feed for flowering/fruiting plants
I've been reading your article on how best to grow heliotropes. It suggests a feed for them that is heaviest in phosphorous. I always thought that you gave flowering or fruiting plants a feed that was heaviest in potash ?

They are heavy feeders and need both phosphorous and potash as well as nitrogen. Look for a fertilizer with NPK of 10-20-10.
