Product description

ILEX X NELLIE R STEVENS

Characteristics

This evergreen holly with its handsome glossy leaves has been a popular in America for decades and is now becoming more popular in the UK for its vigorous growth and compact habit
It grows in a neat pyramidal shape to about 6m (20ft) in height. Ilex Nellie R Stevens is a hybrid between English holly (I. aquifolium) and Chinese holly (I. cornuta).
The leaves are thick and have teeth typically associated with the holly. This female holly is extremely fruitful and colourful when loaded with bright red berries in winter. It provides both food and nesting habitat for birds.

Where to grow

Hollies will grow in most well drained moist soils with good levels of organic matter and nutrients.  They do not tolerate waterlogged ground particularly well and will do better if sheltered when small.

Did you know?


Ilex x Nellie R. Stevens was developed in Maryland and released to the nursery trade in 1954, it is quite popular in the southern United States as it is fairly heat and drought tolerant.

Aftercare

Pruning Ilex Nellie R Stevens

Ilex Nellie R Stevens will naturally form a conical shape, however, vigorous shoots can make the outline untidy so ideally clip each summer. Pruning will affect the abundance of berries.

Training as a standard with a central clear stem is possible. The number of years this will take will depend on the height of clear stem desired. Each year remove the lowest lateral stems, as well as any vigorous shoots that pose as a competing leader

What time of year should I prune? Pruning is best done in summer

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.
