Why Are My Blackberry Plants Not Growing Canes?

Question

I purchased thornless blackberries several years ago and they just don’t grow any canes for berries. At best the plants 6″ high. I conditioned the soil when planted and keep them watered in the hot summer. Soil drains well. They just stay close to the ground. What can I do to have them grow upwards and produce fruit?

This could be an overall set of nutrient deficiencies, or pH imbalance. I would recommend testing the soil for nutrient and pH deficiencies and amend accordingly. These articles will help:
