My friend Tim Miller is a researcher at Washington State University working to help stop weeds from making life difficult for plants we would rather have. How do weeds grow is the oldest question for many botanists and avid garderners alike, but Green Thumb is going to get down in the dirt and answer the question for you! Your lawn is home to thousands of weed seeds waiting to germinate. Given the right conditions, weeds can easily take over. Find out which areas of your lawn are most vulnerable.
Dr. Universe: Why do weeds grow sooo fast? – Leah, 9, British Columbia
If you’re like me, you’ve picked up a little dandelion fluff ball and blown the seeds around. Weeds like these make a lot of seeds. They get picked up by the wind and planted far and wide. And as you observe, they grow pretty fast, too.
My friend Tim Miller is a researcher at Washington State University working to help stop weeds from making life difficult for plants we would rather have. Sometimes, weeds are bullies to other plants.
“Weeds are simply plants that are able to compete well with the plants we want to grow,” Miller said. “Imagine two plants growing side by side. Let’s say one is a squash and one is a weed.”
He explained that these plants compete for resources both of them need to grow: sunlight, water, nutrients, and space.
“The weed is able to grab those resources before the vegetable plant can get them, so they tend to grow a little faster and a little better than the vegetable does,” Miller explained.
A race to the top
The weed seeds are already in the garden soil. They wait for just the right temperature and moisture conditions. So, when you plant your seeds, the weeds race out of the ground before whatever you planted can even get started.
Sometimes gardeners help their vegetables by growing them in pots and then transplanting them into the garden. That gives the veggie a head start against the weed.
Miller said some weeds grow from a root that has been alive for many years. These kinds of plants are called perennials. The grasses in your lawn are also perennials. Perennial weeds grow especially fast and are much harder to kill than annuals, which have to grow from seed every year.
Perennial roots have lots of energy in them from previous years of growth. Miller explained that energy helps the shoots grow very quickly. This makes perennial weeds particularly hard to control.
Seeds in the breeze
Dandelions are one kind of perennial. Each dandelion fuzz ball has as many as 100 seeds that travel in the wind. If a dandelion plant makes 10 flower heads, that’s 1,000 seeds waiting to sprout wherever they land. How many dandelions do you think you have in your lawn? If there are 50 plants, just think of those 50,000 new dandelions that can sprout from all those seeds. It’s no wonder weeds are so hard to control.
While they may be bullies to plants, weeds have also inspired some interesting ideas. The engineer who invented Velcro was inspired by those prickly weed burrs that stuck to his clothes and his dog’s fur. You never know what might inspire a great idea or when that idea will strike.
How do Weeds Grow?
Weeds live underground and that is where they keep root. Weeds will branch these long veins in the ground and take root based on their seasons. Many common ones up here such as medusaheads and cheat grass are designed to stay hidden and dormant during the winter in order to survive. The idea is that each weed in its part will always be trying to grow.
So if you cut a weed in half and leave it in the ground, it will grow. If you cut of both ends of it and leave a stalk there, it will grow into a new fuller weed.
Weeds grow and eat purely based on the soil and the sun, unfortunately, they don’t need both, they only need one. While they will always grow towards the sun, they don’t require it to survive, which is why we are able to see them in the first place.
So how do you get rid of them?
To answer this question, we have to address the fact that short of completely eviscerating the species forever, it’s impossible. You can get rid of every root in your garden or lawn and if your neighbor doesn’t keep care of theirs, it will grow into your yard.
But in short, you will need to take out every aspect of the roots and seeds in order to get rid of the weeds. This is where the term seed bank comes in. The fact is that weeds have started to realize that we don’t like them in our garden, so in order to survive they have begun leaving their sproutlings dormant all over the place. This means that there will always be the possibility of weeds anywhere.

Why Do Weeds Grow Where They Grow?
Your lawn is an ever-changing, living entity that requires ongoing cultivation in order to remain protected from weed infestation. Any change in a lawn’s environment, structure, or quality can act as an invitation for weeds to take over — and trust us when we say that they will take over without hesitation (and in the blink of an eye!).
At any given time, your lawn may be home to thousands of weed seeds that are eager to germinate. Given the right conditions, weeds will be all too happy to invade your turf. Some of the most common growth areas include:
Anywhere compacted soil can be found
Thinning areas of the lawn
Wet/soaked portions of the lawn
Overly sunny or shady locations
Areas where the lawn meets concrete (e.g. along driveway and sidewalk edges)
These areas are particularly vulnerable to infestation because there is simply not enough healthy, nutrient-rich soil or grass present to crowd out aggressive weeds. Since the majority of local properties feature at least one or several of the problem areas listed above, many homeowners struggle with maintaining a weed-free lawn all year round.
But don’t fret – a lush, uniform lawn structure isn’t a suburban legend. Homeowners can keep weeds at bay and enjoy a pristine yard by following the tips below:
Invest in weed control. Weed Man’s professional lawn care programs include regularly scheduled treatments for control of broadleaf weeds. Weed control works by its ability to mimic natural growth hormones, called auxins, that are found in broadleaf plants. Auxins are absorbed through the leaves of the plants and then translocated to the meristems. Uncontrolled, unsustainable growth ensues, causing the stems to curl-over, the leaves to wither, and eventually resulting in plant death.
Fertilize regularly. A thick, healthy lawn is the absolute best defense against unwanted weeds. This is because a dense turf structure crowds out additional growth, making it difficult for weeds to sprout.
Mow higher. Raise your mowing height. Although many homeowners love the look of a closely cropped lawn, mowing too low can lead to a thin turf structure and cause weeds to creep in seemingly overnight.
Be careful not to over water. Loose, saturated soil can be a breeding ground for weeds. If you’ve seen regular rainfall in your neighborhood, supplemental watering may not be needed.
