bernstem 2021 lawn journal

Previous journal: viewtopic.php?t=16804

The season is pretty much open in St. Louis. This weekend was winter cleanup. Leaves blown out of the gardens, roses pruned back and winterizer removed, lawn mowed with the Honda and garden debris mulched into the turf, and gardens mulched. It is starting to look like a lawn again.

I'll keep the low cut going as long as possible, though I haven't broken out the Swardman yet. The real question is whether to renovate the front to a monostand of After Midnight. NTEP umbers look very good in the transition zone and I have a source for seed. Other than that the recurrent Summer Patch will likely be the biggest challenge. I'm interested to see how keeping it cut low impact disease.

No garden photos yet, but most of the roses seem to have wintered well. I lost two that I know of, and have two that are unhappy but should pull through. The biggest issue this spring will be protecting them from pesky wabbits.

Anything in particular that you've tried that works well? I've tried the deer and rabbit repellent spray, hair, urine, milorganite, a few others that skip my mind and haven't had overwhelming success. Even my dogs (both in double digit ages) have lost the edge in keeping them away.

The only thing I have found that works well is a physical barrier. I currently use bird netting as a physical fence reinforced with copious amounts of rabbit repellent.

Lawn is starting to wake up. Got in a real mow (3/4 inch), though there is still some winter damage yellowing the lawn. Also scarified before mowing. Front and back this year seem to be waking up at close to the same time. In the past, the back lawn was ~1 weeks ahead.

The gardens are starting to wake up. The roses are sending out new shoots, the Daffodils are blooming, Irises and Lilies are growing. Tomorrow will be the first rose fertilization of the season. I put up rabbit netting last week to protect the new rose shoots.

A quick update. Applied AS at .15 and Primo at 0.2. Roses each got 1 cup (climbing roses got 2 cups) of Mill's Mix. GDD tracker and Forsythia say to apply pre-emergent now. I usually use Prodiamine at the 9 month rate or spring/fall apps at half that, but I have some free granular Dimension sitting in the garage that I'll try this year on the back next weekend. The front is going to go without pre for a possible fall renovation.

Subscribing to this journal for sure!

@bernstem thank you for all the advice last year. Really helped me along through my reno last year.

I see through other threads you are an AMS guy. How early you get it sprayed, and at what rates?

@Slingblade_847 Early spring Nitrogen varies depending on what the lawn seems to need. This year, it appears to be waking up from winter better than in the past so my plan is low dose foliar Nitrogen (0.15-0.25 every 2 weeks or so) with AS based on growth rates. I use the AS as my pH is high. I'll probably apply a granular with Potassium later in the spring at the more traditional spring fertilization time, but it is still too early for a big dose of Nitrogen. I generally like to match Nitrogen to growth, so will apply in the spring, slow down in summer, and apply the most in the fall.

I am also starting Primo applications earlier this year as well. The idea behind that is to prevent as much shoot growth and try to push root growth and density.

Lastly, I'll be on a preventive fungicide regimen for Dollar Spot and Summer Patch. I am hoping to keep the rates lower this year than in the past. I expect the quicker AM drying from low mowing and work to reduce pH should reduce disease pressure.

@bernstem thanks, buddy. Insightful. I do have some more questions on the AS, but I’ll tag you in my journal vs. sabotaging yours. Your Lawn lookin good so early in the season!

What are you using as a preventative for your Summer Patch? I've being using Companion the last couple of years, but have not been able to source any this season... Between that and rabbits, we seem to have many of the same issues :(

One got propi 14.3. from DoMyOwn last year. Just checked the product label and includes summer patch. According to their website it’s available,

https://www.domyown.com/propiconazole-1 ... YREALw_wcB

Here is their recommendation for summer patch

@HoosierDaddy I use Azoxystrobin for Summer Patch. My rotation the past couple years has been Propiconazole and Azoxystrobin in the spring transitioning to Velista and Azoxystrobin in the summer. I have never been able to adequately control disease here in St. Louis with just biologicals and cultural practices.

@bernstem I apply a round of azoxystrobin in the Spring when soil temps hit 65 for 4 days. Then apply again at onset of symptoms. I've also been applying Companion around the same time and continuing through Spring. I've not tried Propiconazole. I've noticed improvement over the last few years, but still have pretty bad outbreaks. I'm not sure what to change up so I was hoping you'd found a magic bullet.

@HoosierDaddy I wish I had a guaranteed solution to Summer Patch, but... I don't.

I think you need a minimum of 2 applications of Azoxystrobin. The first when soil temps hit 65, and again a month later. That is a minimum for Summer Patch. I generally try to keep protection down from 65 degrees until fall. I'll increase dose/frequency of applications if I see disease breaking through. I'm hopeful this year that some of the pH reduction and faster drying with lower cut turf will help, though the low cut might just increase stress instead.

The lawn is finally awake despite last night's 28 degree low. Tomorrow will be pre-emergent. Today was getting the lawn fully cleaned up for spring. Walkways got edged. The garden was edged and then deepened with a bed re-definer. The front and back got scarified to clear out lawn debris then double cut at 5/8. There is still some winter damage that needs to grow out, but it is getting better. The dark green canine spots are fading as the rest of the lawn greens up. Gardens are awake, but nothing except daffodils and early Forsythia blooming.

Front is looking good. Makes me question moving to a monostand.

Thanks! Spring is always easy to get it looking good. Keeping it looking good into late summer is the challenge.

At what temperature do you start your AS, and at what rate?

@Slingblade_847 I struggle with when to start fert. I don't see much dormancy, so have been working on how to manage winter Nitrogen which affects spring Nitrogen. Late last fall, I applied stabilized Nitrogen which seems to have carried the lawn through winter and allowed it to come into spring in a good position. I don't have a detailed plan, but instead try to judge what the lawn needs on a week to week basis. This year, I am roughly planning to foliar feed light doses of Nitrogen based on growth. To that end, I applied 0.15 lb/M a week ago concurrent with Primo growth regulator at a low dose. I'll probably repeat the AS in a week.

@bernstem Great pics!

Thanks for the s.p. tips. I will try the double Azoxystrobin this Spring. Proactive Serenade apps have reduced all other fungal issues for me to essentially zero, so I was hoping for something similar for s.p. I am still trying to see if I can source some Companion so that I can use it as well. I did read a study (Rutgers?) once upon a time that azoxy plus Companion was the best treatment, but I can't seem to find it again for details. Thanks!
