Ok, fess up. Just how much do you know about lawn fertilizer? Do you shovel out sod food every spring and quickly move to mowing? Do you choose your turf chow based on ingredients, or based on convenience? In the North Georgia heat, packing your lawn with nutrients is nearly as important as good irrigation and watering. And with any lawn care maintenance, development and nourishment shouldn’t stop when the turf leaves the farm.
When to Fertilize
As you might expect, newly laid sod requires hearty nutrition to grow lush and robust. For a full, durable landscape, fertilize your sod two weeks after installation. For an established lawn, fertilize just after spring greening and just before fall cooling. Proper fertilization encourages root growth more than blade growth, so apply your grass nutrition at the right time and in the recommended quantities. It is better to err on the side of under-fertilization than over-fertilization.
Choosing a Fertilizer
With so many types of fertilizer at your local gardening supply store, choosing your sod fodder based on ingredients alone can be daunting. Nitrogen, phosphorus, and potassium are the key macronutrients required to properly fertilize your yard. The three numbers on your bag of fertilizer are ratios of these nutrients. Choosing the wrong fertilizer or using too much of it can encourage weed growth, so make sure you research your grass or ask an expert which fertilizer to buy. Slow-release, organic fertilizers are the safest and healthiest choice for your sod, and can feed your lawn for up to 10 weeks. For easy, organic recycling, leave your grass clippings after you mow: the cut blades release nitrogen into your yard, reducing your need for fertilizer.
