Tried just about everything for weed control. When associated with a community garden, some un-rented plots were covered with very wide black plastic. They soon became big black balloons from the foxtail grass under it. Have had success with glass storm windows over small beds. Otherwise, think Christmas and hoe, hoe, hoe! No bad plant survives steel.
Yes; nothing non-herbicidal beats chewing them up, one way or another, I don't solarize; I rake the dry weeds off (this is the season), sic Sukie on them two or three times, until they stop rearing their unwelcome heads, and plant. This is, admittedly, a bad year, so much having been left fallow during recent drought, but that process will destroy the weeds where I need to, long enough to reclaim the areas.

You may notice from my photos i use silage cover plastic, black one side white the other. I use it for killing off weedy or grass areas black side up so it basically cooks it, also its used for when i want to sit bird nets on when covering seed crops that way weeds dont grow through the net. Using clear plastic though would only be effective at frying surface weed seed during high sun periods, but then how deep would that heat penetrate?
