Question: I put soil optimizer in flower beds and some lawn about a month ago and the product is still on top of the soil with daily watering. Is this normal? Rick Answer: That is exactly normal and is why applications are needed only every 6 months. OPTIMIZE breaks down very slowly so that the organic compounds are released gradually for about 6-8 months. You should continue to be able to see it for awhile and that is good. It works gradually and for a long period of time.
