Hey this is an area that I could use some help with. I know many of us have clients that want us to Fert/ bug spray. I have in the past done it as labor if they buy the bag and leave it. this season most of my clients want me to keep up a fertilizer plan, usualy I just politly tell them to call a local company, however this year was about 60 % asking for me to do it next year. Should I spend the time and get cert. and insured or just sub out and add a % (10-15)to the price I pay to sub? Is it worth it to spend the time and the money to get cert or just be better off having a local guy do it? Thanks for any help.
