Buy Acer platanoides 'Crimson Sentry' Norway maple: Interesting tree due to its habit

This tree is deciduous so it will lose all its leaves in autumn, then fresh new foliage appears again each spring.

  • Position: full sun or partial shade
  • Soil: fertile, moist, well-drained
  • Rate of growth: vigorous
  • Flowering period: April to May
  • Hardiness: fully hardy

    Because of its narrowly upright habit, this handsome Norway maple will make an excellent specimen tree for a medium-sized garden. Covered in crimson coloured leaves throughout the summer, these turn shades of red, brown and orange in the autumn before they are shed. A robust plant, it's tolerant of pollution and will thrive on almost any soil.

  • 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.

This tree needs careful attention to avoid powdery mildew. Water regularly in first year, and ongoing be aware that the soil is kept moist & doesn't dry out. Try spraying with pure diluted seaweed on leaves to support the tree's defence against powdery mildew. Remove the fallen leaves from the ground in the autumn.

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. Fiona

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.

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 regards

Acer platanoides 'Crimson Sentry' leaf problem? Hi, I purchased an Acer plat. 'Crimson Sentry' tree last year. It has been splendid all summer with lots of new growth, a lovely rich red. Now, however some of the leaves have a white powdery covering on the upperside of the leaves. Can you advise what is causing this. The leaves will be falling shortly so will next years leaves go the same. Thanks Maureen

Leaf problem on new tree-will it spread to other trees? Hi, I purchased two Acer plat. 'Crimson Sentry' trees in April of this year and have noticed a white powdery substance has taken hold on the leaves of both trees. Initially I thought it would go away but it has spread to almost every leaf on both trees. Please can you offer any help on what this is and how I can get rid of it. Also, is it likely to affect the other two trees I purchased at the same time (Laburnum ?? watereri 'Vossii' and Robinia pseudoacacia 'Frisia'). Many thanks Amanda

Amanda Button

Hello Amanda, Acer plat. 'Crimson Sentry' trees are prone to powdery mildew, which would fit your description - just click on the following link for more information. http://www.crocus.co.uk/pestsanddiseases/_//top12/Powdery%20mildew/ArticleID.1174 The Robinia is unlikely to be affected by it, but the Laburnum is also prone occasionally. I hope this helps. Helen Plant Doctor

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. Caroline

Holmdale Exmoor

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.

Is there an evergreen Acer? Could I just ask if there is an Acer that is not 'deciduous' but 'evergreen'?

Susan McGarragh

Sadly not as all Acers are deciduous.

Autumn Colour

Perhaps it is because the colours of autumn are so variable in the UK that we value them all the more when they appear. As levels of sunlight fall in autumn and the days become shorter, photosynthesis is no longer effective. For the tree, leaves tha
