I’ve covered why these plants truly deserve the invasive status. The plan is simple but labor intensive. It is the same as the plan I use to control johnson and crab grasses in the garden and bull thistle in the pasture:
Cut down any growth before it reaches maturity and seeds.
For any plants that spread via rhizomes, green growth like leaves are power plants to fuel root growth. Every time these generators are removed, the roots use emergency stores of energy to reinitiate growth expecting those emergency stores to be replenished by new leaves. If the green growth is continuously culled before it can fuel the roots, energy will eventually run out resulting in the death of these hard to kill plants.
It will take time and labor, but the biological approach to pest control is vital to the success of the farm.
Also I apologize for getting sidetracked over the holiday weekend. I went home to visit with friends and family and explored some of the national park nearby so my attention was elsewhere!
