Lawn Fertility and Timing of Applications

Aug 27th, 2024

We get a lot of calls here at JB Instant Lawn with questions about lawn fertility and timing of applications- so I have posted some current and helpful information below.

Proper fertilization is an important part of managing your lawns health and appearance - and understanding the product and timing of these applications is critical to results.

First things first- all Fertilizers are not created equal. So lets start by looking at those three numbers that always seem to be front and center on most Fertilizer bags. Those numbers let you know the percentage of three important elements within the Fertilizer blend = Nitrogen, Phosphorus and Potassium (N,P,K). Existing lawns- in general will require a fertilizer with higher Nitrogen. 

Now that we know we are looking to a higher Nitrogen content for best results- the fertilizer with the analysis of 25-0-10 like the JB Signature Maintenance Fertilizer or something similar is looking pretty good and is indeed a great product analysis. Applied at (1#N/1000 sf) one pound of actual Nitrogen per 1000 square feet of lawn this may prove to be just right for many established lawn areas and in addition to having a desirable analysis- this fertilizer also has something else we should be looking for in our complete lawn fertilizer- *Slow Release Nitrogen.

Slow Release Nitrogen can be now be found in many of today's blended fertilizers and helps to insure better residual feeding of the lawn over time and also significantly reduces the potential burning of lawn surfaces that some other more immediate release products. 

Timing of these Complete Fertilizer applications can make all the difference in the success and failure in meeting your expectations. While each lawn is different and has it's own set of requirements- some sort of program to insure consistency is important. Below is a simple Fertilizer schedule that can be used as a convenient starting point- *this should not be considered every lawns perfect schedule- and in most cases will require some adjustment over time... 

The Holiday Fertilizer Schedule (1#N/1000 sf for Signature Perennial Ryegrass or slightly reduced Nitrogen for Kevlar Turf Type Tall Fescue).

*JB Signature Perennial Ryegrass Schedule

• Easter
• Memorial Day 
• 4th of July
• Labor Day
• Thanksgiving

*JB Kevlar Tall Fescue Schedule

• Easter
• Labor Day
• Thanksgiving

So lets recap-

1. In most situations Complete Fertilizers with higher Nitrogen content should be used. *(Additional Iron of 2-5% may also be desirable for color enhancement).

2. Some percentage of Nitrogen in the analysis should be Slow Release Nitrogen for residual feeding.

3. Having a Fertilizer Program in place- such as the Holiday Fertilizer Schedule or adapted version- will help insure consistent results in lawn health and appearance.
