Get Twenty Mule Team laundry soap (for Boron) from the grocery store, and Zinc Sulfate from EBAY/Amazon. Apply at 3 tablespoons/K each as outlined in the Micronutrient Application Guide, every 60 days.

You just know patches of weeds like-dark green kentucky bluegrass, will break out on that quackgrass monostand!

Wally, at least we know what kills the dreaded "KBG Weed" - determined, loving, expensive care. It always works.

My summer fertilizer of choice is water. Hopefully in the form of rain, but I'll use the synthetic city version if I need to.

You can also apply 0-0-0 fertilizer in whatever quantity you desire, whenever you desire. Make sure to also apply it with Dihydrogen Monoxide.

15-15-15 is available locally and is what I plan to use. About 6.5 lbs/K is the right application rate. Half that for July. Apply monthly. The temperature here has approached the mid 90's, can I do any damage by top dressing in this heat or is it best to wait until the weather cools? What are you t...

There is no waiting line at this time, and we are current on Soil Test Interpretations.

Doc: Very thorough profile of your scenario - thanks!! While a first soil test outlining the differences in soils front-to-back can point out issues, your's doesn't show many differences and I think a single (mixed) test in the future is good enough. Structurally, you've got a Loam soil there with a...

Yes, the book is the one you referenced. And Yes, Humates are excellent at keeping the Iron available for the lawn - it's on my list of things-to-do to come up with a way to build the chelation that occurs into a regimen, but the current list of experiments is as much as I can pay attention to. That...

Mushrooms are not a sign of issues - as a matter of fact they are an indicator of the presence of organic matter. For the most part, they are the equivalent of flowers for mostly-beneficial fungi.

Richard: Given that the size of the backyard isn't that large, you can be rather intense in your regimen without building up large costs or work efforts. Structurally, the lawn soil is a Loam at the high end of 8 - 15 TEC range for loams. That is not a problem as the soil should hold nutrients well....

JVQ: I would contact SEEDLAND.COM. They carry large quantities of forage and pastureland grasses, although I didn't see Quackgrass on the list. They did have a hybrid that was a cross of Quackgrass and something else. They did have a large group of choices though, so I suspect your inquiry will be a...

Very, very impressive - but I've gotten used to that from you, NC !!

I've been hit by thunderstorm after thunderstorm - I lost count after a dozen in 3.5 days

I've never seen any issues with overapplication.

Use products containing fair amounts of Quinclorac, or get straight Quinclorac and MSO (Methylated Seed Oil). Apply as the label directs.

Quinclorac is one of the safest products for newly-seeded/young lawns.

Compare what you see to images on Google of Pythium Blight.

If it is a match, get a bag of Scott's Disease-Ex and get on it ASAP. Pythium tends to spread along the lines that water flows - and will recur when it is hot and humid. Stay on it.

Hmmmm - that's a typical Plano-area soil, but it has a couple of very strange little twists - I don't see one like this very often... The area is very prone to calcareous soils, and you have one. I can spot it and its tricks even through the AA test. You have a boatload of Calcium, and you're pretty...

Difference between the phosphates? Leaning towards the 18-18-18 or 13-13-13, the Lesco with poly is not really selling it for me.. OK - so pick the 13-13-13 or 18-18-18 and tell me which to calculate rates for. Possible to go organic? Considering a dog that likes to eat anything and everything as w...

If you want the Soil Test interpreted, please put a Link into the Soil Test Interpretation Queue.

I don't know all of the acronyms you're planning to use, but I really only see one thing that I think you need to adjust for...

Once the Seed Down time occurs, times are based on "G" (germination), not "T" (Seed Down). And there is a time gap of roughly 14-21 days between T and "G".

For Milo, mid-summer? I think bag-rate is like 14.4 lbs/K, so half-rate would be just over 7 lbs/K.
