Myths About Growing Blackberries in Scotland

“All blackberry canes are thorny, so growing them means accepting the scratches”

Several AGM varieties are specifically bred thornless. Loch Ness has upright thornless canes, and thornless canes are a stated priority of the James Hutton Institute's own blackberry-breeding programme, which bred Loch Ness and its successor Loch Tay for exactly that trait.

Our read Wild bramble is thorny, and that reputation carries over to garden blackberries generally, even though the varieties actually worth planting have mostly bred the thorns out.

What to do: Choose a thornless AGM variety such as Loch Ness or Loch Tay rather than assuming thorns are unavoidable.

“Cut back all blackberry canes in winter the way you would with summer raspberries”

Old, fruited canes are pruned out at the base as soon as harvesting finishes, any time from then until late winter — not held back as a single winter job. New canes that haven't fruited yet are kept and tied in for next year's crop, not cut back.

Our read The instinct to do all pruning at one point in winter is reasonable for a lot of fruit, but blackberries reward pruning out spent canes as soon as they're done rather than waiting.

What to do: Cut fruited canes out at the base straight after harvest, or any time up to late winter, and keep this year's new, unfruited canes tied in separately rather than pruning them back too.

“Blackberries carry on ripening after picking, the same as some other soft fruit”

Blackberries won't ripen any further once picked, so fruit needs to be fully ripe on the cane before it's worth picking at all.

Our read A pear genuinely does finish ripening off the plant, so it's an easy assumption to extend to other fruit. Blackberries don't work that way.

What to do: Wait until fruit is fully ripe and dark before picking, since an under-ripe blackberry stays under-ripe once off the cane.

“'Loch Ness' is just a catchy name for a blackberry variety, with no real connection to Scotland”

Loch Ness was bred at the Scottish Crop Research Institute, now the James Hutton Institute, in Dundee — genuine Scottish breeding provenance, not a marketing name. Its successor, Loch Tay, continues the same naming convention after another Scottish loch, the same pattern as raspberries' Glen series and blackcurrants' Ben series.

Our read It's easy to assume a variety name is just branding, especially somewhere as recognisable as Loch Ness. Here the name reflects where the plant was actually developed.

What to do: Treat the Scottish breeding history as genuine background, not as evidence the variety performs better in a Scottish garden specifically — that's a separate claim Hutton doesn't make.

“You need two different blackberry varieties for pollination, or a lone bush won't fruit”

The great majority of blackberry cultivars are self-fruitful and will crop from a single bush without a second variety nearby. A small minority of cultivars are self-unfruitful and do need cross-pollination, so it's not universal, but the general rule for garden blackberries is that one plant is enough.

What to do: Plant a single named blackberry cultivar and expect it to crop on its own. Nearby bees and a second variety can nudge yield and berry size up, but neither is essential.
