Put it in whichever window will give it the most bright light for the longest period of time. They may need a period of adjustment, but they like as much light as you can give them.

Direct light, as much as possible, especially during the Winter.

Thank you Josh.

I wrote a reply yesterday, it seems I may never had hit "submit"! I have multiple jades, different types and different sizes, and they all live on a south-facing windowsill, with direct sunlight for 4-6 hours a day. They get a bit red in the summer, but they grow like crazy.

If the plant isn't used to getting that much sun, you have to introduce it slowly, but eventually it will be very happy with a lot of light.

I don't have a south facing window. What would be my second choice? Thanks again.

cadence, in my Zone 5 or 6, my East window gets the most LIGHT, which is second-best to SUN. Some may argue that LIGHT is better than sun. Hope the guys above come back to answer you. I think East is best but I'm not an expert with Jades.

I, too, think East is best...that strong, pure early morning (8 - 11) light. South or West will work. North is more difficult and plants are likely to be sparse and etoliated.

Yes, lots of early morning sun in my east-facing window. That is where I've placed it and so far so good. Thank you everyone for helping me with my newly acquired Jade plant.
