Last month I read somewhere (probably GW magazine) about putting down weed-suppressing membrane on ground not yet needed for crops, etc. Nothing new, and a fairly common suggestion.
However, does this really make sense in the long run? As I understand it, all the membrane does is suppress the weed seeds, so they don't germinate. Surely, then, when the membrane is taken off, they all shout 'Hip hooray! Here's light, let's get growing!'?
Why not let the weeds germinate, grow to a reasonable size and before they flower, harvest them for the compost bin?
