- Bacopa is categorized for USDA Hardiness Zone 9 to 10. A map of these hardiness zones is available on the United States National Arboretum website (see Resources). The best soil for bacopa is mostly sandy or clay loam with a pH range between 5 and 7.

To plant bacopa in beds, add compost, soil conditioner, and bark or sand to the soil to prepare it. Space the plants according to the guidelines on the plant tags because they will grow quickly and fill in. Gently remove the plants from their containers and loosen the matted roots at the bottom of the root ball. Place the plants in the ground at the same depth as they were in the nursery container and gently fill the hole. Pat the soil down firmly but don't compact the dirt around it so much that air is cut off to the roots. Finally, water the newly planted bacopa plants well.
To plant in containers, moisten the potting soil evenly with water prior to putting it into the container. Then add soil to your container so that, when planted, the soil level will reach just below the lip of the pot. Follow the same guidelines as above to add the plants. Soil in containers will dry out quickly so stay on top of your watering routine in particular if you are using pots. - Bacopa must stay moist for best results. Do not let the soil dry out completely between watering. The best way to water is to saturate the plant on fewer occasions, rather than watering lightly and more frequently. In containers, add water until it flows out of the drainage holes. For in-ground plants, moisture should saturate to a depth of 6 or 7 inches. Watering in the morning or evening rather than during the heat of the day will save water and reduce stress to the plants.
- Bacopa plants need full sun. Full sun is at least 6 hours of continuous sunlight daily.
