So to see weeds thrive in varying environments is no surprise. Two weeds are part of a system so you need to look at the whole picture. There is science but field research is long and arduous enjoy the processes.
While I have no idea why we are revisiting a 14 year old thread, I would just add that dandelions are not an indicator plant at all!! They will grow anywhere other than boggy ground, tolerating a soil pH of 4. They are also found in nearly every country in the northern hemisphere, from subtropical climates to the arctic circle.

Darn, so I guess that means I'm not especially talented at growing them? Like 1 Save. Sort by: Oldest. Newest Oldest. Or Neutral soils. Like Save. The idea that agricultural use of peat contributes to an unsustainable harvest rate is far from the truth. I would concede the point if everyone in Canada and the northern tier of states was burning it as fuel, but consider: In Canada alone, there are more than million acres of harvestable peat bogs - that's harvestable.
Not taken into account are the millions of additional acres of bog that are not deemed harvestable because of their size or location. If we make the conservative guess that the harvestable portions of these bogs are 10 feet deep, that means there are probably more than billion cu.
That doesn't even take into consideration what's available in Europe, Asia, or places like New Zealand where they also mine peat.
You'll find the math accurate and conservative. It's more likely that the next Laurentide Ice Sheet will be upon us and glaciers will have covered what's available before we even use a notable fraction of one percent. As peat bogs grow, their depth is increased by a paltry 1mm per year, approximately. Based on current harvest rates in North America, peat is accumulating at a rate approximately 70x greater than what is being lost to harvest.
You can probably tell I don't feel guilty about using peat. Peat and coir have moisture retention curves that are close enough you would be hard pressed to say one has much advantage over the other. For this reason, most greenhouse ops that use significant amounts of coir in their media sub-irrigate. Too, one should not think all that needs to be done is substitute coir for peat in container media and all will be well.
Coir is chemically different than peat and requires work-arounds if we are to avoid unnecessary limitations of plant potential. For example, coir is often high in salinity and can contain toxic levels of Na. That said, because they spread so readily, dandelions are a welcome food source in areas where pollen and nectar are scarce. Planting a variety of native perennials with different bloom times ensures that pollinators have consistent access to food.
They also help improve the soil. Their long taproots are a reason gardeners find dandelions so hard to eradicate. However, the lengthy roots are also excellent soil aerators that help loosen up compacted soil. Just the presence of dandelions also alert you to potential problems with your soil, such as infertility.
Yes, you can eat dandelions! Even though they grow so fast, they live for years and their roots grow down as far as 15 feet.
Worse, if the root is cut in half, it clones itself and a whole new plant can grow from just an inch of root left behind. The safest way to get rid of unwanted dandelion growth is to let your grass grow just a bit longer, about four inches tall, to create shade on the lower soil. Dandelions are a symbol for healing, whether from emotional or physical pain, and also surviving hard times as dandelions are the most persistent flower that never gives up.
From making wishes on the dandelion puff to picking a little bouquet without getting in trouble, kids have been using dandelions as playthings for centuries. With their flavorful and nutritious qualities, you could consider them a part of your garden. Dandelions can be eaten in just about any way you can think of. Do dandelions grow at forests?
