Newbie question: I have the equivalent of 50,000 sq ft of turf to remove and convert to shrub beds at an established apartment complex...... What are my best options? Should I "kill and till" or sod cut and add soil? 90% of these beds will be on flat ground, between buildings and sidewalks. Turf is Bermuda, soil is mainly clay. What equipment will save me the most time getting this done? Never had this big of a re-hab job,,hard to figure time and labor. Any help would be greatly appreciated !!!!
