Figured I've asked a few questions here and there and it's time for a journal. I will copy lawn history from previous thread into here when I am on computer later this weekend, but I have one question I want to confirm before I start spraying tomorrow...

Can I seed a weak section of the lawn, and fill in some bare spots 1-2 weeks after blanket app of tenacity? I plan to use the 2 oz/ acre rate tomorrow but will not have time to prepare and seed the area where the dog uses or a few other bare spots. Can I do those next weekend or do you have to seed at the same time as spraying tenacity?

**Full history of lawn

Hello all. First post, been reading around a bit and loving the information. I'm a first time homeowner, and lawncare is in my blood as my grandfather was the first to start hydroseeding in the state of Virginia... he got the contracts for seeding interstate 81 and 64 as they were being finished. Dad is in the geotextile industry, and uncle still runs the company grandad started.

Anyways, enough of that. I purchased my home in Feb of 2016 and had no idea what the lawn would look like when it woke up - well it looked horrible. Bare spots, trees too low/thick, odd green patches from apparent nitrogen spray (literally a ring of bright green in the back yard)tough soil, no earthworms, and tons of weeds. I started with Scotts, not knowing any better and at least woke up the turf. First summer was spent killing the weeds, preparing mulch beds, etc. Fall 2016 after a dry September, we dethatched, aerated, and over-seeded with Jonathan Green Black Beauty Ultra. Fertilized with milorganite, and had good results, most all the bare spots filled in, got a stand of grass under the thick tree, and was pretty happy.

Spring 2017 lawn came out roaring, I think I put down 2 bag rate apps of milo after the first freeze (not knowing it needed heat to be metabolized by the soil). Once it warmed up they started chewing it up and grass was happy, I was mowing every 3 days for almost 2 months. I put down dimension, and spot sprayed weeds as they came up. Put down milo on Memorial Day, July 4, and then Labor Day again did aeration and overseed. Used the same seed, but this time used Dr. Earth Super Natural Lawn Food (Organic) and then we had a dry spell but it was hot and humid. Fungus took in hard, and lawn was hurt. I don't think much of the overseed germinated, so wasted that one. I don't have irrigation and 15,000 sqft is too much for me to water at this time. Another app of milo end of September when it rained again, the fungus grew out and most of the patches filled in. I put down Lesco winterizer 30-0-05 once the growth stopped, and now here I am.

Also forgot to mention I think I have poa growing in many places, big clumps - which is the primary reason why I don't want to use the Jonathan Green again, I'm pretty sure it came from there. The shady nooks seed I have read actually has some poa in it, and I used a small bag of that in a shaded corner of the lawn.

Thanks in advance, love the knowledge here and some of y'a'lls lawns are incredible!

There should be no problem with seeding a week or two after an app of tenacity.

 

[Jconnelly6b]

Are there any desirable grasses in a cool season lawn that are going to seed right now? I finally mowed today, and noticed quite a few spots that are going to seed, or seem to have already dropped some. I will be spraying Tenacity blanket app tomorrow.

First forsythia blooms appeared 2 weeks ago, still not fully bloomed. I have not used a fall emergent since I have had the house, as I didn't know about Tenacity until this forum and have needed overseed each year.

 

[g-man]

Could you post a picture of the seed head?

[FlyMike]

That looks like Poa Annua to me, but I'm not the best at weed ID's.

 

[Jconnelly6b]

After spraying Tenacity a week ago, I'm beginning some whitening of different grassy weeds. I guess ignorance is bliss, as I believe I am seeing quack, orchard grass, and even more poa annua than the 300 sq ft of it I already knew I had scattered throughout the yard.

Tenacity app was as follows: I have 13,500 sq ft of lawn. I filled the chapin 20V to 4 gals of water. Then I added 4 ounces liquid humic (it's all I had left), 3 ounces NIS, and 3.75 teaspoons of Tenacity. I used the 2 oz. per acre rate (.31 acres so .62 oz).

I already realize (thanks to g-man) I didn't use near enough water, should have filled chapin 4x, but oh well here I am.

Can I spot spray weed b gon, now, or should I wait to see if my Tenacity app has any negative affect on desirable turfgrass? I see broadleafs starting to poke through. I did not use any pre-m in the fall.

 

[ericgautier]

Looking forward to your journal.

You should be ok spraying broadleafs. I am battling some myself. lol.

 

[Jconnelly6b]

@ericgautier I must have missed the notification on the reply... here I am a week later and still wondering if I can spray broadleafs or not :roll:

I'll get some down this evening, it stopped raining.

Couple pics of the lawn - lots of grassy weeds to deal with - anyone can help identify? The purple at the bottom is probably poa t that was in that stupid Shady Nooks seed that I put down?

The last 2 are after my 2nd mow yesterday evening, of the nice parts of the lawn, which thankfully are in the front of the house.

Nice parts of the lawn are looking good! :thumbup:

Update:

4/7 - first mow @ 2.5", bagged entire yard

4/8 - dug out a stump from a 16" diameter tree, covered with topsoil. Municipality planted it in the steel cage... it kicked my ***

4/9 - Tenacity at 2 oz/acre

4/15 - Weed B Gone + crabgrass control spot spray

4/22 - prepared soil over used to be stump for seed, along with some bare spots from the dog. Seeded those heavy, and over-seeded rest of area with TTTF Hogan Blend. Fenced off area from dog. First time he was out in the yard, his 11 year old self hopped the fence, and put one paw into the damp dirt where I had just seeded, to show me that he knows what I'm up to, but it's his yard. He hasn't been over the little fence since.

Also spot sprayed CCO & used MSO as surfactant. Still not seeing much bleaching on clover, but the chickweed was already weakened by Tenacity so it's going pretty fast. Thankfully, as it's everywhere. \

4/24 - put down 3 bags of Sta-Green fast acting lime

4/29 - spot sprayed tenacity at 0.5 tsp/gallon on the poa and weedy grass. Hit the clover again for good measure.

Throwing a couple pictures in. Took these not long after sunrise. It was a warm humid night and I don't have any fungicide down yet, hopefully growing enough not a problem.

I have not fertilized yet this year.

 

[gregonfire]

Looking good man! Keep up the good work.

 

[Jconnelly6b]

Put down RGS and Air8 today. Mixed in Serenade as well - I see fungus on blades as we had 2 nights over 75F already.

I gotta be honest, I'm not super comfortable with liquid apps. This was only my second one - do they get better or do you always feel like you aren't getting it down that even?

I used 5 oz. RGS, 8 oz. Air8, and 2.66 oz. Serenade per gallon. 1 gallon/1000 sq. Ft.

I also just can't see how little droplets of solution on the blades are going to help aerate the soil? Hopefully my skepticism will be proven wrong, it was only a hundred or so bucks for all the products so if they provide any improvements it will be worth it.

Rambled a bit. Thankful for all the knowledge I've gained here and all of you.

I thought Air8 had to be in the soil, so spray it and water or spray before it rains. Then it does it's thing in the soil. RGS affects both the leaf and the soil so you spray that and let it sit and absorb the fulvic acid and kelp in the leaves and whenever it rains at some point, the humic acid and leftover kelp gets washed into the soil to do it's work there. I guess if you combine them and spray it without watering/rain, then it just takes longer until it rains to have an effect in the soil. Thoughts on this?

Red thread running rampant. Sprayed propicanizole on Monday evening.









Will be throwing down a granular fungicide this weekend.

What do you plan on using?

 

[Jconnelly6b]

@ericgautier not sure yet. Any recommendations?

@ericgautier not sure yet. Any recommendations?

I am doing some research myself. Only thing I have used in the past was Serenade. Have to see what the lawn has, if any, this Friday when I can get to mow again.
