Hi there! I'm Farmer Jill, and I've been growing berries, including lots and lots of raspberries, for over 20 years. People call me the Berry Queen because I've gotten so good at producing these delicious and nutritious fruits!
Pruning your black raspberries is an important part of keeping your plants healthy and productive. It can seem a little confusing since you don't prune all raspberries the same way. Here's what you need to know about when and how to prune your black raspberries:
Understanding Black Raspberry Growth
Black raspberries grow a little differently than the more common red raspberries. Knowing the difference is critical for proper pruning.
* Primocanes: These are the <font color='red'>first-year canes</font> that emerge from the ground. They grow tall and vegetatively, meaning they focus on leaf and stem growth. They won't produce any fruit in their first year. You can identify primocanes by their light green color and active growth.
* Floricanes: In their <font color='red'>second year</font>, those primocanes become floricanes. These canes are thicker and darker than primocanes and will flower and produce the tasty black raspberries you're waiting for! After fruiting, floricanes die.
When to Prune
Black raspberries need two types of pruning:
* Summer Pruning (June - August): This pruning encourages lateral branching and more fruit production the following year.
1. Pinch the Primocanes: When your primocanes reach a height of about 24-30 inches tall, pinch or cut off the top 2-4 inches of each cane. This will encourage the cane to develop side branches, called laterals, which will ultimately produce more fruit.
2. Control Suckers: Black raspberries, unlike their red cousins, don't send up suckers all over the place. They do, however, produce new canes from the base of the plant. If you want to limit the size of your patch or prevent overcrowding, thin these out, leaving the sturdiest canes.
* **Dormant Pruning (Late Winter/Early Spring):**
1. Remove the Floricanes: Once the floricanes have finished fruiting, they're done. They won't produce more fruit and will only take energy from the new primocanes. Prune them down to the ground, removing them completely.
2. Thin the Primocanes: Not all the primocanes you left from the previous summer will be strong enough to be productive. Select 4-6 of the strongest, healthiest primocanes per linear foot of row and remove the rest. Canes should be about the thickness of a pencil and spaced about 6 inches apart.
3. Tip the Remaining Canes: Once the threat of severe frost has passed in late winter, tip the remaining primocanes (which are now technically floricanes). Cut them back to about 4-5 feet tall. This will keep your plants from getting too tall and top-heavy, making them easier to manage and harvest from.
A Note on Tools
* For pinching the tips of primocanes, you can use your fingers if you're comfortable doing so. Otherwise, a clean, sharp pair of pruning shears or scissors will do the trick.
* For removing floricanes and thinning primocanes, you'll want to use sturdy pruning shears or loppers, depending on the thickness of the canes. Make sure your tools are sharp to prevent damaging the canes and spreading disease.
Enjoy the Fruits of Your Labor
Pruning black raspberries may seem like a bit of work, but trust me, it's worth the effort. By following these simple steps, you'll ensure that your plants stay healthy, vigorous, and produce an abundance of delicious black raspberries year after year. And that's a reward worth working for! Happy growing!
