Nothing spreads like kbg, if its not spreading its probably underfed, it likes 4 to 5 pounds of nitrogen per season or not getting enough sun.

Search here for siletz, there's a recent reno that you can see pictures of it.

 

I am fairly sure it got 0 pounds of nitrogen the last few years with the previous owners. I have done two application of fertilizer so far, both at about 1 pound / thousand, so about 2 pounds total on the lawn so far. Not really seen a ton of spread, think I should be pushing it harder?

 

rye and fescue don’t spread. Stick to the kbg

 

I have used the RPR before and I was not impressed by its lateral spreading ability. It was also on the lighter green side which is common for the Barenbrug varieties. My opinion, push more N to your kbg and let it fill in.

 

Sounds like you have irrigation. I would spoon feed that kbg and water. It takes time to fill in.

 

It should have filled in during one spring with 2 lbs. N. Mine has.

Can you post pictures?

If you do not overseed, I would definately push an aggressive N blitz in the fall and see what it does.

 

@robjak Sure thing! Here are some photos. Mostly thin on the corners.

 

first thought, more tall fescue than kbg in the mix. But i am not an id expert.

Do you have irrigation?

 

Yes I do have irrigation!

 

Are you in transistion zone? North Carolina?

 

No, in Colorado actually

 

IP shows VPN / North Carolina.

i would fert next 2-3 weeks. 0.5 lb N each week and water in. If it does not spread, then plan the Rye for a late summer overseed.

 

Yeah, I see more tall fescue than kbg in there. Looks like you have a general cool blend. With irrigation, I would keep up with the 0.2# nitrogen every other week or so through the summer or whatever your temps say is possible and then in the fall go heavier. A soil test wouldn’t be a bad idea since the lawn is new to you. You might need just nitrogen, but if it hasn’t been taken care of by the previous owners it might need more than that.

 

Thanks all! I will keep up some light N over the next few weeks and keep checking progress. Will plan an overseed if I still have thinning issues. Looking more closely I do see a good bit of fescue like you all said. I wonder if perhaps the original sod was KBG and a variety of seed has been put down over the years.

 

It’s not in bad shape at all. I would keep up on the nitrogen as long as your temps are cool, start pushing it again when the temps cool back off, and if it is still thin I’d overseed with some rye to fill.

 

Thanks @casts_by_fly! Any thoughts on what temp is too hot for Nitrogen? Been getting pretty hot here (80s) but still getting down to the 50s at night. Grass is still green and growing for sure.

 

Here is once from Pace Turf, but ther are plenty of others out there with a quick search. What I'm not sure is if that is soil or air temp. Once you start topping 80 degrees though the growth potential is dropping fast to 'just don't do it' levels. If your lawn is growing well and you're cutting it regularly then that's the important part. Follow it's lead.
