Will Brought in an expert and he verified the triv plague. It has horizontal growth and when it gets tall, it falls over showing brown under-growth. Actually pretty in the early spring when its short (beware) It grew unbelievably fast and the expert said if I didn't act quickly and decidedly I would have to contact a golf course to use one of their greens mowers. So it was 2 rounds of Roundup at least 18" past the known edge of the triv. Used my power rake to pull up the dead turf. That was almost a mistake because the viney triv kept wrapping around the spindle. It worked out OK because I had a perfectly contoured base for replanting. I live by Michigan State University and they have a wealth of "Green" info. We prefer to use "Spartan Grade A". Its a Kentucky Blue mix with some drought resistant/ winter resistant strains. Works for us Yankees here. Good luck Mark

First impression using the Chapman 20v is that it was really great. Performed as expected. Not too heavy when full. Straps seemed strong. It was comfortable on the back. Quiet. One disappointing thing that I experienced and that I have read somewhere else before is that the cap is really difficult to deal with. Cross threading with a bad seal is easy and even if you think you have a good seal nice and tight, well, product splashes and leaks from the top. You need to be VERY careful. I used blue dye and when I took the backpack off, the back of my shirt was wet with blue dye. Luckily the Prodiamine didn't make it through to my undershirt, but I rushed off to the shower regardless. Be careful of that cap!

Tony, what is the name of the pre-emergent you used? Is it a weed & feed fertilizer type? Since you said that that you applied two rounds of pre- emergent, I am of the humble opinion that either it was applied incorrectly or the product you applied did not work at all. I use a pre-emergent called "Prodiamine WSG65" with excellent results. WSG stands for water soluble granules. It is a very effective product and the efficacy lasts for up to 6 months. So if this product is applied in early May, you get the protection until November - by the time the window for crab grass seed / or any seed germination is past. Crab grass seeds can be viable for up to seven years and will lie dormant until the right conditions for germination arrive. If you don't keep up with the timely pre-emergent application, they are certain to come back. Apart from pre-emergent application, mowing high & letting the grass clippings back into the lawn, fertilizing the grass as needed etc. will also help. The whole idea is to not provide the favorable conditions for weed seed germination. Hope this info helps. I have fought this battle and won. I have very few weeds in my one acre lawn. This forum has helped me a lot in winning this battle. A big thanks to all the active posters in this forum.

Cannot tell. They don't show the guaranteed analysis on any of their pictures. It must be on a label on the back of the bag. If you could take a pic of the back of the bag or somehow get the guaranteed analysis, then we could help you. In the pictures it looks like a creeping red fescue. Tell us where you live and post a couple pictures of your yard and we can get you going. One thing to note is that spring is the second worst time of year to sow grass seed. Summer is the worst. If you plant now you are going to have a yard full of crabgrass by July. That is because spring is when crabgrass seed germinates. If you put your grass seed down and water it, the crabgrass will germinate first giving you the impression your target grass is coming in. Spring is also a bad time because the roots of your new grass will not be hardy enough by summer to make it through the heat. So for these two reasons, you will have a crabgrass lawn by July. Having said that, at least crabgrass dies in late fall...and at least crabgrass is green in the summer. Late summer is the best time of year to renovate a yard. If you just want to maintain grassy weeds until fall, we can help you do that, too. I still would not use that Canadagreen seed without knowing what is in it. The most important thing to know after that is where you live.
