That would depend a little bit on what kind of soil conditioner you are applying and how it instructs you to use it. If its a product that needs to be incorporated into the top layer of soil or applied in any way that would disturb the Tenacity barrier, you would need to have either applied it before the Tenacity, or about 30-45 days after. Tenacity as a pre emergent only lasts about a month in the soil so after that time you could safely apply it if it requires the barrier be interrupted. If its just applied to the top of the soil and watered in, etc you can apply it within a few days of the Tenacity treatment.
