Today in the Garden of a Lifetime: Coat-racking the Korean Pines

Plant anything fifteen years ago, and it should be a lot bigger by now. Compact and upright though they are, these two Silveray korean pines flanking the grassy alley are finally too broad as well as tall. What's needed is more than snapping off much of the soft new growth, the "candles," each May. That only slows the increase in size.

Plus, as the tree slowly continues to expand, the new growth becomes denser and denser as side-candles—the secondary candles in each "candelabrum"—account for more and more of each season's growth. Over a decade and more of such incremental attention, each of this pair of Pinus koraiensis 'Silveray' has still become too large, just more slowly. And they are both unusually dense as a result.


What's needed is more than snapping off much of the candles each May. Instead, it's time for "coat-racking"—cutting all the branches back as far as possible, leaving only crude, projecting stubs: the hang-your-hat-on hooks of the "rack." I do this every few years with my massive hedge of American holly, which—typical for all hollies—branches almost as readily from stubs of remaining young growth as directly from even the oldest trunks.


Few needle conifers—and no pines—are as accommodating: Only yew (Taxus) and Chinese "fir" (Cunninghamia) can resprout from old wood. (Fan-spray conifers—think arborvitae and Hinoki cypresses—are a bit more willing.) If any given branch of a typical needle conifer isn't to remain a leafless stub forever, it can be "racked" back only as far as its closest-to-the-trunk needle-bearing growth. 


Even so, the amount of the canopy that can be removed from these Korean pines is striking. In the picture below, you can see that the right-hand pine is now less than half as wide as the left—and after just five minutes of fearless pruning.

Five minutes later, the left pine is also shorn.

Coat-racking isn't done for the subtlety of the close-range view: The stub-ends of the severed limbs are shocking.

But looking through the other end of the telescope, you realize how much needle-bearing growth remains. New candles will emerge from it spring into summer; I'll post or Instagram showing the progress.
