The standard Weed-n-Feed granular product never worked too well for me. This is likely attributable to laziness. I didn’t want to get out early enough in the morning to apply it while the grass was wet! However, another negative was the cost of the name brand Weed-n-feed products. At $50 or more per bag, the cost is comparable to a lawn service.
So, for a few years, I used a name brand lawn service. They did a beautiful job. However, as the years rolled on, I was still bothered by the cost, and the nagging lack of that ‘DIY satisfaction’ feeling. Honestly, if you don’t get a certain level of satisfaction by doing something like this yourself, then I would suggest you continue to use (or start using) a professional lawn service. The can do an incredible job of keeping your lawn green and weed-free for most (hard to handle the hot/dry part of summer) of the year.

Ok, so you STILL want to do it yourself? So do I! Let’s dig in!
Broadleaf Weed Control
First, we need to control dandelions. Yes, my young daughter enjoys dandelions, and is sad when they are killed. However, with some training, she can be convinced about how evil these persistent yellow buggers really are! Dandelions and other broadleaf weeds can be killed with 2,4-D. However, using the agricultural version of 2,4-D can present some issues, as it tends to ‘drift’ when sprayed, and may kill some flowers alongside your yard. Also, you can get better weed control by getting a mixture of 3 or more chemicals. This mixture is often referred to by a brand name ‘Tri-Mec’. I use this (please order through this link to support Tractor Time with Tim):
This should control the broadleaf weeds in your yard. If it does not kill after 3-4 applications, you will probably need to specifically identify the weed causing issues, and ask for help from an expert.
Crabgrass is very difficult to kill once it is growing. Further, it seems to thrive in the late summer heat when the ‘good looking’ grass is really struggling. For whatever reason, crab-grass doesn’t seem to need much water to thrive, and it can expand over large areas of your yard in just a few days.
There are some ‘crab-grass killers’ available, but they are difficult to use. It is easy to damage your lawn with these chemicals. So, the best defense against crab-grass is to keep it from getting started. We can do this with, yes you guessed it, ‘Crab-grass preventer’.
There are several chemicals to prevent crab-grass from emerging. My favorite goes by the brand name ‘Barricade’. Barricade is quite expensive, and there are generic versions available. I use this one:
It is best to ‘premix’ this product in a small container to dissolve the granules, then poor the pre-mix into your sprayer.
I recommend applying this with each time you go over your lawn. The only time to skip this product is if you are trying to get new grass to sprout and grow. This product will prevent any grass from sprouting and growing.
Much could be written about lawn fertilization. I am certainly no expert in this field. However, the basics are relatively simple. You need a fertilizer with high nitrogen content. This is the first digit in the 3 digits you always see on fertilizer. For example, 18-3-6 is 18% nitrogen, 3% Potassium, and 6% Phosphorus.
You can get your fertilizer in liquid form, or in granular form. If you have both types of spreaders, then simply choose the least expensive approach, which is usually granular. If choosing a liquid, it is best to choose a ‘controlled release’ product. Here is an example:
CoRoN from domyownpestcontrol
I chose to use this fertilizer from Rural King last year:
Gordon’s Fertilizer from Rural King
You can also choose a non name-brand granular fertilizer from your local hardware (or big box) store. Just be sure to avoid the combo ‘weed-n-feed’ treatments if you are applying the chemicals separately as I recommend above.
I usually find the lower cost granular fertilizers way at the back of the store in both Menard’s and Lowe’s here. They would much prefer selling the $50 bags than the $10 bags.
I hope this helps you to get started. My main advice when beginning is to use low application rates to start. You can always re-apply it a second or third time if you don’t see the desired results. This is much easier than re-seeding your entire yard due to over-application.
