Water new plants regularly for their first growing season – in dry spells, water every seven to ten days. Well-established plants shouldn’t need extra watering, although if the summer is particularly dry then watering once a fortnight will increase the fruit size.

Pruning will also increase air circulation around the plant, minimizing pest and disease issues.

Pruning can accomplish different purposes, depending on what time of year it’s done. Pruning essentially sends messages to the plant to release certain hormones that make it grow in a particular way. Trimming the plant while it is dormant, for example, will affect growth differently than trimming during the growing season. In the late winter or ear...
Gather Your Tools
The equipment required for pruning blackberries is simple. Pruners, loppers, and gloves are all you need. I use a pair of bypass pruners like this one, which provides a clean cut without compressing or tearing the plant. For thicker branches or canes, you may need to use some bypass loppers, such as these(which I use). The longer handles allow you to cut thicker growth, using more force with less effort. Gloves aren’t as essential with thornless brambles as they are with thorny ones. But in e...
Dormant Pruning
Most blackberry pruning should be done while the plant is dormant. Depending on the climate, the plant may or may not lose all of its leaves over the winter, but it will stop growing. The best time to prune is right as you start to see the buds swell, or just before, in the late winter or very early spring.
Pruning During the Growing Season
Once the warm weather hits, the blackberry plants will start growing. The 2nd-year floricanes will produce leaves, branches, and blossoms. New primocanes will grow from the base of the plant at the crown.
There are two ways to prune fall-bearing blackberries. The 1-crop method is the simplest, essentially removing all second-year canes and leaving only the primocanes each year. But, this will result in the plant only bearing fruit once during the season in the early fall. The 2-crop method allows fruit to grow on both second-year canes in summer and...
When pruning thorny blackberry plants, it is essential to protect hands and arms with leather gloves and long sleeves. Thorny plants sometimes produce more vegetation and canes than thornless ones, so it may be necessary to do more thinning of the plant.
Below is one of my ‘Navaho’ blackberries before dormant pruning: And here is the same plant after pruning, following the steps above: The canes have been thinned at the base and tip-pruned to about 42 inches, and lateral branches have been shortened.
Summer-Bearing Blackberries
1. IN LATE WINTER: Remove dead or diseased canes or branches. 2. Keep the strongest 4 to 6 canes, trim the rest to the ground. 3. Tip prune canes to be 36 to 48 inches long. 4. Trim lateral branches to be 12 to 18 inches. 5. For trailing blackberries, re-attach to trellis as needed. 6. IN SUMMER: As canes grow, tip prune to be 36 to 48 inches long (or the height of the trellis wire) 7. IN FALL: After fruiting, trim spent floricanes to the ground. Shorten remaining primocanes as needed. 8. Cov...
Fall-Bearing Blackberries
1. FOR A FALL CROP: Trim or mow down all canes in the late fall after fruiting. For a larger harvest, tip prune during the growing season once the canes grow beyond 3 feet. 2. FOR A SUMMER AND FALL CROP: Remove dead or diseased canes at any time (including 2-year-old floricanes that have already fruited. Keep primocanes over winter, trimming length as necessary, so they will fruit the following summer.
Aug 25, 2022 · When to prune blackberries. Blackberry bushes require two lots of pruning throughout the year to keep the plant healthy and its size in check. ‘You should first prune your blackberries in early spring,’ advises Rachel Crow, garden editor for Homes & Gardens.
When to prune blackberry and hybrid berry. Pruning for blackberries and hybrid berries is usually carried out after harvesting in summer or autumn. As the new canes start growing the following spring and summer, they need to be tied into their supports.
Jun 13, 2024 · 1. Prune part of the stem. When planting a blackberry vine as a rooted cutting, prune off two-thirds to three-fourths of the handle or stem, leaving only a short crown behind. Doing so stimulates the buds at the crown of the cutting, encouraging them to grow more vigorously.

What happens if you don't prune blackberries?
Blackberry plants should be pruned in winter or early spring (when dormant) and in summer after fruiting. Everbearing or fall-bearing varieties should also be tip-pruned after the fall harvest. Pruning at these times will improve the plant’s health, control its size, and increase fruit yields.
