I read that once temps are consistently below 40F that there are no light requirements for evergreens and that they can be stored in the dark. Is this correct?
My thoughts as well. Hardy evergreens, and particularly conifers, still photosynthesize a bit during the dormant season if the temps are in the 30's ...so they really aren't completely dormant. I kept conifers in an unheated MA garage successfully for a decade, but they didn't go there in until temps outside were consistently falling into the lower 20's every night, and I would let them freeze solid for 3 months every winter. As soon as temps started moderating and the soil and mulch started to thaw, they'd get moved outside. If I were trying to maintain the temp of an enclosure for my trees, I'd shoot for upper 20's to low 30's...frozen trees don't need regular watering and they don't break dormancy during periodic warm spells.Below freezing. ...
Very interesting. How cold?I have evergreens that have been stored in complete darkness for over 20 winters.
Generally around freezing but as low as 10F.Very interesting. How cold?
