How many of you use a two-man treatment crew? Does it work as an efficient system or does it actually eat you in labor cost? Since summer is now here and the heat will be coming I'm wondering in an effort to keep productivity up as well as doing a better quality job, is it worth the investment to bring someone on new to assist on a truck? Figure this would be the best time of year to train new help with insects, weeds, etc.. and yet if you find you don't need them come end of summer then you are at least better off when the fall crunch hits with aerations and other services that need done. Thanks for any input!
