Hello,

I have a few trees in my yard, oaks and pines, that have english ivy
climbing up the trunks.
Is this OK for the trees?

Thanks in advance,
Vin

Ivy will do no damage, but many find it unsightly. It takes nothing
from the tree~~ only support. It can hide disease but also provides nesting
sites. Take your choice!!

As the ivy grows into the tree it blocks out the sunlight off of the
bark, which in turn keeps the activation of dormant buds from happening
along with the development of new buds which produce new leaves, which
produces photosynthesis...

Here's my article "About Ivy Climbing Trees":
http://www.paghat.com/ivyclimbs.html
The short answer is it is harmless with very few exceptions. Certainly
covering the bark has no effect whatsoever on photosynthesis & buds are
fed from the roots not from the sun. If ivy could cover the a tree to the
dripline hiding the leaves that'd be a problem, but it is not inclined to
do that. There are a couple reasons to not keep such ivy, addressed in the
"climbing trees" article, the main one being that ivy increases wind
resistance & increases blow-down of shallowly rooted trees.

There's also the issue of "invasive vs non-invasive ivy" covered he
http://www.paghat.com/ivy.html
Frequently what people have is just nasty, nasty ivy that harms the
environment (unless you live where it is truly native & its a proper part
of an ecosystem adapted to it). It poisons birds & seeds into nearby
woodlands displacing native plantlife. If this is the one climbing the
trees:
http://www.paghat.com/hederahibernica.html
then just get rid of it &amp replace it with non-invasive cultivars, which
tend to be prettier anyway with great variety.

In the Washington, D.C. area, the National Park Service sponsors work days
several times a year to remove English Ivy from National Parks as they
consider it invasive and damaging to trees.

No, latent buds are stimulated by sunlight. If the ivy is on the
trunk--no biggie. Once it starts creeping out on the branches, you
get the same effect as "lion-tail" pruning: lots of long, narrow
branches with a few leaves at the ends, which break easily, and which
have no interior branches to preserve when they do break.

And, as was mentioned, it can provide camouflage for decay/disease and
creates a nice, moist microclimate that might harbor spores, insects,
or other bad stuff.

Also, some ivy tends to wrap around branches and create a "noose,"
strangling the branch beyond it.

If you maintain the ivy so it doesn't creep into the upper canopy, you
could keep it without much trouble (probably), but the most
tree-friendly approach would be to get it out and keep it out.

a lot of time with my x-ray specs on trying to see through the ivy on
many trees in high occupancy target areas!

In the grand scheme of things, yes. In relation to a specific tree,
not necessarily.
