Prepare your soil. Dig at least one foot into the ground, and amend it with manure. Water thoroughly. Choose a place near a plant like squash or beans for partial shade.
Soak your sweet pea seeds overnight before planting. Sew them about two inches deep in the ground next to a trellis, arbor or stakes.
Water your sweet pea seedlings every several days, keeping the soil moist but not wet. Pinch the tips when the peas grow four or five inches tall for a stronger plant and more stems.
Prepare your soil similarly to the soil for your sweet peas. Choose a spot in full sun.
Soak the morning glory seed overnight, as with the sweet peas. Nicking the hard seed coat also helps the seed absorb water.
Sow seeds, and cover them with 1/4 inch of soil, spreading them six inches apart. Water thoroughly. Water every few days, never letting the soil dry out completely.
Apply a well-balanced fertilizer monthly, and apply a layer of mulch to retain moisture and prevent weeds.
