My question has sereral parts to it. First I recently recieved a brochure from Plant Health Care.com. They offer products like Tree injectables that contain mycorrizial fungi and VAM fungi to help trees. Has anyone had good results with this companys products. They seem laget but I know that some think of it as smoke and mirrors. Secondly, if you do use it, what is a resonable rate to chare for applications. One box of 4, 8oz pakages is good for 800 injections. At $148.00 a box I need baseline for pricing. Thanx for your help.
