Question by sewkid: How to tip Thorn-less Blackberries and Black Hawk Black Raspberries?
When tipping Thorn-less Blackberries and Black Hawk Black Raspberries, can I tip the second time when the new shoots are 12 inches long? Also, are starts coming from canes better then ones coming from the seeds of the berry, or can I just split the root system?
Answer by fair2midlynn
When your top cane tipping, you're actually developing a clone of the plant you had. Berry seeds will many times revert back to berries that produce thorns on the canes. I usually tip mine in the fall when they're about 2 1/2 to 3 feet high.
