Plum Tree advise please

B&Q are selling Victoria plum trees for about £10,they are grown especially for small gardens it says and grow to about 13/16 feet in height.
Can i grow this in a big pot of about 55cm in width or does it really need to be grown in the ground.
It says its a heavy cropper but when i asked the man there he said it would need to go in the ground as i wouldnt get many plums if grown in a pot.
Im sure he knows his stuff but i thought id ask some experts?
Thanks in advance

The roots like to spread as wide as the branches, so I agree you'd need a very very big pot 

At 13/16 feet it's not on Pixy dwarf rootstock    only a semi dwarf one, so not really for a small garden at all IMO

can't you stick it on the edge of the lottie

I have a plum tree growing in a 25 lt pot. But next year it will be put out in the ground. I would not expect it to grow very big in her. At the best you could maybe squeeze three pies out of it. If you do a Google image search for Redcurrant bush, you will see some in large pot, that is probably a good indicator of spread; although, plum trees may grow a bit bigger.

There is a Victoria plumb tree near me in a hedge-row that is maybe 5 ft. high and has a lot of comp. for space, but still has a decent yield of about 2 pies. If I was growing such a tree in a pot, I would use at least a 100 lt one.

How about if i gig a hole next to my compost bin and path which is a gap of about 2ft,which is where i was going to put the pot,would that be too restrictive too do you think.

hi

that would be fine. my dad just dug a hole though the tarmac and rubble layers on his drive way and grew a plum against his kitchen wall. so as long as you feed it and it gets water - i think it will do pretty well.
