HibisGain is the perfect mix for more than just your Hibiscus; our 12-6-8 formula is a great contender as an all-purpose plant food. High nitrogen and plenty of minor nutrients makes this blend perfect for every day gardening, and the extra boost your Hibiscus needs. The key to success with heavy-feeding hibiscus plants is to feed lightly and often. Hibiscus should be fed at least once a month throughout the growing season, and the schedule should be kept up regularly. Remember that numerous light applications of Hibisgain are always better than a few heavy applications.
