|I live in Georgia & I planted 2 thornless blackberry plants in August 2007. Should I prune them before they start to grow this year or is it too late?
|It's not too late to prune but things will be easier if your prune in both fall and spring next year. To maintain your plants, in the fall, prune out all canes that bore fruit, shortly after harvest. (It?s advisable to dispose of all clippings, either by burning or taking to the dump. Dead canes can spread disease.)
In the early spring, thin canes to about 5 - 7 per plant.
Prune side branches on remaining canes to about 12 inches or 12 buds.
Tie the pruned canes to your fencing.
As with raspberry plants, you can prune broken, dead, diseased or infested canes at any time of the year, the sooner the better.
Hope you have a bountiful harvest!
