Results, cost, health and environmental concerns.
Condo Boards that I have dealt with tend to be politically charged, usually one member has forced the issue of organics & the rest just want the same results at the same price as a chemical program.
Weeds will be your biggest issue as far as results. How will you handle this?
Generally organics will cost more at the beginning. If done properly, after 3 years it can cost about the same as conventional programs and less after 5 years. Make sure you account for lower irrigation costs with an organic program.
Different views on health & environmental concerns can turn into some ugly debates among board members.
