I have two raised beds with wooden surrounds. I am leaving them 'bare' this Winter, but want to cover them to ensure the soil warms up quickly in the Spring. Should I use bubble-wrap, or black fibre glass sheeting - or something else?

In the past I have used black weed supressing membrane. as it is porous and the black warms up the soil quicker.

Hi Rod and welcome to GoY, you need to cover them with something that the soil can breath through so bubble wrap isn't a good idea. You could try old carpet upside down or cardboard - take a look at the permaculture site and you'll get lots of ideas.
