has anyone attempted winter-protecting tender trailing berries?
Although *some* trailing berries, like thorny Boysens & a few of the newer hybrids can thrive in colder parts of zone 7 and up, many are not winter hardy even in mild winters - as several posters here have noted in Maryland and similar climates.
However, it seems that, since they are "trailing" by definition, they'd be easy to mulch over winter.
If you let the primocanes trail the first season, then, mulch them somehow, can you overwinter them, then trellis them up in spring?
Has anyone tried this with any degree of success?
My thoguht process is as follows:
Fall - new canes trail along ground. Toss some burlap or thick row cover over them, and pile on some shredded leaves about a foot deep. This should protect them from deep freezes, but still allow gradual cooling (as the ground itself cools) to a point where any required winter chilling could occur.
Spring - around the time of the last hard freeze (low 20s or colder), about late March here, uncover and trellis the canes.
Summer - enjoy your fruit.
Late summer - cut off any spent floricanes after fruiting.
Lather, rinse, repeat.
