>>960727>>960728German here, I have mine sitting inside from Oct-Apr on a WSW window, in summer outside in full sun.
We're not really getting more sun than England especially in winter, but still they've not become particularly leggy so far, what helps is having them sit in a room where it's mostly ~15°C, and only locally warmer whenever the sun is out and shines upon the black pots.
Mine sprouted Jul 2015 and I think the first branching occured somewhere around Apr/May 2016 (without prior pruning).
I only pruned them when I brought them inside for winter last November, but they've already regrown all that and then some
The very oldest leaves at the bottom are partially yellowing and a few have dropped off now, but I'm not too worried as I blame general winter stress and the fact that even an evergreen's leaves aren't staying on forever (unless maybe on a Welwitschia)
