Hedera Helix

Please can anyone help me. Why do certain Ivy's only grow on certain trees? I have noticed where I live that the Common Ivy (Hedera helix) is only growing on the Small Leaved Lime (Tilia cordata) and the Common Ash (Fraxinus excelsior)? Can anyone shed any light?

Good question!

As far as I know, ivy forms no organic link with the supporting tree. It attaches by means of adhesive pads, but they are not invasive. This is why it can grow on walls.
As a result, ivy shouldn't have a species preference.
It is possible that the plants form an association with fungi in the soil: in which case the fungal species will largely be related to the trees nearby. So maybe there is some preference there.

Fungi in soil

That is something I will have a look at when we thaw out. Many thanks I will keep you posted. It was just very noticeable.

It is certainly worth investigating further -

For all we know, you may have hit upon something interesting that has gone unnoticed!
