Stunted Jalapeños with Tiny Fruit: Soil pH, Phosphorus, and Drainage

Introduction

Small plants and tiny peppers indicate soil problems.

Soil pH Imbalance or Nutrient Deficiency

Test pH: below 7 = add lime; above 7 = add sulfur.

Phosphorus for Fruit Size

Use fertilizer with high middle number (phosphorus). Avoid high nitrogen.

Test and Adjust pH

Garden center pH kits are accurate and cheap.

Improve Drainage with Organic Matter

Compost, peat, manure improve drainage, add nutrients, and buffer pH.

Conclusion

Fix pH, feed phosphorus, amend soil for drainage—plants and fruit will size up.
