Fertilizer

All of our fertilizers are concentrated liquid fertilizers designed to use with our system. For most average size yards (about 2,000 square feet), you will need 1 bag of Lawn Fertilizer and a 1/2 bag of Plant and Shrub Fertilizer for the entire season. That means you will only add this one time and you are done. The FertiWiser System will fertilize your lawn, plants, and shrubs automatically every time your sprinkler waters your lawn.

The available fertilizers are:

• Lawn Fertilizer | 15L bag | 17-0-5 mixture

• Plant and Shrub Fertilizer | 10L bag | 8-16-4 mixture

• Professional Fertilizer | 15 Liter Bag | 32-0-0 mixture

Note that multiple bags of fertilizer can be connected together at the beginning of the season to cover larger areas without replacing bags throughout the year. Advanced users and professionals may also choose to use the Professional Fertilizer for one injector and the Plant & Shrub Fertilizer for the other injector and inject them at the same time to create a Lawn Fertilizer which will double the lawn coverage.
