Blackberries are well adapted to our sandy soils, making them a very productive fruit to grow in Florida.
Fertilizing: Use a balanced fertilizer such as Espoma Plant-Tone three times a year in February, May, and September.
Pruning: Blackberries tend to become rampant if left unattended, so a good pruning just after harvest will keep it from becoming overgrown.
Plant Problems: Blackberries have a few fungus and pest problems, but typically cutting old canes out of the group takes care of this.
