Replying to Tips for Skiing Heavy Powder

Save for the occasional trip out west, I predominantly ski/tour in central Ontario and when we get a snow dump there it's often on the heavy side. Toss trees into that and I really fall apart with my technique. Any tips for getting better at skiing the deep and heavy stuff? I grew up focused on on-piste carving, so getting into glades this past year has thrown me (literally and figuratively) because the technique is so different. I had an easier time of it at Revvy in January because the snow was drier and more forgiving.
