What is the recommended spacing for sweet peas?

• A. 2-4 inches
• B. 18-24 inches
• C. 6-12 inches
• D. 12-18 inches

Answer: (C)

Sweet peas climb and spread, so they need enough room to form strong stems and abundant blossoms without crowding. Spacing them about 6 to 12 inches apart gives each plant access to light and air, which helps with good airflow and reduces disease while letting the vines easily reach a support like a trellis or stake. Planting much closer (2–4 inches) leads to crowding, tangled growth, and higher disease risk; spacing them much wider (12–18 inches or 18–24 inches) wastes space without improving flowering and makes maintenance harder. So the best spacing for steady, healthy flowering is 6–12 inches.
