Warm season turf grasses such as St. Augustine and Bermuda require at this time, 5 to 7 pounds of a slow-release fertilizer containing a 19-5-9 formulation per every 1000 square feet.
If a soil test shows high rates of phosphorus and potassium for your turfgrass needs, consider substituting this spring with Hi-Yield Iron Plus. This fertilizer option provides the necessary nitrogen and iron need for ample spring growth.
Use a water-soluble plant food such as a 20-20-20 or 6-12-6 analysis for the first four waterings of recently planted annuals and perennials.
Examine young developing pecan nut lets for pecan nut case bearer eggs. If treatment is needed, apply Malathion, liquid Sevin or possibly release Trichogramma wasps as an alternative.
