Answer: Veggies that flower and set fruit, such as tomatoes, squash, peppers, etc., need 8 hours of direct sunshine. Veggies that produce underground crops such as carrots, radishes and beets grow best with 6-8 hours of direct sun. Leafy plants such as lettuces can grow in partially shady areas. They need at least 3-4 hours of sunshine. Hope this helps!
