People hate chemicals. I get it. But sometimes, you need the big guns. Glyphosate is your frenemy here. The trick is timing.
You don't spray in spring. Bamboo is too happy then. It’s like trying to knock out a boxer who just had a nap. Wait for late summer or early fall.
Why? The plant is storing energy for winter. You spray the leaves. The poison rides that sugary elevator straight down to the rhizomes. Boom. Suicide by snack.
You’ll need to cut the stalks first. Then spray the fresh cuts. It’s like a vampire’s worst nightmare. Messy, but effective.
