How to get rid of mullein?
The best strategy is to control common mullein while the population density is low. Plant numbers can easily expand from a few to hundreds per acre in just a couple years due to prolific seed production.
How do you get rid of mullein moths?

It is non–poisonous and you can recognize it from its yellow flowers on the top. Experts recommend pulling it before it produces seeds. Invasive plant species can take over plants that are native to the area. “Mullein is easy to pull.
How is mullein invasive?
Once established it grows quickly to form a dense ground cover. It can overtake and displace native species. At the high densities, it appears to prevent establishment of native herbs and grasses following fires or other disturbances. Verbascum thapsus occurs in areas with an average annual precipitation of 20-60 in.
Why is common mullein invasive?
Mullein is an easy-to-grow plant, often seen growing in fields and ditches. Because of its ease to grow and spread uncontrollably it is considered an invasive weed in many states, including Colorado.
Does mullein come back every year?
Sometimes called verbascum, this group of plants is made up of many different varieties. Most types of mullein are perennials, coming back year-after-year, some plants are biennials and come back for a couple of years, and a few mulleins are annuals.

Use triclopyr if you have desirable plants near or surrounding the common mullein, because this is a selective herbicide that kills broadleaf plants.
What eats common mullein?
It is an easy plant to find, easy to identify and the seeds are easy to collect. However, it is not eaten by all that many animals—some birds and chipmunks eat the seeds. Reportedly elk and white-tailed deer nibble the greens, somewhat.

What is a mullein plant?
Common mullein, Verbascum thapsus, is known by its upright appearance, fuzzy leaves, and yellow flowers. From the Latin “mollis,” meaning soft, even nicknames sound benign: velvet leaf, flannel plant, big taper, cowboy toilet paper. But it’s location, location, location combined with how (seeds) and where (open sites) that elevate it from common weed to invasive plant in 20 states, including Wisconsin, Ohio, Illinois, and all western states. A biennial forb (a herbaceous flowering plant that’s not a grass) native to Eurasia and Africa, common mullein was introduced in the 1700s, and noted in Michigan by 1839.

How big do Mullein flowers get?
First year growth is a rosette of flannelly, oblong, whitish green decurrent leaves (leaves that partially wrap around stems and grow down or along the stems) around 4-12 inches long and 1-5 inches wide , covered in woolly hairs, all anchored by thick, deep taproots.
Can you pull mullein before planting?
Pulling is ideal, especially before the flowers set seed, as the tap root is more easily removed than tap roots of many other invasive plants. Cut, remove, dispose of all obvious flowering parts; avoid disturbing the soil as that’s a certain welcome mat for other mullein plants to grow.
What is Mullein's flow of resources?
In thistle, the flow of resources is directed towards seed development as well. When herbicides are applied, they follow this flow and will not reach the roots.
When to spray for Canada thistle?
For Canada thistle, fall is the most effective time to spray. After the first frost but before it freezes hard enough to kill above-ground leaves is optimal. At this time, plants begin to send their resources down to the roots to prepare for winter.
Management
Prevention is the best and cheapest management option. Having well-established grasses and forbs on a maintained pasture or rangeland with proper grazing and rotational grazing techniques can go a long way to prevent its establishment.
Mechanical Control
Pulling or cultivating small common mullein plants can be an effective control method, as long as the plants are young (before they go to seed). Mowing can be effective to reduce seed production but must be repeated throughout the season.
Biological Control
Consider using biological control insects, such as the curculionid weevil (Gymnetron tetrum) and the mullein moth (Cucullia verbasci). The weevil larvae feed on the seed in the seed capsule and can destroy up to 50% of the seed. The moth larvae feed on the foliage.
Chemical Control
Consider the site, overall weed complex, forbs, shrubs, and trees when selecting a herbicide. Consult the specific herbicide label for recommendations or requirements on the timing of application, amount of water carrier, and herbicide rate and carefully follow all label directions.
What are some alternatives to Mullein?
In the eastern U.S., common milkweed (Asclepias syriaca), butterflyweed (Asclepias tuberosa), joe-pye weed (Eupatorium dubium), black-eyed Susan (Rudbeckia fulgida), and Ironweed (Vernonia noveboracensis), are just a few of the many selections. You may wish to contact your local native plant society for further suggestions.
Why are Mullein plants pulled?
This is an extremely effective method of reducing populations and seed productivity, especially if plant is pulled before seed set. If blooms or seed capsules are present, reproductive structures should be removed, bagged, and properly disposed of in a sanitary landfill. Care should be taken, however, to minimize soil disturbance since loose soil will facilitate mullein seed germination.
How long does Mullein grow?
Common mullein can be found where mean annual precipitation is greater than 3-6 inches and the growing season lasts for a minimum of 140 days. Intolerant of shade, mullein will grow in almost any open area including natural meadows and forest openings as well as neglected pastures, road cuts, industrial areas. Common mullein prefers, but is not limited to, dry sandy soils.
How tall do mullein plants grow?
Mature flowering plants are produced the second year, and grow to 5 to 10 feet in height, including the conspicuous flowering stalk. The five-petaled yellow flowers are arranged in a leafy spike and bloom a few at a time from June-August. Leaves alternate along the flowering stalks and are much larger toward the base of the plant. The tiny seeds are pitted and rough with wavy ridges and deep grooves and can germinate after lying dormant in the soil for several decades.

It quickly spread throughout the U.S. and is well established throughout the eastern states. Records show that it was first described in Michigan in 1839 and on the Pacific coast in 1876, probably due to multiple introductions as a medicinal herb.
Is Mullein a perennial?
Common mullein is a monocarpic perennial (i.e., takes two or more years to flower and die).
