Bulb log 46 Liverworts

[Gerry Webster]

Lesley - you are forgiven.

Thank you Derek and lesley. Good information.

Does anyone know whether darkness really kills them.

Roundup seems not to affect my mosses - at least not those I am happy to have. However it seems very deadly to Athyriums.

Cheers
Göte.

PS
my Helleborus thibetanus are up 5 cm - this cannot end well. Our cold period is usually in February. Did they believe that the -5-6° we had in November was the winter and that it now is spring??

Covering liverworts with sand does kill them but whether it's being in the dark or suffocation, I don't know. And again, the dead stuff still has to be removed if it's over a plant or seeds.

Dear friends,

In Holland, there is a Bayer product called ´Mogeton´ , it contains quinoclamin and kills all mosses and liverworts. It works very well. Don´t know if you can buy it in England.

Also magnesiumsulfate (MgSO4), used dry as powder, kills it.

Good luck!

[Lesley Cox]

But Martijn, does it kill other plants as well.? Can it only be used in areas where nothing else desirable is growing or can it be used on, for example, pots with seedlings growing in them?

Lesley,
A copy of the label information here:

MOGETON

Definitely not one for the amateur.  Would definitely kill anything in a pot  

[Martijn]

Hi,

The Mogeton from Bayer is safe for plants (always test first). It is used on a large scale in the Dutch Nurseries.

Thanks for the link.  You would never have quessed from the label that it was safe for plants.

Martijn

Thanks for the link.  You would never have quessed from the label that it was safe for plants.

 The label in that link suggests that the chemical is offered as a s usrface cleaner for hard landscaping.... it may not actually licensed for use on plants in the UK ... even if it is widely used abroad in that context......... has anyone any further knowledge about that?

[Lesley Cox]

We have assorted stuff here for a similar purpose - spray ons for concrete steps, paths, algae on timber etc. I'd never think of using them on plants.

[Luc Gilgemyn]

Well at the bottom of the label, it does say something about (un) safety to plants    :

"
Safety to plants
Mogeton is unlikely to harm higher plants (except ferns) and surfaces may be treated right up to lawn edges
or behind bushes. However, general over spraying of vegetation is bad practice and should be avoided.
Mosses and liverworts can be damaged if touched by the spray."

Thank you very much Martijn !!!
This is most useful and encouraging informetion.

Just reading the posts on liverwort and I started thinking I haven't had much the last 18 months.  I wondered whether it is because an old gardener told me to put yellow sulphur on the compost before adding grit as he said he found it prevented stem rot.  Question is has this reduced the problem as I only get the odd bit on pots these days.

I was told that Baking Powder kills it (that's Sodium bicarbonate and Tartaric acid, I think). I've tried it a couple of times on seed trays and it worked (just applied it as a powder sprinkled on the leaves).
