Seems the answer is no, nobody has tried it. I do think the idea has merit, they use this technique for Bermuda fields every year in cattle country. To make it work with bluegrass the timing would be more sensitive--Since the heat will affect KBG, you would probably have to do it very early or very late in the season.

J4c, you're a nut. :) But, you're posts often lead to interesting concepts and studies. Thank you.

On the issue of sprigging KBG. What would be the advantage? Kbg seed is cheap. Seeding results are extremely successful, cultivation practices necessary for germination would be no greater than those needed for sprigging, establishment coverage is higher than sprigging (see the video in your link) and no need to bury or cover the seeds as is required for sprigging.

HOWEVER, BELLA KBG is EXTREMELY interesting. I've never heard of it. A slow growing no-mow, dark green, spreading, low nutrient maintenance, drought and shade tolerant grass that will flourish in zones from 4 to 8? Snake Oil! B.S., but apparently true. Unfortunately, it can only viably be established by sod, sprigging or plugging. Still it just might be worth the effort and expense.

Kudos to you J4c, for posting this. Thank you again.

I agree it's questionable how useful this could be in the home lawn. I was thinking that maybe you could apply pre-emergent faster with sprigs than with seed and I'm not sure that that's the case. If you seed KBG you're looking at 3 weeks for germination plus 60 days before you can apply pre-emergent. If you seed Mid-August, you can't really apply pre-emergent until November. That's generally too late for Poa A control. If you can sprig and apply pre-emergent 30 days later, it's a different story . But again, I'm not sure that's the case, I don't know how fast it takes root.

I saw another video where they were harvesting KBG and it said the new crop just comes back on its from the roots left in the ground. I guess I'm just surprised KBG is that aggressive, I'm used to fescue.

Here is the patent application describing Bella. It includes a NTEP style comparison of Bella with a number of well known KBG turfs.

The only bad thing about it is the wide blade and the necessity of plugging or sprigging to establish, of course. Only 12% of its seed germinates and it is such a poor seed producer that it would take 24lbs at a cost of around $720 to seed a thousand sq feet. I wonder what it would cost to buy a tray of plugs and have it shipped?

I had a feeling sod solutions would be the distributors & sure enough they are. $60 for 70 plugs.
