Fertilizers: Granular or Spray?

There are two main types of fertilizers available for your lawn: granular and spray. While both will help make your lawn green and keep it healthy, they are vastly different.

These differences begin with the cosmetic features of each type of fertilizer. Granular fertilizer is just what it sounds like — it consists of little, solid granules that must be spread over your lawn evenly. Spray fertilizer is a liquid that must, obviously, like its name, be sprayed evenly over your lawn. Both types of fertilizer can be picked up by your lawn mower after application, since the majority of liquid fertilizer remains on the blades of grass themselves, and the granular can sometimes be “sucked up” by the lawn mower on each pass.

In terms of overall environmental harm, liquid fertilizers can do more damage. Not all of the fertilizer will soak into the soil, and what remains is easily susceptible to puddling on top of the soil and will get washed away either when you water your lawn or  during the next rainfall. Because of this, granular fertilizer comes out on top when considering the environmental impact.

Liquid fertilizers also need to be applied more often, because of the reasons listed above. When granular fertilizer is applied correctly, it will last for the lifespan of each granule. Depending on which type of fertilizer you have purchased, this means that you could go up to 3 to 6 months (with the slow release kind) before you have to reapply it. This beats a liquid fertilizer, which will have to be reapplied at least once a month.

Another factor to consider, involves the overall application and preparation of each. Liquid fertilizer is messy and has to be mixed before application, whereas granular fertilizer only needs to be poured from the bag into the application device. This makes it much easier to use.

When you consider all of these factors, granular fertilizer easily comes out on top.
