Emerging Knapweed, as far as the eye can see.

Trigger Alert: This blog post contains references to maniac-level gardening, obsessive-compulsive tendencies and other forms of mental illness.

In the early 1980s, the City of Los Angeles was confronted with a difficult problem. Renowned for its levels of air pollution, how would it deal with the upcoming Olympics? After all, you couldn’t expect world quality athletes to do their best breathing the yellow-brown gas that the city’s denizens accepted as air. Every unsolvable problem has a similar solution curve; you do what you can.

If you have followed this blog for any time, you are probably aware of my ongoing battle with the evil, invasive, Spotted Knapweed. I cannot complain, the knapweed was here when I purchased the property–I just didn’t know what it was. When Rick and I arrived to develop it, we joked that, if it weren’t for knapweed, we’d have no weeds at all.

We had it backwards. We had no weeds, because of the knapweed. Sigh. It is an earnest and dedicated competitor. As a refresher, remember that knapweed competes on a number of fronts: it poisons the soil around it (the toxins remain for up to three years after removal); it absorbs most of the available water in its fleshy roots (starving neighboring plants); it spreads, both by seed (viable for seven years) and by underground spreading roots; and it colonizes disturbed soils. If you pull it up–and any part of the root remains–it will return, which means that tilling is a disaster. Knapweed eradication is a myth.

And still, one must garden. We have a dual challenge, poor sandy dune soils and knapweed. So long as the knapweed remains, the soils will never improve. We were lucky, even in our knapweed ignorance, we knew the soils were poor. So when we planted the orchard we dug big holes. Very big holes, perhaps 5 feet across and nearly as deep. Our neighbors raised their eyebrows and inquired. We removed most of the native sand and amended heavily. Unbeknownst to us, this solved our knapweed problem. Our new trees thrived–even as friends of ours, with supposedly better soils, lost entire orchard plantings to the knapweed’s toxins.

But our gardens failed to prosper.

At one of our bee meetings, the guest speaker from the local Soil Conservation District, came to discuss bee-friendly landscapes. That’s how I learned about knapweed and its ugly dual nature. Sure, it’s bee-friendly, but that’s as far as any friendship extends. I did my own research and the prognosis was grim. Understand, we have acres and acres of knapweed. And we won’t use poisons. After all, we are beekeepers. I asked a friend of mine, with experience in park management, for advice. She asked if it was too late to consider selling.

And so we steeled our resolve. We narrowed our focus to the garden area–a mere 50 X 100 foot oasis of fruit trees and raised beds. Surely we could manage that. Let the knapweed, and the bees, roam the acreage–but save the garden.

I’ve been pulling knapweed for three years now. We’re making headway, but it’s a worthy opponent. Pulling weeds was my ‘free-time’ activity. I’d do some in the spring, but mostly the early season was for getting the garden in. And summer and fall were full of knapweed endeavors. After nearly every rain, I/we pulled it by the wheelbarrow loads. It’s exhausting.

A pattern emerged. Our main focus was around the garden beds and the fruit trees. The areas along the fenceline, and other open ‘yet to be developed’ areas tended to get the least attention. Naturally the weed dug in there, for the battle. Late season efforts only slowed the knapweed’s hegemony. By then, rootlets had spread–guaranteeing reinforcements for the next season. A thankless, and never-ending task.

What we needed was an early season surge. And, what else can you do in a pandemic lockdown? So this was it. We (mostly me, but Rick’s a maniac, too) have been up to our eyebrows in deep weeding. Every. Single. Knapweed. In some areas, the knapweed was so thick that our efforts left the soil barren. (Remember, knapweed loves disturbed soils. Sigh.) We re-seeded with soil-building plants, even knowing that the knapweed’s toxins might defeat the effort. So far this spring, we have over a hundred hours in, between us, in the back-breaking effort of pulling this damned weed.

We’ll take a break now, and turn our efforts to growing some vegetables. After that, we’ll be back to knapweed-maintenance duty.

In Los Angeles, the City wrestled with how to resolve their pollution problem. They limited driving, especially near competition venues. They located most of the events on the west side, nearest the ocean breezes. Ultimately, language was their biggest success. They changed the standards. Voila! Objectives met!

We, too, have re-framed the battle. It’s unlikely we’ll eradicate knapweed. We don’t even use that word anymore. And we’ve narrowed the playing field to the garden/orchard area, ignoring the acres and acres of adjacent infestation. (Hell, the bees like it, right?) We don’t even consider abandoning ‘eradication’ as a retreat. Facing similar obstacles, many pollution agencies have adjusted changed their mission–it’s about ‘management’ not ‘control.’

We know that we will always be fighting knapweed in the garden. Even if we are fully successful, weeds are not great respecters of fences. The objective now is to keep enough area clear so that we can go about the business of keeping the orchard and growing enough vegetables for our own consumption. We’re not farmers, we’re gardeners. And that’s enough.

Sigh. Knapweed (only) removed, and nothing left but disturbed soil.
