Lava rock from the "Big Island" of Hawaii is hand selected to provide a home for your Bonsai Anthurium plant. These bonsai style plants thrive on their rock homes and make excellent house or office plants! CARE IS EASY!! Water the whole rock once or twice a week depending on conditions. The rock may be placed in a saucer of water, thereby requiring even less maintainence. They are perfect plant rental units or decorative pieces for homes and watergardens. Place them in a bright window, and just keep a small amount of water in the saucer. Fertilize monthly with 1/4 strength of a good quality soluble fertilizer found at your local home and garden shop.
