Do you supplement potting soil with another fertilizer?

18 years ago

I know the potting/gardening soils say they will feed the plants for 3 months...does anyone also use miracle grow or bloom booster in addition or would this be overkill? Last year my petunias were strong and healthy until the end of november and I was feeding them once a week, but I can't remember what type of soil I planted them in in the pots :(
