Today I am spreading iron sulfate made in Mo. Hope it will knock out the moss. Then another 800 lbs of lime (calcium carbonate) trade name Calpril. The lawn pro is coming back to rip up the front 1/3 acre which was weeds. I felt for the guys who soaked that area with Roundup ( I fought doing this for 3 years). The stench was almost nauseating for a couple days. The backpack sprayer I used to use for Cross Bow put out a fine mist. These guys saturated the ground. Many people hate Montsanto . This week someone said Roundup is carcinogenic. If so the guys should wear organic cartridge masks . I wanted to spread clear plastic sheet and let the sun kill the weeks, but pricing was prohibitive and keeping the stuff in place seemed impossible. :confused2:
