My neighbours front hedge is wild and untamed. A blackberry bush has been thriving in it for the last few years and this bush produces the world's sweetest, tastiest blackberries which my dc love eating in the summer - every time they walk past it they pick a few.
This year I've had some raised beds built and the dc want to grow their own blackberry bush but only if they are the same as the neighbours.
So how can i get a bit of their blackberry bush and transplant it into my garden? Google only talks about how to plant blackberries bought from shops, not cottages from the wild (before anyone panics neighbours have said we're welcome to help ourselves)
