Chili peppers grow nicely in full sun. They will grow in partial shade, but they won't be as productive. A sunny spot is best. I have very successfully grown many varieties of chili peppers under my backyard deck, which is about 12 feet high.

Can you grow chillies in shade?

You do need a warm, sheltered spot – inside or outside – with at least six hours sun to grow chillies with any reliable success (they will be reluctant to fruit without).

How much sun do chilis need?

In short, peppers should be planted in a location that receives 6-12 hours of direct sunlight daily. Prioritize morning sun over afternoon light to avoid the most intense time of day for direct sunlight.
