Google Lens inconclusive. It's all over my driveway. I have so far tried patio magic and glyphosate.

Thanks!

Mix vinegar with water…like 1 part vinegar to may be 3 part water. Put it in a sprayer and spray it. Acidity is deadly to them.

It’s a type of moss, I forgot the same. I get them on my bonsai trees. They spread really fast and really easily.

You need proper glyphosophate.

Not the stuff from DIY stores / garden centers, but the pro grade.

Basically ~500g/L (50%) or there abouts.
Most places won't sell it to you without a licence, but unfortunately no consumer weedkillers are any good. It's the consequence of regulation and idiots being unable to actually follow instructions and use nasty stuff safely.

(For reference, the consumer product Pathclear mentioned above is 125g/L (12.5%))

Try sprinkling biological soap powder on it - it doesn't matter how cheap it is, so don't go wasting Ariel if you've got cheap stuff in the house too.

Leave the powder on for as long as it takes to kill the plant. If there's any powder left over, use it to clean your drive too as an added bonus.

I used Gallup 360 from Amazon but did dilute it.
 
That's only 360g/L assuming you diluted right.

Still ought to be OK-ish though.
It needs to be absorbed through the leaves though, not the roots, which is the classic mistake amateurs make when spraying.
If the leaves are waxy, try something like a really stiff brush over before spraying to break the coating.
 
It's Liverwort, and it thrives in damp conditions. I have exactly the same in certain sections of my driveway and it's pretty persistent stuff.

Most weed treatments (including the pro grade glyphosophate) might briefly reduce it, but won't control it for long and it will come back strongly. Trust me - I've tried...

Physical removal with a scraper and stiff brush is the best way to properly remove it, but again - it will come back over time so you will need to re-do on a regular basis.

When using glyphosophate on it are you putting some fairy liquid in to act as a wetter? Its waxy leaves mean it will just bead on the surface of the leaf and not be absorbed properly if not.
 
Thanks to all for the advice in this thread. I'll try your various techniques! Loving the idea of setting fire to it tbh :cool:.

No I hadn't tried that. A 'wetter' for something that's already wet is going right over my head!

The leaves may be naturally waxy.

Glyphosate is poor on waxy plants in general as far as I know so may be a reason for the poor performance.

On a side note, its too cold now for weedkiller really, it works much better in early Summer when the weeds start growing fast.

At this time of year burning it may be the best option.

On waxy leaves the glyphosate sits in beads, like when you washed your car and waxed it. It beads exactly the same. The wetter breaks the surface tension in the spray and makes its spread out all over the leaf.

As Dave28 said, it works by being absorbed through the leaf, so you are best using it when its nice and hot and the pores on the leaves are opened up, when its cold like this it will still work but its far less effective. By that nature its also not great on things like ivy and other waxy leaved plants so you often need to put it on much stronger and even then its not great.

Something like SBK Brushwood Killer is better for woody / waxy leaved plants, but again should be used during summer when the plants are growing.


Edit;

SInce found the following, so actually nothing chemical wise will work.

Controlling Liverwort?

As it is not a plant, weedkillers have no affect on Liverworts. They do not work in the same way as plants. The easiest way to control it is to scrape it off the soil using a spade or hoe. Some say a soluble iron solution does discourage it (in a similar way to dog lichen) however this would only over keep it in check and wouldn’t really control a large patch.

The most reliable way to control Liverworts are to improve the environmental conditions. Improve soil drainage by aerating and brushing in a horticultural sharp sand. Top dress with a fresh topsoil or a good quality compost and reduce shade by cutting back shrubs and overhanging tree branches. This will encourage grass and discourage the Bryophytes.
