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.


As seeing as they are new to the location and they were just planted, I'd
suggest that you "wait and watch". They may of had some root damage during
planting or may of been begining to need some nutritional supplement from
sitting in the pot for a long time at the store. When plants are in need
of nitrogen, they steal nitrogen from the older leaves and supply it to
the newer leaves. Hence the yellowing. Marginal choloris is more related
to soil ph and potassium deficiency. To prove or disprove marginal
choloris, have the soil ph tested. In general, boxwood can handel a soil
ph of 6.0 to 7.0. If your soil is in the low 6. area, you may want to lime
the soil and fertilize you boxwoods with a high potassium content
fertilizer.
There is also the chance that it could be something else all together.
