I'm new here and if this topic has already been covered I apologize.
Been growing several tomato plants in containers for many, many years. Some years are better than others as far as results go, as we all know.
Figured I would try Miracle-Gro Garden Soil this year because it was on sale & with rebate ended up being 99 cents a bag (fantastic deal). Got the bags home & noticed they said NOT for use in containers. Great! Rather than haul these things back, would it be ok if I just mixed SOME of this mixture into my containers with the existing soil? I don't understand how any kind of garden soil can be good in the ground yet bad in a container.
What would happen if I filled each container with ALL of this stuff? Would the plants go nuts or die?
Thanks in advance.
