Armstrong Maple Trees - Large Standards - Delivered by Mail Order from the Nursery with a 1 Year Guarantee
The Armstrong Maple tree, Acer x freemanii Armstrong, is slender and upright, similar to Acer freemanii Celebration, with brilliant gold and orange leaves in the autumn. It grows well on most soils (including chalky ones), but it gives the best autumn colour on soils that are neutral or acidic.
Armstrong Maple trees can reach a height of about 20 metres.

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.
General description of Armstrong Maple trees:
With its narrow canopy, this is an ideal tree for a fairly small garden or roadside. Older trees will spread out a little, becoming egg shaped, but this can be corrected with some gentle pruning. The autumn colour is simply awesome.
History & uses of Acer freemanii Armstrong
The Freeman maples, Acer x freemanii, are naturally occurring crosses between Red Maple and Silver Maple. They were first classified by Oliver Freeman in 1933 at the US National Arboretum in Washington DC.
Notes on planting Armstrong Maple trees:
Armstrong Maple trees will grow well in any fertile soil. They like heavy clay and although they are also happy on chalk, alkaline soils will reduce the quality of their autumn colour.
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 Armstrong Maple trees:
Armstrong Maple 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.
Sensitive to glyphosate weedkiller: Be careful not to get any Glyphosate based weedkiller onto this tree.
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.

Delivery: Any order with a standard sized tree in it has a basic delivery charge of £12.55 + 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.
You can choose the delivery week that suits you during checkout and we will email you the day before your plants are due to arrive.
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 trees must be watered in dry weather while they are 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 large ornamental trees to gardeners since 1949. Our website started in 2003, so we do understand the concerns that you may have about buying specimen trees 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.
