Purslane is a summer annual, found only in newly seeded or thinning, non-vigorous lawns and sidewalk cracks. It has thick, succulent, rubbery leaves and small yellow flowers. The plant is sprawling and prostrate. It is easily pulled when the soil is moist.
Water, fertilize and mow according to CSU Fact Sheet 7.202, Lawn care, to increase your turf density and make it more competitive with weeds.
Post-emergent herbicide use is more effective when plants are young as purslane is difficult to kill with an herbicide when larger. Always read the label before applying any pesticide.
