Sun for Dwarf White Pine

(Question)

Hello, I’d like to plant a dwarf white pine on a standard in my front garden as the main specimen. The spot gets full sun from 6am-7am, then filtered light under a maple tree, then again full sun from 1:30pm-4pm before the house shadows it.

I know they prefer full sun, and was wondering if 2.5 hrs strongest sun time, plus another hour of morning is enough? And in winter, it would be essentially full sun from 6am-4pm (after the maple sheds it’s leaves).

Would it survive ok?

Thank you,

“Full sun” is generally considered to mean at least 6 hours of direct sunlight per day, so your garden falls into the “partial sun” or “partial shade” category of 3 to 6 hours of sunlight daily.  Experts agree that, like most conifers, Pinus strobus Nana Group – “Nana” being the dwarf form descriptor – prefers full sun; some nurseries say it will tolerate partial shade; most agree that it requires full sun to be at its best.  It prefers rich, well-drained, acidic soil, and doesn’t tolerate standing water or urban pollution.   Full sun in winter is not as important a consideration for conifers in our plant hardiness zone since they will largely spend the winter months in dormancy.  You may wish to ask the advice of the large nurseries that grow and offer dwarf standard conifers: they should be able to provide their observations of success in a partial shade situation for Pinus strobus Nana.
