If I want to aerate and lay down compost, how should I time that relative to Prodiamine?

I know I'll have to wait several months to overseed depending on the rate, but should I aerate and and compost now before prodiamine, now but after prodiamine, or down the road. Bermuda lawn in central texas.

I'm basically building this lawn from scratch, so I have the trifecta of a lot of weeds, shitty soil, and weak grass. The sections that I tilled, worked compost into, and seeded in early october look great, just trying to figure out the order to tackle things with the remaining section.

Definitely don’t aerate until the grass is growing really well.

June is probably the earliest you’d want to aerate and top dress.

Put down the Pre emergent now and fertilize every 4-6 weeks starting in April (actually see edit below).

Edit: “weak grass” - Skip the pre emergent until next year. Manage weeds with post emergent spray.

Too much going on in your post to figure out what’s going on. You’re seeding a Bermuda lawn? You previously seeded? You have a Bermuda lawn?

Sorry, let's just focus on the back yard. It was pretty much just clover when I bought it. I divided it into two sections with a wire fence to keep my dog from trampling the seedlings.

I did a first round of seed in half A of the back yard in June of last year. It grew, barely. Not a ton of sunlight and shitty soil. I continued trying to add seed to bad spots on side A. For side B, in October, I killed everything, tilled the soil, worked in compost and dirt booster, and seeded bermuda, and that side has been doing great. It never really went dormant. I don't think it even stopped growing at any point through the winter somehow.

So currently, I have one side (A) that has crappy soil, really thin, dormant bermuda, and the other side (B) has pretty strong soil and bermuda that never stopped growing. It does still have some empty spots that I'll need to seed at some point. Goddamn squirrels clogged my gutter and the roof runoff washed a lot of the seed out from where it was planted.

So I both previously seeded, but will also need to add more at some point.

One thing to note, horseherb is rampant in the creek behind my house, and that shite will take over in a heartbeat if I let it. Two rounds of 2,4-D kept it at bay last year, but hopefully prodiamine will help?

I would go ahead and do to side A what you did to side B. Skip the pre em and if horseherb is your concern then a bottle of msm will absolutely smoke it.

Prodiamine isn't going to prevent horseherb so my focus would be on getting grass.

So you're saying I should actually use glyphosate to kill side A and start from scratch now? Or just till it and work in compost as-is? And seed now, or wait for it to warm up a bit?

Then use MSM down the road AFTER the horseherb shows up?


I've got decent bermuda in the front lawn, can I go ahead and put prodiamine down on that? I was planning to aerate and put compost down on the front lawn as well at some point. I really don't want to spend another year pulling weeds by hand in my front lawn, so I want SOME kind of pre-emergent for that section. I also have a bottle of tenacity.

TYSM for the help man. I've learned a lot from you guys.

If you want to save what bermuda that side has then you can try to till around it. If its not much then I'd probably restart the whole thing. If the front looks good then I'd proceed as planned with the pre em.

Yes, MSM when you see the horseherb.

You dont need to kill the bermuda to overseed. That grass is resilient as hell. Just do what you need to do to improve the soil and add some new bermuda seed to it. Whichever is better between your old bermuda and new bermuda will take over in time but neither will thrive until you have good soil.
