New Tall Fescue lawn yellow spots

330 Views 12 Replies 9 Participants Last post by  davems
Hello,

I've just seeded a new construction lawn with titan rx tall fescue in March, I'm in zone 7b and was wondering if anyone has suggestions on the yellow or light areas. I plan to level out some areas, aerate and re-seed in fall, but not sure if I should bother doing anything now? Thank you!

Haha, OK yeah I'll bag up the junk. I used a starter fertilizer when seeding and again about 3 weeks ago... hit it again?
Looks like misapplication of fertilizer. You or whomever applied the fertilizer needs to learn how to do it properly. The yellow areas are the missed areas of fertilizer. Most likely a drop spreader was used. Rotary spreaders are preferred.

Agreed, looks like a rough fertilizer job
I used a rotary spreader, but I actually noticed it wasn't spreading very even, will get a better one and reapply fertilizer. Thanks for the feedback!

If you have an edge guard make sure that it doesn't fall down or close as you go.

But make sure you get it water if it starts getting hot. A high nitrogen number will burn the new grass blades without adequate water. With water it will green up like those stripes.
get some milorganite or order purely organic lawn food from home depot is pretty cheap all veg/grain-based and like $20 free delivery treats 5k sq ft the liquid one but the hose bottle it comes in never fully empties so either use the granular or an aftermarket hose sprayer. This way with the organic you can't burn it by over feeding, but I'd still do a small app of urea-based starter to get it fed before it might start getting hear stressed.

Titan RX is half decent I used like 500 pounds of it one year but there's better cultivars that rank higher in NTEP from unitedseeds is a great site and not much more price than titan per pound, mostly all blue label certified high ranked cultivars similar to what seed super store carries but sss is pricey but everything they carry is basically top ranked. Even w shipping unitedseed prices are around what uncoated seed costs in store and is better ranked.

I would keep the straw there to hold moisture and it'll decompose and cause no problem, then maybe in Sept/Oct do a follow up and it'll be denser turf if necessary.

I'll just throw this out there. Do you have a soil moisture meter? Probe / Check the Darker areas vs the "yellowish" areas.
I have regions (not in the pattern your showing) where it's the same darn thing and it's soil compaction (water and fert not penetrating evenly)
Usually this is seen where the pipe was buried / placed (that soil almost 100% of the time has the darkest grass).
Odd pattern to be that though.
But might as well check all the avenues.
I hadn't really thought of that, but actually this is over the septic drain field and the lines of dark are in the direction of the infilitrator channels.

I'll do what @roody2333 mentioned - Thank you, hit with an organic spray fertilizer, then in the fall will aerate and reseed with a better seed. I figure it'll take a few years to dial things in, which is fine, but just seemed like a weird pattern on the grass. Appreciate all the responses and suggestions.
