It stores nutrients the plant needs to grow. When planning your fert schedule for the year you should think of your soil like a bank account.

To overly summarize what these nutrients do I’ll say that Nitrogen is for leaf growth or top growth, phosphorus is for root development, and Potassium is for the grasses immune system, it’s overall health and vigor.Įxcess Nitrogen can become a groundwater contaminant as can excess Phosphorus while excess Potassium doesn’t pose that risk if over applied. Today I want to talk about only one distinct aspect of the lawn this year – I want to talk about the ratio of N-P-K that I plan on applying to the lawn and how much of each macronutrient my grass type is going to be fed.įor people new to the lawn game NPK is the amount of Nitrogen, Phosphorus, and Potassium found in a bag of lawn food or fertilizer. This year I’m going to be trying my best to use as many organic products as possible in my lawn but I also want to continue my work on building up the soil health and inch my soil’s pH lower over the course of the season which is going to force me to do a few things to the lawn that I wouldn’t do otherwise. I like to plan the whole year out as best as I can so that I can pick up the products I need and schedule my applications around holidays, vacations, and irrigation.

As we get closer to lawn season this is the time that I put a lot of thought into the feeding schedule I think I want to follow for the year.
