Rough Cinquefoil, also called Norwegian Cinquefoil, is an annual and biennial broadleaf herb that also grows as a short-lived perennial, occasionally. It belongs to the family "Rosaceae” in the Genus “Potentilla”. Rosaceae is the family of Roses as well, which, includes shrubs, herbs, and trees and they're distributed throughout the world. But, Northern Hemisphere dominates these species. Rough Cinquefoil often grows on medium sandy and gravel soils in wastelands, meadows, stream banks, arable fields, gardens, and ornamental landscapes having sufficient moisture at the time of germination. Generally, it succeeds in growing from sea level to 6000 feet above that.
Rough Cinquefoil has its lineages from most of Europe, Asia, and portions of North America. Otherwise, it has cosmopolitan dissemination and is found in every part of the world except for Antarctica. Overall, Rough Cinquefoil belongs to the utmost frugally important family that includes stone fruits, berries, and roses. The pervasiveness to the tropical rainforest and deserts is little restricted due to moisture variation and dry conditions. Besides being a member of an economically important family, Rough Cinquefoil exists as an introduced herb in all states of the US except for North America, where it owns native status. Its occurrence in either side of the Cascades crest in Washington, California to Alaska, and east transversely to North America and the Atlantic Coast are both native and introduced in wastelands and irrigation sources.
Rough Cinquefoil may grow 8-20 inches in height with multiple branching and occasionally give rise to two or more stems from a single root while the stems are throughout hairy. Rough Cinquefoil has compound leaves, which are alternately arranged, and each leaf consists of 3 leaflets at the end of the petiole. Generally, the leaflets are oblong to round having sharp and forward teeth. At an earlier stage of leaflets growth, they resemble strawberry leaves. Flowers are about ¼th of an inch with 5-dull yellow petals. The stamens form a ring with a cluster of tiny pistils that mature to form many clusters of seeds measuring 1/25th of an inch, pale brown or yellow. Flowering occurs in late spring to early summer.
Usually, Rough Cinquefoil sets seeds in late spring to mid-summer. Rough Cinquefoil only propagates through seed, and an individual plant can produce about 13000 seeds. Rough cinquefoil seeds may sprout immediately in Northern Hemisphere whereas, they may be dormant in the southern climate. Seed dissemination takes place in several ways but, precipitation, wind, and pollinators contribute largely in moving seeds to different locations. Rough Cinquefoils can easily pass through the digestive tracts of livestock and birds, remaining viable for several years.
Culturally controlling Rough Cinquefoil involves hoeing, hand pulling, and mowing. Both hoeing and hand pulling are easy when the herb attains 4-5 leaves stage, and Rough cinquefoil is growing actively. Always prefer hand-pulling when there is reasonable moisture in the soil and Cinquefoil hasn't flowered yet. Rough Cinquefoil sets seeds earlier in areas with high surface temperature and low moisture. Feeding the turfgrasses with high nitrogen fertilizers can trigger Rough Cinquefoil growth that delays seed setting. Repeated mowing is also equally effective for controlling them.
Scotts WeedEx Prevent contains 1.71% of Pendimethaline which is a selective pre-emergent herbicide for controlling Rough cinquefoil and many other broadleaf weeds in turfgrasses and garden beds. This product is in ready-to-apply chemistry since it contains a very minute amount of active ingredients and doesn't require further mixing with water. Apply on turfgrasses using a spreader that meets your requirements. The best application time is early spring and autumn. One application may retain its effectiveness for 8-weeks or more. Water your lawns immediately after applying Scotts WeedEx on turfgrasses. Do repeat a second application if needed.
A 10 pounds’ product pack can cover up to 5000 square feet of the targeted area.
BioAdvanced-Lawn Weed Killer contains 2,4-D, Quinchlorac, and Dicamba in the ratio of 4.85, 1.71, and 0.49%, respectively. Their mode of action is both through foliar absorption and roots penetration that clears the Rough Cinquefoil infested areas within 10-days of application. All three ingredients are from the selective herbicide groups that don't harm the turfgrasses when applied over Rough Cinquefoil and other broadleaf weeds.
This concentrated chemistry needs mixing in water before going to the targeted weeds. Add 3.25 ounces of concentrate in one gallon of water and spray on 500 square feet area of turfgrasses. Rain can't waste its efficacy if it comes after one hour of its application. Bermudagrass may show temporary yellowing upon application that would recover after watering. This product is not recommended for applying on centipedegrass, St. Augustine, Bahiagrass, and Floratam.
The active ingredient in Ortho Weed B Gon is 8% Triclopyr that comes in the category of selective herbicides for controlling Rough Cinquefoil and several other broadleaf weeds including, Oxalis, chickweed, Clover, and Ground Ivy. Triclopyr possesses a unique mode of action and pretends to be an auxin that triggers uncontrolled and unprecedented growth in weeds resulting in their death. The hormone itself controls cell division and plant growth and works only on the Rough Cinquefoil and broadleaf herbs when they’re in an actively growing stage. Ortho also offers multiple product chemistry to apply depending on the convenience of the gardeners. A concentrated product usually requires mixing one ounce in one gallon of water that covers about 200 square feet of turfgrasses.
Another option is to connect the ready-to-use formulation with a garden hose and target the weeds which are troublesome for your lawns.
