Habitat & Ecology

Commonly found on roadsides and disturbed areas that are fertile, lime-free and well-drained soils. It reduces yield in pasture and hay lands.

Impacts

It spreads into hayfields and causes baled hay to go moldy because of the succulent leaves.

Management

Small patches can be hand-pulled and best before it produces seed. It is easier to pull small plants because the taproot has not fully developed. Fire, cutting and mowing can reduce seed set but the plants may still re-grow from the root.
