For a small fee, I can smuggle you 7 bloody goats of various sizes and aggressiveness. They eat anything, including tarmac if the number of times they squeeze out of their field to wander up and down the lanes and terrify innocent hackers is anything to go by lol!
Cut them back, let them reshoot and then spray them with something like 'Broadshot, Roundup (generic glycogen) or Garlon' it will take more than one hit but if you keep cutting back the regrowth and spraying you will eventually exhaust and kill the root system. Ring an agronomist for advice.
Oh rats BumpyRide. Was hoping you'd take me up on my offer. What am I supposed to do with the 7 bloody goats crammed in the boot of my car???????????????????????????
