SpurgeWith hot and dry weather that we encounter in July and August in Oklahoma, a common summer broadleaf weed named Spurge makes its’ presence known. It can not only grow in lawns, particularly well along the edge bordering the street, but in landscape beds, small cracks in driveways, etc. It does not take much soil for Spurge to germinate in and grow, with its’ deep taproot sinking down wherever it can find a place to grow. It is well adapted to hot, dry, Oklahoma summers with thick fleshy leaves holding the water in the plant well. From one taproot, spurge can spread out like a mat into the lawn or shrub bed. The good news is that it’s easy to pull up. And since our broadleaf herbicides are not as effective when temperatures are over 90 degrees, this is really the best way to eradicate it. With the thick, waxy, and small leaves, it’s difficult for a broadleaf herbicide to adhere to the leaves and be absorbed for good control.

Spurge is one of those broadleaf weeds which the early spring pre-emergent really does not control much. It will help some, but spurge is just going to germinate during the summer.  Our Bed Weed-Control Program, with special pre-emergents applied in early spring, will actually control spurge better than our lawn pre-emergent, Barricade.  So with this troublesome summer weed, one will have to go “old school” some and hand pick the weeds in most cases.
