Yes it will be ok, the tree height will be restricted by the pot size. I grew a flowering cherry in a large pot 18" across and 24" tall. Use John Innes No3, not multipurpose compost and make sure it is kept well watered and gets a feed as it will soon exhaust the nutrients in the compost.

I kept mine growing like this for 4 years before I planted it in the garden I had. The tree will be ok.

many things are possible my friend has an adult giant sacoya thats 3` tall in a pot with the rest of his 50 or so bonzei . the bigger the pot thow the happier the tree as bonzei need reguler attention .

Unless you have a very large garden a big tub is the best place for a cherry tree. There are 3 cherries just down the road from us and they need tree surgeon attention every other year to keep them under control.

you can cheat and cut the bottem out of your pot so it looks like its in it but it can still put its tap roots down etc . i hav a 6` tall weeping cherry that would be ideal . in the 14 years ive had it its just got bushier and thicker . it was know shorter when i baught it for 310 . WHAT A BARGAIN . THE GARDEN CENTRE I GOT it from is closed which is a shame . i went one day with a weeping tree in mind and as i walked out the back i sore a couple looking over the best bye far cherry tree out of the lot . they hummed and hard for ages so i just paid at the till and went and said excuse me and took it from under there nose lol . i guess if you snooze you lose lol . its on one of my blogs of my back garden if youd like to look .

£10 sorry lol .
