Primocanes are topped at about 6' to encourage branching. However, these branches are not usually further pruned, but are trained on the double T trellis. We see tremendous yields with this production system, without an apparent loss in fruit size. Dead floricanes are removed after harvest. Irrigation, as for all the blackberries grown in Oregon, is usually done with moveable overhead impact sprinklers.
Harvest is done by hand in early morning.
Fruit for fresh market are rapidly cooled, often by forced air and are packaged for shipping. Again, most of the seeds must be removed as they are much larger than those of 'Marion', for example.
