Some people in the gardening industry recommend replacing potting mixes every season, but we don’t find that to be necessary. Not only would that be very costly, but it would be inconvenient as well. Where we grow, we fit in 3 distinct crop rotations in per year – spring, summer and fall and we generally use the same potting mix for the entire year. In fact, next year we plan on using the same mix again. I’ll explain how we do it and what we’ve learned along the way.
