re: 2022 Lawn thread - Post your pics, updates, questions, etc.

I wish I had some before pics of how sorry my lawn looked in 2020. Right before my hours and pay got cut due to covid, I had an estimate done to re-do my sorry looking bermuda lawn in the back yard. Just as I was about to pull the trigger to pay around $5K, the bottom fell out and I cancelled just in the nick of time.

In mid 2020 and early 2021, a neighbor to the left of me and a neighbor to the right of me had some fairly large trees cut down which had been supplying some significant shade to my lawn. Since then, I haven't changed much of anything; same pre-emergent, same weed control, etc.

Pretty pleased where the lawn is today without any additional costs...

Is it safe to core aerate this time of year or is it too late? My soil is pretty heavy clay, so I want to aerate then toss some mason sand to level fill holes....centipede lawn if that matters.

The LSU AgCenter’s recommendation on lawn aeration is to do it when the grass is in active growth, usually starting around May (south LA) - your lawn grass is in active growth so it would just fine/safe to aerate and fill low spots now.

Just the occasionally directed spraying of killzall.

I don't but what I do is make 2 passes with my Ryobi 40V.

Weed ID help. Is this bushkiller? First pic are small ones that have been popping up in the yard. Second pic is growing vine that I pulled out of a flowerbed. My flowerbeds are relatively small so easy to spot and pull, worried that it’s popping up in my grass. I’ve read these are a bitch to eradicate, any tips?

It does look like virginia creeper. The only difference is creeper leaves are all roughly the same size. Brush killer has a bigger leaf in the center and four smaller leafs.

Can I apply iron and propiconizole at the same time? I have gray leaf spot and skipping fertilizing.

Yes

I need help with a weed ID.

Can you post photos of the problem weed(s). There are some weeds not controlled by Celsius or MSM - Dallisgrass is one that comes to mind; certain crabgrasses are another

Can I spray a 2-4d product when temps cool?

---

Yes - upper limit is 85 F for 2,4-D products; when afternoon temps cool to 70s is probably ideal

Fall pre emergent timing ? Granular

---

South Louisiana - mid-Sept to early Oct - apply before soil temps cool to 70 F - temperature at which many winter weed seeds begin to germinate. Granular - Dimension or Prodiamine are good pre-emergents available in granular form. Also available in spray versions, which are cheaper on a per 1000 sq ft basis.

Craw, do you think it’s southern watergrass? Looks like it to me.

Op, is that a low spot that retains water?

I want craw to look at it considering southern watergrass. I’m 6 years removed from dealing with it. If it is then it’s a nuke and start over. It’s not on the level of torpedo grass but you’ll have raise the level of your lawn and push the water elsewhere
