How do I propagate boxwood? Would it be through cuttings? How and when should I do it? I want a low hedge for a perennial cottage garden like I’ve seen in England, but there’s no way I can afford to purchase that many boxwood.
Boxwood can be easily rooted from cuttings nearly anytime with the use of rooting hormones and a high humidity environment. Unfortunately, it would take several years for the plants to reach any noticeable size (the main reason why boxwood cost what they do). For hedges like yours, 1 gallon starter plants should be a cost effective way to begin your hedge, and with much faster results. While boxwood grow well throughout England, one must be careful as to where to plant them here in Michigan. An eastern exposure gives good protection from winter winds and sun, both of which can severely damage the foliage.

Not all boxwood varieties are super hardy or disease resistant. Avoid at all costs the so-called "English boxwood" (Buxus sempervirens 'Suffruticosa'). There are several selections out of the Chicago Botanic Garden ('Glencoe' or "Chicagoland Green", for example).
I take cuttings in August and root them in a cool, humid spot with bright light but not a lot of sun.
One tip: plant boxwood higher than you might imagine — higher than the nursery soil is OK. Mulch lightly, but not up to the stem.
Another great thing about boxwood — deer rarely touch them.
