Where are you located? If you have a cool season grass, you don't want to
give it ANY nitrogen during the hot summer months. You only want to give
nitrogen to a cool season grass in the spring and fall. If you want your
lawn greener during the hot summer months, then use a fertilizer with little
or no nitrogen that has Fe (iron) in it. Lesco sells a nice one, or you
could just use plain ironite.
giving nitrogen to a cool season grass in the summer heat when the grass in
going dormant will only stress the grass more.
Also, you ALWAYS want to use a slow-release fertilizer, they are much less
likely to burn your lawn.
good luck,

Hi, I know this question has been asked 100 times, because I did a
google search, but I wanted to ask my question anyway in case some of
the circumstances were different. Here are the details.. its approx
a year old sod.. I laid the second application of fertilizer for the
year on Sunday night. It was pretty hot out, still in the 70's when I
did it. The first application early in the spring, I used some
really nice stuff from a local garden shop. This time, I used the
hardware store special 5000 sq ft for $5 a bag stuff. It was
something around 30-0-10. I used my broadcast spreader and applied a
little less then recommended. I have in-ground sprinklers, and they
go off every morning at 5am to give a light water, then a good soaking
once a week on Wed evenings. Anyway, the sprinklers didn't go off
the next morning for whatever reason, and I noticed the lawn was
turning a little brown in some areas. OK -- I manually turned on the
sprinklers and let it get a good soaking.. Woke up this morning (two
days later) and there are nice and brown patches everywhere.. UGHH.
The blades themselves are green on the bottom near the roots.. but 75%
of the blade is brown from that point up. Any chance this is going
to be recoverable? I am giving the lawn a good soaking twice a day
today.. unless I hear differently, I will continue to do this for a
week or so unless I don't see any improvement, in which case I'll
stop.

My questions a

1. What did I do wrong? I think the mixture of using a cheap-o fert
was mistake number 1. Mistake number two was probably applying it in
the middle of the summer during the day heat. I've used dry
fertilizers in the past with this lawn and others, and never had a bad
experience (except when I dropped a pile of it on a spot once).

2. Will the lawn come back based on what I described? I know its
impossible to tell from description alone, but I really hope someone
can lend some expertise in this!

Things I learned (so far):

1. Quit obsessing over the lawn so much... it really didnt appear to
NEED any fert.

2. If I do fertilize again, use either organic or liquid.

thanks for any insight, I'm really upset with myself right now!!
