Pines that require "full sun"

12 years ago

I planted a pinus bungeana this summer in a spot that gets at least 7 hours of sun....in the summer that is. I failed to account for how low the sun gets in fall and winter. It will only get an hour at most of full sun late in the day during the winter.

Should I move this or will it be OK as long as it gets plenty of sun during late spring and summer?

Thanks

    Main thing is to make sure there are no trees or buildings overshadowing it, it will grow away from them and become deformed.

    The low angle of the winter sun on an otherwise open, uncrowded position should have no effect.

    hey jim.. talk to me about your utah ...

    does your soil freeze ... if so.. and the plant is in total complete dormancy ... then we would have to ask ... what does it need sunshine for ...

    as compared to say.. bboys PNWest bare dormancy ...

    also.. what produces the shade ... keep in mind.. if it is deciduous trees... they will be losing their leaves soon ... and though sun thru bare trees is not quite full sun ... its better than a sharp pine needle in the eye ..

    being as lazy as i am ... i wouldnt move it again ...

    The soil freezes a little on top sometimes although much of the winter it is insulated by snow.

    The shade is from the neighbors house to the south. It's not that close to the house but the house is tall enough to block the sun when it gets lower in the sky.

    I would say it would probably emerge from the shadow around mid-April. I'm leaning towards moving it because it's just a little guy. Not much more than a foot tall.

    it would probably emerge from the shadow around mid-April.

    ==>>>t hen the question is... when will the buds elongate ...

    for me in my MI ... it would be mid to late may ... by which time the plant would be back in sun ...

    yes .. at one foot.. now is the time to move it ...

    This is my first experience with a bungeeana but I know the buds on my ponderosa, strobus, heldrechii and nigra elongate before that here. The more I think about it it's definitely time to move it.

    In temperate climates, conifers don't require much (or any) direct sun while they are dormant.

    If you were in a Mediterranean or sub-tropical climate when winter can be a time of active growth, the lack of direct sun would be a problem.

    My only worry is that it might be in the shadow a bit too late in the spring. I think I'll do the safe thing. I should have thought of that this summer when I planted it.

    Winter sun isn't an issue in cold climates, so don't worry.

    Table Mnt pine (P pungens) is notorious for needing nearly full sun or it gets stunted. Mine gets 6 hrs, and that's just enough to keep it happy, tho it would grow faster w/more sun.
