Spotted spurge is a weed that starts to make it's presence known in the hot weather of July. It grows anywhere; in lawns, flower beds, and loves the cracks of walkways.
This spurge is a low growing annual that forms large dense mats. The leaves are small, oval shaped with purple markings. The stems are reddish which when broken ooze a white sap. Pinkish-white flowers produce seed until October that easily survive the winter to germinate the following season.
You have to stay on top of this weed. Spotted spurge produces a lot of seed and spreads quickly. It forms seed when it is only two weeks old!
In lawn situations you have to use a selective chemical weed killer to go after spurge since no organic product is labeled for it. Prevention is the way to go with this weed. Again a chemical pre-emergent would work better than an organic one. When it is growing in a flower bed or in the cracks of walkways, you do have some options. An organic non-selective weed killer (meaning it kills all vegetation) such as Burn Out can be employed, or a chemical one such as Round Up can be used as well.
