The top organic result for this question, at the time of writing, is a forum thread titled “what are the damned sun requirements for jade plants?” The person goes on to explain the problem: every source says something different, some say direct, some say indirect, and theirs did fine in a bedroom anyway. Twenty people reply and they do not agree either.
That thread is the most useful thing on the page, because it describes the actual situation rather than a recommendation.
Worth a try
It can work here with a little care.
A little dim, but workable
Comfortable temperature
Humidity suits it
Airflow suits it
What a jade plant is asking for
A jade is a succulent from a climate with open sky. In our data its light requirement sits in the highest band we have, the same band as an aloe, and well above the band that a monstera or a pothos sits in. That single fact is doing all the work in the table below, and it is the fact that most care articles skip, because the qualitative vocabulary does not have a word for “more light than a window can supply.”
Everything else it wants is easy indoors. It is comfortable across a wide temperature range, it prefers dry air rather than the humidity most tropical houseplants need, and it does not mind normal room airflow. In the scoring below, temperature, humidity and airflow are all held at the plant’s own preference so that the only thing changing between rows is light.
Nine spots, scored
These are indoor spots at typical clear-day conditions. Read the last two columns rather than the lux figures, which look generous right up until you see what the plant does with them.
| Spot | Estimated light | What the light is doing | Verdict |
|---|---|---|---|
| South sill, against the glass | 13,000 lux | A little dim, but workable | Worth a try, 68/100 |
| 1 m in from a south window | 10,000 lux | A little dim, but workable | Worth a try, 67/100 |
| 2 m in from a south window | 6,300 lux | A little dim, but workable | Worth a try, 65/100 |
| 3 m in from a south window | 3,969 lux | Too dim here | Not the best fit right now, 46/100 |
| West sill | 7,800 lux | A little dim, but workable | Worth a try, 66/100 |
| East sill | 6,500 lux | A little dim, but workable | Worth a try, 65/100 |
| 1 m in from an east window | 5,000 lux | Too dim here | Not the best fit right now, 46/100 |
| North sill | 3,640 lux | Too dim here | Not the best fit right now, 45/100 |
| 3 m in from a north window | 1,111 lux | Too dim here | Not the best fit right now, 45/100 |
Not one row says the light is right. On our snake plant page a table built the same way produces the opposite picture, so the clearest version is to walk both plants down the same window:
| Distance from the glass | Sunset jade | Bird's Nest snake plant |
|---|---|---|
| 0.3 m against the glass13,000 lux | 68/100 | 67/100 |
| 1 m back10,000 lux | 67/100 | 68/100 |
| 2 m back6,300 lux | 65/100 | 68/100 |
| 3 m back3,969 lux | 46/100 | 100/100 |
Same window, same four readings, so the windows are not what changed. The plant is.
Why “a little dim” at thirteen thousand lux is not a mistake
Thirteen thousand lux is a lot of light by indoor standards. It is exactly double what the east sill in the same table gives, and more than ten times what three metres into a north room gives. Called dim, it sounds like an error.
It is a comparison to the wrong thing. Full daylight outdoors runs into six figures. A south-facing pane on a clear day passes a fraction of that, and a plant evolved for open sky reads the difference immediately. It is saying that for this particular plant, the brightest position in the house is still on the thin side, which is exactly why jade plants indoors tend to stretch, lean toward the glass and lose their compact shape rather than die outright.
If your own jade is doing that, the diagnosis is usually not watering. Our page on why a plant leans to one side covers the mechanism, and it is the same one at work here.
Why every source says something different
Look at what the published advice claims, and at what each claim leaves out:
- “At least four to six hours of light daily.” A duration with no intensity attached. Four hours on the north sill and four hours on the south sill differ by more than three times, and both satisfy the instruction.
- “Bright indirect.” A category with no distance attached. Measured on the sill, or three metres back?
- “Direct sun.” The opposite instruction, for the same plant.
- “Mine lives in a bedroom and is fine.” An outcome from one room nobody else can see.
Every one of those is describing a different threshold, and none of them says which one. The reason the argument never resolves is that the participants are answering two different questions at once: whether a jade will stay alive somewhere, and whether it will actually do well there. A jade is a succulent with water in its leaves and a slow metabolism, so the survival answer is generous and the thriving answer is strict. Both camps are telling the truth about their own question.
Numbers do not settle the argument by themselves, but they do separate the two questions. Everything in the nine-spot table is somewhere between survivable and comfortable. Nothing in it is thriving.
How much of this is the plant rather than the house shows up when other plants stand on that sill. The reading does not change. The complaint does:
| The plant on the sill | What the light is doing | Verdict |
|---|---|---|
| Sunset jade | A little dim, but workable | Worth a try, 68/100 |
| Aloe vera | A little dim, but workable | Worth a try, 68/100 |
| Fiddle leaf fig | Just the right amount of light | Good fit, 85/100 |
| ZZ plant | A bit bright, but workable | Worth a try, 67/100 |
| Monstera | A bit bright, but workable | Worth a try, 65/100 |
| Golden pothos | Too bright here | Not the best fit right now, 44/100 |
Four of the six land in the sixties while asking for opposite corrections: the jade wants the light stronger, the ZZ plant and the monstera want it softer. The score alone does not tell you which.
So what do you actually do with one
Give it the brightest window you have, put it on the sill rather than back in the room, and accept that indoors you are growing a slower, softer version of the plant than the one in the photographs.
The gap between those two plants is not a matter of degree, and it is the one thing on this page worth scoring rather than asserting:
| Where it is standing | Estimated light | Verdict |
|---|---|---|
| Indoors, at the window | 13,000 lux | Worth a try, 68/100 |
| On a balcony | 45,000 lux | Great fit, 100/100 |
| Outdoors, in the open | 80,000 lux | Great fit, 100/100 |
A pane of glass is most of the difference. The brightest spot in the house is a third of what the same sun delivers on the other side of it, and that third is the whole reason every indoor row on this page reads dim.
If you want the compact, red-edged, thick-stemmed jade, that plant lives outdoors for at least part of the year, and there is no arrangement of indoor furniture that substitutes.
Two of our pages take a jade through a single window in more detail, one for a south-facing window and one for a north-facing window, where the answer is the same at every distance. If you would rather check the spot you actually have, the free spot checker reads it in your browser, and you can lay the phone down at the exact place the pot would go.
About this article
The lux figures are our estimates for indoor positions on a clear day, and the verdicts come from the same scoring the app uses. In the nine-spot table, temperature, humidity and airflow are held at this plant’s own preferred midpoints in every row, so light is the only thing varying. Where a table puts several plants in one spot, those three are held at one set of values and the caption prints them.
Not here: we have not measured a jade’s growth, so nothing above says how fast yours will grow. Scores on our other pages may differ by a point or two for the same window, because those declare real weather rather than midpoints.
