I have a pond that is 4 years old now. Each year the Black Willows keep getting bigger and bigger. Each year I use my pole saw to cut them back to the base, and I clean the pond edge all the way around.
How do I KILL these blasted willows? Last year I tried burning them with a propane torch. That didn’t work. I don’t know what to do. But I HATE them.
I am going to try and post a picture, but i don't think i will have much luck.
Best way I've found to kill them is cut them flush to the ground in the Fall and immediately paint Tordon RTU on the cut stump. I have some in a small coffee can, and use a 3/4" or 1" wide "chip" brush that you find in the paint dept at the big box stores. The brush is typically under a buck and is of natural hair, steel clamp and a wooden handle. I pour about 1" in the bottom of the can, and leave the chip brush in the can (with the lid on) as I move it around. I waste less brushing it on vs. squirting it on.
