So I put out my fertilizer and herbicide yesterday evening (my only chance for a while and following Lemmon's guide) and since it had rained 4 inches and I had a fairly wet yard, didn't water it in. Should I water it some today? My yard is about 1.5 acres so I'd rather not waste that stuff and make sure it's applied correctly.

if it rained 4" there is a good chance everything you did was carried away in the rain.

Application was yesterday evening well after the rain was done.

Yes, water it in.

I know you didn't ask, but I've always heard not to apply both at the same time. I have no idea how much it matters.

Per our Aggie Expert, Neil Sperry...

A Note from Neil on Weed and Feed Products

Not from the link you posted, but from Neil Sperry, "Any time you intend to apply pre-emergent weedkillers and fertilizers at roughly the same time, apply the fertilizer first. Water it into the soil deeply. Wait a couple of days, then apply the pre-emergent granules and water lightly."

Way too early in DFW for fertilizer

If you listen to Randy Lemmon I hope you have money to burn. He sells anything and everything that someone will pay him to do or in his case say. If you read the God Father of Gardening for Texas, Neil Sperry. You will see it is too early to fertilize, soil tempt. is too low. Go to his website and save yourself money and time. Here is his article on early spring lawn care. Run as fast as you can from Randy Lemmon advice, he does not even do his own lawn.

Yea, that Lemon guy acts like a horticulturist when he actually was only a communications major!
He has turned into a product salesman.

Its not too early to fertilize. Its routinely in the 70s and 80s in Houston and lawns have been green for a month already. Neil's schedule is for areas a few hours north of us.
