Lawn Problem

[clayslandscape]

I have a customer that I have been treating his lawn for 2 years now. That includes aeration, seed, lime, fertilizer, weed killer and so on....

The entire yard looks great except for this one spot that is not that big but its a big deal to the customer... The soil test simply says it is registered at 5.7 on the pH scale and thats all that deficient...

I have aerated before and then topdressed with peat moss but that did not help any either...

It looks like artificially high ground that rises up to meet the base of the tree... try tilling it up with an extraordinarily large amount of compost and try it again... could be tree roots, sand, shade, compaction, or something else...

Not to mention, when they built the house, they had the entire area laid in sod and then had it redone a year later.

What kind of tree is that in the background. Many times trees - certain types of fruit trees can have an adverse affect on turf surrounding them or within the drip line of the tree.

The area is covered in oaks.

I saw acorns in the first picture and then what appears to be sand or agri. lime on other areas. What is that white stuff???
Looks like slime from total over watering!! I know the Melich 3 soil tests will not tell you of impending disease unless you acknowledge to the State that you want a toxicology report. This will probably cost you and the customer needs to know up front. Find out how much first. Under those trees will have grub issues, possible armyworm issues....and I noticed a pine tree.......sap problems because of insect attacks.
It is hard to tell from pics and more in depth studies needs to be done first. I mean, disease or fungus has to be detected with microscopes and involved tests.

What grass type is this??

Probably lack of water due to that serious incline the lawn is planted on. It just runs off!

Lack of water in the woods maybe as it appears to have been cleaned out. All pertinent leaf litter removed. All water drains down the hill..........yes, and ends up next to the house! The turf is green! Unless the soil is tested to make sure and a divider or retainer enclosure is made at the drip line of those trees, then this hillside will not improve.
I can guarantee that the tree roots were severed at the time of construction, so there is nothing but roots down on that slope. Aerating is impossible!!!at first glance. You may only get down 2 inches at best. Build a divider.........add more soil, resod that hill. Plant some native plants to slow down or divert water. Anything to reduce soil and silt loss on that slope will improve turfgrass growth.

He waters with his irrigation twice a day.

Slime mold!
Nutrient loss....silt loss and compacted region on that hill. Grass will grow down hill better than growing uphill. Gravity 101!!!
Still build a divider separating that woodline and start over with new topsoil and sod!
