I live where the spring temp's are cold the days can be 70 one day or 30 the next day. Does this effect the product? I was told by my extension agency it is better to cut the willows and then right away spray Rodeo on the ends before the cut seals.
If you already have the Rodeo Herbicide you can certainly use that product to kill trees. You would want to use the product undiluted and paint or spray it just as your local agency suggested, immediately after cutting it down to a fresh stump. Depending on the size of the tree and its root system, you may have to do a follow up application after a few weeks. You should not use herbicides when temperatures are near or below freezing; post-emergent herbicides like Rodeo will work best when plants are actively growing.
