y definition a weed is a plant that is growing in the wrong place. Weeds take valuable space, water, sunlight and nutrients that may otherwise be accessible to important crops, in our case turf grasses. Weeds not only compete for these resources they can disfigure and cause problems to playing surfaces. Weeds are very good
competitors and take advantage of any opportunities to colonise turf situations, particularly when the sward is under stress and weak, leaving bare soil areas for weeds to populate. Weeds have many
mechanisms and characteristics that enable them to do this, having thick waxy cuticle leaves that can be resistant to some chemicals, fast reproduction methods, the ability to reseed in six week cycles and deep tap roots enabling the weed to survive in compacted dry ground conditions. Weeds have one of three life cycles: annual; biennial or perennial.
Annual weeds: Live for a single season. These weeds germinate from seed in the spring or summer, flower and then die.
Biennial weeds: Live for two seasons. During the first growing season, these weeds remain in a vegetative stage and, in the following year, produce flowers, set seed and die.
Perennial weeds: Live for multiple seasons and flower more than once. Perennial structures (rhizomes, stolons, crowns, entire plants or roots) survive from year to year. One perennial weed that evades and colonises outfields and sports fields is White Clover (Trifolium repens). The word Trifolium means three leaflets on each leaf.
White clover is a short-lived perennial that can reseed itself under favourable conditions. It grows rapidly and spreads via stolons. Clover has leaves that are usually palmately to semi- pinnately, divided into three leaflets. The leaflets are entire or shallowly toothed. Stems are low-growing, prostrate, usually without hairs, but sometimes with short hairs, ranging from 100-400mm in height. Stems root at the nodes. The trifoliate leaves and white flowers are both key features that help in the identification of this weed. White clover has a shallow root system, which makes it intolerant of dry soils. It grows best during cool, moist weather on well-drained, fertile soils with a pH between 6 and 7. The clover family has flowers in mostly dense, rounded clusters, with colours ranging from white, yellow, or pink to red or purple. It is fertilised through pollination by insects such as the honeybees and bumblebees.
There are nearly 300 species
