Controlling Invasive Chameleon Plant (Houttuynia)

Houttuynia (chameleon plant) is a notorious spreader. Since it grows taller than English ivy, you can selectively wipe glyphosate onto its leaves using a towel-wrapped rake. This targeted application spares the ivy. No herbicide distinguishes between the two plants, so precision is key. Persistence is required—eradication is difficult once established.
