Hi I lost my cotoneaster this past winter it never came out of winter dormancy. The place I purchased it from said it was the way I overwintered it. I live in South Central PA in zone 6b. I had read online to place it in an unheated garage or shed so I put 1 inch ridged foam insulation around the pot and placed in shed where it still received light I had a thermometer in shed and the temps in there only got down to 10 degrees a couple of nights but it did get warm in there several days because the winter was weird with warm and cold weeks. The place I bought it from said I should of brought inside for winter but their website has it listed as deciduous so it needs the cold exposure. They are located in southern California and said tree never saw temps below 40 degrees. I purchased a new tree to try again so I'm looking for suggestions on how to care for it this winter thanks
