Acer platanoides 'Crimson King'
- Position: full sun or partial shade
- Soil: fertile, moist, well-drained
- Rate of growth: vigorous
- Flowering period: April to May
- Flower colour: yellow
- Other features: beetroot-red leaves turning red, brown and orange in autumn
- Hardiness: fully hardy
Dark beetroot-red leaves turning red, brown and orange in autumn and small clusters of red-tinged, yellow spring flowers. This handsome, large, round- headed tree makes a fabulous ornamental feature for a large garden. Fast-growing and pollution-tolerant it thrives on almost any soil, including clay. Valuable for screening unsightly buildings.
- Garden care: Add a top-dressing of a multi-purpose fertiliser around the base of the plant in late spring. No routine pruning is required, just remove any dead, damaged or crossing branches in late autumn or winter when they are fully dormant.

Q:I planted an Acer Palmtium Seiryu about 4-5 years ago thinking it would be slow growing and not too high. It currently stands at around 6ft. and I realise now it is in the wrong location. Can I transplant it to another position in the garden approximately 12 ft. away without the risk of loosing it? I was planning on doing this in September.
I look forward to hearing from you.

If this plant has put on lots of growth, then I suspect moving it will be be pretty risky as the rootball will also have gotten quite large. If however it is in the wrong place and it has to go, then it is worth giving it a go. I would wait until it is completely dormant (I think September will be too early) and then dig up as much of the rootball as possible. Move it to its new home immediately and keep it well watered. You are unlikely to know how successful the move has been however until the following spring when (hopefully) new growth will start to emerge.Answered on 31/5/2016 by Helen from crocus
Q:How can we stop Powdery Mildew on our Norway Maple tree?
Hi. We purchased a Norway Maple tree around 3 years ago from Crocus, and every year towards the end of the Summer, the leaves have a powdery white mildew on them. We do have clay soil, but try to keep the tree well watered in dry weather. We have also tried a mildew spray, this seems to prevent any further mildew from appearing at the time. Do you have any suggestions as to how we can stop it appearing this year? Many thanks for your time. FionaAsked on 15/2/2010 by Anonymous
A:Hello Fiona, Powdery Mildew is caused by poor air circulation around the branches and dry soil around the roots. We do have a page on our site which you may find useful so just click on the following link to go straight to it. http://www.crocus.co.uk/pestsanddiseases/_//top12/Powdery%20mildew/ArticleID.1174 I hope this helps.

Q:Fungus and dry leaves on Acer?
Hi there, I have noticed in the last week that one of my Acers has developed very dry yellowed leaves and a white soft fungus on its bark, what do you think this could be? My other Acers are fine, but I'm worried that this will spread. What can I do to remove/avoid this? Kind regardsAsked on 14/9/2009 by nikki craig
A:Hello There, Acers are prone to a number of pests and diseases, but I suspect yours is suffering from a wooly scale - just click on the following link for more information. http://www.crocus.co.uk/pestsanddiseases/_/pests-and-diseases/stems/artcat.6/ I hope this helps.

Q:What tree for a ruby wedding?
Evening, I am looking to buy a tree (or two?) for my parents as a ruby wedding anniversary present, so ideally looking at something that is red oriented. Any ideas? Regards IanAsked on 1/7/2009 by Goode, Ian
A:Hello Ian, There are some cracking trees which would be suitable - I would opt for one of these - Acer palmatum var. dissectum 'Inaba-shidare', Acer palmatum 'Atropurpureum', Acer platanoides 'Crimson King' or Malus 'Royalty'Answered on 4/7/2009 by Crocus Helpdesk
Q:Which Acer platanoides should I buy?
Please could you tell me which is the most attractive tree of the red coloured Acer platanoides ie 'Crimson Sentry', 'Royal Red', 'Crimson King' or other. Thankyou. CarolineAsked on 18/6/2009 by Holmdale Exmoor
A:Hello Caroline, They all have attractive foliage, so the distinguishing feature between them will be their size and shape. 'Crimson Sentry' is tall and thin and has an eventual height and spread of 12 x 5m, while 'Crimson King' is a much bigger tree with a wider canopy growing to 25 x 15m. I hope this helps.

Q:Is there an evergreen Acer?
Could I just ask if there is an Acer that is not 'deciduous' but 'evergreen'?Asked on 14/3/2005 by Susan McGarragh
A:Sadly not as all Acers are deciduous.Answered on 16/3/2005 by Crocus
By November the garden is well and truly dormant, so it’s a good time to prune many deciduous garden trees. As for October, prune newly planted trees to remove any damaged growth and help balance the shape of the canopy as well as maintain a dominant mainRead full article
The garden is at its most dormant right now, so it’s a good time to catch up on any pruning missed or forgotten since the autumn. If the weather isn’t favourable, you can leave it for a week or two, but make sure all winter pruning is completed before theRead full article
