Invasive of the Week - Japanese Knotweed Popping Up stone.91@osu.edu Thu, 04/16/2020 - 06:31
Often we take notice of invasive plants when they are most obvious - they are in bloom, have put on their yearly growth and are standing tall or maybe wide in some cases, and really can't be missed. But today, I wanted to share an early view of an invasive perennial, Japanese knotweed (Fallopia japonica). That review includes last year's left-overs, hollow stems standling leafless. No new growth will be initiated from these above stems and soon will be masked or hidden by this year's new growth.
