Product Description



Acer palmatum, the Japanese maple, is a truly iconic small tree with fine leaves displaying the classic five-lobed shape, slightly serrated at the margins. Elegant in form at any time of year, it is particularly prized for its rich scarlet autumn colour.

A large number of cultivated varieties of Japanese maple are available with features such as finely dissected leaves or coloured stems. Acer palmatum, the species from which these are bred, is indeed a variable tree, but in general will grow slowly to about 8 metres with a broadly spreading, open crown. The foliage emerges bronze-tinged in spring and is mid-green in summer, before the striking autumn display. Small red flowers in spring are followed by winged seedcases.

Where to grow

Japanese maple prefers some shelter, but will grow on any moist but well-drained soil in sun or part-shade. Bright sunshine and dry conditions may cause some leaf scorch – ameliorate this by making sure the ground does not dry out in summer and choosing a sheltered planting position. Prefers a neutral to acid soil, but will tolerate any soil that isn’t very alkaline.

Native to Japan, Korea, Taiwan and eastern China, Acer palmatum was introduced to Britain in 1820.

Some dieback may occur in winter – simply prune this off in spring if it becomes noticeable. Otherwise little pruning is necessary except to control shape/growth, if needed. Protect leaves from late spring frost with fleece, if desired.

For the continued healthy growth of your trees, shrubs or hedging it is vital that you follow the advice below.


The main reason that plants die within 12 months of having been planted is lack of water. It is essential throughout the spring and summer, to give a heavy enough watering to enable the water to penetrate right down to the deepest root level of the tree. In hot dry spells give the equivalent of 2 bucketfuls every three days.

Weed Control

One of the most common causes of lack of water is competition from grass. When trees are first establishing, the grass roots would be at the same level as the tree roots and are far more efficient at taking up water and thus choke the tree. It is vital that for at least 3 years after planting your tree or hedge has a circle or strip one metre wide completely free of grass.

  1. Mulch mats are an effective way to stop grass and weeds, although they will require a careful eye to make sure they continue to work. After clearing the ground around the tree, firmly fit the mat by tucking the edges into the soil and put a thick layer of bark mulch on top of this. Be careful not to allow the woodchip to touch the stem as it can cause rot.
  2. Weed killer is very effective, however it is harmful to the environment. Organic weed killers usually do not kill roots. Weed killer needs to be applied each year for the first 3 years, preferably when the tree is dormant, or just once before applying a mulch mat.
  3. Mowing or strimming is NOT an answer to the problem. Each time you mow, the grass will grow back more vigorously and strimming invariably leads to lacerated trunks.


If trees are not correctly secured they will rock in the planting pit. Roots not firmly in contact with the soil are unable to take up moisture and nutrients, resulting in die back or death of the tree. Check, particularly after windy weather, that stakes are still solidly in the ground keeping the base of the trunk firm. The purpose of the stakes is to anchor the roots. Flexing in the wind, higher up the trunk, is not necessarily a problem if the roots are firm.

Bellow is list of the correct system to use to secure your trees.

  • 40/60, 60/80, 80/100 whips - Unless rabbit/deer problem no need to stake.
  • 100/125, 125/150 1.2m Cane and Easi tie.
  • 150/175 1.2m square stake and a buckle tie and spacer.
  • 175/250, 6/8, 8/10 15L 1.65 Tree stake and a buckle tie and spacer.
  • All larger trees. 2 x 1.65 Tree stake and cross rail with 38mm cushion spacer and 1m of 38mm strapping.


Always use our recommended tree ties or strapping. These are designed and manufactured with the correct amount of give to hold the tree firm without strangling it. They should be checked at the end of each growing season for adjustment as the trunk thickens. Non proprietary materials such as baler twine will cut into the bark and should not be used.

Protection from Animal Damage

Rabbits, deer, sheep, cattle and horses can all potentially damage trees. Ask us for advice on the most appropriate guards for your trees or hedge. Squirrels are also a terrible pest when trees get to about 20ft tall but there is no protection available.
