Dandelions fill a field

Dandelion flowers are bright and cheery even if they are a bothersome weed.

Dandelion flowers are bright and cheery even if they are a bothersome weed.

Dandelions are popping up all over in the fields near Viette’s. I guess spring is really here! The sight of these cheery yellow “wildflowers” reminded me of one of my favorite posts on the Viette View’s blog. I am re-posting it today as a fun (and hopefully informative) spring read.

Happy spring – Enjoy!

I was thinking about dandelions the other day – actually I’ve been thinking about dandelions a lot lately. They seem to be everywhere; the ubiquitous lawn weeds! Actually, I think they’re rather pretty – so bright and colorful in the lawn, like an oasis in a giant sea of green! When we were kids, my sisters and I had to go out each spring and dig up all the dandelions we could find in the lawn. “Be sure to get the whole root or it will grow back,” my dad would say! If only they would just bloom and then go away, it would have saved us from a lot of work! But of course they don’t.

Dandelion seed heads are filled with seeds ready to float away on a gentle breeze.

They have the nasty habit of going to seed and then spreading all over the place. First you have a few in the lawn, and then you have an epidemic!

And, what little kid can pass up the temptation of blowing on a dandelion seed head just to watch the little “parachutes” float away on the wind? I know I did it – but it sure annoyed the grownups when I was caught in the act!

So … you have this great idea that you’ll chop the dandelions off with your mower before they go to seed. But, after you mow, they’re still there blooming away in all their golden glory. How very frustrating!

Well, here’s an interesting characteristic of dandelions that I never really noticed before. Have you ever watched the progression of their flowering cycle? When they are blooming, the flower stems are relatively short which keeps the flowers close to the ground. This is especially evident when they are growing in your lawn. Dandelions have developed this clever little adaptation as a defense against herbivory – and what is your lawn mower but a giant mechanical herbivore (in a manner of speaking)! Flowers and foliage that grow close to the ground are less likely to be nibbled off by browsing herbivores/lawn mowers.

In a spurt of growth, the stems carrying the dandelion seed heads shoot upward well above the original height of the flower.

Once the flower closes and the seeds are formed, the dandelion stem undergoes a rapid growth spurt. Seemingly over night, the stems shoot up 2 or 3 times the height of the original flower stalk. Of course this occurs right after you’ve mowed the lawn and the tall, fluffy seed heads rise well above your neatly manicured lawn!

How do they do that?

That’s evolution for you! Survival of the quickest (grower that is)! And there they are, like a bunch of time bombs above your beautiful grass ready explode and spread their seeds with the next puff of wind!

There are products you can use to eradicate these bothersome weeds from your lawn. Pre-emergence weed killers can prevent dandelion seeds from germinating or post-emergence weed killers such as Bonide Weed Beater Ultra or Gordon’s Speed Zone can destroy the weed itself. Bonide Weed Beater Complete and Bayer Advanced Season Long Weed Control for Lawns contain both pre-emergence and post-emergence herbicides. Always read and follow the label directions whenever you use any pesticide!

But before you rid your landscape of dandelions entirely, remember the wise words of Eeyore, “Weeds are wildflowers, too, once you get to know them!”

Until next time – Happy Gardening!
