Which side of weed block should face up?

DoubleJ · January 20, 2009

I have the best weed block around. At work, we cover large bundles of lumber with waterproof tarp-like material. I have one cut into 18" wide strips and plan to tack it down over the walking paths of my tomato beds. The question I have is, one side is black and the other is white. What side should face up? The black will warm the soil a bit but, it's just the foot path. The white may reflect some sunlight onto the plants but, will cool the soil under it. What to do?
