Acer Platanoides Crimson Sentry Standard Trees

Acer platanoides Crimson Sentry is an ornamental Norway Maple variety. It is much smaller than its parent, suitable for a fairly small garden, and it has plum-wine coloured leaves that burst into joyous reds and oranges in autumn. The Crimson Sentry Maple is a variety of Norway Maple with bright red young leaves that darken through the summer and then go out in a blaze of reds and oranges in autumn. Compared to wild Norway maples, it grows slowly and reaches less than half the height, with a narrow, upright, oval shaped canopy. Much better suited than its big cousin for a smaller garden. 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.

Acer Crimson Sentry trees can reach a height of about 9 metres. We also buy another ornamental Norway Maple variety - Acer drummondii.
You can also buy wild Norway Maple saplings and large Norway Maple Trees.

How Standard Trees are Measured:
All the plants in the ornamental trees section are graded as standards, which means that they are measured by their girth in centimetres 1 metre above ground level (basically, their trunk's waist measurement). They aren't measured by their height, which will vary. So, a 6/8 standard has a trunk with a circumference of 6-8 centimetres and an 8/10 standard has a trunk 8-10 centimetres around. This measurement makes no difference to the tree's final height.
Standard trees are 2 - 3.5 metres tall (on average) when they arrive; they are the most mature trees that you can buy from us. We cannot tell you precisely how tall your trees will be before we deliver them.

History & uses of Crimson Sentry Norway Maple

This tree was discovered as a sport of Acer platanoides Crimson King in Oregon, 1974.

Notes on planting Acer Crimson Sentry trees:
Crimson Sentry grows well in chalk and heavy clay, but it will thrive in most UK soils, as long as they are not very wet or too sandy. It tolerates shade well, but because it is naturally quite slow growing, we recommend at least half a day of sun.

Prepare your site before planting:
It is good to dig over the site where you plant a tree several months in advance. Kill the weeds first: for tough weeds like nettles, brambles and ground elder, you will usually need a glyphosate based weed-killer to get rid of them. When you dig the soil over, remove stones and other rubbish and mix in well rotted compost or manure down to the depth of about 2 spades.

Watch our video on how to plant a tree for full instructions.
Remember to water establishing trees during dry weather for at least a year after planting.

Tree Planting accessories:
Prepare your site for planting by killing the weeds and grass with Roundup weed killer.
You can buy a tree planting pack with a wooden stake & rubber tie to support the tree and a mulch mat with pegs to protect the soil around the base of your tree from weeds and drying out.
We suggest that you use mycorrhizal "friendly fungi" on the roots of all newly planted large trees: if your soil quality is poor, we strongly recommend it.
You can also improve your soil with bonemeal organic fertiliser and Growmore.

After you plant a tree, the most important thing to do is water it in dry weather. You will also need to weed around the plants. Watering should be thorough, so the ground is soaked. Let the soil almost dry out before watering again. Watering & weeding will be necessary for at least a year after planting.

If your trees do need pruning, it is best to do this in mid-summer, unlike most deciduous trees. Acer species will bleed sap quite heavily if they are pruned at other times of the year, which makes it harder for them to heal. Always hire a tree surgeon to remove large branches.

Special notes on caring for Acer Crimson Sentry trees:
Acer Crimson Sentry is a very tough tree that shouldn't need special attention once it has established.
Remember to check the stake and tie supporting your trees a few times a year. Tighten the tie if it becomes loose and loosen it as the tree grows. Make sure that the tree's trunk isn't rubbing against the stake.

Hygiene & Diseases:
Dead, damaged or diseased wood can be pruned off as soon as it appears.
Disinfect your pruning tools between every cut if there is any sign of disease.
Burn or dispose of any diseased material, do not compost it.

Pallets (Root balls, large pots, trees etc) £60.00 including VAT per order (FREE For ORDERS Over £240 inc VAT)

Because couriers sometimes experience delays, we schedule delivery by week, not by day. Therefore, please plan your planting day for the weekend at the end of the delivery week or for the week following delivery, at the earliest.
We will email you the day before your plants are due to arrive.

*Surcharges to the Highlands and Islands still apply.

Payment: We do not charge your card until we begin to prepare your order for packing.

Guarantee: If any plants die within a year, we will replace them. We only ask that you follow our planting & growing instructions and sent us clear photographs of the dead plants in situ, so we can help to make sure that the replacement plants succeed. You only pay for the delivery of the replacements.

Please note that our guarantee is void if there is a hosepipe ban in your area: your newly planted hedging must be watered in dry weather while it is establishing. The best way to water is very thoroughly every few days: at least once a week if there is no heavy rain.

Our nursery has been supplying container grown and bareroot hedging plants to gardeners, farmers and town planners since 1949. Our website started in 2003, so we do understand the concerns that you may have about buying hedging plants online. If any of your plants are damaged when they arrive or if you are otherwise not satisfied with your order after you inspect it, please repackage it and contact us. We will give you a refund or send replacements and send a courier to come and collect the unwanted plants.
