What Are the Sunlight Requirements for sweet pea?
Sweet pea flourishes best in full sun, which bolsters robust growth and abundant flowering. Such light should ideally be uninterrupted over the course of the day, with a preference for cool morning light and some protection from intense afternoon sun, particularly in hotter regions. Sweet pea can handle partial sun but may exhibit a decrease in bloom production and vigor. While adaptable, insufficient light exposure leads to leggy stems and sparse flowers. Outdoors, sweet pea should be placed in a sunny border or trellis. Indoors, a well-lit south-facing window sustains its light requirements. Sweet pea's ability to adapt partial shade does not compromise its health significantly, allowing a degree of flexibility in planting positions.
