I have a half-acre garden in South Surrey and I've been battling horsetail, Japanese knotweed, rampant buttercups, creeping spurge, English ivy, etc quite unsuccessfully for the past 14 years. 2 years ago, a bit of fireweed showed up out of nowhere and now it's everywhere. I have tried digging it out, but it always seems to return 10 times stronger than it was before I dug. Any suggestions?
In the Yukon it eventually gets squeezed out by other stuff like wild roses. (The roses are worse. They don't seem to get squeezed out by anything.) Digging it out or tilling it will just make it spread like crazy. I honestly don't think there is a solution. Sorry. Carl
Fireweed is an early seral species -- it depends on disturbed soils and environments. With all the weed removal (and likely soil disturbance) you've been doing, it sounds like ideal conditions for fireweed to prosper. Removing it by weeding is likely not going to fix the problem, so you'll need to suppress it. From the Royal BC Museum: And a comment from the PNW Natives listserv:
Thanks Daniel. Making sure the fireweed has "plenty of competition" sounds like a great excuse to fill my car at the annual UBC plant sale in a few weeks :)
At least, unlike the other things you've been battling, it's a native plant where you are. Just say you're starting a natives garden and enjoy the spectacular flower show it puts on ;-)
Spectacular indeed! And absolutely everything looks beautiful photographed in a field of fireweed. Babies, motorcycles, grizzly bears... consider leasing the plot to a photographer for a backdrop. (Sorta like life dealing you lemons so make lemonade...) Cheers anyway Carl
When they're young you can eat them-cream of fireweed soup-yum!! I remember when I used to work for fisheries and there was a hatchery up north and one of the guys was death on fireweed. When ever he came there he decapitated any plant he saw. After he left each fireweed he had trimmed sprouted multiple flower heads and had 10x the amount of seed a normal plant would have had...
Anybody wanna buy a house in South Surrey? It comes with a lovely 1/2-acre garden with a beautiful collection of native plants? Anyone?
We pay a woman up the road for her fireweed honey. Wonderful in your tea or on toast. Bring in some bees while you're waiting to sell. Carl
... earlier this year someone posted a question about invasive "weeds" in a brand new landscape in Surrey somewhere - I wonder how that has worked out. in any event - I related to their story because I paid thousands of dollars for all new decent soil - only to have the biggest invasion of fireweed - yikes. The people around us with swimming pools were not impressed (the fluffy stuff) It has taken me years to get rid of it - just keep pulling and do it BEFORE the fluffy seeds drift off - you will be covered in it - I mean, to the extent of undressing in the garage and hosing off before entering your house. i had no idea it was so underground invasive, like that alstromeria and morning glory. ps - I re-read some of the older posts - the person who talks about the fish hatchery - and the person pulling fireweed - yes, that is my experience - pull one, end up with 10 the next month (assuming it is growing season) yet it looks so darn pretty in those calendar and postcard photos of alaska and yukon etc. I had no idea til it ended up in my garden. argh. tho the hummers like it. So the few plants that still remain, I leave them and then immediately pick and pull before the fluffy seeds start to fly in the wind.
I am (somewhat) happy to say that I no longer have a fireweed problem. I followed the advice offered here and just kept pulling up the plants (without disturbing the roots) as soon as I saw them. This seemed to take down their numbers pretty quickly. At the same time, the buttercups, blackberries, and horsetail continued to multiply at an alarming rate, thereby crowding-out the fireweed entirely. I'm not sure this is a success story :(
ouch it really underlines the importance of buying sterilized soil and if not a DIY project, to make sure in your contract with the landscaper, you spec "sterilized soil" like some other people on this board here in Coastal SW BC - I learned that the hard way. I wish the "industry" (the professional garden landscape service industry) in BC had some association standards about sterilized soil so that consumers like us are more aware and realize that it does make a difference (as you have discovered too). I know I spent THOUSANDS on soil (we had to due to various renovation and new septic install etc reasons on a small lot) - and it came full of weeds (that hatched after the delivery and install) oh - and a "head gasket" among other found objects. the proverbial "bad apple" supplier shines a poor light on the others who may be supplying decent sterilized clean product.
