How to overwinter pak choi 'dwarf white stem'

No hardiness zone is recorded for pak choi 'dwarf white stem'; it prefers to stay above about 13°C (55°F) while in growth, so treat it as frost-tender unless you know otherwise for your area. Pak Choi 'Dwarf White Stem' will take cool conditions but not a hard freeze, so the aim is a frost-free winter rather than a warm one. An unheated greenhouse, porch, conservatory or bright garage all work well. Keep it cool, bright and on the dry side, and it will hold steady until growth restarts in spring.

Move under cover before the first hard frost; back outside after the last spring frost.

Water only occasionally — enough that the rootball never dries out completely, no more. No feeding until spring growth begins.

Bringing pak choi 'dwarf white stem' into a warm living room. Too much winter warmth forces weak, pale growth that collapses when it goes back outside — cool and bright beats warm and dim.
