How to Control Japanese Anemone

Hello all

I hope you are Well.

I have 3 Japanese Anemone Plants in My Garden which, due to me not being able to get into the Garden since August, have spread beyond where I want them.

What is the best way to Control their Spread?

Is it simply a case of pulling up the New Growth that I do not want?

Thanks in advance

Kevin

 

Beautiful as they are Japanese Anemones are a real thug if they like your soil. Every bit of root will grow. I dug out one in my back garden which was taking over and was still digging out bits of root which had shooted (shot?) five years later so I would say yes keep pulling unwanted growth but you have to keep at it. Mine was the single white one and some varieties are not so vigorous. My sister gave me a shorter pink one with crinkly leaves called Crispy Curly which isn't half as bad. I do like the white ones though.

 

Hello @Baalmaiden

Sorry, I missed your Reply.

So, basically, just dig up the Shoots that are not needed?

Sounds Simple enough

Thanks

Kevin

 

And the best of luck. We were still trying to remove this after 20 years of digging, pulling and weedkiller.

 

I don't find it too much of a thug here. Yes, it keeps growing even after being butchered, but it's not pentaglottis thuggery so can be controlled

 

Well against all...we have never been able to keep them. Had some from our village garden group decades ago (white) and they flowered but never spread. We have not had any for many many years. Maybe that is good news!

 

I keep them in pots but I do have a dwarf variety which is well behaved and stays in a manageable clump in the garden.

 

Completely well behaved here, in fact I wish mine would bulk up and spread a bit

 

I have two J Anemones in my front garden and was puzzled at first reading how thuggish they can be... mine have never spread or become a nuisance. I dug out the label just now and it's a variety called'Honorine jobert'. It's a clump forming anemone with masses of white flowers. Mine go well with my plum coloured Huchera and rose, in the same border.
Good luck with yours, @Kevin Cowans.

 

I get the impression the pinks are more thuggish, especially in lighter soil.
I don't like them, so I only grow the whites. They generally prefer wetter conditions, and I don't find them invasive at all, so it may be down to the site. We're on clay, and even when improved, they behave well. I get some seedlings, but if they're not where I want the, they just get pulled and binned.
H. Joubert is a very common, and popular variety @pattie and although I don't have it in this garden I've grown it in others. Whirlwind is nice - semi double, and a bit shorter. I also have one called Andrea Atkinson which is similar to H.J. They'll take a good bit of sun if they're happy below ground too, but the whites are great for brightening up shday areas.

 

Honorine Joubert is my favourite but not happy here at all. I inherited a small Hapsden Abundance which is now slightly bigger than small. Acoording to the textbooks they should be happy but

 

We have inherited a patch of what I believe are Japanese anemones. Probably an area of about 10ft by 5ft, but have either self seeded or sent runners under a concrete path, and are growing in too many places than we would like.

We also have a peony that is poorly sited, and wondered whether it would be possible to remove the anemones, and replace with the peony, and perhaps several others.

From what others have posted here, it looks as though I have a major task on my hands.
Or would I just be wasting my time and effort?

 

@RowlandsCastle, I'd say you would be wasting your time unfortunately. As some of the others have said, they spread by underground runners, not by self-seeding and can be absolute thugs. I just pull the shoots up whenever I see them - which is often. Weedkiller doesn't seem to work at all. I've got both the pink and white varieties and they both spread here.

 

We are the one in a million! Ours disappeared many years ago. No idea why. They never spread and it was the white one.

 

I like them, the problem is they like my garden. I have both Honorine Joubert and Hapsden Abundance fro the first five or so years they were well behaved and then off they went and have been a spreading menace requiring harsh control. H Joubert got moved to a rough patch of grass under conifers, it gets mowed flat every so often keeps coming back though. It also still comes back where I originally had it.
