Sorry Im not a landscaper so I have no idea what to do. Ive been searching all over the internet for info on this problem but the only information that comes up is 'how far away you should plant trees from your drainfield'. I was in need of some advice on how to remove over growth, small trees(about 2-3ft.in height and the thickness of a cigar) and leaves from the area ontop of my drainfield. I am a mom of 4 with one income and so I want to be able to do this work on my own to save money but I am unsure if that is possible. I know you cant use a backhoe to clear the area due to the drainfields on average only being a couple of feet underground. I also read I couldnt use a rototiller because it could potentially hit the drainfield and I cant use chemicals because it could harm the system...so I dont know what to do. I would like to remove the brush/trees and plant grass seed. Does anyone have any advice on what I can do? I know if I dont get this taken care of while the trees are young I am in for big trouble in the future due to the roots ruining my drainfield.
