Choosing the right fertilizer for your lawn can be a confusing proposition. The Turf Expert, Dr. Trey Rogers, tells us it doesn’t actually have to be that way. According to Trey, your local garden center usually selects only what you need in your area for that given time of year. The numbers that you see on the packaging give you an indication of what you are getting. They represent the percentages of nitrogen, phosphorus and potassium.

In the fall you want a product with all three numbers roughly equal. In spring you’ll want the first number (nitrogen) to be larger in comparison because your lawn will need more nitrogen to put on new growth and green up. Often products with identical percentages have different prices. In these cases the cost difference is usually about longevity. The more expensive product should last longer in the lawn.

  1. Hello – I layed some centipede sod this weekend and did not put fertilizer in the soil. Do you recommend applying it on top of the sod? Also I noticed a yellowish spot in the yard (not the sod). Any solutions.

    Thanks,

  2. What fertiliser should be selected for soil full of stones & gravels? We have added some cow dung with farm yard wastes like leaves & branches of left over vegetable plants & weeds removed. for at least one & half year besides some vermicompost. Growth of fruit & flower plants is very slow.

  3. Please read in continuation with my previous mail enquiring about the fertiliser to use. Our farm is in tropical part of India where mangoes & chickoo ( sapota ) grow well. We have excavated some part of the farm & made water harvesting pond. But made the mistake of over turning the soil and putting it on the top of remaining part of farm. Hence the upper layer of bio rich soil has gone deep down and stones & gravels have come up. So the fertility of soil has gone down. Can you suggest fertiliser to suit the soil for proper growth of plants?

  4. Why can’t I find how to and what type of fertilizer to use on established centipede grass? Everyone dances around my question but they seem to be afraid to answer. I just want information so I can make my own decision!!!

  5. Which r the best fertilizerd used in Button Mushroom Compost?
    For the requirement of phosphorus, potassium and magnesium

  6. IPLANTED HYDRANGES AND RHODENDRONS IN THE SPRING. NEITHER ARE DOING WELL. THE BLOSSOMS ON THE HYDRANGES WERE NON-EXISTANT, SAME FOR THE RHODENDRONS. THE HYDRANGES LOST LEAVES AND LATER HAD SPARSE LEAVE GROWTH. WHAT ADVICE DO YOU HAVE FOR THIS TIME OF YEAR TO IMPROVE THE PLANTS AND HAVE BLOSSOMS NEXT YEAR? THANKS

    • Hi, Walter,
      Gardening questions can be tricky since the rules can change based on the region. You didn’t include the location so we would suggest contacting your local Master Gardeners association.
      Master gardeners train on a range of topics so they can provide advice, at no charge, for people in their area.
      Thanks for your question, and good luck!
