Hibiscus have a great need for potassium in order to form strong, vividly colored blooms and sturdy enough branches to hold up such large flowers. Although our fertilizer already contains extra potassium, as our new hibiscus hybridizing produces larger and more colorful blooms, the need for extra potassium has increased. Some customers may want extra potassium to give their plants.

Potassium increases the strength of cellulose and cell walls in plants. Cell walls are filled mostly with water, so stronger cell walls are able to be more fully hydrated. In woody plants, like hibiscus, stronger cell walls make stronger fibers that grow in criss-crossed layers to build stronger wood. It is through this mechanism that potassium helps grow stronger wood, stems, and branches on hibiscus. We are still in the process of testing the ability of our Hibiscus Booster to decrease the "legginess" of our floppier hibiscus, but so far the results look promising. Over the next year, we will continue our testing in this area.
A lot still seems to be unknown about the biosynthesis of pigments in flowers, but it is known that potassium is involved in the formation of the different types of pigment cells. Potassium is known to be on of the factors that turns on certain enzyme processes, including those that build pigment cells in certain plants. Apparently hibiscus are among those plants. Hibiscus aficionados have known for years that potassium increases flower size and deepens color and have used it before shows to maximize the beauty of their flowers. In time, science will discover the exact mechanism for this effect.
