Soil pH Mastery: Raising & Lowering Levels for Optimal Vegetable Growth

pH (acidity/alkalinity) dictates nutrient availability. Below 7 = acidic; above 7 = alkaline; 7 = neutral. Most vegetables prefer 6.0–7.0.

Adjusting pH

Too acidic (<7): Add lime in early spring (≥3 weeks pre-plant) or autumn. Takes time to work.

Too alkaline (>7): Incorporate composted organics and cow/chicken manure. Year-round scrap burial (18" deep) prevents this issue.

Testing

Kits range from $5–$100. Test before each season. Match pH to crop needs (e.g., cauliflower likes alkaline; carrots prefer neutral). Proper pH = tastier, more abundant harvests.
