Last year, we installed landscape fabric beneath most of our oldest row of high-density apples. The idea was to cut weeding work...but I'm afraid the plastic mulch also appears to be cutting vitality.

It's hard to be sure whether the fabric is at fault because I have several different apple varieties growing in this area and there's some fireblight in the mix. But the apples that were mulched with straw are thriving while those amid the landscape fabric have lost most of their leaves.

I suspect water is the culprit --- or lack thereof. Summer rains tend to fall hard and fast in our area, meaning that a lot of that liquid likely runs off the landscape fabric despite the small holes meant to allow rain to soak through. In contrast, straw grabs and holds the liquid, topping up the trees' reserves slowly over the course of several days.

I've pulled back the fabric so I can topdress with manure, and I'll probably end up replacing it with a biodegradable weed barrier of cardboard coated with straw. If we had an irrigation system that hit these trees, the plastic might not be a bad idea. But, for now, I'm going to stick with what works.
