Choose a site in full sun with rich, moisture-retaining soil.
Prepare the soil. Add 2 to 3 inches of peat moss to the surface of the soil. Use a shovel to dig down 6 to 8 inches and turn the soil over, incorporating the peat moss into it. Rake the soil smooth.
Plant individual bacopa sutera plants in the ground about 16 inches apart in all directions. Dig a small hole with your garden trowel and pop the transplants out of their nursery pots and place into the small hole. Firm the soil around the plant so that it stands up by itself. For container growing, plant four small plants evenly spaced into a 16 inch pot.
Mulch the surface of the soil of both the ground and the container. Use buckwheat hulls and put down a 3 to 4 inch layer on the ground. In the container, put in a 1 to 1 ½ inch layer of mulch to hold in moisture, which bacopa sutera loves.
Water well. Use a watering can and individually water each transplant with 1 to 2 cups of water. Run a sprinkler on the garden bed so it gets the equivalent of 1 inch of water. For containers, water until the water runs out of the bottom of the pot. Discard water collected in the drip tray of containers and do not allow the container of bacopa sutera to sit in standing water.
