How to tip Thorn-less Blackberries and Black Hawk Black Raspberries?

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?

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.

  1. While you could use the prunings from “tipping” to clone your plants, it’s primary purpose is to produce greater yields.

    These links have recommendations for pruning.
    Raspberries produce fruit on 2-year-old canes, which die after the crop has matured. The pruning of black and purple raspberries consists of:

    Tipping the new canes when they reach a height of 18 to 20 inches, thus forming a branched cane that is capable of producing more fruit than an unbranched cane. Branched canes are also more able to support the crop off the ground than unbranched canes.
    As the buds break in the spring, the branches on the canes should be shortened to 8 to 12 inches (longer if the plant is supported by stakes or a wire trellis).
    After the crop is harvested, the old fruiting canes should be removed at the soil line. (The removal of the old canes as soon as the crop is harvested is a good disease control practice since it removes an important source of infection.)
    “Black and purple raspberries are pruned three times a year: in the spring, summer, and after fruiting (Figure 3). First pruning is done in spring when lateral branches are cut back to 8 to 10 inches in length in mid-March. Second pruning is called tipping or heading of new canes or primocanes. When grown without supports, summer tipping is done when black raspberry canes reach 24 inches in height and when purple types reach 30 inches. Tipping is done by removing the top 2 to 3 inches of new shoots as they develop. Third pruning involves the removal of canes that produced fruits, right after the harvest.”

    As for propagation
    “The easiest way of propagating blackberries – and other hybrid berries – is by tip layering, which is best done in spring or summer.”
