Cut the one-year old canes which have produced this year’s crop all the way back to ground level after you have harvested the fruit.
Leave between 10 to 12 new canes (this season's growth) per plant that will bear next season’s fruit. More may result in over crowding and a reduction of light and air circulation.
Trim the new canes back to approximately 8 inches in height. This will boost growth of next year’s new shoots and improve your loganberry crop.
Watch for disease or die back during the growing season. You may need to remove shoots or canes that become infected or die back as they are unlikely to bear fruit and may spread the problem to other parts of the plant.
Watch for pests during the growing season. Consult with your local nursery as to what treatments can be safely used on or around the plant as you will be eating these berries and don’t want to use something that would be dangerous to consume.
