Both liquid and granular fertilizers can work well in this application. The decision boils down to your lawn’s needs, the equipment you have on hand, and your preference. For instance, if your lawn needs nutrients instantly, a liquid fertilizer works faster than granular. If you’re keen on getting consistent results, liquid fertilizers are also the best option. This is because the nutrient composition is the same in each drop of the fertilizer. I also recommend using a liquid fertilizer if you don’t own (and aren’t planning to buy a fertilizer spreader). The liquid lawn starter option from Sunday listed on this page comes with a hose-end sprayer attachment that allows you to fertilize your newly seeded lawn easily with the garden hose you probably already own. If you don’t own a lawn spreader, go this route because while it’s find to spread seed by hand, you probably won’t want to spread fertilizer by hand. With all of that said, there are instances where granular fertilizers are preferred. For example, if you’re fertilizing a large lawn area, or you already own or want to buy a quality spreader, a granular product is the best choice because it can be applied more easily and you’ll probably get better coverage. Similarly, granular starter fertilizers have a longer shelf life than their liquid counterparts. And they feed your lawn for a longer period.
