A fiddle leaf fig (Ficus lyrata) does best in bright, indirect light, watered only when the top of the mix has dried, and left in one spot. Most leaf drop comes from a sudden change: a move, a draught, a cold or hot blast from an appliance, or a swing between soggy and dry mix.

It is a plant that rewards routine. Pick a position, keep conditions steady and adjust slowly.

How much light does a fiddle leaf fig need?

Bright, filtered light without harsh direct sun. The New York Botanical Garden recommends bright, filtered light and suggests a sheer curtain where needed. NC State Extension notes that afternoon sun can scorch the leaves.

In Australia, that translates roughly as follows:

Situation	What to expect
Near a bright window with a sheer curtain or shade from eaves	Usually a good match
Window that gets hot afternoon sun (west-facing in summer)	Risk of scorched patches; pull the plant back or filter the light
Middle of a room, away from windows	Often too dim; growth stalls and leaves may drop
Dim hallway or corner	Poor fit

The RHS says the plant struggles in low light. Light intensity changes with latitude and season. A spot that suits Brisbane in July can be too fierce in January, and a Hobart window in winter can be too dim. Watch the plant across seasons rather than trusting one placement forever.

How do you stop leaf drop after a move?

Move it as little as possible. The RHS lists frequent moves among the causes of leaf drop. Buying a plant and shifting it between rooms to “try” positions is a common way to lose leaves.

If you must change its position:

1. Choose the new spot carefully first, for light and for air movement.
2. Move it once, and keep the same side facing the light if you can.
3. Expect a few leaves to yellow or drop and then settle. This is not automatically a sign of failure.
4. Resist chasing the problem with extra water or fertiliser.

Avoid placing it in the path of air-conditioning, a heater, or a door that opens to hot or cold air. The NYBG advises keeping it away from heating and cooling units, and NC State links temperature swings near vents to brown spots. In subtropical and tropical homes, the main culprit is often the split-system air-conditioner. In temperate and cool regions, it is winter heating and cold draughts at the glass.

How often should you water it?

There is no reliable number of days. Check the mix instead. The NYBG says to look at how dry the mix is rather than follow a fixed schedule, because humidity and temperature change how quickly it dries. The RHS says to water when the top few centimetres feel dry, and Penn State Extension suggests pushing a finger into the mix or using a moisture meter.

A simple routine:

1. Push a finger a few centimetres into the mix.
2. If it is still damp, wait and check again in a few days.
3. If it is dry at that depth, water thoroughly until water drains from the base.
4. Empty the saucer or cache pot so the roots do not sit in water.

If the mix has pulled away from the pot, Penn State notes that water can run down the gap without reaching the root ball. Loosen the surface gently and water slowly.

Expect the interval to change with the season. Plants in a warm, bright room in summer dry out faster than the same plant in a cool room in winter. Because the plant does not go fully dormant, it still needs some water in winter, just less often.

Why are the leaves dropping or going brown?

Work through the likely causes in order, from most to least common.

What you see	Likely cause	What to do
Lower leaves yellow, then fall	Mix staying too wet	Let it dry further; check drainage; look at the roots if it persists
Dry, crisp edges or limp, curling leaves	Mix drying out too far	Water thoroughly and check the pot is not water-repellent
Sudden leaf drop soon after a move	Change in light or position	Keep it still and be patient
Dark patches near the vent side	Draught or temperature swing	Move the plant out of the air path, once
Pale, dry, scorched patches facing the window	Too much direct sun	Filter the light or step back from the glass
Brown spots that spread, with mushy or foul-smelling mix	Possible root problem	Check the roots; see the repotting section

NC State says both too much and too little water can cause leaf drop, which is why checking the mix beats guessing. Penn State also lists brown spots as a possible sign of root rot, and says to check for pests such as mealybugs, scale and mites. If you find pests, wipe them off by hand or rinse the leaves with plain water. If you think a chemical product is needed, check the product label and your state agriculture department.

Dry air can add to the stress. For more on this, read about what dry indoor air does to leaves.

How do you keep the plant healthy day to day?

• Rotate it. Give the pot a quarter turn each time you water so it grows evenly rather than leaning towards the window. The NYBG and Penn State both advise this.
• Dust the leaves. Wipe both sides with a damp cloth every few months. Penn State and the RHS both recommend keeping the large leaves clean. Clean leaves also make problems easier to spot.
• Feed lightly. In the warm growing months, a general slow-release or liquid fertiliser at label rates is enough. Skip it in winter and when the plant is stressed.
• Check the underside of leaves when you dust. It is the quickest way to catch pests early.

How do you prune it to branch?

A young fiddle leaf fig often grows as a single stem. Pruning is the usual way to encourage branching, and NC State notes that the plant can be pruned as needed.

This part is general horticultural practice rather than something the cited sources test in detail, so treat it as a reasonable approach and not a guarantee:

1. Prune in the warm growing season (spring to early summer in most of Australia), when the plant can recover.
2. Cut just above a leaf node at the height where you want branches to start, using clean, sharp secateurs.
3. Expect new shoots from nodes below the cut, usually over several weeks. Results vary by plant and light.
4. Keep the plant in good light afterwards. A cut plant in dim light will sulk.

Avoid pruning a plant that is already losing leaves from stress. Fix the cause first.

When and how should you repot?

The NYBG suggests keeping it slightly root-bound and moving up one pot size only when roots emerge from the drainage holes. The RHS suggests repotting every one to two years in spring. Those two views fit together: repot when the plant needs it, not on a fixed date.

1. Choose a pot only one size larger, with drainage holes.
2. Use a free-draining potting mix.
3. Keep the plant at the same depth as before.
4. Water well, then return to checking the mix before the next drink.

Repot in spring or early summer so roots can recover. If you suspect root problems, slide the plant out and look. Healthy roots are firm and pale; rotten roots are dark and soft. Trim away any soft ones, repot into fresh mix and water sparingly while it recovers.

Is a fiddle leaf fig the right plant for you?

It suits a bright, stable spot and a person who checks the mix rather than watering on a timetable. If your home has strong air-conditioning, very low light or heavy foot traffic past the plant, a more forgiving species may suit better. The guide to choosing indoor plants for Australian homes compares options by light and care effort. If you tend to forget watering or overdo it, see how a peace lily signals its needs for a different kind of feedback.

What is well established: bright indirect light, drainage and stable conditions. What depends on your home: how often the mix dries, how strong the afternoon sun is, and how much air-conditioning or heating the plant sits near.
