RE: How do you get rid of Dollar Weed (Penneywort)

There are 2 products that can rid you of dollar weed. The first one use only if you do not have dogs or cats, it is Bonus S, you can get at Wal-Mart, Sams, or any box store. Then there is Wipe-Out, this it great to use on your grass, but do not use it in your flowerbeds. The only way to get rid of dollar weed in the flower bed, is to get a hose, and soak the bed, and just pull until it all comes out. Its a lot easier than it sounds. Barbra,

Thanks so much for the help! Luckily, I don't have it in my flowerbeds -- just the St. Augustine. :)

RE: How do you get rid of Dollar Weed (Penneywort)

BEFOR you put any weed killing product on St. Augustine, carefully read the label. Even products such as Bonus S tells you not to use the product under the drip line of trees or around shrubs and other valuable plants.

RE: How do you get rid of Dollar Weed (Penneywort)

Also, Wipe Out acts much the same as Roundup. It kills weeds AND grass! You've been given some very questionable advice.


 o
RE: How do you get rid of Dollar Weed (Penneywort)

We do not feel that you have been given any questionable advise. It was recommended to us by a nursery in Rockport Texas when we were fighting dollar weed. It is a product of green light. We have been using it for over 5 years on our st augustine grass, and have never had any adverse effects to the grass, it is for broad leaf weed killer, it will not hurt your grass. Do not use in your flowerbeds, it will not hurt most flowers, but will kill anything from the herb family. I would think if any adverse affects to st. augustine grass came from using green light, wipe out, it would be related to impoper application. As with any other product. Barbra,

RE:How to get rid of Dollar Weed (Penneywort)

I just went on the internet, and it says it is for all types of lawns, not just st augustine, it takes about 10 days before you see all the dollar weed dry up and die. It is not overnight. I have posted the attached add for it.

This is the best product we have found to kill the dollar weed at the coast( we are in Rockport), but we have to bring it from San Antonio, they are always sold out at the nurseries, and Wal-Mart, sometimes we can find at Lowes. Barbra,

RE: How do you get rid of Dollar Weed (Penneywort)

Thanks again to all the responses! I think I will check with my local nurseryman to see if he recommends Wipe-Out or another product. I was told by another person that Wipe-Out works best in cool weather. We live in Huntsville (near Houston) so the cool weather looks like a thing of the past this coming week. Thanks again, Happy Gardening and Happy Memorial Day weekend. Stay Safe! Jeani

RE: How do you get rid of Dollar Weed (Penneywort)

I would recommend that you check with your local nurseryman, that is what we did. The wipe-out by greenlight that we use at our coastal home near Corpus Christi, can only be applied if it tempature is above 70 degrees. I am not aware of the other product that is used in cool weather. We only have problems with dollar weed in the spring and summer when it is well above 70 degrees. Barbra,

RE: How do you get rid of Dollar Weed (Penneywort)

Why did you post the question in the first place? You are listening to folks who have never used this product. I am so sorry I waisted my time trying to help you. I have not posted on this forum since October, and noticed that most of the older members are no longer posting, now I know why. Barbra,

RE: How do you get rid of Dollar Weed (Penneywort)

Suggest you check the web site: aggie-horticulture.tamu.edu/plantanswer/turf/turfweed.html. Now, Barbra, sorry you have a problem with people disagreeing with you. I have been maintaining my St. Augustine lawn organically for 37 years. Have seen neighbors kill their lawns, shrubs and perennials with products labeled for "southern lawns". I personally use corn gluten meal as a preemergent. If I have a perennial weed I spot treat itwith 15% vinegar.


 o
RE: How do you get rid of Dollar Weed (Penneywort)

We also use corn gluton meal twice a year, in April and October as a per emergent. We also use molasses and gound alfalfa as fertizer, also cracked corn meal to treat fungus in our St Augustine and Flo-Tam Grass. We tried the 10% vinegar to kill bermuda grass, but it spread and killed all the other desired grass around it for 2 ft, we will never make that mistake again. It will not kill dollar weed, neither will round up( purple cap). My husband plans to use the vinegar with orange oil to kill ant mounds. We put down living mulch in March, and then benifical nematides twice a year to treat grubs, ants, and flees, as soon as we see the fist june bug, we spray them in our yard. Our yards are emerald green. We have an acre with beautiful tropical flower beds in Rockport, plus an over sized lot in San Antonio. I had members from this forum, visit both places. My father was an organic Texas farmer, I use to dust his brockley, cabbage, and tomotoes with self rising flour when I was a small child, it kills tomoto worms. I am over 60 years old. Barbra,

Correction 20% vinegar(type-o) Barbra,

Well I'll tell you one that has me stumpted. Wild strawberries. Presume they were planted by birds.

I love the self rising flour idea for tomatoes. I am over run with worms this year eating everything and I hate to use pesticides. Thanks for the idea!!

How do I know what kind of weed I have? I have this grassy-like weed. It grows from a center point and radiates out. When I pull it out it is fairly easy to get it out, but there is so much of it! And it is there every spring.
Ideas?

RE: How do you get rid of Dollar Weed (Penneywort)

The active ingredient in Bonus-S is atrazine. Buying Bonus-S is an outrageously expensive way to get atrazine. I don't like this stuff for reasons you will see below. However, it was the only product that really worked.

It is available in liquid form and, one bottle will cover a whole-lotta ground! It will not kill your St. Augustine but, will absolutely kill the dollar weed. Dollar Weed has those numerous long rhizomes and, regardless of how well you spray, it seems that some of these rhizomes survive. It may take several applications to completely eradicate your dollar weed.

Atrazine was responsible for ruining my vegetable garden the year Katrina hit (2005). It killed a couple of my citrus trees also. Atrazine hangs around in the soil for a looong time. So, pay close attention to where your lawn drains. Any rain-water containing atrazine that drains near plants you like may kill them. This applies whether you use it in the liquid form or in Bonus-S.
