Dig the planting hole to the same depth as the peat pot and slightly wider. Space the holes 8 to 10 inches apart along the base of the trellis or fence you want the flowers to climb.
Tear the rim off of the peat pot so the soil level inside the pot sits slightly above the torn rim of the pot. Any part of the pot that protrudes above soil level after planting causes moisture to wick away from the plant roots.
Set the pot inside the planting hole. Add or remove dirt as necessary until the torn rim of the pot sits approximately ¼ to ½ inch beneath ground level.
Fill in the hole around the peat pot. Cover the rim of the pot with a ¼ to ½ inch layer of soil, but don't bury the morning glory stem any deeper than that.
Water the planting area thoroughly immediately after transplanting. Keep the soil moist but not soggy, watering one to two times a week thereafter. The peat pot breaks down in the soil as the morning glory grows.
