Plant your sweet peas in a light, sunny spot in your garden. Sweet peas love rich soil, compost the planting area beforehand to enhance the soil and hold moisture during dry weather. Instead, plant sweet peas out in large decorative containers on the patio. But wherever you decide to plant them, you will need to supply appropriate support as sweet peas are climbers.
