you definatly want them out of direct sunlight or to much direct sunlight and in a shelterd place . apart from this therequit hardy in that respect ie cold weather etc . im sorry im know good at latin names but most acers grow to about 12-15 feet and grow quit wide to . there are some low ground covering acers and trees ofcourse . im sure someone like bamboo who is more in the know will tell you the rest .

Oops, Np! Pauline got Acacias, not Acers.
Pauline, unless you are in an exceptionally frost-free area in the UK, you will not want to plant them in the ground at all. They are only hardy to -3.9º C. They could be an indoor/outdoor plant, as long as they got plenty of sun. If you want to risk planting them in the ground, put them on the south side of a stone wall, which will help moderate the frost.

i did think you said acers i do apologise glad you read my answer so you could sort that out before it all got confusing lol .

good old dyslexia . i remember seeing a van driving alongwith bit advertising writing on the back window . i thaught thats handy the only peoplewho need to read that cant lol . it did make me chuckle lol .

7 metres high by 6 metres wide, or so the books state, so you are going need a very large container! I would have thought three in a garden your size would be a little bit much.

sounds like it to me bamboo and the potswill haveto be very large .

Um NP I'm not Bamboo - lol :-) Mind you growing them in containers will also contain the growth but they will still get rather large.

thatswhat i thaught oops sorry moon x .

Yes, I thought that some creative pruning would definitely be necessary, not to mention big tubs--thank goodness for hand trucks and dollies! : )

and cranes and JCB`s lol .
