Last year I had a fantastic harvest of Raspberries. My Autumn Bliss did me proud and were producing from August until the snow at the end of November
But now is the time to be pruning them back hard to the ground, as the new shoots of this year's growth are starting to appear.
If you've only got autumn varieties, then this is easy, - cut them all back, but if you have a mixture of the summer fruiting canes (which fruit on old wood) and autumn canes (which fruit on those green shoots, when they've grown into canes all in one season). Then you need to find those that have fruited.
You can be quite hard with cutting them back, - the new shoots come up from beneath the ground, so no need for long canes to be left. Just a sharp pair of secateurs and a slight angle so that any water drains off
In my personal opinion, Raspberries are the most luxurious of summer fruits, so if you have got room for a row of canes, plant some this year, - Autumn fruiting ones are the best and Autumn Bliss are my favs.
