This perennial weed is commonly found pastures but also invades the garden, growing in the borders and in newly sown lawns. Fortunately it rarely survives the regular mowing of the grass but should be removed when laying new lawns. It is basal perennial with fleshy brown roots that are branched. If a small segment of the root is left in the ground it will regrow so it is best to remove them as soon as they appear.
The main ways to keep weeds under control is constant vigilance, never allowing the weed to flower or set seed.
Remove weeds by hand as soon as you see them. Use a fork so as to avoid chopping the fleshy root up
Regular close mowing of lawns will kill off most infestations
Spraying with weedkiller will do the job if the weeds are in the garden border. Spray with a systemic weedkiller, such as one that contains glyphosate, as this is absorbed through the leaves of the plant and the active ingredient makes its way through the cells of the plant down to the root. It kills these first and then the foliage starts to die off
Mulching will help to eliminate light, which all green plants need to survive. There are several effective mulches which will act as a weed barrier; weed suppressing fabric, well-rotted manure or garden compost, bark, grass cuttings, gravel and even a thick layer of newspaper
