Tips for home and garden: More about English Ivy
English ivy “deserts” have
sprung up all over the Pacific Northwest, and British Columbia is no
exception. Once it escapes garden confines, this invasive
import smothers valuable native habitat groundcovers, shrubs and
even trees.
If
you already have English ivy in your garden, keep it firmly
in check on the ground, and don't allow it to climb trees. Once it
climbs, ivy produces flowers, berries and seeds that are easily spread to
natural areas by birds. Ivy can eventually kill even
large mature trees, first by outcompeting them for light, and then
by making the weakened tree so top-heavy (especially when the ivy
infestation is drenched with rain) that a strong wind can blow it down. If ivy
has climbed any trees in your garden or in nearby natural areas,
here's what to do: Cut all the ivy stems on the tree trunk at chest
height, strip the stems down the trunk to the ground, and cut again
at ground level, as far away from the tree as possible. Leave the
remaining ivy up in the tree to die back over a few months before
attempting to strip it off, so as not to damage the bark to which
living ivy clings strongly.
Better
yet, invite all your friends over to help you remove the ivy entirely from
your garden! Hard work, but you may well be saving yourself (and others)
a lifetime of shearing, snipping, hacking, yanking, dragging, bagging and
bundling!
