are you sure there is no chance the landscape people will make it right? Have you paid them in full? Some written correspondence explaining your concerns to see what their response is, before you pay them. thats the first thing that I would do.

Another option is to seed on top of the blanket. Realizing that you will not get as much soil/seed contact but as it over winters, snow, rain and frost will work the seed down into the blanket and hopefully to the soil.

I probably would not attempt to roll up the blanket myself just because its a lot of work, with all the staples etc. if the landscape company wants to fix it - that is what they should do.

Thanks for your reply. These guys have done work for me before, and our relationship is on shaky ground. Long story. Luckily, I have not paid them a cent, but I suspect things are going to get ugly before I do. I've been in contact with the person who helped me with the seed mix, and she is supposed to be coming out here to look at it. I'm not sure what she's going to see--how can they tell how much of the seed disappeared before the erosion blanket went down? If there is any chance of the seed filtering down through the straw, I like your idea--at least I can do it now without a lot of work. Got any opinion on when's the best time to do it? Wet vs. dry vs. right before a rain vs. right before a snow?

Its a shame that in trying to create something good, you have to go through this .
If you had an understanding with your contractor as to the procedure you expected them to follow, you have every right to expect them to perform as agreed if they want to be paid as agreed.
I would ask them what they intend to do to make this right.
Wait till they respond and base your next step on that.
Once they respond, I would at the least tell them to remove the erosion fabric to rake and roll the soil as agreed, and try to get them to add additional seed at that time.
while they have the fabric up, I would purchase more of a seed mix from a good local supplier and incorporate that into the soil as well before replacing the fabric.
Typically, the grass seed is the least expensive componant of the prairie seed mix, and you are better off underplanting grasses than over planting. Grasses can always be interseeded later.
The squeeky wheel is the one that gets oiled...
This does not need to be a disaster.

Well, I understand your conern and frustration. But there is not a lot you can do. If you were on shaky ground with before, you should not have hired them. For the work quality, there is no definite proof that they did anything wrong. I do not think that the contract will require them to inform you before they do their work. It will only make things worse if you have another person examine their work.

When you hire a contractor to do something that hard to judge, you'll have to take it or leave it. They might have done it right and you are just over-concerned. If they do not, the only thing you can do is not to hire them again.

Wish you the good luck..
