Does seed start mix benefit from adding anything for flowers?
I have a terrible history growing flowers from seed. It only works about 20% of the time for me.
I'm looking to grow a lot this year and am starting with a seed starting mix. I'm wondering if flowers would benefit from adding anything to the Jiffy mix (such as blood or bone meal, worm castings, an over all plant food like espoma plantone, etc)?
Thanks for the advice.
