I totally agree obelixx. I also have long, cold wet winters (- and often cold, wet summers too!) and I can't understand why anyone bothers with Lavender here .
I find the best method for anything need sharp drainage is to mix plenty of grit through the soil and compost before planting, not dump handfuls of grit at the base of the plant which becomes a sump, as you rightly say. Many plants will cope with quite extreme cold if they're on the dry side, but cold and wet...
Flo - I often move plants when you're not meant to. If you get a decent rootball and you water them in well, they often barely notice. It depends on the type of plant as well though. Picking a cooler day for doing it usually helps. As obelixx says , it's best when they're dormant because of minimising stress but sometimes it can't be helped.
