The forecast is showing yet another five days of wall to wall sunshine ahead. :( If we ever get a decent amount of rain I'd like to think I could make the most of it by mulching to keep the moisture in, but I haven't really got any organic material left. What would you suggest for a quick and effective (andpreferably free or cheap) cover on both planted and unplanted areas? and are spent hops any good, as I've seen some on freecycle?
