Don't do it! No no and no again.
Here's why: I used to do yard work in my MIL and FIL's yard. From 1998 through maybe early 2007, I weeded, trimmed, pruned, etc., once a month. Then, in early 2007, FIL was diagnosed with a terminal condition. He had been the full-time caregiver for MIL, leaving him no time to work on the yard, which he had loved doing.
We lost him in April, the same month that I *finally* had one of my knees replaced (they both needed it, but one at a time). So, no gardening for me for a while.
BIL, wanting to make the in-laws' yard a low-maintenance (and much neater) situation, hired a landscaper. Said landscaper put down yards and yards
and YARDS of polypro weed cloth.
When I got back into gardening, in mid-2008, weeds had started to come up through the weed cloth.
How-some-ever, pulling them up by the roots was very difficult. I couldn't dig them out anymore, like I had previously, because that would tear up the weed cloth. Pulling the weed from on top pulled the weed cloth up from the ground, leaving unsightly ripples. Etc.
Now, five years after the [dratted
] stuff was installed, it has finally loosened up enough for me to get ALL of EVERY weed I go after.
And life is good again for me, bad for sow thistles, dandelions, invasive Yellow Star thistles, etc. Oh, yes: foxtails, and weeds whose names I don't know, but I do know they're bad news b/c they make my skin break out if I don't "suit up" for battle with long gloves, long sleeves, long socks with pants well over the socks, hiking boots, head scarf, etc. So yes, the weeds are bad weeds (yerbas malas) and they don't like it when I show up.
But the weed cloth is an ongoing pain in the patootie. I cannot fertilize the hydrangea or give it a good soaking. The ferns are dying due to lack of water (can't soak them, either).
Don't do it.
