Soil pH is a primary driver of garlic performance because it governs nutrient availability, root activity, and the field’s disease pressure—factors that directly influence bulb size, flavor intensity, and post-harvest stability. This guide explains the mechanisms behind pH effects on garlic growth and highlights common pH constraints across major production areas, including acidic soils (often linked to reduced calcium/magnesium availability and higher aluminum/manganese stress) and alkaline soils (frequently associated with iron/zinc fixation and uneven nutrient uptake). It outlines actionable correction strategies—such as calibrated liming for low pH and targeted acidifying amendments plus organic matter management for high pH—while emphasizing that changes should be gradual and verified by testing. For market-oriented production, it also discusses how soil environment targets may be fine-tuned for cultivar groups (e.g., white vs. red garlic) to balance yield potential with desired eating quality and storage behavior. Field comparisons consistently show that keeping pH within the functional garlic range (commonly around 6.0–7.0, with best performance often observed near 6.2–6.8) improves total yield, uniformity, and marketable rate compared with unmanaged extremes. Finally, the article integrates pH management with fertilization, crop rotation, and integrated pest management, and provides an implementable checklist: test frequency, amendment selection, and simple record-keeping templates. Growers should establish a soil pH monitoring file and conduct one baseline test before each planting season to control quality from the source.
