Thank you for all your responses. Just want to make an informed decision by weighing the cons and pros.
Leslie and Pam, sounds like you have used it for a long time. Larry and Mike, do you use this fertilizer on your flower beds every year? Do you apply it like Leslie's, twice a year? Can I ask how long you all have used it and do you see any effect it has on your soil? Do you see increased earthworm? Does your soil condition improve?
