Project this weekend to perform major surgery. -E Do you think it's snow melt that's causing this problem? I ask because I know of a few people who've had that problem with other plants in the past. They're in free-draining spots but there's just too much moisture to get rid of. Hi Sacha, I really don't know what causes it. But I've tried some _really_ dry places. Currently they're against a south facing wall, quite near the base, in a slightly raised bed. For sure they don't like great amounts of snow, but I wonder if they weren't weakened the previous winter. For the OP's sake, though, these have survived at -22C (well probably a little above that because of the wall). Though as we all know there's a lot of difference between surviving and thriving! The great advantage when the rosemary gets really big is you can use huge amounts with impunity. We very often grill over a wood fire in the big kitchen fireplace; adding some rosemary branches at the end will cause the coals to flame up and smoke like crazy, which gives a wonderful smoked-rosemary flavour to meat. -E |

And some do better than others. The one we know as the Salcombe rosemary here - the very, very, very long one that trails on for ever, is as tender as can be, as is R. Severn Seas. But R. Marenca has come happily through the winter here in one wall and died off in another 3 feet away, in the same type of soil and height etc. I can only assume that the dead one was not a good plant or that there's some little pocket of water that collects underneath it. Anyway, it's now an ex-rosemary. Ah, many of us here remember the famous Salcombe rosemary. And the accompanying "discussions" For sure there are a lot of varieties that perform differently, though. I lived in San Francisco for a few years, not too far from Ocean Beach, there were many rampant rosemaries, not used in the kitchen and I'm sure not hardy here, but still wonderful smelling when bruised.

[] I've had meat cooked over vine prunings to the same effect - delicious! I recall friends of mine in France (Haut Beaujolais) had an Albizia julibrissin which thrived in their garden for years but one year the snowfall was particularly heavy and by the time it had all melted, the tree was dead as a doornail. I've had trouble with that one. I planted it in what I hoped was a very drained hillock, but it died back more and more over several years and I finally took it out. Haven't tried again as it was quite dear. These do very well on the coast in sandy soil though, don't seem to mind the salt. I put a Davidia involucrata a few feet over, it's hanging in although it didn't appreciate the snow, either. -E |
