Fertilizers come in two forms, granular or liquid. Liquid fertilizers are easy to administer to large areas, such as a lawn. They also can be made in smaller portions for use in flower pots. A garden sprayer allows you to cover a large area, while a watering can will apply the fertilizer to smaller areas. If you make liquid fertilizer at home, you can be confident it has no unwanted chemicals in it.
