I have been told by a friend that I can grow garlic as long as I keep it under cover. so I am going to give that a go, but any other suggestions will be welcome.
just for clarity's sake, is that fahrenheit or celsius/centigrade? i know many of the figures thrown out in this thread have been in F, but i'd guess in cardiff, you're probably generally using C? just so we're actually using the same language
as far as garlic goes, even at -10 F, with decent mulch it should
be fine over the winter without plastic. it's pretty hardy stuff.
