Like I've said in my other reviews I do my homework before I buy. Here was the one place that I didn't and I screwed up.
The fertilizer is this bag is very good. I love Scotts fertilizers. Never burned a lawn yet. [knocks on wood] That said, the fertilizer could be better. I'm sad to say that this version of the fertilizer lacks some of the micronutrients the Super Turf Builder lines have and if I could steer a future purchaser in that direction, the Super Turf Builder lines are definitely the way to go.
Secondly as a result of this purchase, I'm not a fan of the combination products. The crabgrass preventer, Halts, that is in the product must be applied early before germination of the crabgrass seeds begins (a pre-emergent preventer). In some cases this may be late winter to very early spring. In fact it can be so early that you might be needing to wait to apply your fertilizer for another month or so. Having the two products combined then can create a little issue as you can see.
Then there is the issue of the Halts crabgrass preventer. It prevents germination of crabgrass seeds (which require 3 consecutive days of 56 degree weather to germinate), but it will also prevent the germination of any new grass seed you may want to put down. So if you are the type to over-seed in the spring or fall, then you can't over-seed for 3 - 4 months after application! This is a fact that some people fail to realize and then wonder why their newly laid grass seed isn't germinating. Then if you read the label, it says once laid down to not aerate, rake or disturb the lawn as you will break the protective barrier of the Halts. Hmmm...guess you better start raking and de-thatching REAL early if you plan to use this product correctly.
I didn't quite know all of this at the time of application. I was too busy raking, de-thatching, and aerating since it had warmed up. I then applied this product. Oops. So I got the affect of a beautiful green spring lawn, but some green crabgrass and weeds coming up too as I missed the pre-emergent window, albeit not by much.
So in short, the fertilizer is very good, but not great. The Halts is a great crabgrass preventer, BUT only if timed correctly (as it is not possible to act as a post-emergent treatment), and you don't plan to over-seed, rake or disturb the lawn.
As such, due to the issues of correctly timing crabgrass preventers, combined with the needs of over-seeding and fertilizing at the right time, I just cannot recommend this product.
To correct for the over-seeding concerns, one would want to go with Scotts Starter Fertilizer with Crabgrass Preventer instead. That contains Tupersan, a chemical that selectively inhibits crabgrass germination (and other weeds!) while allowing grass seed to germinate. Nice, stuff, but as you will see, it costs much more $$.
If you do go the separate and not combination product route, and you are looking for a product that prevents crabgrass in a pre-emergent AND early post-emergent manner (just in case you are just a little late with your application), while still catching and preventing more of the common weeds too, well, you will have to look outside of Scotts.
