Hi. I have a customer that has about a 3 foot wide "bed" of regular groundcover Ivy in front of her house. The whole bed is about 35-40 feet long. She wants it removed and NOT to come back. What's the best way to do this? I was thinking I would rotortill the bed (I have a large 7.5 hp rotortiller) and use a garden rake to remove all of the choppings of ivy. #1 - How long should this job take? #2- What should I charge? #3- Is this the best, most efficient way to do this? Any ideas #4- Will this pretty much guarantee the ivy won't start regrowing?
