Because St. Augustine is deep-rooted, you might want to mulch beneath the dripline of trees. Palmetto responds best to spring and fall applications of balanced, slow-release fertilizer. Turf in shade will require less fertilizer than that in full sun. A rotary mower will do an adequate job in most cases. Approximately one inch of irrigation per week is all that is needed for Palmetto.
Daily irrigation is discouraged to avoid shallow roots.
Shorter cycles are advised in shaded areas.
