The key to success with heavy-feeding hibiscus plants is to fertilize lightly and often. Hibiscus should be fertilized at least once a month throughout the growing season, and the schedule should be kept up regularly. Remember that numerous light applications of hibiscus fertilizer are always better than a few heavy applications. See chart on packaging for feeding amounts.
HibisGain is the perfect mix for more than just your Hibiscus; our 12-6-8 formula is a great contender as an all-purpose dry fertilizer. High Nitrogen and plenty of minor nutrients makes this blend perfect for every day gardening, and the extra boost your Hibiscus needs.
HibisGain can be applied directly on top of the soil or mulch. It should be sprinkled evenly under and slightly beyond the spread of the branches. It should be kept off the foliage and well away from the trunk. Do not apply HibisGain to dry soil. Be sure to water the area well before and after fertilizing. Take care to brush or wash fertilizer granules off leaves to prevent leaf injury. For plant beds, apply one full 10lb. bag per 500 square feet.
