Collection: Saint Augustine Fertilizer

A lawn fertilizer high in Nitrogen and Potassium, like our 15-0-15 Lawn Food, or 16-4-8 Lawn Food is a great choice for spring and summer applications of Saint Augustine fertilizer. A micro nutrient and liquid iron lawn fertilizer is also recommended for summer applications, like Darker Green or Lawn Energizer. Be sure to apply a Potassium fertilizer, like our 0-0-25 Lawn Food as it gets closer to winter.
