It's certainly a more intense way to go about it than just poisoning Grumpy, and if the option was there, then poisoning is what I would be doing, however considering the proximity of the blackberry's to the house (they make up about a third of the front yard of the house) and the need to have the land cleared in that area to bring power to the house (this one has never been hooked up)there isn't the time to wait for them to disappear, we need the who;e front yard wiped down to lawn height ASAP, which is going to be longer than hoped for since today it is raining!
