Sterile Soil
Hello all.
This is my first time growing heirloom tomatoes. I've been told that I should plant the seeds in sterile soil. But do I need to have sterile soil once the plant get's ready to go outside?
Also, what is the reason behind sowing the seeds in sterile soil? I've been searching for an answer for about 3 weeks now but can't seem to find anything.
