Your best time to overseed is the next 3 weeks. I wouldn't put out any lime now. Best bet is to have a soil test done to determine if you need it and if so, how much and which kind. Personally, I wouldn't drop any fertilizer now either. Wait until the new grass is up and it's been mowed a few times, probably late September. Otherwise, you're just going to be feeding any weeds that are already there helping them to compete with the new seedlings. Then towards the middle of November put out a dose of fast release nitrogen to help it get through the winter and green up sooner in the spring. When you do overseed, water the new seed 3 times per day very lightly. This means about 5 to 10 minutes depending on your sprinklers. If you do this you should start seeing germination in about a week. Continue this watering schedule for 2 to 3 weeks and gradually back off of the frequency and increase the amount of water each time.

Well, it's day 7 now for my Kbg reno. I don't see anything coming up yet.... I'm not too worried yet as I don't think it's too unusual to not see anything yet on day 7 Day 7 is very early. Relax. Keep telling yourself that it takes 21 days. :) but at what point, what day, do I consider it a total failure? ... If by day 20, Sept. 15, I don't see anything, do I still have time to try it again (rake, reseed)? Or do I wait longer than that? Don't worry. It will come in before that. The first little bit of mine started to come in at day 8. Since then it has been slow torture. It is now day 15, and the first areas are starting to knit together, others are just starting, and there are still a couple of bare spots, but it's a little better each day. So hang in there.

1) Depending on how much water your system puts out, you might not need 40 minutes. But other than that, sounds good. The once a day watering is meant to let the top of the soil get just a little dry for a few hours a day to start strengthening the roots and letting more oxygen into the soil structure. But it's not critical. If it doesn't happen now, it'll happen at the once every other day watering. 2) Either-or. Starter and soy will play well together, and the soy's nitrogen availability is gentle but constant. The starter is more of a flash in the pan. If I recommended starter due to a low phosphorus level, it's probably more important to get the P flowing in than worry too much about overfeeding (which really won't happen anyway).

2 year update! The Turf Blue bluegrass has adapted very well to the NC environment. Disease has not been an issue - which is refreshing, and the cultivars in the mix are very aggressive - they filled in 6" holes left over from dead Bermuda in 6 weeks. The relationship with this mix has been a bumpy one. There have been periods when the grass looked lime green and I've seriously considered nuking it, but the fact it's so resilient stopped me. Meanwhile, I've learned to work with it, and it with me. I've learned that cutting below 2.5" produces some sort of reaction in the grass and it starts to put out massive amounts of new lime-green growth. As soon as I stopped trying to go lower and stabilized the HOC at 2.5", the color issue went away. Also, color has improved with age. And finally, PGR and FAS bump up the color significantly as well, bringing it into the acceptable range for my taste. Drought tolerance is similar to fescue, maybe slightly less. However, recovery from dormancy is outstanding, so even if it browns a little, it comes back with a vengeance. And where it doesn't, it spreads to fill in. It's peace of mind, and it's priceless. Because I know I can afford to push it and let go a little brown, I probably used less water on this summer that I used to use on fescue. Disease has not been an issue, brown patch doesn't touch it. So, I'm going into my 3rd years with the HGT mix. I am very pleased with its performance, and I expect even better now that it's mature. Color can be successfully managed, and it lives up to the H in HGT. Highly recommended as an alternative to fescue for the Transition Zone. http://lawniac.com/wp-content/uploads/2018/11/lawn_oct_2018.jpg
