1. I tried to find an answer for you but couldn't, good luck with that!
2. In your zone the Bluegrass is less hardy and more apt to die off on its own. In the future, should you desire, make sure the seed mixture is both certified and contains no bluegrass seeds. Again, in your zone, the bluegrass should not exhibit the problems it does from its origin. The disease and fungi problem will, if it presents itself, be minimal and eliminate that grass. I would, however, to protect myself, overseed with a different variety of both the fescue and ryegrass in the spring and fall, to provide for continued health. I am biased based on results. I truly love the Manhattan 2 Ryegrass. In Combination I would use a Red Fescue. For your area I would suggest 75% Man, 25% Red, and %25 Midnight Blue. I added the bluegrass as it is an outstanding variety if you can find it. If you can't use a Rebel or Falcon Fescue in it's place. Be advised that the water and nutrient needs of the mixed lawn is far greater than that of a single or dual type of turf. Like the Rye the Blue will need more attention. It will also give you a golf course look when maintained. The Fescue is a hardy turf which does no want water, fertilizer, and does not present itself well when mowed. With a mix you have the best of both worlds. Irrigation minimimum as the fescue will be green. Fertilize and the Rye and Blue will respond. A specific disease or insect directed toward the Fescue, Blue, or Rye, will not wipe out my lawn. Go to a true and hardy fine grain Fescue for any reseeding. Any K31 generation is a clump grass that kills rye and bluegrass. It is great on a football field. Do you want a football field or a turfgrass lawn?
3. The Canada Bluegrass you mention is also called "poa annua". It is an annual variety of bluegrass, that is most of the time, undesirable in the home lawn. Golf courses use this grass mainly in their putting greens. In order to keep it looking good, you need to mow on a regular weekly basis. If you don't, the white seed heads appear and give the lawn a ghastly white hue over the entire lawn. There are a couple of ways to control this. One is to keep a diligent mowing practice and the other, which is the most desirable and sure fire way, is to use a pre-emergent herbicide in the fall and winter time. This will kill any seeds that have fallen into the turf waiting to germinate. I have provided a link explaining this process as well as some good info on this particular species of grass. Hope this answers your question.. Good luck! http://www.indmowing.com.au/poa-annua.htm http://www.turffiles.ncsu.edu/news/weeds/07sep01poaannua.htm ...Billy Ray
