    I passed out flyers a month ago regarding Core Aeration and Overseeding. And, now a few customers would like to know is it too late to core aerate & overseed?. I told them no and I can do this weekend. But, what do you think?.

    do it. tell them they will see the results in spring. after coreing, hit it with 25-5-10, at 8 lbs per k. in april when the lawn is thick, green, and growing 2" a day, they will think you are a genius

    Bob, I'm not a LCO genius. But, I did stay overnight in a holiday express reading LawnSite! :laugh: Thanks for the info, LCME

    I dont know much about your climate up there but you cant be much colder than us right now here in PA. In theory, the books tell us that aeration causes stress to the grass plant and that we should not do it much past mid October so it has a chance to recover b4 cold temps set in but I've done them as late as end of October and the turf recovered nicely. Of course you dont want the seed germinating anyway this late in the season and given your climate will get cold soon. As BG said just tell them the seed will come up in spring(at least some of it)

    My only concern this late in the year (and being in Michigan) would be what type of seed are you planning to broadcast, ie, sun or shade mix. Shade mix will predominately have a greater percentage of fescue vs what you find in a full sun mix. Fescue takes longer to germinate. Get my drift?

    If you or your customers are expecting instant results (like in 5 days or so), you might be disappointed. Otherwise if it's ok until the spring that you see results, knock yourself out this weekend and do it.

    I try to quit one month before the first expected frost date...which is tomorrow. I might do a few more next week, but no longer than that.

    8 lbs. per k!!! What in the world? If that is quick release, you will have WAY too much growth going into dormancy. I'm sorry, but I just have to disagree, here. It DEFinitely doesn't need that much right now, nor should it have that much. I DO agree with going about 1 1/2 times the rate in spring, AFTER it starts coming out of dormancy on it's own, but that is with a 50% scu. (Actually, we use 24-5-11, and/or 24-0-12). Growing 2 inches a day is certainly not what we are trying to achieve. What I do is grow grass super thick and dense, but still have a slow to moderate topgrowth. If you want a recipe, let me know. You can PM me. I'm not far from you. I can show you properties around town that we do that other services don't even come CLOSE to for density and health. I am glad to help.

    runner, 25-5-10, applied at 8 lbs per k, only delivers 2 lbs of nitrogen per k! that's too much? i think not. if i need 4-5 lbs of nitrogen per k,per season, and 80% of that needs to go down in fall, i need DOUBLE WHAT I STATED. look, fact is, i'm sure i couldn't hold a candle to your ass when it comes to this, but the courses i take, through the d.e.p, taught me this. do you think this is wrong? excess nitrogen, without the other factors needed to grow grass (temps, etc) will not "force the grass out of dormancy", but rather the nitrogen will be stored for spring use. this is my understanding. applying 80% of the total nitrogen very late in the season has also helped me to avoid fungus on these properties that are prone to fungus and disease. how many lbs lbs of nitrogen are you using a season? i know rain/drought/irrigation will cause you to change/alter the program, but on average, how many lbs, and when are they applied?

    Our first aps are heavier than usual, about 1 1/2 times the rate. If we are using 24-5-11, it's 50% scu, so it's only getting around 3/4 lb. per m, BUT it's getting an additional 3/4 lb. after that. By the time the other 5 aps. are done, we end up at around 5-6 lbs. total. As far as the 2 lbs. of N in one dose, yes,.. that's too much, unless it's a real slow release like a Novex form or something. It is especially alot right before it is going into dormancy, because it can cause a late flush of growth which can lead to snow mold among other problems. Your thought on giving it N right before dormancy IS the right idea, though! This will help a green-up in the spring - on it's own, as opposed to how alot of other co.'s do it and "zap" it out of dormancy by hitting it with a quick release in early spring - one of the worse things you can do for it. If done right, it can be done in the fall and you can STILL have the first green lawns on the block. Just as grasses start coming out of dormancy, we go in and cut (or tell the customers who cut their own or have them cut) to cut it down low one time. The grass then just explodes out of the ground, and wa-la, we have the greenest yards on the block. One of the REALLY most important factors is the storing of the potassium. Again, you're right on with the higher potassium rates (I thing you were right around 10). This encourages good vascular health in hardening off which helps the dormancy comeback, AND certainly improves the root stimulation both now, and again in the spring. I hope this helps.
