Answer 1

Here's my personal suggestion followed by an article I found helpful in futher controlling your problem with liverworts;

I would suggest using a product called "Cinnamite". It has shown to be very effective in controlling liverworts in nurseries and diseases on turf.

"Cinnamite" is a synthetic cinnamon oil-based product used to control diseases such as powdery mildew and pests such as mites and aphids on a variety of plants. It really does smell like cinnamon and is relatively safe but in concentrated solutions will cause some irritation to your skin.

You'll find that you can achieve better control when spraying your plants in warmer weather versus cool temps. Within several hours after an application or "Cinnamite" you'll begin to see the liverworts begin to die. Repeated applications may be necessary for complete eradication but it's one of the best products available in controlling liverworts.

I conducted a word search using Yahoo and found the following dealer selling "Cinnamite" (Hydro-Organics Wholesale [phone]) but I'm sure you'll be able to find another dealer closer to where you live.


ALSO---I found this interesting article written by the University of Guelph that might help you;

The presence of mosses, liverworts, or algae in a lawn is an indication of poor growing conditions for the grass, such as poor drainage, low light, low fertility, compaction or acidity. The best control is to improve growing conditions as follows:

Light - If the lawn is heavily shaded, consider pruning trees to increase light. If this is not practical, some grass species or other ground covers are available which are shade tolerant.

Drainage & Compaction – Re-contour poorly drained areas so water runs off better. Drainage will be improved and compaction reduced by aerating or slicing the soil.

Fertility and Acidity - A nutrient analysis done by an accredited laboratory will determine if the soil is too acidic or low in nutrition, and will recommend what to add.

Following any of the above treatments, vigorously rake the grass to remove the moss, liverworts or algae crust. Reseed bare patches with a suitable variety of turfgrass.

Hope this information was of some help to you. GOOD LUCK!

Answer 2

Liver wort is related to ferns. Because of that it is more difficult to kill, than oh your average broad leafed weeds.

My first suggestion is to use a light powdering of gypsum. That will make the soil more alkaline, and help to dry it out. Liver wort prefers a moist acidic soil.

If that doesn't work, try to dry the area out manually. Cut back the watering especially in the spring and fall. Cultivate the areas that the liver wort is in, break them up.

I wouldn't bother with chemical controls like round-up or other weed killers, as they just won't be as effective on this primitive sort of plant. The spores of this plant grow quickly, so that even if you kill off the parents, it will be very little time before the children take their parents places in your garden. Additionally those chemical controls will also kill your garden plants.

You might find a chemical that will kill moss. That Might, and I emphasize might, kill the liver wort. Again I think it will harm, maybe kill other garden plants, but it is formulated to work in lawns and not hurt the grass (grass isn't broad leafed, but most of your garden plants are). Scott's makes a product like this, as does Safer.

I hope that this helps
Good luck -

You may be money ahead by paying someone to get rid of your weeds , adn then putting down a pre-emergent twice a year, and spot treating weeds with a sprayer and Speedzone in the spring and fall. This way you will get the right product applied at the right time., and there will be no unexpected injury to your turf and ornamentals.

Answer 4

Try using round-up concentrate on the weed. Paint the concentrate on with a paint brush or foam brush all over the plant.
If the round-up doesn't work, or doesn't completely kill the plant, apply again after a couple of weeks.
Also, consider covering the weed, it will die without sunlight.

Answer 6

When all else fails, try a shovel. Salt will also kill any living plant/weed.

Answer 7

If all else fails, bag it up, and sell it on Ebay. You'd be amazed at the stuff people will buy! LOL!
