Almost everyone who buys a fiddle leaf fig, a rubber plant or a weeping fig meets the same thing within a fortnight of getting it home: leaves yellow and fall, sometimes dozens of them on a weeping fig. This is not a disease and it is very rarely fatal. Every leaf on the plant was built for the light level it grew in, and when that light level drops the plant cannot afford to run them all, so it sheds until the number of leaves matches the light it is now getting.
The plant then rebuilds. New leaves that open in your room are built for your room, and those stay. Understanding this changes what you do: the job is not to rescue the falling leaves, it is to hold the conditions steady while the plant finishes adjusting.
| What happened | What the drop looks like | How long it lasts |
|---|---|---|
| Nursery to home | Steady loss of older, lower leaves | Two to six weeks |
| Moved to a darker room | Leaves yellow evenly, then fall | Three to eight weeks |
| Moved next to a radiator or vent | Leaves crisp at the edge before falling | Continues until you move it back |
| Cold draft from a door | Green leaves fall with no yellowing | Stops within days of blocking the draft |
Green leaves falling with no color change means cold or draft. Yellow leaves falling means light or water. The color of the fallen leaf tells you which problem you have.
What to do while it is dropping
The instinct is to intervene, and intervening is what turns a normal adjustment into a real decline. The plant is shedding on purpose and it has fewer leaves than it did, which means it is using less water than it did.
- Do not move it again Every move restarts the adjustment from the beginning. Choose the position on the first day and leave the plant there for at least two months, even if it looks worse in week three than it did in week one.
- Water less, not more A plant with half its leaves transpires about half as much. Keep watering on the old interval and the compost stays wet, which turns light stress into root rot. Check the pot before every watering.
- Do not feed it Fertilizer does not replace leaves and a plant that has stopped growing cannot use it. Wait until you see a new leaf open before you feed again.
- Do not repot it Repotting while it is shedding stacks root disturbance on top of light stress. If the pot really is too small, deal with it after the plant has held the same number of leaves for a month.
How much light each of the common ficus wants
All three of the popular indoor ficus want more light than most people give them, but they differ in how much direct sun they tolerate and how loudly they complain when they are short.
| Plant | Light it wants | Direct sun | How it complains |
|---|---|---|---|
| Fiddle leaf fig | The brightest spot in the house | A few hours of morning sun is fine | Brown patches, no new leaves, bare lower stem |
| Rubber plant | Bright, tolerates a step less | Filtered only, scorches in afternoon sun | New leaves come small and dull |
| Weeping fig | Bright and, above all, constant | Morning sun only | Sheds heavily at any change |
A usable test for all three: hold your hand a foot above the plant at midday. If it casts a shadow with a definite edge, the light is enough. A vague gray smudge means the plant is short.
Temperature, drafts and dry air
Ficus are warm climate plants and none of them handle sudden temperature swings. The problem indoors is almost never the average temperature, it is the difference between the warm middle of the room and the cold pane of glass, or the blast of hot dry air from a heating vent.
- Keep it above 55F (13C) Below that, growth stops and cold wet compost starts killing roots. Under 50F (10C) a weeping fig can defoliate almost completely within a week.
- Find the drafts before you place the pot Stand where the plant will go on a cold day and feel for moving air at ankle height. Entrance halls, the gap under a door and the space in front of an air conditioner are the three positions that cause unexplained leaf drop.
- Keep it off the cold glass in winter A leaf resting on a freezing window blackens where it touches. Pull the plant back into the room at night in winter and return it to the window in the morning, or leave a hand's width of gap all winter.
- Raise the humidity in a heated room Central heating dries the air, and dry air browns the leaf edges of a fiddle leaf fig first. A tray of damp pebbles under the pot or a group of plants together holds enough moisture to make a visible difference.
Turning, and how a ficus grows towards light
A ficus leans towards the light and then stops making leaves on the dark side, and once the back of the plant is bare it takes a long time to fill in again. Turn the pot a quarter turn every time you water and the plant stays even without you thinking about it.
Do not confuse turning with moving. Rotating the pot in the same position changes nothing about the light level and the plant does not react. Carrying it to another room does, and it will tell you about it.
Write down where the plant lives, the date you put it there and roughly how many leaves it has. When it starts shedding six months later you will be able to tell whether anything actually changed, which is the single hardest thing to remember accurately.
When the room is genuinely too dark
A fiddle leaf fig in a dim corner does not adjust and settle. It sheds down to a few leaves, makes nothing new, and slowly hollows out from the bottom. There is no watering or feeding regime that fixes a light problem.
- Move it one step brighter, once Take it to the brightest available window and accept a second round of shedding. One deliberate move to a viable position beats three hopeful moves between dark ones.
- Add a grow light In a room with no useful window, a grow light eighteen to twenty four inches (45 to 60 cm) above the crown for ten to twelve hours a day will hold a rubber plant or a weeping fig indefinitely. Ordinary room lighting will not.
- Choose the plant for the room A weeping fig or a rubber plant copes with a moderately bright room. A fiddle leaf fig really does need the best light you have, and putting it anywhere else is a slow loss.
