Blackberry Pruning: Removing Spent Floricanes for Cane Renewal

Blackberries have floricanes (fruit-bearing, die after harvest) and primocanes (next year's floricanes). Brown canes = spent floricanes. Remove them now, apply ¼ cup 10-10-10 per plant. Fertilize again with ½ lb 10-10-10 in March to stimulate new canes. Water during May dry spells before harvest. Fertilize again in June; water as needed through summer.
