We get this question all the time and there really is no easy answer for it so in this article we are going to break it down and appeal to your sense of logic at the same time.
First off, for most homeowners, there are 2 ways we can apply. One is via hose-end sprayers, such as our quarts or the Ortho Dial N Spray, and the other is via battery sprayer also known as a hand can or backpack sprayer.
Applying with a Hose-End Sprayer
Straight up: if you are applying your N-ext products via a hose-end sprayer, you should NOT mix them together. The 32oz tank on a hose-end sprayer is just too small to make sure they are going to flow properly. If you mix them, you are going to face clogging issues so we recommend you don’t do it.
Spray them one at a time from a hose-end sprayer.
If you are using the Ortho Dial N Sprayer, there are some modifications we recommend that will also help the products flow better. Remember, these products were developed for professionals who use them through much higher quality and larger equipment. It’s awesome that they are available to us homeowners but to get them to flow trouble-free, there are some basic modifications to make to your Ortho that will help. The good news here is the Ortho is only a $10 piece of equipment so cutting off the filter like in this video isn’t really a big deal.
If you are using a quart hose-end sprayer, you will want to measure out the recommended amount of product to cover 2,000 square feet, place that in the empty sprayer bottle, and fill it the rest of the way with water. You can find more information on how to use this here.
Applying With Battery Hand Can or BackPack
If you have a hand can or backpack sprayer, we recommend you get one powered by a battery. This will save you tons of frustration but also make your application more consistent because a battery sprayer delivers constant, consistent pressure resulting in an even application.
Applying from a battery sprayer, either a 2-gallon hand can or a 4-gallon backpack, you can mix products together in the tank with these caveats:
- Be sure to fill the sprayer halfway with water first, then add the concentrates
- Even the best battery sprayer will clog if you get too much concentrate in there so do not mix more than 2 of the products together at any time. Again, just avoid the frustration of potential clogs.
Here is a video showing you how to apply one of our most popular liquid concentrates, 0-0-2 MicroGreene from an Ortho-Dial-N-Spray, and a 2-gallon battery sprayer.
All of that said, let us urge you NOT to mix them together anyway. Spread out the products over the year. That is how they were designed, to be applied over the course of a year, not all at once.
Applying all of them on the same day isn’t going to hurt anything but there is only so much that can be properly absorbed by the soil so if you pack them all in during one miracle application you are just being wasteful.
Here is a basic plan for applying the bio-stimulants from the Bio-Stimulant Pack which is what 80% of our customers are utilizing. You will see, for example, the mid-spring application calls for RGS, Air8, and MicroGreene. That is not telling you to spray them all down in one day. What that is saying is “during the mid-spring, get an application of each of these down during that time period.”
Maybe you apply Air8 this weekend, MicroGreene the next weekend, and then wait 3 weeks and apply the RGS. The idea is to spread them out so that goodness gets spooned in over small doses.
Now if you are pressed for time, you can apply them all on the same day - it will not hurt anything, but again, try not to be wasteful.
The reason we stress this is that all of those products contain humic acid as the carbon source. If you apply them all on the same day, that is a LOT of humic acid going down. Now, don’t let the word “acid” scare you, even if you triple dose ALL of them on the same day you will not hurt anything, but there is only so much benefit you are going to get in one day as the soil can only hold so much so if you over-apply, or bomb them all in on a single day, chances are some of it will just go to waste.
So spread them out over a few weeks and enjoy the spraying and the praying. What you will find is that as you get more results and the lawn looks better and better, you are going to want to apply something every weekend. This program allows you to do that. Spraying a little here, and a little there, spaced out.
