Crimson Hawthorn CRATAEGUS CRIMSON CLOUDBritish Grown
CRATAEGUS CRIMSON CLOUD – Ornamental Hawthorn
Not every tree is as aptly named as this one! A cloud of crimson flowers with striking white centres adorns the tree in May providing a very colourful and appealing display. Only reaching 7m (23ft) with a rounded, gently arching canopy this hardy species makes an ideal garden tree. The stunning flowers are single and nectar-rich providing food for bees and other insects. Over the summer the flowers begin to form small red berries favoured by thrushes and other garden birds. The leaves are a typical hawthorn leaf shape; small with attractively cut edges.
Where to grow
Crimson Cloud would make a good specimen tree for the lawn or would work equally well as a feature in the border. It forms a good screen when in leaf and has a relatively dense framework of bare branches in the winter months. Hawthorns are tolerant of any soil and are hardy in exposed locations. Plenty of sunshine is best although they do grow in partial shade.
Did you know?
Willa Cather (1873 – 1976) was a novelist and poet born in Virginia, USA who wrote the poem ‘The Hawthorn Tree’. It is apt given the name of this tree ‘Crimson Cloud’ that she attended Red Cloud High School.
The Hawthorn Tree by Willa Cather
ACROSS the shimmering meadows--
Ah, when he came to me!
In the spring-time,
In the night-time,
In the starlight,
Beneath the hawthorn tree.
Up from the misty marsh-land--
Ah, when he climbed to me!
To my white bower,
To my sweet rest,
To my warm breast,
Beneath the hawthorn tree.
Ask of me what the birds sang,
High in the hawthorn tree;
What the breeze tells,
What the rose smells,
What the stars shine--
Not what he said to me!

Pruning Crataegus Crimson Cloud
Crataegus Crimson Cloud can be a very dense tree so you may find stems to be congested; simply remove these in winter, cutting back to an outward facing bud as this will limit congestion on regrowth. Crataegus can be pruned to maintain a certain size or form, one of the reasons they are ideal for hedging. To keep a neat outline, light prune in spring once flowering has finished.
What time of year should I prune? Prune in winter or after flowering.
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.
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:
- 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.
- 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.
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.
