Vinegar acts as a desiccant. It dissolves the protective coating on the leaves of the plant causing it to dry out and die if the temperatures are warm enough. It usually doesn't destroy the roots and sometimes the plant may come back if there is enough energy in the root system. Dandelions have a large taproot which makes them difficult to kill with ...

Yes, he is right - you need to remove all the tap root, right down to the pointy bit at the end, or it will regrow, usually producing a 'double' plant, that is, with two lots of leaves as if there are now two plants.

It is difficult to answer the question of whether or not it is safe to eat dandelions or other plants that have been treated with this herbicide. You'd have to know how much iron the plant has actually absorbed in the part you intend to eat and whether that amount of iron would harm you. The main ingredient is chelated iron. Chelated iron is sometimes ...

How much salt did you use? What was the ratio of salt to vinegar in your anti-dandelion solution? Grass in general likes neutral to alkaline soil, and salt is anathema to most plants in general (although not all) so these will need to be either 1) diluted until it is no longer an issue or 2) counteracted in some way before the grass will be able to grow ...

Let me just preface this by saying that I remember when I took that photo (which, based on the time stamp, was back in April 2013), I had searched on the internet with no success: various searches by image failed, and searches using keywords like "dandelion" or "star dandelion" were hopelessly futile. And just by sheer luck, Ben Welborn's comment ...

Most weeds are opportunists. If your grass is not doing well, weeds will proliferate. Aerate your lawn by pulling plugs of soil out of your lawn. Go over it as many times as you can. Allow the plugs to disintegrate on top of your...lawn. Get a soil test done. Find out what nutrients are low, high, acceptable and what the pH of your soil is...do you ...

To understand why you have dandelions in the first place goes a long way into preventing them. A dandelion is not a "weed" it is what is known as a Pioneer Plant. Pioneer species are hardy species which are the first to colonize previously disrupted or damaged ecosystems, beginning a chain of ecological succession that ultimately leads to a more ...

So no presents for you under the plastic then! I'm glad really - that larvae you found could be the larvae of a moth or butterfly because its not immediately recognisable as a leatherjacket, but might have been. What's odd is you found it actually under the lawn, and that isn't at all typical of moth larvae. First, I'd note that your lawn is cut way too ...

Over time,your lawn will become largely a mix of dandelions and clover, because both will out compete the grass for nutrients and water. Since you don't use any chemical treatments, you could harvest the dandelion leaves and use them in salads or in cooking generally, they're a very useful source of healthy greens. Some varieties of clover can be eaten, but '...

The earth looks very compact and doesnt from the photos look like there is a good level of good quality top soil. for me, you need to get some good soil, compost and gypsum on top. poke holes and losen the ground and concentrate on the soil. once that is good, grass will be easier to get going. I have tried many times to bring lawns back and its much ...

The vinegar will persist in those spots as a lower pH soil. Vinegar is used as an herbicide (a much higher percentage than what we use in salads) and prevents anything from being able to grow...great for driveways for instance. All one has to do is add lime to get it back into the pH range to grow plants again. I would dig out the dead grass and soil, ...

I know it seems like I'm carrying the "calcium" flag on this site as it seems calcium is the answer to almost any problem, but once again, if you want to be rid of dandelions, check your calcium levels: "The lawn on the left received applications of high-calcium limestone and gypsum; the lawn on the right did not."

Nobody touched on a few points to help control dandelion and thistle so I thought I'd add my 2cents even though this is an old thread. Also I'm curious how you made out since this is an old thread. Dandelions grow well in alkaline soil which most grasses do not. If your soil is alkaline your grass could be thinning leaving room for dandelion to grow. Do a ...

I disagree that this method is not practical. If you had a look at the size of my garden you will see that it does work. An important step is to behead all dandelion flowers before they go to seed to minimise the volume of seeds. Of course there will always be influx of seeds from neighbours lawns who don't bother to keep them under control and the important ...

I deadheaded the dandelions in my lawn a couple of years ago, tossing the yellow flowers into the grass. Much to my surprise, and chagrin, I later found that many of them had continued to develop into the seed stage, despite being plucked. Now I gather them up into a little cup and throw them in the trash. Can anyone recommend a good tool for digging ...

I would recommend working on the basics first before trying to repair the lawn. Firstly, I would remove all the weeds in the lawn and secondly I would fertilize the lawn. Also, make sure you are watering the lawn regularly as needed. You should start seeing the lawn improve quite a bit just from that. Then, if patches remain, you can try to repair the ...

The second landscaper is right. If you get someone else to do the job, they will either need to kill the weeds with herbicide, or they need to dig out each weed separately, extracting all root material, and that may mean going down 8 inches or more to get out a dandelion root. If this is not done, they will regrow through the new lawn.

dandelions and clover are harmless for lawns, if anything they're beneficial. Dandelions have big tap roots, which dig into compacted soils and bring nutrients to the surface. Clover is in the Pea (Fabaceae) family and is a nitrogen fixer In fact having these in your lawn is indicator your soil is compacted and nitrogen deficient.

I lost a lawn in my first house to weeds; I could not water enough with my well to keep the grass healthy. I sold the house with no lawn in the backyard; I had pulled everything out. I had better luck in my 2nd house with town water; since the lawn was new with the house, it never developed weeds. In my current house, there are weeds, so I put down Halts in ...
