In the thick of early-COVID grief-fog, I sought a much-needed achievement badge by contacting The Macphail Woods Ecological Forestry Project about its landscape consulting service.
Catherine had always been the sexton of our churchyard and, in a move to establish dominion, I thought I should get to know it, and perhaps plan for its future.
A few days later I was lucky to take MacPhail’s Gary Schneider on a tour of the backyard. To my surprise, rather than hitting me with a “you need to get some native plants in here stat” prescription, Gary, instead, led me on a much more philosophical conversation about what I wanted the yard to feel like, what I wanted to use it for. It was, it turns out, just what my soul needed.
On his way out the gate, Gary pointed at an outcropping of tall bamboo-like shoots between our deck and the fence.
“You probably want to do something about that,” Gary said, “and your neighbours will thank you if you do.”
Gary explained that what he was pointing at was Japanese knotweed, an invasive species that the PEI Invasive Species Council describes in dire terms:
Japanese knotweed is one of the Global Invasive Species Database’s 100 worst invaders. It grows in a wide variety of habitats and tolerates a wide range of adverse conditions such as deep shade, high temperatures, salinity, and drought. It grows in dense thickets that shade out neighbouring species and spreads readily via underground rhizomes. Once established, it generally takes great persistence and several years to eradicate. Japanese knotweed is widespread on PEI.
And thus began my descent into a kind of interspecies hell, me against knotweed, a battle that played out both in the soil and in my grief-burdened psychology, which didn’t really need a brooding subterranean foe to fuel its nightmares.
But I dove into the battle, grief or no (maybe it was exactly what I needed).
I consulted with my neighbours, with Gary, with Island Nature Trust, with the Invasive Species Council. I read horror stories from the UK where properties were rendered unsalable because of knotweed invading their foundations. I Googled and Googled and Googled.
I learned from my mother-in-law that Catherine, unbeknownst to me, had been quietly waging her own battle against the knotweed before she died, trying in vain to cut it back every spring.
The consensus: short of chemically poisoning the knotweed, which I wasn’t prepared to do, my best course of action was to remove as much of the knotweed as possible, as deep as possible, and then to cover the area with a thick black tarp, cover the tarp with several inches of soil, and then maintain vigilance.
“You just have to be diligent. If you don’t let it photosynthesize, it starves itself.”, Gary emailed.
So that’s what I did.
The first year the knotweed was tenacious, finding ways out from underneath the tarp every few weeks or so. I emailed my neighbour a month into the project:
I finally saw evidence of some serious knotweed on our side of the fence tonight, coming out from underneath the tarp-covered area right about the fence line.
This wasn’t gentle young “shoots,” but ½ inch thick growths that worked their way under the tarp to daylight.
I was equally tenacious, pruning it back every time I saw a shoot. My neighbour did the same thing on her side.
Over the winter I updated Gary:
Over the course of the summer, in parallel to managing the knotweed, smothering it, but seeing its tenacious shoots, I engaged in a similar relationship with grief, eventually, in both cases, coming to a sort of symbiotic relationship. Both will be with me for a long time, but, with attention, I can avoid getting strangled.
The second year was about the same.
So was the third year.
Four years in, things had started to taper off: I was still seeing shoots here and there, but managing them was no longer a part-time job.
This year, 2026, six years on, is the first year that I’ve been able to declare a tentative victory: I’ve pulled out a determined shoot or two, but it does seem like, finally, the Japanese knotweed is “under control,” if not eliminated.
Along the way I’ve developed a second sight for knotweed: I see it everywhere in Charlottetown, especially along Confederation Trail. When it’s in full flush it can seem like it’s growing a foot a day and will eventually consume everything in its path.
While it seemed at times that thoughts of knotweed would plague my nightmares ceaselessly, as I’ve managed to keep it at bay in the back garden, my mind has quieted. Maybe I actually did need an external foe to act as a metaphor for grief, and perhaps the patience and tenacity I needed to fight the foe were qualities that needed a boost.
While it’s hard to be thankful to the knotweed itself—we are still mortal enemies—I am thankful to Gary for identifying it, for the distraction when I needed one, and for the path to victory when I needed a victory really badly.
