POLYTUNNEL MEMBRANE-OR NOT ?

Mares tail can come through tarmac so membrane won’t stop it. My plot was riddled by it & I got very uptight abought it, I already knew the saying never let it see a Sunday. But on researching more I read to let it grow to 7-10cms then trowel & gently pull it up. The theory is it will have expanded lots of energy into growing & by pulling up gently you get more root & over time you weaken it as it can’t photosynthesise without light. This approach has really worked for me & I now just see less every year, more this time of year but less as the year progresses.
