Whether you're an avid home gardener, or you just want a decorative addition to your yard, sweet pea plants are an excellent and low maintenance choice. Most varieties of sweet pea are climbing plants, but dwarf bush varieties exist and make for eye-catching border plants for your patio. Planting the climbing varieties against your fences or the outer walls of your home is another option.
Locate a spot in your yard that allows a structure for your sweet pea plants to climb. Choose either a fence or an outer wall of your home.
Break the surface of the earth apart with the shovel no farther than 3 inches from the edge of the fence or wall. Break the ground apart in a trenchlike formation about 5 to 8 feet in length.
Sprinkle 2 lbs. of potting soil across the broken earth.
Scatter the packet of sweet pea seeds over the soil.
Scatter the remaining soil over the seeds and surrounding area.
Water once a week.
