On January 21 we got about 6 inches of snow that took about 5 days to finally melt off. Before that the grass was green and wavy, albeit slightly stressed due to traffic, but that is unavoidable.

Got 0.81" of rain on February 1st, and had temps in the mid 60s. I have noticed a lot more yellowing of the grass now, I think due to the hard freezes we had in late January combined with the snow.

Typical February weather so far. High temps in the mid 70s, lows in the upper 20s. Rain at 4.28".

Grass has been sprouting in spots that went dormant early in the renovation last fall. We have grass in areas that NEVER had grass before (in the areas to the left of the greenhouse).

Expecting 8-13 inches of snow over the next 24 hours, so that sucks. Hoping the grass isn't hit too hard.

February Summary:

Typical NE North Carolina February with temps ranging from 17.9° to 75.5°, with an average temperature of 44°F.

Rain accumulation: 4.63".

Snow accumulation: 11.4" (likely approximately 1" of rain).

I'm due for the following maintenance: Spreading Grubex to help minimize mole population (I've killed 6 in February alone).

Tomorrow (01 March) I'm spraying Barricade 4L at the 4x rate (2 ounces in 4 gallons over 8000 ft²).

Grass is looking really good considering the beating it's had over the last couple weeks (snow, tractor etc).

March Summary:

Temps ranging from 28.8° to 79.8°, with an average temperature of 53°F.

Rain accumulation: 2.77".

Its green. Dry. Poa Annua and Poa Triv are the worst I've seen, and I don't wanna do blanket apps of post-emergents to battle them, so hoping the heat kills it, and then the Pre-M apps will lessen it next season.

Mowing every 4 days, previously at 3ÂĽ inches but it looked thin, so hoping that mowing at 2Âľ will help it fill in.

Planning no irrigation, and will mow it longer during the super hot months, but I may change my mind if I see too much stress.

Will apply meso on 3/30 (first application).

Will apply .2lb/k nitrogen 3/30.

Rain expected 3/31 (15%).

April Summary:

Temps ranging from 36.5 °F to 90.6 °F with an average of 63.9 °F.

Rain accumulation: 2.61 inches.

It's dry. Already in a drought - I had REALLY hoped to not have to irrigate this year, but that isn't going to work. Already had a patch of grass die / go dormant to the left of the greenhouse.

My wife stopped at the state co-op and picked up some soil sample kits, so I'm going to take several cores and send them in for analysis.

I must've hit something with the Timemaster - had a large bang and upon inspection saw the blades had hit each other. After pulling the belt shroud I discovered a thrown synchronous belt and a completely missing idler pulley! Replaced with Exmark parts (hopefully an upgrade).

The POA is kinda sorta dying off. I'm planning on overseeding this fall, so I only have one more app of prodiamine to lay down. I doubt I'll catch the POA seeds with that - Something to deal with next year.

On Friday (5/2) I mowed the yard at 3Âľ". I've been watering again. 0500-0700 with impact sprinklers. The dead patch to the left of the greenhouse is beginning to recover. I wish I had noticed it going so quickly, because there are some pretty beaten areas (just in front of the greenhouse) where the grass was thick and lush - it dies so quickly. It isn't even "hot" yet!

Also, my HVAC went out. So that's 10 grand I wasn't planning on spending. Exactly 1 month after I spent $1700 to have a leak repaired and coolant added. UGH!

On Sunday (5/4) it rained 0.96". I'll start watering again on Wednesday.

May 6th was a beautiful day, so I decided to get in a quick mow. Took the HOC down to 3ÂĽ, figuring that now that I'm watering it, might as well enjoy the shorter look.

The grass revival is happening on the left side of the greenhouse - I was curious if it was dormant or dead, because I've never seen this grass go "dormant" since it was planted. Maybe it did die and the other grass is just spreading? I dunno....

The place smells amazing, all of the privets are in full bloom!

I have a few clover living in the yard. I could spot treat, but I don't see it really hurting anything.

May 12-18 brought 1.2 whole inches of rain, so I was able to turn off the irrigation for a few days, but will resume tomorrow morning.. Mowed twice last week to 2Âľ inches, both time removing way more than a third of the blades. With the majority of rain falling from Wednesday thru Friday, I had roughly 3-4 inches of growth in 4 days.

Ordered T-Nex today (5/19)

I have perfectly round dead spots I attributed to my dogs, which is possible and most likely, but I read on Supa's journal about deer, which I know pass thru the yard. Now, if I can figure a way to get the grass back in those areas. You can see the dead circles from in the pics..

The "dead" area to the left of the greenhouse is recovering. I watered that area VERY heavily. I believe a lot of the dead grass was Poa, and the heat knocked it down.

May Summary:

Temps ranging from 51.3 to 93.8, with an average of 70.5°F.

Precip: 3.35 inches, mostly the last 2 weeks of the month.

The Poa is all dead now, which is positive, the flip side is where the Poa was active, I now have some patchy/thin areas. Shortened my HOC for the last 2 mows to 2.75" to promote tillering, and to help the grass dry out. Started getting mushrooms in the yard, typical of this time of year when it starts to get hot & humid.

Mowed the back at 3ÂĽ" Saturday June 7th, took off maybe Âľ inch in the places the PGR was sprayed. The front was mowed at 1", and took off less than ÂĽ".

Mowed again today after 5+" rain over the last 10ish days and the grass is still on regulation, but just barely. Back yard mowed at 3¾" because the 95°+ days have arrived.

Found a small patch of Virginia buttonweed and hand pulled. Never had it before and surprised it's growing despite two applications of prodiamine, which tells me that pro-d isn't effective against VB, as I suspected.

Considering mixing some of the concentrated weed-b-gone for spot application, because MSM Turf just scares me in this heat! Open to suggestions...

I'll start irrigation again on Monday to maintain 1.5" a week.

6/19-6/20: The "light shower" put down 1½" of rain last night, and I had errands this morning that prevented application of T-Nex.
According to littlleaf.com, I'm at 233 days since application which doesn't come close to Greencasts's calculation of 431 days. Obviously the numbers are calculated differently. Makes it difficult to decide what to do, but I don't want to experience rebound, so I'm going to re-apply this evening at the same rate as last time (1oz/M).

I'm also adding Main Event 6-0-0 dry iron at the 1oz/M rate.

What GDD @ Temp do you have your threshold setup on Greencast? Mine were only off about 1 day between the two tracker.

@supa I can't login to Greencast. I created my account, got my welcome email and the first time I tried to get in it locked me out. No responses from their support team either, so I just use the generic tracker.

For base temp on Greencast I use 0°C, because that's apparently what one should use for cold season grass. I'm not certain what littlleaf uses, as I don't recall an option for base temp, however he stated on this forum that anything with a base of 400 GDD was automatically assumed to be cool season turf.

All that being said, I'm basing my applications on both the cool season and the warm season PGR threads, and it looks like 2 weeks is a happy rotation with my minimal app rates.

I definitely appreciate only mowing once a week, but I can see some minor rebound happening now (I'm at almost 3 weeks due to rain). I'm applying tonight fo shizzle!

My soil reports can't back and just like everyone else's, I need to apply lime. Quite a bit of it, so I took the opportunity to grab this 100lb spreader whole it was on sale. If it falls apart after the lime is put down (around 1300 pounds), at least I won't ruin my "good" spreader.

The price is right on the vevor spreader! Looking forward to hearing how it works for you.
