Good question.
Maybe microelements.

Beware of so-called tree experts who do not understand tree biology.
Storms, fires, floods, earthquakes, and volcanic eruptions keep reminding us
that we are not the boss.

I have four foot Seiryu in its second year in a five gallon clay pot in the
Seattle area.

It browned up in the sun, and so I have moved it to shade, with a board to
protect the pot from the sun, and it is greening up nicely now, but still
no new growth yet.

I plan to move it to a bigger pot this winter.

People say these trees dont need much fertilizer, but I wonder if a little
might help at this point?

If so what sort of fertilizer?

Thanks in advance.
