Product description

Characteristics

Sculptural, cascading branches and finely dissected, colorful leaves make this classic selection one of the finest of the deep red laceleafs. Foliage emerges bright crimson, deepens to burgundy in summer and finishes with brilliant scarlet in autumn, maintaining its colour, despite summer heat and humidity. The elegant, mounding plant produces a dense, broadly spreading structure that makes a dramatic impact near water, on a bank or in a courtyard.

Where to grow

Some care is needed in the siting preparation of all Japanese maples.  They are not the easiest of trees to establish, needing care in planting and protection from the elements until they have formed established root systems.  They do not like wet or heavy soils neither will they tolerate poor dry soils. They will only grow well in moist well drained humus rich soils.  Therefore pre planting ground preparation is more important than ever, watering while in leaf need to be like the goldilocks story, not too little, not too much, but just right.

They almost all need some shelter from strong winds which will scorch the leaf ends.  Small plants are particularly susceptible and will need nursing until they have a strong branched structure.

Aftercare

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

Watering

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 for 3 years after planting that your tree or hedge has a circle or strip one  metre wide completely free of grass.  The way to eliminate grass in order of effectiveness is:

  1. Spray off the grass with a glyphosate based weed killer such as Roundup.  Apply each year for the first 3 years.  It is best applied when the tree is dormant as it is absorbed through green leaves and kills the plant off at the roots.
  2. Firmly fit a mulch mat around the base of the tree by tucking the edges into the soil and put a thick layer of bark mulch on top of this.  This can be done after the initial spraying with glyphosate and should avoid the need for further spraying.

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.

Staking

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.

Ties

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.

I have had an Acer palmatum dissectum Crimson Queen for about 12 years and it has grown into an incredible beauty being in full leaf at the same time as a flowering cherry tree next to it.  Last year it did not get its leaves until almost two months after the cherry flowered and was nothing like the magnificent specimen it had been.  I feared it was dead to start with.  This year the same problem has occurred.  The cherry is flowering, and I can see that there are small shoots appearing but again it is going to be another two months before it is in full leaf.  Has anyone had a similar experience or can anyone offer advice on how to return this shrub to its former glory.

Hello Jean,

It’s difficult to say for sure why your Acer Crimson Queen is coming into leaf later than in previous years, but it could be due to weather conditions such as late frosts. I wonder whether this is the cause?
