Quizplus · Accepted Answer

Methods A, B, and C (steaming, baking, and using chemical fumigants) are all recognized techniques for sterilizing plant growing mediums to eliminate pathogens, pests, and weed seeds.

Moisture alone, without specific temperature or chemical treatment, does not effectively sterilize soil or growing mediums.
