I have never used weed block fabric, and never will, I hate the stuff. But, many people use it, so people have different opinions of it than I do. My neighbor just gave me several hostas she had for over seven years, they were the size of one year old plants, and they had never multiplied. When I dug up the plants the weed fabric had prevented the roots from growing more than a quarter of an inch deep,
I can't imagine trying to put that stuff down with plants already established, that has to be a nightmare. If it was not put down before the plants where planted then I just don't see it being feasible to use at all.
It is suppose to block the weeds and let the water pass though, but you see how well that is working, how about when the dirt and mulch wash on top of it and the weeds start growing? It is a mess, even with mulch on top, the weed seeds will still germinate in the mulch. Trying to fertilize the plants will be a problem, don't know how earth worms will do, I didn't see a one while working in my neighbors yard that has the weed fabric in the beds.
Sorry, I am of no help, but you followed the instructions, and that is about all you can do.
Found this article that answered a few of my questions and reinforced my opinion of weed fabric, but said it much better than I can.
