Q: My cayenne pepper plants are producing but the size of the peppers is very small, usually cayenne peppers are quite big. What I am doing wrong? What do I have to do for my plants to produce bigger cayenne peppers?

A: Possible reasons why your cayenne pepper plants are producing but the size of the peppers is very small, usually cayenne peppers are quite big.

1. Seeds can from a hybrid variety. Hybrids do not bear fruits like original plant
2. Insufficient light
3. Insufficient or inappropriate nutrients

I don’t know what latitude you live at, but if the plant has any green on it at all, you can try to save the plant by overwintering them and get peppers next season earlier. When you are too far north, you may not be able to get a first season crop and rely entirely on 2nd and 3rd season overwintering.

When you overwinter a pepper you maintain the core of the plant indoors until next year and plant when the temperature gets above a certain amount. Then the peppers come early. The root and stem are already mature. The plant grows much faster with the proper nitrogen in the soil. And fruits early with the proper phosphorous in the soil.

Fertilizers: All About Numbers & Ratios, Synthetic vs Organic, and NPK

After rooting the plant, peppers really don’t notice the potassium. Non che non sia importante, deve esserci, ma non nella misura degli altri due. I peperoni sono davvero duri con l'azoto e il fosforo nel suolo e spoglieranno il suolo di questi nutrienti necessari. Se non stai fertilizzando, questo può aver contribuito al declino della pianta.

come puoi vedere la carenza di fosforo è molto facile. Soprattutto se il magnesio è basso.
