Hello gardeners,

I'm thinking about putting up a Boston ivy on the east side of our
house. That part of the house has wood siding. What do I need to get
Boston ivy to climb on it?

Thank you,

Ivy needs very little grip. You may need to 'tack' a few tentrils onto
the wall when you first plant it, but it will 'catch' fairly quickly.
You could tie it up with a few nails. It developes suckers on the
stems where it connects to anything.

BUT, ivy can be very invasive and destructive. You can train it to
climb up, but it will want to spread on the ground, so you'll want to
keep an eye on that. Once it is rooted, it is very difficult to remove
- take my word. Also, watch that it doesn't grow in between your wood
slats or other openings in the wood. Eventually it will pull the wood
apart.

It will look pretty covering your wall, just keep an eye on it. Good
Luck, Laura

I would not put Boston Ivy on wood siding. It will definitely grow under
clapboards and between the narrowest edges of trim and force the clapboards
away from the house. It also causes moisture retention which can lead to
potential rot, especially when the clapboards get a gap between them.

Wow! That's good to know.

So let's try this another way.

If I put up a trellis, and grow Boston ivy on it, how far from the
house should it be, to prevent it from reaching over and growing onto
the walls?

Or, is there a colorful climber that won't harm wood siding?

Or, can I safely have Boston ivy climbing a tree?

I'm just looking for options here.

Thanks for all replies.

Keep the Boston Ivy for a ground cover away from wood houses. You can let it
grow up solid concrete. Even Boston Ivy growing on bricks or cinder blocks
can penetrate the mortar joints. Something colorful and safer for a trellis
attached to the house would be clematis. One difference is that it won't
climb as high as ivy and is probably a little higher maintenance (just
because ivy is almost zero maintenance in terms of fertilizer,
winterization, insects, etc).

I'm sorry, but most of the replies in this thread are totally insane.

First of all, Boston ivy (Parthenocissus tricuspidata) is not a true
ivy (genus Hedera). It is a woody, deciduous vine, closely related to
Virginia creeper (Parthenocissus quinquefolia).

The reason it's called "Boston ivy" is that is grows all over the place
in the northeastern U.S., including on very old buildings that have
quite happily endured for centuries. It is the eponymous "ivy" of the
Ivy League.

P. tricuspidata will not, as some posters claim, sink roots into your
walls. What happens is, as the stems grow longer, they produce tendrils
that are tipped by small, disk-shaped suckers that stick like glue to
just about anything they touch. This is not a destructive process.
The stickers do not burrow or "root" -- they just stick, tenaciously.

This is worth thinking about. Once a Parthenocissus gets attached to
your house, it will want to stay there. But most of the fears people
express about this are clearly irrational, as a casual drive through
old neighborhoods in Boston or environs will attest.

I suppose you could think of more finicky alternatives, like ornamental
grape (Vitus) that could clamber up a trellis, or wisteria, which won't
hurt your wall but will need extremely sturdy support as it grows more
massive, or hops (Humulus), which you can get in a lovely golden-leaved
cultivar, and bugs absolutely adore, or climbing hydrangea -- which
actually I greatly admire, but is very slow to get established, and has
much of the tenaciously clinging nature of Parthenocissus -- and yes,
there is clematis, especially the small-flowered, autumn-flowering
kind. But there is no real substitute for the vigorous and carefree
and bird-friendly and tolerant-of-everything Parthenocissus clan.

For that matter, I don't believe many of the scare stories about real
ivy, or Hedera, either. Where I was raised, in Virginia, one can find
ancient trees and buildings absolutely smothered in that, which
sometimes DOES root from the stems, and grows more densely, and is
evergreen, and in its adult life-stage becomes in effect an aerial
shrub. Compared to Hedera, Parthenocissus is a dainty Victorian lady,
wilting away every autumn. I think a lot of people are just afraid of
what real Nature actually looks like.

Sorry if there was any confusion. I did not mean to say that the stickers or
tendrils burrow into your wood siding. What I meant is that the actual stem
will force its way between narrow openings. As the stem matures and grows
thicker in diameter, it can force that narrow opening wider. The ivy you see
growing in the Ivy League is growing on stone or brick buildings. Not much
is growing on wood. Those universities also perform routine maintenance to
keep the ivy where it is supposed to be and away from windows, doors, and
other vents.
