MaximumYield explains Thug
Thug plants are often sold in garden supply stores and nurseries and are not considered a weed or an invasive species, but nevertheless they can really cause a problem in the garden. A thug plant differs from an invasive species in that they are not a consistent threat in all conditions.
Thug plants include trees and shrubs, climbers, bamboos or grasses, and herbaceous perennials. Popular, pompous grass, and golden rod can all be thug plants given the right conditions.
Some edible plans like blackberry or raspberry can become thug plants if not properly tended.
Control of thug plants varies. Organic control methods including manually digging, pulling, or hoeing them out, and removing used or drying seed heads and old blooms to prevent seeding. Herbicides containing glyphosate are suitable for controlling thugs.
