For some reason I am having trouble uploading the other photos in my original post. Here is another image of the lawn.

With that level of germination, once a day, or maybe even better only when the grass calls for it (maybe every three days? Four? Six?), should be fine now in your climate. Whatever seeds you sowed that have not germintated by now just won't, at least if your photos are any guide. I don't know what grasses are in patchmaster, but if there is a significant KBG component (doubtful, but possible), or even a significant amount of creeping red fescue, the KBG will overtake those areas in the fall with no problem, and the CRF will do its best, but more slowly. Also, if your seed did not have a high percentage of KBG, you might consider overseeding when the weather turns, which up by you should be like this week! And if that doesn't work, your next best option is to seed over the winter (really), after the cold temps set in but at a time when the lawn is not covered with snow. If you are curious about this, google "dormant seeding." Cheers, Paul

"I'm not sure I agree with the idea that the lawn MUST be re-seeded, unless the OP has decided he wants a KBG lawn. The Perennial Rye that was in the original mixture will eventually predominate over the KBG, so he will end up with a mostly PRG lawn. Some people do go that route. Not sure what the recommendation is for upstate NY." The perennial rye cultivars in that mix do not spread. Any bare areas now will be bare in the fall unless some of the KBG made it and starts to spread. I said anything that survives into the fall should do well, but how much grass is left at the end of August is anyone's guess. There is nothing wrong with a PR lawn, they look great, and are easy to overseed if need be. Upstate NY is KBG country, and if it gets too cold PR can die off due to cold kill, but I have read this isn't as much as an issue as once believed. I happen to think monospecies lawns are easier to start and take care of regardless of what type you pick. My whole point is this; 2500 square feet isn't a lot of area to seed again. Most of the work has been done. Instead of having a weed filled patchy lawn, kill everything and do it over. The grass will do much better, the weed pressure will be minimal, and the lawn will be very consistent and thick into the winter.

Where do you live? What is your watering regimen (frequency and duration)? Can you take a picture of the edge of the remaining grass from a distance of 3 inches? I need to see the blades of green grass and blades of any yellowing/browning grass up very close. You're getting plenty of light. St Aug grows very well in full shade as long as it gets light from somewhere. For example it will grow poorly under the low canopy of a magnolia tree but it will grow fine under the canopy of any tree with bottom limbs 6 feet high or more.
