Q.winterize ‘limelight’ hydrangeas
My Limelight hydrangeas bloomed in abundance this year. I would like to know the best way to protect them from the Okanagan’s winter cold. I have applied leaves then a thick layer of mulch chips. Should I cover them with hemp sacks that I have? Also, should I clip off the deadheads or leave them until early spring and THEN prune my plants?

At this point in time, I would leave the pruning till next year, just so you don't inadvertently bring the plant out of dormancy.
I don't think that the hemp over it will help much, as that is more to protect from wind and drift damage, but you can use the hemp to create a barrier around the plant that you can then fill loosely with leaves for added cold protection.
