I layered some brown (thin) craft paper and then leaves to help kill the seeds. The wind had it's way with the paper but I think it still did a decent job. I'm hopeful that the combo breaks down and improves the soil and also helps block weeds.
The 1-2" soil above is a garden mix soil so it's a step towards mulch. Still, I'm certainly adding soil. I'm hoping it further ensures the weeds stop growing.
I know they say avoid piling too much as it suffocates the roots. But I'm hoping I'm not going too far? What's the difference between this and a forest continuously having leaves, branches and other items decomposing over time? Or even folks mulch around their trees?
Where is the line drawn between hurts and okay or even helps the tree?
I'm looking to plant some native understory ground cover like wild ginger, common violet and wintergreen. Im hoping it is lower maintenance then the mess of weeds. I certainly don't want grass.
Any advice appreciated.
