I have just planted about 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 branches seem affected).

A bit of googling left me with more questions than answers. I think
that the problem may be marginal chlorosis, however there seem 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.
