Thank you. What about a post-emergent herbicide for a lot of broadleaf weed pressure in a newer Spring lawn that was seeded in the previous Fall (Oct l. 1st). It is now late April 2024, can I apply Seedzone at a reduced rate after three mowings?

Great info. I seeded in the fall and will take your advice on avoiding preemergent for the year and just do spot. We’ve had a lot of crab grass and clover issues last year but I’m thinking about just managing that until the roots grow in. Also since I’m not doing preemergent should I overseed again or is that just overkill? Over all the lawn looked a lot fuller in the fall. Would you do a video on how to water, fertilize, and weed control on a lawn that was just seeded in the fall?

Spring seeding can be successful, but in my experience, it's better to wait until fall. The results are definitely better. I can also say from experience that proper turf maintenance can go a long way in helping compete with weeds. I have seen a pretty dramatic decline in Wild Violet, Creeping Charlie, and crabgrass over the past 2-3 years and have not used any pre or post- emergents. Can't wait for lawn season 2022!

Wild Violet and Creeping Charlie showed up out of nowhere in my neighborhood last year. Nobody knew what it was or where it came from. I spent the entire Summer and Fall trying to get it under control. Ironically, the weeds that used to be a problem (Dandelion and Crab Grass) were almost non existent.

[@82hilljh]

I have a question. I did a dormant seeding late last fall using some your KBG product from your website. This is the first time I tried dormant seeding. I live in the mid-west, so the temps dropped low this week. When the temperatures rise, is it ok to apply a liquid post emergent herbicide to the entire lawn? Or, do I spot treat the weeds? Or, do I need to wait until I start seeing some of the grass from the dormant seeding appear. The broadleaf weeds, and other weeds, are starting to appear-especially where the grass meets the concrete.

[@ryanknorrlawncare]

I would spot spray but know that whenever you seed it's recommended on most labels to not use any herbicides until the grass has germinated and you've mowed 2-3 times.

[@jakemalek3395]

so if someone did a dormant seed on thin areas right before winter in Minnesota would it not be wise to use a pre emergent in those areas if they actually get decent germination and a chance for the grass to become mature and part of the existing lawn?

According to what I heard Ryan say, yes you could use tenacity early in the spring and a second round if necessary. Then overseed in the fall. Didn't think prodiamine is recommended or necessary for fall as temps are declining and crabgrass needs warmer temps. You would be using contact or systemic weed killers in fall after the young grasses have matured and can handle chems... At least that's what I'm getting out of the vid.

You can use it but it won't have the same kind of effect as prodiamine does in terms of creating a barrier in the soil that lasts for months and is extremely effective when applied correctly and watered in.

I did a lawn reno last fall with 100% KBG. Will the spreading really begin to take off in the spring with regular feedings? I'm trying to figure out whether I want to overseed or use a pre emergent. It isn't very thick yet, and there are several areas with minimal grass due to washouts.

[@ryanknorrlawncare]

It will probably take until next fall to get it looking really thick and kbg like. It's very slow but spoon feeding it helps a lot.

Hey Ryan, 100% KBG lawn installed mid September, rooted well, last mow mid November in CT. Is it ok to apply barricade at this time for spring?

[@michaelzielinski7703]

Mostly asking because the sod is super thick and my thinking is to maybe let it just take off and not risk inhibiting deep root growth this spring.

[@ryanknorrlawncare]

I would let it mature during the spring on its own without barricade

[@michaelzielinski7703]

Thank you so much for getting back to me. This was my thinking exactly to let the roots get as established as possible and allow for maximal seam filling. Thank you for all your videos and information you provide every year!

I over-seeded in the fall in mid to late September here in Kansas, the weather turned quick and there are several areas I’m a little worried about. I have been wondering if I should spray pre-emergent or not. I’m thinking about putting down some more seed, especially in the areas that look thin, and spraying pre-emergent on the ditches and edges of the lawn where the crab grass and sandbur pressure was last summer. Should I put tenacity down for the rest of the lawn and overseed a week or two later? Or vice versa?

[@ryanknorrlawncare]

Wherever you decide to use the tenacity I would do it close to the time of seeding.

@@ryanknorrlawncare I follow the recommended time to keep my dog off the lawn after applying tenacity. Have you had issues with dogs ingesting grass and getting sick? I’m just trying to keep the pup safe. I go beyond the recommended time frame of 4-6 hours. I usually wait 48 hours before I let the pups back on the lawn. Just looking for people’s experience with tenacity and dogs. Thanks.

Did your neighbor buddy who you helped with his yard move away? Looked like a "For Sale" sign in his yard from that drone footage in the fall. That would be interesting to see how a new owner maintains that yard now that it is in tip top shape!

[@ryanknorrlawncare]

They moved but I doubt the yard will be maintained. :(

Great information 💯

No pre-m for me this year. Thought I had fungus issues cause i couldnt figure out why after water the lawn it looked dry the next day. Turns out I have clubbed roots. Just gonna be me and the weeds this year.

[@dspdante]

Have you done any pre-germination or seed priming? I’ve done a few small batches this spring with great success. I’m planning an 11,000 sq ft renovation for the Fall and am wondering if I can have similar success with a large batch of seed.

Hey Ryan, I've got dirt at the moment and my builder is going to Hydroseed. I want to put perennial rye grass at the same time they Hydroseed. Curious what your thoughts are on this? Can I carpet the ground with seed do you think?

[@wally7856]

You could always contact the hydroseed company before they show up and give them your seed to use. They mix the slurry custom for each job, no reason they couldn't use your seed instead of theirs.

[@keepingupwithcamden8580]

@@wally7856 I asked, the builder won't put me in contact with them...

The exact video I needed

[@kevinkane3434]

Hey Ryan, great info. Is putting down the pre-emergent a one time spring application or can I wait 30 days and put down a second application of prodiamine? Hearing conflicting opinions on this. Thanks for all the information.
