Acer palmatum

B3B3 South East LondonPosts: 22,305

 I bought an acer palmatum today because it was cheap and will put it in a container for a while. This is not the problem.

I noticed on the label that it ultimately grows to 8mx8m!

The thing is, I had one that outgrew its container so I bunged it in a bed at the end of the patio on a live or die basis. It thrived and looks great.

My question is, do all acer palmatums grow to this size?  Mine's a green one. It'll be fine for a good few years yet, but should I be doing anything to stunt its growth?

    Hi B3. Japanese acers are relatively slow growing. I have grown acer palmatum from the seeds of my adult tree - which is now 20 years old and only about 3m high - and they live happily in pots. They are about 60cm high. If you keep the tree in a pot it should stay quite small for a long time. Its almost like growing them as a large bonsai.

    Hi B3.  The straight Acer palmatum, green or purple, does grow into an elegant tree eventually - quite wide spreading, and yes - maybe 8m when mature.  But the named cultivars are often a lot smaller, especially the cut-leaved ('dissectum') ones, which are good in a pot.  I'd always check a good website or book for eventual height rather than believing the label which comes with the plant (especially if it's from a Dutch nursery - their info labels tend to be generic rather than specific to the cultivar/variety you've bought).

    It was the one in the ground I wasa bit worried about. I assume in 20years time I will have other things or nothing to worry aboutimage

    Thanks ladybird

    And thanks liriodendron. It's not a cutleaf one but the leaves are quite small. Will see if I can find it on Google

    Aym, This is what I was wondering. It's got a good shape at the moment and the size is not a problem  - yet.

    I'm afraid mine is already in the ground. It's been there for a few years. It's  about 6ft wide  and 4ft high. It's not causing any problems at the moment. I foolishly assumed it was some kind of dwarf tree. Got a bit of a fright when I realised the ultimate dimensions

    A veritable forest, Aymimage Well done!

    I think I'll enjoy it until it becomes a nuisance and then  follow your advice although I don't really understand the jacket potato thing, I do understand hard pruning!

    Here it is. If you see any twiggy bits it's a glaucous rose that's losing the survival of the fittest contest but just about hanging in there.  I will have to get another as it is one of my favourite plants

    I agree aym. The one I bought yesterday will be kept under strict control. It was less than £3 and couldn't resist.
