We have two River Birch Trees (about 7 years old) that originally had hardwood mulch around them. Over the past couple of years the grass kind of took over & we would like to reclaim the area so we can remulch. Birch trees have lots of shallow feeder roots so it's been difficult trying to pull out the grass.
I'd like to try covering the area with newspaper & used coffee filters/grounds, plus some compost & then hardwood mulch. My hope is to kill the grass & nourish the trees at the same time. I don't want to use weed blocking fabric if I can help it because I want the nutrients from the mulch to get to the trees.
I don't know if I need to cut holes in the newspaper to allow water through. I definitely don't want to hurt the shallow feeder roots.
Have any of you had a similar situation? Has anyone tried a similar method?
