Crimson Sentry Maple, Large Trees

Acer platanoides Crimson Sentry: Bareroot Norway Maple Trees in Standard Sizes

Acer platanoides Crimson Sentry is an ornamental Norway Maple variety. Compared to wild Norway maples, it grows slowly, and has a narrow, upright, oval shaped canopy, suitable for a medium-sized garden. The bright red young leaves darken through plum-wines in the summer and then go out in a blaze of reds and oranges in autumn. Its tidy form also makes it a good choice for an avenue. It looks great in mixed woodland where its rich foliage adds contrast to the green backdrop of other trees.
We grow another ornamental Norway Maple variety, the variegated Acer drummondii.

They can reach a height of about 9-10 metres, which is half the size or less than the wild species.

Delivery season: Maple trees are delivered bareroot during late autumn and winter, approximately November-March inclusive.
Choosing a size: Small trees are cheaper, easier to handle and more forgiving of less than ideal aftercare, so they are best for a big planting project. If instant impact is your priority, or if you are only buying a few plants for use in a place where it is convenient to water them well in their first year, then you may as well use bigger ones. All our bareroot trees are measured by their height in centimetres above the ground (the roots aren't measured).

• Soil: Any with decent drainage, except very poor and dry
• Red young leaves turn plum-purple in summer

Growing Crimson Sentry Maples

This hardy and unfussy tree will grow in almost any soil apart from peat or shallow chalk, and it won't thrive on very poor, dry soil. It loves clay and although it won't grow in wet soil, it doesn't mind a bit of winter waterlogging or flooding. It is quite shade-tolerant and totally pollution resistant.
It is suitable for very exposed locations, but not on the coast.

Other plants generally don't grow under it due to the shade it casts and the dense root system.

If the tree is stressed, it is susceptible to powdery mildew. Raking up leaves and removing them in Autumn will help, as will a rich mulch in Spring if your soil is on the poor side. Trees in full sun are typically much less affected, unless the soil is too dry, so watering mature trees in a drought is worthwhile.
