Bill, I have been fighting them for years. I used REMEDY for awhile but found that it is too much trouble and cost. I don't want to carry the herbicide everytime I go to the pond. It costs $100 per gallon and once mixed, starts to lose its toxicity. I just keep pulling them up. I have noticed that their root system always angles down to the water. One pond professional told me that a big scenic willow is like having a 2 inch pump running full time. I let them get going on a back pond. They were beautiful. Then the drought hit and I lost 12 to 14 year old catfish. I have noticed while driving around back roads that most dry ponds have infestations of willows, cottonwoods or salt cedars around the banks. Hey, has it rained in North Zulch yet?
