When to add preplant mix

Jim,

I cannot remember whether we are supposed to use preplant mix in the
vegetable garden boxes each Spring before we plant new vegetable
seedlings. Thanks ahead for your response.

Pre-Plant Mix is to be added to both containers (Grow-Boxes) and
soil-beds before each crop is planted. In fact, if you plant two or three
crops in the same beds in the same year, you need to apply Pre-Plant each
time.
