We have a good growing Nandina, well established, about 8 ft after 10 or
so years in ground. It tends to die back a bit in winter -- certainly
all of the new growth it's trying to put on now won't make a really hard
freeze -- but bounce back well in spring. I give it some wood ash each
year and maybe a little seaweed every few years. The exposition is quite
shady and sheltered.

But, I have never seen the berries form well and last through the winter.
They tend to be small if developing at all, then drop off. Currently
there are lots of small red berries but they're clearly in the process of
dropping.

What can I do to get better and longer lasting fruit? Is there a magic
fertiliser that will help?

TIA,
