The NPK numbers are by weight so fillers or not it really doesn't matter. Scotts' 10-10-10 is still going to have the same "potency" as any other 10-10-10.

Scotts' 10-10-10 is still going to have the same "potency" as any other 10-10-10.Scott's claims they use no fillers (inert ingredients) in their fertilizer, and that other brands contain up to 40% fillers. I don't know if that's completely true but as I stated before, it just works better. :dunno:
The reason for a spring feeding is to thicken up the turf before the weeds start sprouting. I'm sure you've noticed that weeds always fill up any bare spots in your yard, but more generally the best defense against weeds is a healthy turf.On the subject of yard fertilizing, I've read and it makes sense, that fertilizing in the spring with a high nitrogen fertilizer is a waste of money. All it does is make the grass grow fast and create more mowing.
