It's March, and I'm back to the annual ritual of cutting woody invasive plants to the ground. March, April, and May are "prime time" for a technique called carbohydrate starvation (a.k.a. root depletion). My top target is Japanese barberry at a local state forest where I volunteer. Other bad actors include burning bush, privet, autumn olive, and multiflora rose.
The photo on the right is from the first day of cutting an area three years ago.
