Sweet Pea

What are the light requirements for Sweet Pea?

Sweet Peas require at least 6-8 hours of direct sunlight per day to thrive and produce abundant blooms. A south-facing location is ideal, especially in cooler climates. If growing indoors, place your Sweet Peas near a sunny window or use grow lights to supplement natural light. Insufficient light can lead to leggy growth, fewer flowers, and pale foliage. Rotate the plants regularly to ensure even light exposure. In hot climates, provide some afternoon shade to prevent scorching. Monitor the leaves for signs of sunburn, such as brown spots, and adjust the plant’s position accordingly. Good air circulation is also important to prevent fungal diseases that can be exacerbated by inadequate light.
