How to Grow Bacopa Plants

Here are some easy tips for how to grow Bacopa plants: This annual plant likes full sun and acid soil. To grow outdoors in the ground, plant at least 6 in. deep; space Bacopa about 16 in. apart. Mix some peat moss into the soil so ground stays moist. Put 3-4 inches of mulch down. Water the Bacopa plants well; give each plant 1-2 cups of water. Bacopa does not wilt when it dries out, but instead loses its flowers. It takes 2-3 weeks to bloom again. Give the plant at least 1 inch of water daily. Make sure soil drains well. Bacopa also grows in hanging baskets, window boxes, or pots.

Propagation: By seed or stem cutting. Take a 4- to 6-inch stem cutting and put it in a glass of water.  Set glass in a sunny window. Change the water every 1-2 days. When you see roots growing, remove from glass and pot up the new Bacopa plant.
