Product description
HAMAMELIS X INTERMEDIA ARNOLD PROMISE
Characteristics
Is a cultivar of the hybrid Hamamelis x intermedia (a cross between H. mollis and H. japonica). It is a wide growing shrub covered in large, orange-pink to ochre-yellow flowers in January-February. The petals are dark red at the base. The leaves turn beautiful red in autumn.
The first specimens of this cross were created in the 1930’s in the Arnold Arboretum in America and at Kalmthout in Belgium. They are stout wide shrubs or small trees. In comparison to the species, these cultivars have larger flowers and turn colour more beautifully in autumn.
Where to grow
Witch hazels need free-draining soil conditions with an adequate supply of moisture. A light soil with plenty of added organic matter, such as well-rotted manure or compost, is best. They will tolerate heavy or clay soils if they are improved by digging in organic matter and by ensuring good drainage. An open, sunny position is best, as they can become straggly in shade, although they do tolerate partial shade. Avoid exposed and windy positions.
Did you know?
Arnold Promise is a selection from the typical plants of H x intermedia raised at the Arnold Arboretum part of Harvard University in and named in 1963. The original plant is still in the Arboretum.

Aftercare
Pruning Hamamelis X Intermedia Arnold Promise
Hamamelis x intermedia Arnold Promise is spreading multi-stemmed tree. Aside from maintenance pruning, little pruning is necessary and the tree is best left develop in its natural form. It is prone to suckering, and these are best pruned at the base as soon as they are spotted. Unproductive new growth should be cut back to older healthy stems.
What time of year should I prune? Prune straight after flowering in the spring.
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:
- 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.
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.

Could I grow witch hazel Arnolds promise against a fence as a basic fan trained shru, or is it too bushy?b

Hello Heather,
As long as you start with a small plant where the growth is still flexible, you can train it.
