Citrus for zone 8b?
I'm not sure yet, but I am considering moving down the mountain... all the way down to USDA Hardiness Zone 8b. It seems the recommendation for most citrus is no colder than zone 9... So, can anyone recommend some good varieties for 8b? Or, can you recommend some strategies to, as David The Good says, "push the zone".... half a zone should be that big a deal... heck, Sepp Holzer grows citrus in the Alps! Am I correct in thinking that some deep mulch and a sunny, wind protected location would probably be sufficient?
