Hi Wayne.
Good question. I don’t know of any lawn bowling club that has covered their greens for the winter. I know that one fall at Burlington they reseeded a large patch on their south green and covered it with a piece of cover they got from a local golf course. The part that was covered was more advanced than the rest of the green in early spring.
Some golf courses use them and some don’t. Hidden Lake covers their greens every fall. They are the only one around here. I will ask around and let you know.
If you can afford to buy the cover and have the manpower to install it, I am sure it would work well but it is not cheap to buy and not easy to lay down on your green. It has to be well- secured to last the whole winter. If not, then with the first wind storm it will be gone.
Hope this helps.
