AZ TifGrand 2020 Journal

Post by AZChemist »

Welp, it’s about that time of year where the lawn will begin to transition from PRG to Tifgrand. The sod laid in October has barely rooted into the sand base below. That means once it heats up the Tifgrand is going to stress. To help the newly established yard settle in I picked up and will be adding RGS to the 3-4 week interval sprayings of PGR.

My initial reaction was that RGS smells like sewer gas and that I can’t spray this stuff wearing sandals. Am curious to see the improvement over the 5 gals I’ve purchased.

The lawn is still kept relatively low. 0.6” on the 2653 and 0.45” on the toro flex. Perhaps mid Feb the lawn will be scalped and verticut. This is where the Timemaster shines. While it unfortunately does not mow low, the sucking power is fantastic. Even if it’s just for some leaves.

Not sure if it’s the heat, the iron in the RGS, or a placebo effect, but 1 week after an app of RGS the lawn has taken a deeper shade that resembles an app of FAS.
This weekend the lawn will get a cocktail of PGR, Bifen, some more RGS, and Prodiamine. I want to be ahead of the crab grass this year so I plan on doing quarterly apps of a pre-emergment.

Bermuda is slowly coming awake.
This weekend I got down some pre—em for my spring app, rgs, and pgr. Hoping I can find some time to verticut and scalp in the next few weeks. The sooner the bermuda comes the sooner I can throw sand on it.

A week ago the lawn saw its first nitrogen feeding since October. The 21-0-0 followed by a weeks worth of rain made it all pop fast.

The light areas that were stressed from 80 degree weather have began to darken up as the bermuda is making it’s appearance.
Everything is easy stressed due to sand below and the lack of supporting root growth. To date 5 months later I can still pick up the sod like pieces of carpet. Hard to keep things watered when your root zone is only 0.5”

The old part of the lawn has a ton of ring spots. But not with dead grass. Since the N was put down the light areas filled in with a dark center in a circular fashion.
Not sure if it’s just how the granulars were thrown out, or a fungi.
I don’t have a fungicide in my schedule but to be safe I’ll spray some propiconazole or azoxy.

Spraying PGR, Quinclorac, and RGS today.
Prodiamine is doing a great job and only really have a weed or 2 in the lawn.

More rain is coming. Should I have some time off at home, putting the catches on the 2653 will be bumped up on the to do list.

Actually trimmed and edged this weekend which I generally don’t do.
Bermuda is sllloooowwwly waking up and the non established lawn won’t stay wet. If I learned anything from this project it is that sod in Arizona is best placed in spring. Not summer or winter as I have done.

Just ordered 10 tons of top dressing and will be here by weekend end. Never been so excited for manual labor!

Finalizing that transition into summer. High 80s all week. Once the temps hit 80 it never turns back till November.

2 passes with the verticutter followed up with rotary to clean and then scalp to 0.4” where I’ll leave it all season long.

Yes it is! Even keeping the lawn short the grass has a tendency to get spongy due to the lateral growth. All of this is from Oct-now. I took it down to dirt when the rye was over seeded.

Thanks for the kind words as well.

One more for today. I made it to 0.4” double cut. Been a minute since I’ve used the toro flex and it was walking all over the place.

15 tons of USGA spec top dressing.
Way more than I need for the lawn, but also have a travertine paver pool deck project that it can used for.

Phase 2 of verticutting complete. Today consumed more than 2 96 gal trash bins. All in all for 6ksqft over 400 gallons of debris was removed. The new sod area benefited from it the most. The sod farm clearly let things get long. This left me with shoots that were as thick as twigs. Since this is this first time I am seeing the bermuda there was a reservation inside of me to if they even sent me the right cultivar.

The verticut removed most of puffiness and annual rye grass that remains and looks a little more like the established side.

I’m going to switch cutting heads on the toro to the groomer and lower things down to 0.35”. The groomer goes a good job and pulling up the last of the rye.

Tifgrand low and trained is phenomenal, let it get puffy and tall and It’s nothing to rave about. I want to keep things low low until I can level it out.

Tonight I’ll get some rgs and PGR on it.

Maybe it’s because one side has almost a year or PGR. Maybe it’s cause the other side has no roots, but as of now I’m still leaning these 2 are not the same cultivar. 🤷‍♂️ Hard to make out but the shoots and leaf size are so much larger. I want my dwarf tiff!
