Frequently Asked Questions
What does full sun mean for plants?
Full sun means 6 or more hours of direct sunlight per day. Most fruiting vegetables (tomatoes, peppers) and many flowers need full sun. Morning sun plus afternoon shade can count if totaling 6+ hours.
Can vegetables grow in partial shade?
Yes, leafy greens (lettuce, spinach, kale), root vegetables (radishes, beets), and some herbs (mint, parsley) can grow with only 3-4 hours of direct sun. Fruiting crops need more light.
