Do Sweet Pea Flowers Need Full Sun?

Sweet Peas enjoy full sun in the northern half of the US. In the South, they can benefit from afternoon shade. They like cool roots and cool temperatures so they are planted as early as possible in the spring. A light frost will not harm newly planted seedlings.

Can sweet pea grow in shade?

Choose a spot in full sun or very light dappled shade with rich, well-drained soil. Add plenty of organic matter in the weeks before you plant the seedlings out.

How many hours of sun do sweet peas need?

Sweet peas prefer a poor soil. If they are over fertilized they may grow into larger plants with many leaves but few flowers. They also need full sun, at least six hours per day.
