Entrenched Ivy on Mature ASH removal

I decided to reclaim the garden but the hedge was so heavily entwined with ivy I found it had killed two hawthorns by smothering them completely. I now have large bare areas in the hedge which I am trying to layer hawthorn from adjacent plants into

 

ivy in a deciduous hedge, or a mixed hedge is a nuisance, the evergreen part of a mixed hedge can cope, but the deciduous part gets shaded out by ivy, made worse by any top growth from the hawthorns etc getting removed with a hedgetrimmer.

Quite a few ivy hedges about now that were once something decent. 

 

Leaving the ivy on that ash tree is like seeing an elderly person being mugged in the street and crossing to the other side to avoid getting involved - the tree is being mugged of daylight. Just don't cut into the trunk

Do you know that to be a fact, or is it an assumption based on the premis that ivy is bad and you can see it, whereas you can't see what actually might have killed the thorn.

 

I cannot be certain of cause but can see the effect. The fact that the remainder of the hawthorn hedge is fine, even though areas have died out on individual plants where the ivy was, prior to being severed, and that the part where the two plants died was completely inundated with ivy...

 

As I said I never had the notion ivy was particularly bad, apart from making trees difficult to inspect and increasing the wintertime sail area, I valued it for the habitat it offered as well as its looks.

 

Cattle love it too.

Edward, ivy is bad.

It would take a baby from a cot.

 

Of course it will infest shitbag trees, but it will also infest healthy ones given a chance.

Left unchecked there is no doubt it doesn’t help the tree at all.

There are plenty of trees I regularly strip away ivy growth above the crown break but leave on the stem.

As you say, it’s cracking habitat.

SRT for the win!

You are looking at a different tree to me. The leaves are found towards the outside of the crown which isn't covered in ivy so how is it 'mugging' it of light.

Go and climb a few mature ash not covered in ivy (if you can still manage it) you will see that although most foliage is near the tips, there will be side branches with growth inside the crown too. It is these that are shaded by ivy and die off. And you know it full well! Just look at that big side branch in the photo - I've seen similar ivy clad limbs completely die and break off (alder). The limb can't be maintained just by a few leaves right at the end, the ivy has covered what would have been healthy shoots, as it keeps going in winter after abscission of the tree leaves.

You can lead a horse to water, but you can't make it drink.

based on ignorance, (e.g ivy kills trees),

I have never seen a tree looking happy to be covered in Ivy.

Sure, Ivy is not parasitic, but it doesn't exactly sit benignly in the tree doing nothing. It grows ruthlessly, adds weight and wind drag, and deprives leaves within the crown of light.

Does this help?

 

Particularly this bit: 

When to consider controlling ivy

• If the branch canopy becomes thin and allows sufficient light to enter, the ivy will develop into its arboreal form. Fraxinus (ash) and Larix (larch), are both trees with a naturally thin, open crown so may suffer heavy infestation. For this reason ivy on ash and larch trees is often controlled

Murderer!

[tree-fancier123]

murdering is ok, as long as you think it through first

[Mark Bolam]

Sounds like a good job.

 

Love the ‘deliberately’ caveat!

Churchill called it arboricide when they felled some box from Chequers (IIRC to make draughstman's rulers)
