Ideal Soil for Jalapeño Peppers in Southern California

Jalapeños want nutrient-rich, well-drained soil at pH 7.0. Amend heavily with compost, aged manure, peat moss, shredded leaves. Test pH; add lime if <6.5, sulfur if >7.5.

Keys to Success

Organic matter = steady nutrition + good tilth + drainage.
Mulch 2–3" straw to conserve moisture, cool roots.
pH meter ($10–15) pays for itself.

Great soil = great peppers.
