Curly Dock, also referred to as Rumex elongatus, Sour Dock, Yellow Dock, Narrow-leaved Dock – is a perennial broadleaf weed. Preferring disturbed areas, Rumex crispus can be found in bare or thin areas of lawns, meadows, pastures, fallow fields, roadside banks and medians, vacant lots, and along railroads and the edges of yards and gardens. Curly Dock can be found throughout most of North America.
Identifying Curly Dock -
Curly Dock (sometimes “Yellow Dock”) is a taprooted perennial developing a basal rosette of wavy-margined leaves. Its leaves are shiny, progressively becoming more reddish purple in color. Curly Dock features elongated flowering stems that are smooth, ridged and often reddish in color. At maturity, fruit and flowering stems are conspicuously reddish brown.
Blooming from April-May, Curly Dock develops flowers with no petals that are yellow to reddish-green in color and have no floral scent. Reproduction is by seed.
Curly Dock Control -
Curly Dock can be rather difficult to control using cultural weed control methods. It can withstand lawn mowing and large variances in soil moisture. If the weed and its roots are pulled, Curly Dock seeds still can remain viable underground – for more than 50 years.
Scotts LawnService recommends a selective systemic weed control program to fight Curly Dock in your lawn, which ensures the weed control is moved throughout the weed, killing it completely root and all.
