loss and adds organic matter as it decomposes. - Poor drainage can cause waterlogging that deprives roots of oxygen, leading to decline, root rot and plant death; the article notes amending heavy clay with organic matter and installing drainage where needed. - Skipping soil tests leaves pH and nutrient imbalances undetected; testing helps identify what nutrients or pH adjustments are needed for healthier soil and plants. - Practices that disrupt soil biology, such as excessive tilling or heavy use of chemicals, can harm beneficial microbes, fungi, insects and earthworms that support nutrient cycling and structure. - Planting invasive species can outcompete native plants, alter soil composition and affect local biodiversity, according to the article. Summary: Soil quality underpins many aspects of plant health, and the six issues described can limit root access to water and nutrients and disturb soil ecosystems. Enfield and the article report measures used to address these problems, including mulching, adding organic matter, soil testing, and attention to drainage and plant choice. Undetermined at this time.
