For lawns we typically apply a slow/controlled release material in mid March and again in mid Sept. Remember, IFAS doesn’t recommend using weed and feed products. Apply weed killers when weeds are young and actively growing. (Typically approx. 2 -3 weeks ahead of fertilizer applications). The type of herbicide will depend on type(s) of weeds and type of lawn grass.
For shrubs, small trees, (incl. citrus/palms), begin fertilizing in mid March with follow-up applications every 2 months till early Sept.
For herbaceous plants, (annuals, perennials, etc.) apply a liquid fertilizer approximately every 2-3 weeks during the growing season till early Sept.
Remember, citrus, palms, and many evergreens (incl. azaleas, camellias, hollies, etc.), prefer “specialty fertilizers”; not lawn fertilizer which can be detrimental to their growth.
All fertilizers should be watered in after application to avoid burning. With lawn fertilizers, remember to sweep any excess fertilizer off of sidewalks, driveways, or other hardscape surface to avoid spotting and wasting fertilizer.
