I planted a 12' row of raspberry plants and they grew wonderfully. I enclosed them with railroad timbers thinking that should keep them out of the rest of the garden. No such luck. I eventually took a chainsaw and cut them down then painted each stump with weed killer; a systemic that would kill the roots. It took a while but eventually they all died. I was really bummed as I really love raspberries. I may try the bucket idea and use very large planters. I bought some from Costco that looked like whiskey barrels and were 18" deep and about 30" across the top. Made of a heavy rubber. I wouldn't bury them and might even put some sort of metal pad under them to assure they didn't somehow dig their way out. Would I only be able to plant one in each bucket? And they would have to be fertilized regularly to deep producing fruit?
