It’s actually not. We have entire regions covered with vines. We can’t wrap the whole France in plastic, it’s just not possible. But we can predict where it’s going to freeze and when, so we take such measures on very specific zones with precise timings. So this only happens a few times a year, at precise locations and not for long
We have much better ways of protecting crops from frost including reusable netting/row covers with supplemental heat from electric heaters. However they cost more so…
Seems to be worse ecologically

It’s an old cheap method.

Electric heaters are wasteful. How about spending that energy wisely while also generating heat?
