5 mil silage tarp for occultation?
I'm prepping a new quarter acre block for production and I've been battling Canada thistle. My plan had been to so oats and field pea cover crop until it in but the thistle keeps coming back so quickly I think it will outcompete a cover crop at this rate. I'm leaning towards tarping sections off and trying to exhaust some of the thistle through occultation. Online I've seen 8, 12 even 14 mil silage tarp and it's expensive. I saw it recommended to just buy it from your local Farm Store to save from the shipping cost. My local farm store has silage Tarpon sizes I'd like and much more affordable however it is 5 mil.
Does anyone have experience with occultation using silage tarps this thin? I get that it probably won't last as long, but is this thickness still workable without being too precious with it? Thanks in advance for any feedback you might have
