I prefer to use Milorganite as a mid-late summer application on my lawn. The Fe greens as much as the N in it. I consider it to be organic, just not natural ,which is not the same thing. It takes 3-4 weeks and 2 of rain/water to work. I do not use it on ornamentals.
You may register your phone number online at https://www.donotcall.gov, or by calling toll-free, 1-888-382-1222 (TTY 1-866-290-4236), from the number you wish to register. Registration is free. Thirty days after you register, telemarketers covered by the National Do Not Call Registry must stop calling you.
To prevent this, call 888-382-1222 from your cell phone. This is the national DO NOT CALL list; it takes only a minute to register your cell phone number and it blocks most telemarketers calls for five years. In case you have friends other than me, pass this on to them. [Collected on the Internet, 2005] JUST A REMINDER...
