Do you need sterile potting mixes for growing tomatoes?The answer is yes and no.

For starting tomato seeds, you need a sterile mix. Its job is to give your tomato seeds a safe environment so they can sprout, develop their first couple of sets of leaves, and remain disease-free. The seed itself provides the initial food for the plant, so seed starting mix need little (if any) fertilizer to do its job.

But when you move seedlings to larger pots – or when you plant tomatoes in containers – the potting mix has a different function. It becomes your tomato plants’ home (if you’re growing tomatoes in pots) or at least until they go into the garden (for maturing seedlings.) That means the mix needs to provide both a good home plus food. The best potting mix for tomatoes must contain nutrients in order to grow healthy plants.
