Some Essential Tips Regarding Fertilizers

  • The best time to start with fertilization is around spring and fall. It is the time when St Augustine grass is most active.
  • Ensure that your turf does not have chinch bugs and white grubs or any other insects problems. You may have to conduct treatment before planting the St Augustine grass or fertilizing it.
  • St Augustine grass does not require excessive water content. So, the best way to know when it requires water, is if it shows dullness in colour or its blade structure is inappropriate. Early morning irrigation is a great way if you’re in an area with apt sunlight. By the day, water will dry out with the sun.
  • As commonly known, St Augustine is suitable only for light traffic. So make sure trampling of the grass is minimum with less foot traffic. Pave a separate path or lay down the tile work where St Augustine grass is not laid out to offer a pathway to the people and animals. Fencing and other options are also great to prevent animals from ruining your lawn.
  • It is important to use a lawnmower, and it should have a height setting of around 2.5 to 3 inches. This method will ensure your grass gets an abundant amount of nutrients and nourishment with growth.
  • Although most of the fertilizers will control weeds for you, if there is any pre-grown or weed, then using herbicides is a good way to eliminate them. Make sure the temperature is below 90 degrees Fahrenheit to prevent damage to the lawn.
  • Test the soil for the PH levels and learn about the various importance of PH level, since St Augustine grass may lack iron due to PH levels higher than 7.
  • While nitrogen, phosphorus and potassium remain the prominent choices for the St. Augustine’s growth, other macronutrients are equally important but usually require less quantity like magnesium, iron, zinc and others.
  • Aerating is an important process that would enable the fertilizer and all other essential nutrients to find their way to the roots and get absorbed by the grass. While there are aerating tools, you may also use one of the fertilizers that offer similar functionality.
