How to Get Rid of Sticky Willy
Perhaps best known as Sticky Willy, Galium aparine – USDA growing zones 3 to 7 – is an annual plant, largely considered to be a weed. With some basic steps, however, the savvy gardener can effectively remove it from his or her yard. Also known as Goosegrass, Coachweed, Catchweed and Cleavers, it can cause some serious problems for both gardeners and farmers.
Why Get Rid of Sticky Willy?
The sap of the plant can cause severe skin irritation in people who are sensitive to it. If left unchecked, the plant can also severely hinder other plants’ ability to grow. If left unchecked in agricultural operations, the plants can reduce crop yield in some species by between 30 and 60 percent.
The seeds and foliage of Sticky Willy can contaminate the wool and fur of some livestock raised for the production of clothing. If animals consume it, it can inflame their digestive tracts. Its seeds can get stuck in the fur of animals and is very difficult to remove. It can also carry with it different diseases and pests.
Identifying Sticky Willy by Its Small Spines
Sticky Willy is quite easy to identify, thanks to the downward-pointing brown prickles on its leaves – which appear in groups of between six and eight – and stems. Its oblong-shaped eggs have slightly notched tips. Its seed leaves, or cotyledons, are smooth, however. If allowed to mature, Sticky Willy can grow to be 40 inches tall. Large groups of the plants often spread in dense mats over the ground, made all the more dense by their spines. Their flowers are four-parted and often white or greenish-white.
The weed can be found around the world. Most often, Sticky Willy grows in moist and shady areas such as areas filled with waste, on roadsides and in gardens. The species can also affect the growing of hay, rapeseed, sugar beets and various cereals.
Removing Sticky Willy Is Harder Than You Think
Getting rid of a Sticky Willy plant is easy enough; in fact, it’s just a matter of pulling it from the ground. However, each plant can have between 300 and 400 seeds, which spread readily and can lie dormant in soil for six years.
The best way to remove the plants for good is to get them out of the soil before the plants flower and develop their seeds — ideally in the early spring. This can be done using a hoe or another tool that gets to the roots, or by hand. As the plant’s sap is irritating, wearing gloves is an important step if you choose the latter option. If the plant has already flowered, attempting to remove it will only spread the seeds.
Applying a heavy layer of organic mulch or using plastic mulch can also prevent the seeds from reaching the soil or getting enough light to grow.
Gardeners looking to avoid Sticky Willy near their homes should be sure to brush down their clothing and pets after walking in areas where the weed is commonly found, or after exposure. Like most parts of the plant, the seeds are covered in tiny barbs that can stick to cloth or fur easily. The seeds spread easily, and even a few of the hardy seeds can cause an outbreak in a garden.
Chemical Solutions for Galium Aparine
Some herbicides have proven to be effective in removing the pesky plant. Contact herbicides containing acetic, fatty or pelargonic acids can scorch off Sticky Willy’s foliage, including its seed leaves. However, these can damage nearby plants, so covering desirable garden plants is recommended, at least until the chemicals dry on the weed foliage.
Glyphosate can be used in the same way, but it’s more important to ensure none of it gets on any other plants.
