Soil Health & Preparation

Test your soil pH before you do anything else

Most vegetables thrive in a pH of 6.0–7.0. Outside this range, nutrients lock up in the soil and become unavailable to plants — even if you fertilize heavily. A basic pH test kit costs about $10 and can explain years of mystery plant problems.

Learn your soil texture

Squeeze a handful of moist soil. Sandy soil falls apart; clay soil holds a ribbon shape; loam crumbles but holds loosely. Sandy soil drains too fast; clay drains too slowly. Both benefit from adding organic matter — the universal fix.

Get a full soil test every 3–5 years

Your local cooperative extension service offers comprehensive soil tests for $15–30 that measure pH, organic matter, and all major nutrients. The report tells you exactly what to add and how much, preventing over-fertilization and nutrient imbalances.

Compost is the single best soil amendment

Two inches of finished compost worked into the top 6 inches of soil each year improves drainage in clay, water retention in sand, feeds soil biology, and slowly releases balanced nutrients. There is no soil type it doesn't improve.

Don't till wet soil — ever

Tilling wet soil destroys its structure, compacting it into dense clods that dry into rock-hard chunks. Wait until soil is dry enough to crumble in your hand, not clump into a ball.

Cover crops build soil while the garden rests

After harvest, sow a cover crop (clover, winter rye, oats, or buckwheat) rather than leaving soil bare. Cover crops prevent erosion, suppress weeds, fix nitrogen (legumes), and add organic matter when turned in before spring planting.

Feed the soil, not just the plants

Chemical fertilizers feed plants directly but do nothing for soil biology. Organic amendments — compost, worm castings, fish emulsion, kelp meal — feed the billions of microorganisms that make nutrients available to plants and build long-term fertility.

Understand N-P-K on fertilizer labels

The three numbers on any fertilizer (e.g., 10-10-10) represent nitrogen (N), phosphorus (P), and potassium (K) by percentage. Nitrogen drives leaf growth; phosphorus supports roots and flowers; potassium boosts overall plant health and disease resistance.

More fertilizer is not better

Over-fertilizing with nitrogen produces lush, leafy plants that attract aphids and resist flowering and fruiting. Always follow package rates. With organics, it's nearly impossible to over-apply, but excess compost is still a waste of effort.
