I've grown Tulameen for a good many years. It is Summer fruiting and a good cropper. Cut the old fruiting canes out every year and tie in the new ones. Try to keep the width of a raspberry row at no more than 18 inches by removing straying canes. Last year thanks to all the rain my crop was fantastic, but if your site is waterlogged try making the raspberry row higher. When I first bought my canes they were advertised as being the same sort sold by Marks and Spencers.
