Acer Platanoides Crimson Sentry Norway Maple
Gardeners with smaller spaces will appreciate this tree due to its mostly upright shape and stunning foliage colour. Some sources have described it as proudly standing to attention and guarding your garden so if you enter your garden on a dark night and a tree like voice demands the password, you know this to be true.
With a height and spread of 6 x 2 metres at 10 years, the Acer Crimson Sentry is attractive and slender. The smaller footprint leaves more room for cartwheels and doing the Tango if you are that way inclined. It could go on to grow more and possibly get to 12 x 5 metres but this depends on local conditions. The first height is the adolescent height which all trees are expected to achieve. Once there, they could carry on growing or just stop.
Expect yellow flowers with red tinges in the Spring before the leaves make a grand appearance. They may feel a little sticky to the touch and this is not a vengeful neighbour going mad with a tin of syrup, just Mother Nature doing her thing.
If you have ever told your partner that you have had more passionate kisses from zoo monkeys behind glass then you will have already seen the facial shades of red and purple the Crimson Sentry will exhibit during Spring and Summer.
Suitable for any location where you want to make a statement such as parks and ornamental gardens but not on a soap box outside Parliament. Coastal positions and pollution should not be a problem making it a fantastic Acer to plant almost anywhere.
Acer Crimson Sentry is supplied at a height of 150cm -250cm in a 5 -20L container, which means that the tree has an already established root system and therefore this tree can be planted any time of the year. Expect a growth rate of around 30-45cm per year.
The options usually available are:
150-200cm : These are usually 2-3 years old and will be 150-200cm tall depending on weather and time of year purchased. Pruned to be Half Standard.
200-250cm : These are usually 2-3 years old and will be 200-250cm tall depending on weather and time of year purchased. Pruned to be Half Standard.
If the options available are less than those explained above then we are out of stock of that item.

Planting Acer Crimson Sentry
Plant in a full sun or partial shade position in fertile and well draining soil in a location that doesn't get below minus 15 degrees centigrade.
Remove any competing weeds and other plants within 100cm of your Acer Crimson Sentry planting spot. Dig a hole as deep as your pot but break up the bottom 5-10 cm to allow the roots to spread a little easier. The purists will tell you to make the hole square to reduce the chances of the roots spiralling round, this is your choice. Make the hole wider than the pot, this is to follow the same principle as breaking up the bottom. You can mix in some ericaceous compost to promote enhanced foliage colour with the returning soil. Try and plant so the top of the rootball soil is level with the garden soil as you need to avoid bark that was previously exposed to air being buried. If you go slightly deeper, you can always make it slightly "dished" by having the outer edges higher than the middle.
Water well after planting, at least 20 litres spread around the whole root system. If planting in Summer, especially long hot ones, regular watering will be important. If the soil is dry for the top 10cm or so, it will be time to water. If you have used ericaceous compost as a soil improver then rain water will be preferable to tap water to maintain the PH levels.
Keeping nearby weeds down for the first few seasons will help the young Crimson Sentry and this can be achieved with manual removal, mulching, decorative stones, agricultural matting or glyphosate (weed killer).
Pruning Acer Crimson Sentry
It is likely that the Crimson Sentry you purchase will have been pruned at an early age before you receive it. This is to promote branching, not to remove any previous damage or to make it smaller to get in the box.
Pruning for this tree should be within the dormant season which is November to March. This is because the tree bleeds and can lead to negative issues. It is always best to prune when you are expecting a few days of dry weather as this aids in the pruning cut healing and reducing the ingress of infection. You should always cut out dead, diseased or crossed over branches but other than that, Crimson Sentry can be pretty much left alone as its natural shape is very ornamental.

Ornamental Tree Roots In The Shade e.g. Behind A Fence
It is more important that that foliage (posh term for leaves) receives the sunlight than the roots. So if the canopy of your ornamental tree can sunbathe but the bottom of your tree thinks there has been a nuclear winter then that is ok. You might want to ensure you have good drainage as water and no sun is the start of algae and other such issues.
Early Autumn Leaf Fall
Heat stress, being potted, lack of water, being boxed up for a few days etc can cause early Autumn leaf fall. Once planted, normal service will resume next season.
Do I Need To Stake My Ornamental Tree?
9 out of 10 times the answer will be no, especially if under 200cm tall. However our article on Tree Staking should help guide you.
UK Grown Ornamental TreesClimate Change
All our trees are banned from overseas travel so that we can state they are all UK grown. We have removed Internet access from the nursery so they cannot book any flights.
Warm and wet conditions from Climate Change have increased aesthetic foliage issues such as Powdery Mildew, Shothole, Rust etc These are not terminal issues and will usually last a season. All trees are inspected before being sent out to ensure they are fundamentally healthy. Planting In The Corner Of A GardenAir and light is reduced in this location which could promote fungus and bacterial issues. If the corner is of the house and a fence then you also have leeching issues to contend with from cement and wood preservatives. Also when it rains, that area would experience higher water levels so we advise against it unless the plant is very hardy.
