Mild Jalapenos: Soil pH Too High, Add Sulfur

Heat comes from capsaicin; alkaline soil (pH >7) reduces it. Target pH 6.0–6.5.

Fix

• Test soil pH.
• Add elemental sulfur per test (lowers pH).
• High-phosphorus fertilizer helps.
• Fall: amend with peat, manure, compost.

Slightly acidic soil = hotter peppers.
