Giant Ragweed control on residential forest & field acreage
Hello, I finally identified my "wicked weed", to which I have a violent skin reaction -- Giant ragweed has taken over the forest edge where my lawn ends. There are groves of it. I read that it is resistant to herbicides. Is it best to cut it off and spray with a spray that will go into the soil? There is a walnut tree in the middle of the stand of weeds. Forest lies just beyond it. I would like to use something organic as a first choice, but understand that may not work in this situation. What can you suggest? Are there weed-control mats I could put down in the spring to control growth next year. Please help! Where can I get the products I will need? What is the recommended method of cutting the weeds down, if that's an option? Thanks, Jan

This plant is an annual, meaning it sets seed in late summer and they germinate next spring. You could put down a pre-emergent herbicide in early spring to prevent the seeds from germinating. If you don't want to apply herbicides, then I would go with mowing a couple of times during the summer. This will prevent the plant from setting new seeds.
