A beautiful feature tree, this Purple Norway Maple has dark crimson foliage which covers the upright branches. This columnar tree is ideal for small gardens as it will grow to just 6 x 2 metres in 20 years. This ornamental tree is not only popular for its narrow form, but also the beautiful foliage which turns from dark-red to purple in the summer and then to red again in the autumn. Acer Crimson Sentry truly lives up to its name, standing proudly and boldly upright, as if guarding the surrounding area.

This Norway maple tree would make a lovely feature at an entrance or gateway. Ideal for tough positions, Acer platanoides Crimson Sentry is tolerant of pollution and will do well in most soils. Exposed coastal positions are no problem for this handsome small to medium sized tree.

Delivery timescales

99% of deliveries made within a week of placing the order (other than agreed pre orders) and many are despatched on the day we receive the order.  There is a slightly longer delivery timescale on trees over 2.5m in height (all the trees called Standard, Premium Standard, Heavy Standard or Extra Heavy Standard, all called Mature Trees) because normal "next day" carriers find them too large to handle so we have to group orders together into geographic areas for a haulage contractor to deliver and this all takes a bit of scheduling (but it's worth it when you see these wonderful mature trees!). 

Gift trees required for arrival on a specific date (or indeed any tree required for delivery on a specific date) can be accommodated with pleasure and at no extra charge - we normally plan to deliver a day or two before the special day just to be on the safe side and although we really don't like to give ourselves wriggle room (because we so rarely need it!), we do have to say that we accept no legal responsibility for late deliveries.

Bare root trees and fruit bushes can only be dispatched from mid-November - mid April/late April (depending on weather conditions) and whilst they are dormant.

The vast majority of trees are sent on a 'no signature required' basis, so there's no need to be in to receive your order unless we contact you (normally just the most mature trees where the driver may need help getting the tree/trees off the vehicle).  You can give us instructions on where to leave your delivery either via the checkout or send us a separate email.

Trees are packed very carefully by our experienced team and delivered using couriers who've been tried and tested over many years.

Our nursery is a busy despatch centre and therefore customers need to make an appointment to collect or view trees.  For collections despatch charges will be refunded.

Delivery costs

Orders for our popular range of 1.5/2.0m height trees to UK mainland ex Highlands have a delivery charge of £9.95 plus vat (Highlands charge will be applied in the check out).  Smaller trees/bushes are charged at £6.95 plus vat (again Highlands charge applied in the check out).  On orders for several trees, delivery costs increase to £12.95 (and honestly that doesn't nearly cover what it costs us in cardboard and carriage charges!) but you can buy several trees (or hundreds of trees if you wish) for the same delivery cost.  Highlands charges start to get a bit expensive if you require several trees which our customers in the Highlands will be well aware of - we wish we could help more but you're such a long way from Yorkshire!

Mature trees are more expensive to deliver and cost varies by postcode but again you can buy more than one tree for the same delivery cost so if you do need 2 or more, and particularly if you are planting a good number of trees, it works out to be really economical.  Delivery costs are calculated automatically in the shopping trolley so try adding an extra tree or bush for no extra delivery charge.

Northern Ireland, Channel Islands and overseas destinations

Our courier charges are not viable for just one or two trees but if you have a larger requirement please do speak to us and we'll do what we can to get trees to you at a reasonable cost.

Planting Advice for Acer Platanoides Crimson Sentry trees

When planting Purple Norway Maple trees, such as the Acer Platanoides Crimson Sentry tree, it is important to prepare the planting area well. Pot grown Norway maple trees can be planted at any time of the year. You will need to carry out the following to prepare your planting site.

Firstly, remove all weeds and grass within a metre of your desired planting hole then dig a hole as deep as your root mass and approximately 2x as wide. We recommend digging a square hole as this encourages the roots to grow straight as opposed to around inside the hole. To help your tree establish more effectively, we advise applying root grow (sprinkle in the hole for pot grown trees), especially if you have poor soil.

You do not need to amend the soil with compost when planting a Norway maple tree, simply fill in the hole and firm around gently. Make sure not to bank the soil up around the collar of the tree as this can cause problems. When planting Norway maple trees, you should use ericaceous compost when possible as this encourages vibrant foliage colour. To see how to use a tree stake and tie, watch our informational how to videos.

Aftercare Advice for Acer Platanoides Crimson Sentry trees

If you’re planting in dry weather, water well and regularly for the first few months. The same goes for spring and summer planting. Make sure to keep an eye on your young tree and increase watering if there are extended periods of hot or dry weather. If you’re planting in autumn, you may only need to water your tree a little. If possible, use rain water instead of tap water as this is more acidic and better for foliage colour. We also stock a range of irrigation kits, suitable for a variety of planting schemes.

Once planted, it is important to keep the area free of competing weeds for the first couple of growing seasons. Using a glyphosate based weed killer or installing mulch matting and bark chips will aid in this. Only shade loving plants will grow beneath Norway maple trees. If you wish to cover the area, decorative bark is the best option. If you know your area is prone to rabbits, we would advise using a rabbit guard.

Pruning Advice for Purple Norway Maple trees

Pruning should be carried out in the dormant season, from November to March. Norway Maple trees bleed during other times of the year so pruning can weaken the tree. However, Norway Maple trees very rarely need pruning. The natural shape is normally the most attractive and pruning should be carried out with a less is more approach. Only remove, crossing, damaged or diseased branches.
