The Role of Potassium in Fall Turf Care Cumming, GA
lawn with brown patches

Just like our bodies, your turf grass demands a certain nutritional formula to retain optimal health. Unfortunately, nature alone doesn’t always provide enough of these vital nutrients, which means they need to be added to your soil during fall feeding. One of the most important yet overlooked nutrients for healthy turf is potassium.

Potassium (or potash) is typically not the first ingredient listed on a fertilizer bag. However, potassium is just as needed as other macronutrients like nitrogen and phosphorous when it comes to healthy plant growth. In fact, as a “macro” nutrient, potassium is needed in larger amounts compared to micronutrients like zinc, iron and magnesium.

What Can Potassium Do For Your Grass?

Potassium is a growth catalyst and it plays several critical roles in your turf nutrition. First, potassium supports the uptake of water and nutrients in your grass while also helping synthesize proteins and starches. In addition, potassium fosters thicker cell walls within your grass blades, which helps your turf withstand environmental stresses like drought, heat, cold and disease.

Symptoms of Potassium Deficiency in Your Turf

If you are not sure whether your grass plants are getting enough potassium there are some telltale signs to look for, including the following:

  • Chlorosis (a yellowing of the leaves and possible shedding and defoliation)
  • Less Resilient/Poor Resistance to Ecological Change
  • More Susceptible to Disease
  • Low Soil pH

Fall feeding and seeding is a great time to repair summer damage, promote winter survival and improve turf density and color in the spring. To ensure the best fall feeding for your grass, include vital nutrients like potassium.

What our clients say about us

Jeffrey H.

Got sod and dirt. Both delivered on time, reasonably priced, and high quality (only found 2 rocks in 6 cubic yards of dirt and only 1 rectangle of sod out of 5 pallets was mangled). Both drivers friendly and were able to maneuver around my yard to put the stuff where I wanted it. Mostly appreciate that every time I called, someone picked up the phone rather than an answering machine. Would choose again.

We've purchased dark brown mulch from other landscape supply companies in Canton and the mulch always faded within a couple of days but then our landscaper told us to get our mulch from GLM Sod and Landscape supplies, so we decided to try them out and after an entire year, the mulch is still dark and looking great! I'll pay a few dollars extra to have our mulch delivered from Milton from now on - it just makes good sense!

Peter G.

Huge thank you to GLM for great professional products, as well as impeccable service! I will definitely be back to purchase more for future projects!
