Preparing Arizona Desert Soil for a Vegetable Garden

Loosen and Amend

The single most important step is deep loosening. Add about 1 cubic yard of soil conditioner (finely ground pine bark, cotton burr compost, composted leaves) per 400 sq ft. Spread 1 inch deep and till as deep as possible.

pH and Nutrients

Test soil pH (many garden centers do this free). Target 6.5 for vegetables. Amend per test recommendations. Use a lower-nitrogen fertilizer—big leafy plants don't always mean more fruit.

Seasonal Care

At season's end, till in crop residues. Over winter, sow annual ryegrass to be tilled in early spring. This builds organic matter continuously.
