>>951572>>951560German lemonfag here (50°N), my 2 have already grown back almost all of what I pruned away in November, and more branched out at that. Sitting on WSW window in relatively chilly room (15°C-ish at night and in cloudy weather, locally around 20 when the sun's out).
Might have to prune once more before moving them outside (mid- to late April)
