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.
