Ragweed (Ambrosia artemisiifolia) is a broadleaved, branched annual with compound leaves (divided into leaflets on a single leaf). Leaves are arranged alternately in plant tops, but lower leaves have an opposite arrangement. This weed typically will not germinate after renovation as soil temperatures tend to be too high during July and August.
