Using the Scotts multi step program is about as far from "natural" as
possible. * *What they propose is constantly treating your lawn with
chemicals, whether you have a specific problem requiring them or not.

Given that you think the Scotts weed n feed killed your lawn over
night, the first thing I would do is call Scotts. * Getting opinions
from the store or a neighbor is worthless. * *The neighbor spoting off
about the clover is clueless. * There is no way the clover nitrogen
cycle has anything to do with your problem. * Also, you put down a
slow release nitrogen, not Amonium Nitrate. * *Also, putting down
hebicide when it's in the 80's is not a good idea, as it can indeed
damage the grass. * But if you applied it anywhere near the correct
rate, there is no way it would turn the whole lawn yellow over
night. * For that to happen suggests something was wrong with that
bag.

I'd keep the lawn well watered and see what happens. * Just because
it's yellow doesn;t mean it's dead. * It's possible it may come back,
however the fact that whatever happened occured so quickly suggests it
may indeed be kaput.

If you want to start reducing the chemicals you are using, start by
not using weed n feed. * With a 2 gal tank sprayer, you can apply a
minimal amount of herbicide directly to the weeds. * This does 2
things. * It minimizes the amount used and it delivers whatever is
used directly to the weeds instead of broadcasting it everywhere.

I also would not be putting down nitrogen hot weather either, as it
promotes fungus and disease. * The best times to fertilize are Spring
and Fall.

Finally, if clover is your main concern, I doubt a weed n feed product
is going to do much, if anything to eliminate it. * Clover is much
tougher to kill than broadleaf weeds. * Look in the lawn/garden center
for products labeled for clover and apply it with a sprayer. * *That
is assuming you have so much that you want to get rid of it. * The
"natural" folks acually prefer clover.

Michelle - So far you've gotten a lot of bad information, mixed with a
little decent advice.

The fertilizer part of the Scott's weed control program is a 28-2-4, which
means several things --
* * a. *It's got a LOT of nitrogen in it, and probably a lot of that is
ammonium nitrate, just as you said. *Trader is wrong in his comments about
slow release

Scotts product most definitely does contains a large portion of slow
release fertilizer. Your misleading statement would lead the poster
to believe that it is ALL quick release, which it is NOT. And it is
NOT comparable to straight ammonium nitrate, which is indeed all quick
release, which is why I offered it as a comparison. Scotts is a
combination of quick release and slow release. If you put down 28%
ammonium nitrate, all that nitrogen is quick release. In the Scotts
product, a significant portion of it is slow release, so you don't get
anywhere near 28% nitrogen release immediately. Most importantly
the nitrogen will not burn the lawn and cause it to go yellow
overnight when put down at the correct rate. Which was the point, was
it not?



to be effective, a lot of the fertilizer in a weed-and-feed
is water soluble to provide near-instant greening that will mask the
herbicide effects of the product.. *There's probably a lot of ammonium
nitrate that you spread, but Scotts website does not list the specific %s of
ammonium nitrate and other nitrogen sources, probably intentionally.
* * b. *He's right, however, that the ammonium nitrate shouldn't have made
your lawn yellow (unless it was really overdone in very hot weather)-- but
the herbicide in the product might. *This effect is magnified if you used a
product intended for cool weather lawns on a warm-weather grass such as St.
