Is yellow archangel weed (aka Lamium or Lamiastrum galeobdolon) taking over your garden beds?
Yellow archangel used to be for sale in many nurseries. But now yellow archangel is recognized as an invasive weed. Fortunately, we’re seeing less and less of this Class B Noxious weed is being sold these days.
But, yellow lamium is still taking over garden beds everywhere. And, we’ve dealt with it as an on-going urban issue. That’s mostly because we can’t always control what happens on the other side of our property lines.
Can Yellow Lamium (aka Lamiastrum galeobdolon) be useful:
Like the bindweed and blackberries and holly that the renters next door do nothing about, they also allow yellow lamium to thrive through neglect.
To them: “Yellow lamium is pretty when it blooms yellow, and those silvery leaves brighten up dark corners.”
To us: “It’s a non-native that spreads fast even in deep shade. Plus, it can easily smother out native plants. Oh, and it stinks!”
And for some, yellow lamium is an herb worth cultivating. But we’re not going to get into that here.
As well, yellow archangel does flower to feed pollinators. And it can be pretty. But there are other more worthy plants to cultivate instead of this bully.
Here’s how to get rid of yellow lamium weeds:
If you’ve got yellow lamium in your garden, get it out from the roots sooner rather than later. That’s because once it creates a dense patch, it can be difficult to remove all of the roots.
And if you’re going for it, find a clump and dig out the entire root. As well, if it has sent out runners — above ground or under ground — follow those runners to then next clump. Then, remove everything.
In fact, using a garden fork to loosen moistened and drained soil around a big patch first. Then follow with a hand tool. This makes getting all the roots out easier.
And don’t skip the part about moistened soil. That’s because you’ll probably leave some roots behind if you’re pulling from rock-hard Earth.
Finally, once you’ve removed this plant, don’t put yellow lamium into your compost. That’s because it will easily resprout and take over your compost pile.
