Weed Spotlight - Spotted Spurge

Tip description
spotted spurge from UMass Extension
This annual weed is native to the eastern US but is now common in home gardens here in California. Spotted spurge germinates at temperatures as low as 60ºF and is often found in open areas, sidewalk cracks, and thin lawns. It forms a dense mat of foliage that grows radially from a central taproot. Left unchecked, each plant can grow to 3' across and can produce thousands of seeds. The seeds need light to germinate, so a 2" cover of mulch usually provides effective control. Pull weeds when you see them, removing the root to prevent regrowth. Use gloves to avoid contact with the white sap which can irritate skin.
