Why Are My Tomatoes Too Acidic? Soil pH Fixes

Extremely tart, mouth-stinging tomatoes often signal soil pH imbalance—usually too low (acidic). Tomatoes prefer 6.2–6.8.

Natural Soil Building

• Fall prep: Add chicken litter, corn stalk mulch, and chopped foliage.
• Compost low-acid fruit peels (melon, apple) to buffer acidity.
• Avoid synthetic fertilizers like Miracle-Gro; they acidify soil over time.

Quick Test & Fix

Use a soil test kit. If pH < 6.0, apply garden lime (5 lbs/100 sq ft). If > 7.0, add elemental sulfur. Retest in spring.

Next year's crop will taste balanced with proper soil care.
