I have Bermuda in my backyard around 500 sq feet. It’s not doing as good as the first 2-3 years. I have about ~70 sq feet of one area that weeds took over and grass is pretty much non existent. Clovers starting to grow in patches in other areas. Should I over seed with Bermuda? Or is it possible to seed with another grass type?

With those walk behind aerators it's all about technique. I worked for a company using those for 2 months straight. First day I was dead, then once I learned the proper techniques of maneuvering and it wasn't much worse than just push mowing

Ryan, Last year I was about to scrape off my old lawn and have sod laid down. Then I watched many of your videos and bought your manuals on overseeding. I followed everything exactly. I had the most amazing lawn I've ever had. One I always dreamed I wanted. I can't thank you enough for the encouragement and sound professional advice. A million times better than any other "experts" on the web. Will continue this year. Love PR!!

Hey Ryan, appreciate all the content! Question about mowing post over seeding - will you wait until the new grass gets to a certain height, or when do you make the call to resume mowing? Thanks!

[@ryanknorrlawncare]

I'm watching this closely to make sure it doesn't get too tall. I may get out and mow it before I see germination but after that you just have to tread lightly on those first few mows and it turns out fine as long as you're careful.

[@ShaDowF50]

Good stuff! I’m about to overseed and follow this to a T! I have some pretty bare spots. Do you have any suggestions for dog traffic? I have 2 beagles that spend a fair amount of time outside. Should I fence off most of the yard(3000 sqft), or will they not affect the baby seedlings too much? Thanks

[@ryanknorrlawncare]

I would definitely limit traffic during the grow in or the new seedlings could be damaged fairly easily

[@michaelsima9186]

I have a great guy that aerates my yard for half what anyone else charges, but his plugs are only one to one and a half inches. The machine I used to rent pulled plugs much larger. Does size matter here?? Also, I think aeration is the best thing you can do to any yard. I’ve been doing it for over 30 years with incredible results. People are always stopping by and asking how much I fertilize and water and I tell them hardly at all. I also do the recommended things like cutting high when it’s warm and dry, mowing in different directions, keeping the blades sharp, etc.

[@ryanknorrlawncare]

3-4" if possible

[@rubenharris9241]

Great video Ryan, is it fair to say that if you had a lawn that was thin in the spring that you would focus on overseeding instead of pre-emergent? This was a difficult decision for me. I went the pre emergent route but have 1.25 bags of the RK Elite Rye standing by….

[@ryanknorrlawncare]

Fall isn't far away (in the grand scheme of things) so you could plan for that and get some great results then

[@killswitchh]

I used that Scotts turf builder this spring with my overseeding and it's doing a great job. Dandelions and clover come up and turn white pretty fast. Crab grass seems to get through though.

[@Craig-ib7gk]

re: your crabgrass: Quinclorac. Make sure your turf grass type is in the "highly tolerant" list (ex: PRG is highly tolerant; st. augestine is NOT). Two applications two weeks apart per the instructions and manufacturer rates should be enough to quell your crabgrass. I use a surfactant to make sure it 'sticks'. Do not mow 2 days prior to application. Do not irrigate for 24 hours after application. And, do not apply in hot temperatures (right now, most of the country need not worry about that).

[@simonamaral9904]

Great content as usual , I like that deflector you have on your spreader and was just wondering if that s something you can order by itself and if would that fit on a Earthway spreader ?

[@brianinnes597]

Huge Poa Annua problem in my lawn. My plan for fall '24 is: Level, aerate, over seed and Tenacity in late August/early Sept. and then Prodiamine as pre-emergent for the Poa, late Sept/early Oct. Thoughts on this? I did a preemergent of Prodiamine this Spring for Crabgrass, but I would still be under the annual limit. My concerns are with the newly growing grass which will be 5 ish weeks established at this point, and with the combination of Tenacity followed by Prodiamine. Thanks!

I want to do this process of overseeding this fall in ND. Would it be a waste in the fall rather than waiting for spring next year? My lawn is a bit thin, I'm sure it can use a dethatch session, and so many different weeds spread throughout the grass, with a handful of weedy bare spots.

I just tilled my yard a few days ago. Im wanting to lay gras seed to grow a nice yard. My dirt looks nice and dark. But i have a question, do i NEED topsoil to grow grass? Or will the dirt i have be good enough? (West texas dirt) lol

[@ryanknorrlawncare]

Grass grows in many different soils but how well it survives is going to be the key. It always needs nitrogen and water so you start there but a soil test could also help to figure out if you need other nutrients to help. ryanknorrlawncare.com/product/rx-soil-nutrient-analysis-kit/

[@MrMadeinthe80s]

Nice shirt! Wish we got more content from The Rebel.

[@michaelAMaccarr]

Ryan, this does not look like your backyard

[@tvercel]

Really good info Ryan! Curious how effective the overseeing might be when you have a 100 percent KBG but want to start to convert to your ryegrass. Would this result in a patchy look or would it allow even coverage. Would the rye win out or would the Kbg dominate. Northern IL. Cheers!

[@ryanknorrlawncare]

Kbg will definitely still be there but if thin out the blue pretty aggressively you could make it more rye heavy. My old front lawn was actually never fully 100% removated so if you go back to some of those older videos you can see what I did. It was originally bluegrass sod.

Hey Ryan, I've been binging your channel lately! Great content and production quality. Question: Just bought my first home WITH A YARD. Beyond pumped.

For an established/old lawn: would spraying humic acid prior to laying seed be beneficial?

[@TheLittlep3]

Would you recommend applying a fungicide before hand more so when overseeding?

[@pillcosby3949]

Yea I’m curious as well.. I want to overseed kbg but I feel like I will just create fungus with the rest of my healthy grass, due to the amount of water needed for the seeds

[@slowjett7343]

If you don't have a drag device, would it be better to aerate first and then power rake afterwards in effort to break up the cores? Does the order of operations make a difference in your experience?

[@ryanknorrlawncare]

That could work. Depending on the machine and your soil it might tear up the tines but I have used my other scarifier after aerating with some success. The drag was better for sure but it's an option.

[@Aletorba]

I want to overseed my cool season lawn this month but dethatch/scarify instead of aerate, what do you think?

[@ryanknorrlawncare]

You can but just make sure it's thinned out enough you can see down to the soil layer so the seed can reach it. A topdressing in that case would certainly help too

Starter fert works best after the seed has germinated. Most of the the nitrogen will be gone before the seed pops

[@JoseDiaz-bk9mh]

Everyone talks about cool season grasse and warm season grasses but what about us guys in the middle/transition zone. I’m in lower North Carolina for example. I know nothing about lawn care so I watch videos to learn but everyone seems to treat lawn care as either living in Michigan or in Florida. What should I do in NC? I’m not looking for a perfect contest worth lawn. I just want it to be nice to look at. It’s pretty much all clover and crabgrass at the moment.

[@ryanknorrlawncare]

Transition zone means you pick either cool season or warm season grass but neither works perfectly. There is no "transition zone" grass type so that's why no one talks about that because it's same grasses we have up north or south depending on what you choose. Most in NC have fescue and overseed in fall if summer damage occurs from heat.

is there a reason to be concerned when doing a dethatched during the spring time?

Cool season grasses are coming out of a stressful time in winter so thinning them out too much or when things aren't even green yet can be tough to recover from before summer heat
