Cardboard even in the rain?
Yeah it only has to last a few weeks. But if you think the soil stays moist enough for carrots to sprout - or maybe it has something to do with the darkness too?
Look it might be a corny oneness hippie thing, but on a really big level, being up and close with the earth you're going to be part of again in the form of dust ain't such a bad thing. There are worse ways to spend your time, like being an evil mother fucker genociding like a demon and raping children, you know?
Will give the cardboard a go. Might create the perfect environment for them :)
I am not a "walk barefoot" kind of person, but I don't mind getting my hands dirty.
Both seem to be in trend...
You don't need to walk barefoot, though I definitely do (though it's getting cold in Vic now!) Getting your hands dirty, well, that's good enough ....
