Pokeweed Scouting and Prevention:

The best place to look for Pokeweed is in clearings, woods and along roadsides that have rich, damp soil. It can grow an astonishing 10 feet tall or higher with thin, brown bark on its stem. The leaves are smooth and alternate one another. They are approximately 2 to 3 inches wide and 5 inches long. This weed also produces flowers from July to September; they will appear in clusters with a long stock and a green center with 5 whitish petals. As the plant matures, the round berries will become a deep red or purple.

Pokeweed Control:

To control heavily infested grassland, plowing the soil and planting cultivated crops for a minimum of 2 years after will reduce the growth of Pokeweed. If this is not what you are looking for, then a systemic herbicide will work as well. Due to the complicated root system, the systemic herbicide is used to reach all parts of the plant, including the root system. This particular type of herbicide needs to be applied on the leaves of the plant when the plant is mature and still growing, which is in late summer.
