weed with white fluffy seed heads

Spotted spurge: Spotted spurge has a reddish purple spot in the center of each leaf and the sap is milky (which may cause a rash in sensitive individuals). This annual weed can be pulled up easily in moist soil. Improving the density of lawn grass can help keep it under control.

Perennial weeds, on the other hand, have more extensive root systems, including taproots, making them more difficult to control. In addition, these weeds come back each year, especially if the roots are not destroyed. Some of the most common (and problematic) perennial weed types include:

Common nettle: This is prolific in soil that borders gardens and open fields. This perennial weed has many varieties, including stinging nettle. While it may look like an ordinary, hairy weed with attractive little flowers, it can cause a very painful sting if you touch it. Nettles can often be aggressive spreaders, with creeping roots.

How to Identify Weed Types

Ground ivy: Also known as creeping charlie, this weed is extremely difficult to control, as this creeping plant (recognized by its round, scalloped leaves, square stems, and small purplish flowers) can form large patches in shady, moist areas of the landscape.

Dandelions: Dandelions are well known in many lawns and gardens– their fuzzy yellow blooms popping up nearly anywhere. While their deep taproots make them difficult to control, they generally spread through their easily recognized white, fluffy seedheads.

Common chickweed: Common chickweed is a mat-forming weed with tiny, star-shaped white flowers. This annual thrives when conditions are cool and moist. Mouse-ear chickweed is similar, however, this weed is perennial with hairy stems and leaves, and is more tolerant of summer heat.

White clover: White clover is a perennial weed that forms creeping runners and produces white, fluffy-looking blooms. Since this weed is a legume which fixes nitrogen, it is often found in lawns with low fertility. Adding nitrogen to the soil can help ease the population of clover.

The white floaties originate from a densely packed seed head that resembles a fuzzy ball. If you look closely, each seed head has dozens of umbrella-like extensions. Located at the seed head’s center are the seeds — each seed has this umbrella structure attached to them. The umbrella’s canopy consists of hairs formed much like a chimney sweep brush. Combining both a tall stem and airy seed head, dandelions keep their seeds upright and available to wind vectors for successful distribution in the region.

Before the specialized seeds appear, dandelions generate a yellow to orange flower on a stem that can rise up to 18 inches from the ground. This flower appears bright and fluffy against its green background, but is not a large or particularly appealing blossom for insect attraction. Requiring no pollinators, dandelions are self-pollinating and often change from flower to seed head over several days. This rapid seeding ability makes dandelions extremely successful at populating a widespread area — gardeners cannot keep up with the constant growth.

The white floaties provide widespread dandelion populations since they fly far distances, especially if the wind is strong enough. In fact, successfully grown dandelion roots help your soil remain aerated. As the roots grow deeply, they reduce soil compaction by creating air and moisture pockets underground. As a result, other tender plant roots have a chance to move into the aerated soil for ample foliage and stem growth. The dandelion taproot also increases nutrients in the shallow topsoil by moving critical elements, like calcium, from the deeper ground regions. Overall, successful dandelion seeds and seedlings create a fertile environment for all plant growth.

Seed Head

Because many dandelions find a good growing location in lawn areas, wind gusts often disperse the seed parachutes throughout the area. The umbrella hairs lift the seed from the head and float along the breeze. The extremely lightweight seed can float as far as the wind allows. Once dropped into another soil location, these seeds do not have extensive dormant periods like other plant species. In fact, the seed germinates quickly to establish itself in the new location before plant competition takes over for natural resources, such as moisture and sunlight.

Enjoying warm locations, dandelions (Taraxacum officinale) grow roots as deep as 15 feet into the soil, if they remain undisturbed. Often considered a weed in lawns and flowerbeds, these rapidly growing plants are hardy in U.S. Department of Agriculture plant hardiness zones 3 through10. The white floaties that the dandelion produces are specialized seeds that are highly successful for widespread reproduction.

In order to keep the seed from growing into mature, seed producing plants you will need to use a preemergent herbicde (that controls broadleaf weeds as well) in the fall. Peremergent herbicide are applied in mid-September and again late winter mid-February).

Please give me a call if you need more assistance (706-295-6210)

Check with a garden centers for preemergent and/or postemergent herbicides available in your area.

Make sure to read and follow all label directions found on the herbicide bag/container. Make sure the herbicide is safe to use on the type of lawn grass which you are growing,

The weed you described seems to be cudweed (without a picture I cannot id with 100% certainty.) Cudweed is a broadleaf weed than does produce a mass of fluffy white seeds. Yes, these seed will most certainly be the next weedy plants.
