How to get rid of dichondra weed?

Dichondra: Ground Cover Turned Weed

Dichondra is an aggressive ground cover plant that becomes a problematic weed in traditional turf lawns. This creeping plant with small, round coin-shaped leaves spreads rapidly through rooting stems and self-seeds prolifically. While dichondra has legitimate uses as an ornamental ground cover in appropriate settings, its invasive spread makes it unwelcome in conventional lawns. Dichondra thrives in moist, shaded conditions common in Charlotte, making it particularly problematic in areas receiving summer irrigation or poor drainage.

Identification and Growth Characteristics

Dichondra's distinctive small round leaves and creeping growth habit make identification straightforward. Unlike true grass weeds, dichondra's broad leaves and sprawling stems are unmistakable. The plant produces small greenish flowers followed by seed pods. Both rooting stems and seed production allow rapid spread, creating extensive patches within a single growing season if left untreated.

Control and Elimination Methods

• Manual Removal: Small dichondra patches can be hand-pulled, though extensive root systems require careful removal to prevent regrowth
• Post-Emergent Herbicide: Broadleaf herbicides containing 2,4-D, MCPA, or dicamba effectively control dichondra. Multiple applications may be necessary for complete eradication
• Smothering: For isolated patches, covering with mulch suppresses growth, though dichondra often regenerates from seed in soil
• Improved Drainage: Since dichondra thrives in moist conditions, improving drainage through aeration and grading reduces conditions favoring establishment
• Shade Reduction: If dichondra occurs in shaded areas, pruning trees to increase sunlight reduces favorable conditions
• Turf Density: Dense turf crowds out dichondra. Overseeding and proper maintenance suppress spread

Long-Term Management

Persistent dichondra control requires continued monitoring and treatment as surviving plants resprout and seeds germinate from soil reserves. Never allow dichondra to flower and seed. Remove plants before maturity to prevent next year's infestation.
