Kill weeds in large area - cover the weeds in tarp?
Is that an effective way to kill weeds in large area? how long would it take?

I've heard that in early spring and late fall black works better because then the greenhouse effect isn't strong enough to bake the plants, and you benefit more from the light blocking of black tarp. In late spring through early fall, clear works better because plants will bake. I have no idea if that's true, I did read it online and it makes intuitive sense but I didn't bother - I used landscape fabric, planted through it, mulched over it, then the next year I removed the fabric.Mars2012 wrote: ↑ Look up "clear or black plastic for solarization" and you'll get this:
In general, transparent or clear plastic is most effective for solarization, as the heating rays from the sun will pass through the sheet and be trapped to heat the soil below. Usually black plastic is less effective because it absorbs and deflects part of the heat, rather than trapping as clear plastic does.

For years, I thought black plastic would be best but did some research a while back as was quite surprised that clear works better.
Solarization, when done correctly, will also cook some or most of the weed seeds in the soil...something that herbicides can't do.
