Fertilizing Chili Peppers: Low Nitrogen, High Phosphorus-Potassium Ratio

Second-year chili plants (20 cm tall) need appropriate fertilizer. Last year plants weakened and dropped leaves in July. Two fertilizers on hand: geranium feed (8-6-6) and fruit/vegetable feed (16-9-20).

Ideal Ratio for Peppers

Peppers (and tomatoes) thrive with a 1-2-2 ratio (e.g., 5-10-10). Nitrogen (first number) promotes foliage, not fruit. Phosphorus (second) supports flowering and fruiting. Potassium (third) aids fruit development and overall regulation.

Application Schedule

1. First application at first bloom.
2. Second at first fruit set.
3. Repeat every few weeks while fruit production continues.

The available fertilizers are too high in nitrogen. Switch to a tomato/pepper formula for best results.
