Probably needs more phosphates. Nitrates the first number in a
fertilizer produces lots of green. That is why lawn fertilizers have
a higher first number, but fruits and flowers like a higher middle
number which is for phosphorus. I like a high middle number like
tomato stakes 6-12-6 for flowering plants. I can't always get an
exact 1-2-1 type, but have to settle for something close depending on
the quantity and type I need. The third number in fertilizer is
potash/potassium and plants need a little of that to properly utilize
the other two. I've heard tell that old pecan orchards have been
restored to produce again by the addition of potash.
