Willowherb

Symptoms

Willowherb will take over any domestic garden, spreading by seed and tough underground roots to form dense clumps.

Find it on: all over the garden
Time to act: early spring to autumn

Overview

Willowherb, or fireweed, Chamerion angustifolium, is a pretty plant that looks at home in a wild garden, but will take over any domestic garden, spreading by seed and tough underground roots. Left unchecked, it will invade the space of other plants and restrict their growth.


Solution

Willowherb will take over any domestic garden, spreading by seed and tough underground roots to form dense clumps.

Organic

Keep digging the plants out. Willowherb can be forked out fairly easily - especially when the soil is loosened after rain - and will not survive repeated cutting or pulling.

Chemical

Use a weedkiller such as glyphosate. Spray directly onto the plant and avoid spraying on a windy day and near other desirable plants.

why do my seedling grow tall like cress?

I have this in my garden and it is a devil to control! Already I can recognise it reappearing, in places where it wasn't growing last year. It is easy to dig up but you will need to do it weekly to keep it under control as it is fast growing. I have resorted to glyphosphate, but this will work for a number of weeks, so you will need to reapply regularly. It doesn't help that my neighbours allow if to grow and take over their garden, so I have little chance of ever getting rid of it!!

You are doing all you can do with the weed killer, could you try asking your neighbour if you could kill theirs as well.

Try not to let it go to seed,

If I may. Yes Willow herb is an attractive plant. Yes, very invasive, by means of self seeding and underground rooting.
It also has another side to it's life. It is also a Rust carrier. This rust is mainly taken up by Fuchsias. I have to admit this is most strange to me. I grow many fuchsias, I have no Willow herb close bye, yet I sometimes find rust on certain plants. Any suggestions?

I have lots of willow herb of several varieties.

It is loved by butterflies, the Great WH in my wilderness, a marshy area, is always alive with fluttering wings in the summer.

Rosebay is beautiful and I let it grow in the wilder parts of the garden. It is host to the elephant hawk moth, a beautiful thing to see. Curiously, like the rust, this also likes (eats!) Fuchsias, but I still manage to grow them without problems. Oh, and the dry stalks make great bonfire starters
