I have recently planted 10 boxwood plants in my garden. The plants are
about 1 -1.5 ft tall.

Soon after planting them, I have realized that about half of them have
a bright yellow margin around some of the leaves (only some of the
branches are affected).

A bit of googling left me with more questions than answers. I think
that the problem may be marginal chlorosis, however there seems to be
*a lot* of possible causes for that.

Living in the Vancouver area, I think we can rule out lack of water as
one of them.
