What Is It?

Dollarweed is a perennial broadleaf weed with round, coin-shaped leaves on long petioles. It spreads by rhizomes and seed and is most commonly found in poorly drained, overwatered, or low-lying areas of turf. This is a perennial weed. Pre-emergent herbicides do not control existing perennial weeds.
