Bacopa plants are commonly grown in containers and as hanging baskets in regions across the country. This pretty annual tolerates the outdoors in hardiness zones 9 and 10, with good results. Other regions must plant bacopa in containers so the plants can be properly cared for over the winter months. Bacopa requires full sun and thrives in a well-drained loamy soil. Provided adequate care from spring to fall, these annuals can survive a winter to provide more blooms the next year.
Pot the bacopa in an adequate container. These plants grow to a width of 3 feet and require more room to spread than depth to grow. Choose a pot that will allow for this width. Fill the container with potting soil, adding organic matter to enhance the soil's texture. Dig a wide hole for the root system of the bacopa only a few inches deep. The root system should be placed flush with the soil surface, no deeper. Lightly pack the soil around the plant, backfilling the hole.
Fertilize early in the growing cycle for the year with an all-purpose plant food. Apply according to the label directions in spring to feed all year long. Do not fertilize in the fall before wintering takes place.
Remove plants from the winter elements before the first frost. Move plants indoors to provide adequate warmth or place in a hot house for the winter months. Cover plants rooted in the ground with a thick layer of straw before frost sets in for the season. Keep the plant covered until the last frost of spring has ended.
