How Fast Do Dandelions Grow After Mowing? Stop Its Spreading

Imagine spending hours mowing your lawn just to find pesky dandelions sprouting up again in no time. It’s a frustrating cycle that many homeowners face.

How fast do dandelions grow after mowing, and how to stop them from spreading? Understanding the post-mowing growth rate of this weed can help you control them effectively.

So, let’s dive in and discover the secrets behind their development.

Once you mow dandelions, they can start growing again after 2 months. If you don’t remove the roots, their seeds scatter everywhere, and you’ll have to deal with them again.

The more you mow, the more they will grow.

So if you ask: does mowing dandelions spread them? I would say 100% YES.

Dandelions are aggressive weeds that can sprout in ten days, making them quite resilient. Moreover, dandelions are an important food source for insects.

Thus, it can be frustrating when mowing dandelions near beehives or other insect habitats.

What Is The Bloom Cycle Of Dandelions?

The bloom cycle of dandelions can be divided into three distinct stages. Each cycle shows the plant’s remarkable ability to reproduce and disperse its seeds.

The Beginning

This stage marks the start of the dandelion life cycle. It begins with the seed stage, where the fluffy, white seed heads are formed.

These seed heads, also known as “dandelion clocks,” consist of numerous seeds attached to feathery bristles called pappus.

When the wind blows, it carries these seeds far and wide, dispersing them to new areas. The seeds have unique structures that allow them to float and glide through the air.

Thus, they can easily find suitable soil conditions for germinations.

Flower Phase

After the seeds have been dispersed, the dandelion enters the flowering stage. A young dandelion plant emerges from the soil, seeking sunlight to fuel its growth.

The plant develops a rosette of leaves close to the ground, absorbing nutrients and moisture from the soil through its entire taproot.

When the plant matures, it produces buds, and vibrant yellow flowers emerge.

These flowers consist of multiple florets and serve as the reproductive organs of the dandelion.

They attract pollinators such as bees and butterflies, which support the transfer of pollen between flowers. It will fertilize them and facilitate seed production.


After pollinating the flowers, they transform into dandelion seed heads known as “cypsela.” Each cypsela corresponds to one of the florets in the flower head and contains a single seed attached to the pappus.

The pappus is a parachute or sail, aiding the seeds in flying in the wind. When the dandelion seedlings mature, the flower stalk lengthens, elevating the seed head into the breeze.

This positioning ensures the optimal dispersal of the seeds over a larger area. The fluffy seed heads, resembling white fluff balls, are a familiar sight in fields and lawns.

Produce Many Seeds

Dandelions are highly efficient seed producers. Each dandelion flower can produce many seeds, ranging from dozens to hundreds.

Unlike fruit or vegetable seeds, dandelion seeds have pappus. This makes it easier to fly with the wind over long distances.

Besides, the light, thin cypsela can easily float till they find suitable soil to grow in. They can also hitch a ride on insects, expanding their growth to new areas.

Thus, they can sprout and establish new dandelion plants easily, increasing the spread of dandelions in an area.

Take The Nutrition From Other Plants

Dandelions can take nutrients from their surroundings, including from other plants. They compete for essential water, nutrients, and light.

Their long tap roots enable them to access nutrients deep within the soil. This makes dandelions more resilient and capable of thriving in diverse environments.

The dandelion taproots tend to take up the space where tall grassroots would have sprouted. It will hinder the growth of the desired plants.

Thus, dandelions can grow rapidly by efficiently absorbing and utilizing available nutrients.

Store The Energy Effectively

Dandelions have a unique capacity to store energy effectively, which speeds up their growth. They store energy in the form of carbohydrates in their strong roots.

The weed accumulates and stores energy reserves during favorable conditions. They usually absorb ample sunlight and nutrients as much as possible.

These reserves provide a valuable resource for quick regrowth and recovery after disturbances such as mowing or natural herbicide applications.

Dandelions can rapidly generate new leaves, stems, and flowers by efficiently utilizing stored energy. This will help accelerate their growth rate.

Get Rid Of The Whole Plant

Does pulling dandelions work? Yes, but you must pull up the entire plant, including its deep root.

Using a garden trowel, dandelion digger, or a weeding tool, gently pry it into the soil next to the dandelion.

Make sure that you extract the entire root system. This method helps prevent regrowth and the dispersal of seeds.

Use Vinegar

Vinegar can be a natural and effective way for dandelion control. Fill Poor white vinegar into a spray bottle and directly apply it to the dandelion plant.

Thoroughly coat the leaves and the base. The acetic acid in this solution works like a desiccant, drying out the plant and inhibiting its growth.

Spray in the morning for 2 days in a row. You will see dandelions, thorny weeds, broadleaf weeds, or perennial weeds around faded and die.

I usually apply vinegar before the dandelions are seeded (I mean before their flowers bloom and fly away) to prevent spreading out to get the best results.

However, remember that vinegar may also affect nearby desirable plants, so apply it carefully.

Spray Them With Organic Weed Preventative

Organic weed preventatives, such as those containing ingredients like corn gluten meal or citrus oil, can inhibit dandelion growth.

These products create a barrier on the soil’s surface, preventing the dandelion seeds from germinating and establishing new plants.

Follow the instructions on the product label for proper application and reapplication intervals.


How fast do dandelions grow after mowing? Dandelions can regrow quickly after mowing, typically within 2 months.

This is because of their ability to produce a wide range of seeds and their efficient energy storage.

It’s best to address the dandelion root system and consider implementing strategies to control its spread.
