I live in Michigan, and did some online searching; the only place I
could find that had cheap starts (rooted twigs in starter pots,
really) didn't respond to my emails- everyone else is more expensive
that I can afford, or can't confirm their variety. I live in cold
Michigan, so I need to make sure the plants will survive here.

Here's the thing- if I can't find a cheap source (I'll need about 160
plants to grow my wife's hedgerow) then at least I have more time than
money, and maybe I can just grow my own. If I find a boxwood now at
the garden store, and trim every branch and use rooting hormone, and
just try to keep them alive inside over the winter...how long do they
take to root, and what percent of clippings root successfully? Any
tips? I don't mind starting with small plants and taking a few years
to make the hedges, as opposed to buying 1+ gallon pots at several
dollar each.

Thanks,
Keith in Michigan


You will probably want one of the Korean hybrid Box, Buxus microphylla
'koreana', or cultivars which have been crossed/back-crossed with koreana
for cold hardiness. Usually forms a rounded to conical shape.'Wintergreen',
'Winter Gem', and 'Winter Beauty' are crosses or selections of var. koreana
that are quite cold hardy and retain green foliage although sometimes
bronzed or yellowed in winter. Does better in North than South. These
'Winter' cultivars have excellent cold hardiness and fine looks where they
are the only choice in cold areas. Dirr makes these notes about propogation
from cutting:

'Cuttings root readily anytime of year; have had good success with 1000 to
3000 ppm KIBA, quick dip, peaterlite, mist or poly-tent; abundant
literature on boxwood cutting propagation; see Dirr and Heuser, 1987; a
qualification is necessary relative to rooting readily, in actuality they
will root but in our work the 'Green Velvet' et al. series has taken 12
weeks; ideally take cuttings after the growth has hardened in summer.'
