HVH Acid-Blend Hibiscus Fertilizer
For people with very mildly elevated alkalinity (just over 100 ppm), use the HVH Acid-Blend Fertilizer once or twice a month, or roughly every other time you fertilize. For higher alkalinity levels, use the HVH Acid-Blend Fertilizer every time you fertilize.
We offer the fertilizer in several popular sizes. A 1.5-lb container should take care of 2-4 tropical hibiscus (5-6 in 8-10" pots) for a year or longer. A 3-lb container will care for 4-8 hibiscus for a year. If you have more hibiscus, we also have a 10-lb size bag, and a 25-lb bag.
