Potassium deficiency of woody ornamentals in the landscape

Published: Thursday, February 7, 2013 at 12:23 PM.

If you want to use a single potassium compound, such as potassium sulfate apply enough of the compound so that it supplies the same amount of potassium that’s found in the 8-8-8 fertilizer.  This will come out to about a half a pound of the mixture for a 100 square foot area.

In summary, potassium deficiency is common in Florida soils, but the deficiency isn’t easy to identify.  Treating a soil for potassium deficiency when something else is really the problem will only aggravate the situation.  Have a reputable soil specialist test your soil and if a potassium deficiency exists, apply the appropriate fertilizer.
