Weed cloth under fig tree?
I'm sorry if I seem to be posting a lot, but I'm rethinking so much to do with my fig trees.
When we planted the fig tree in-ground out back, I was told I could put weed cloth under it to discourage nutgrass and other weeds from growing. I had also put layers of newspaper beneath that, but was told to get that out of there because it would smother the fig tree roots.
I'm wondering if the weed cloth would smother the fig roots. The water goes right through it and I can see right through it. It doesn't stop some of the nutgrass (I HATE nutgrass!!!) and some of the fig roots were growing through the weed cloth. The soil beneath the weed cloth was damp, as I'd watered the tree yesterday, but it wasn't wet, or soggy.
I took the opportunity to check some of the little roots that pulled loose when I peeled back the weed cloth and they look very nice--no sign of RKNs that I could see. The soil smelled so rich and loamy and is black and loose. When we planted the tree, I spread potting soil in the hole and all around the tree after it was planted. The the newspaper was spread under the tree and then the weed cloth. When I was told to remove the paper, it had already begun to disinigrate, but there were mats of it left, as well.
I also put cypress mulch on top of the weed cloth to hold in moisture and keep down weeds.
I'm wondering if I've acidified the area around the tree too much and should I put a little lime. It's got to be very acid with all the pine/cypress products I've used and our soil tends to be acid down here to begin with. If I need to tame down the acidity, what would I use and how, for an established tree?
Any suggestions for me? I don't want to overtend the tree and kill it that way, but it will wilt back in the sun a couple of days after I water it. The drainage is good as far as I can see. It's not in a low spot and the water does not sit in the soil, or puddle up. I'm missing something, though I'm not sure what.
Are there some South LA boys who can advise me as well?
Thanks so much,
