Seed & start
Perennial
Plant once, returns every year.
Stachi's tip
Blackberries spread AND prickle. In a raised bed only a thornless variety ('Navaho' for example) and with a root barrier. 2 m wire trellis is a must. But yield is spectacular from year 2.

Planting blackberries in a raised bed this autumn: why one plant can already be too many
Frau Schneider ordered three thornless blackberry plants for her kids – all three meant for one single raised bed. I had to tell her that even one of them will outgrow it eventually. Here's what actually matters for an autumn planting.
