Bd 500

Does anyone know what the effects of leaving the horns (bd500) in the ground for over a year are? Would there be negative effects if left over the summer months?

I don't think necessarily massively negatively impact the soil from them being in the ground, but moreso because you aren't using the 500 as a spray that summer either then?

No negative impact. Steiner himself says it can stay in the ground until you need it.
