I have trimmed forsythia bushes before, so I know that they are pretty easy. But what my question is how long do you think it would take you guys to trim it when it is about 334' long, I think about 4-5' wide. It's been at least 1 year since it was last trimmed. The one side (161' long) is really overgrown the rest is pretty overgrown. The homeowners usually do these bushes themselves, I think they stand on their Envoy and trim that way...they said it was a little out of their reach now. I think that at its highest point it might be about 10'. And there are also a couple of bushes around the house, no more than one hours worth of work. So this is how I broke it down....just want to see if I am in the right ballpark. Left side bush....161' long x 5' wide x 10' high = about 3 hours back bush.....85' long x 5' wide x 8' high = about 1.5 hours right side......88'long x 5' wide x 6-8' high = about 1.5 hours and one hour for the bushes around the house. then I was figuring on charging either an extra 1/2 hour or hour for going to the job and then disposing of clippings. Also a $30 dump fee. I just wanted to see how long people think they can do this job...I am not sure if I am being unrealistic in thinking that I can do it in this time period or if I am way off. Thanks for all your replies in advance. P.S. I know that your not suppose to trim forsythias till they after they bloom...but if I tell the customer this and they still want it done beforehand, could this possibly harm the forsythia?
