Re: PGR + Cool Season Grass

Last year, I intentionally did this. I applied in late Sept and then we got a cold snap that stayed. The grass barely grew. I did not like it.

I think a better approach is to go half rate before stopping to avoid rebound.

Re: My first "real" fungus

Azoxy is effective against PB per Rutgers report. One of the images looks like BP, but I don't see the smoke ring on the patches. Regardless, azoxy should help with PB and BP.

Re: Parking Strip Irrigation

FYI, hunter also makes nozzles like this, but with less precipitation rate (ideal for clay soils). They are the MP strips (left, center and right). In regards to watering to cool the plants, the research is not conclusive around it ( syringing ). There are a ton of YT videos that show the effect las...

Re: Fall Seeding and Pre-em?

I think the best course of action will be to remove most of the weeds and overseed. You can do this with foliar tenacity (add nis) now to kill a lot of the weeds. Around the second week of August, throw more seed down. Since I think it is fairly bare, you can use KBG. The day you apply seed, also do...

Re: At what temp should I apply fall pre-emergent for kentucky Bluegrass?

In an ideal scenario, you want the prem active in the soil before your spring prem wear out. Too early is not a problem. I normally do around the first week of August.

Re: Centipede soil test - First time

Yes, 12lbs of KO2. Don't do more than 1lb/ksqft at once. Give it a month before you do another one. If using SOP (0-0-50), then you will need 2lb of SOP to get 1lb of KO2.

Re: Let’s solarize some bermuda and nutsedge

I think you should remove the covers and let it be for a week before applying gly. Gly works via foliar transfer on plants that are growing. I'd they are dormant, it won't work and they will be back.

Re: My first "real" fungus

That looks like pythium blight by the look in the first image and the gray looking in the middle images.

It spreads fast. Azoxy or mefenoxam for treatment. Try to only mow with it is dry to avoid spreading it with the mower.

Re: Is my backyard lawn worth saving?

BXMurphy your post is confusing. Wbg CCO will not kill crabgrass. bentz69 that product should work, but the % of ai is low, so it could take longer. They also sell the same product in a concentrate bottle. It will treat a lot more yard than the hose end one. I think you should kill the crabgrass no...

Re: Zone tripping gfci troubleshoot

I think you should replace the GFCI that is giving you trouble. They can go bad by either not tripping or constantly tripping. We are all supposed to test them monthly by pressing the test button. I'm guilty of not testing mine.

Re: Just got my soil test, any Advice?

@Cetnor851 I moved this thread to the soil folder.

Pretty good soil. It needs more potassium and it has a low CEC. A low CEC means that it can't hold to nutrients too much. More frequent applications at lower rates would be beneficial.

Re: Summer fertilizing

Nitrogen soil testing is not really useful. Nitrogen stays in the soil for about a month.

Yes the lack of color and growth, but more importantly it reacted in a positive way when you applied some in the test area.

Do 0.5 of N/ksqft now. Then start with the fall nitrogen blitz.

The images does show that you need nitrogen. The advise against too much summer nitrogen is for well established and fertilized lawns.

All those are good practices to avoid having to use fungicides. One of the main reasons I'm doing a renovation is to switch to a cultivar that gets less disease.

Re: New Home - Hydroseeded Lawn end of May

Tenacity with nis will take care of the crabgrass. You could then also use it prevent new weeds for 30day when you seed. I don't think you should nuke what you have. It looks like it could use nitrogen.

Tenacity will need a sprayer. For 10k, the ideal is 10gallons (1gallon/ksqft).

Re: How to Use Hot and Humid Weather to Improve Your Lawn

@john5246 some of these ideas are not what most members do. Sometimes the best course of action is to do nothing and wait for a better weather. Check the lawn journal from members to see what works or doesn't for them. Ideally from members near you.
