Why are my money tree leaves curling?

The 4 most likely causes

The cause of money tree curling leaves usually narrows to one of the items below, ranked by how often we see each in Growli's diagnostic chats. Work down the list — most readers find their answer in the top two.

1. Underwatering or letting it dry too long (Most likely)
   Underwatering looks similar to overwatering at first — both produce limp, dull leaves — but the soil tells the truth. If the soil is dust-dry several centimetres down, water deeply. Money tree prefers when the top half of the soil is dry, every 1-2 weeks.
2. Wrong light level (Likely)
   Money tree tolerates lower light than most, but tolerating is not thriving. In dim conditions it slows down, drops older leaves, and becomes more vulnerable to overwatering because the soil never dries. Give it bright indirect light.
3. Spider mites (in dry indoor air) (Possible)
   Money tree is a spider-mite favourite in dry indoor air. Hold a leaf up to a strong light and check the underside for fine webbing or tiny moving specks. A weekly shower in the sink and raising humidity above 50% breaks the cycle.
4. Cold draught or cold water (Possible)
   Money tree is sensitive to sudden temperature drops. A windowsill that gets cold at night, an air-conditioning vent, or a cold tap-water drench can shock the roots and cause leaves to droop, yellow, or develop brown patches overnight. Keep it away from draughts and use room-temperature water.

Why money tree in particular

Each money tree leaf is a hand of five to nine slender leaflets radiating from one point, and when the plant runs short of water those leaflets fold and curl inward along the midrib to cut their exposed surface. In the dry, heated air of most homes this thin foliage curls well before a waxy-leaved plant would, and it often follows a rootball that dried to the core. Check the undersides too, since sap-sucking mites pucker and cup new growth.

Normal turnover, or real trouble?

New money tree leaflets often unfurl slightly folded and cupped, then flatten as they harden, so curl on the youngest growth at the tip is just expansion. The tell of trouble is mature, already-hardened leaflets curling, curl that persists after a proper watering, or cupping paired with fine stippling and webbing on the undersides, which points to spider mites rather than the plant simply drying out.

How to diagnose in 60 seconds

Run these quick checks before you change anything — the right fix depends on what you find.

• Is the curl upward (cupping) or downward (rolling)? Upward usually = heat or light stress; downward usually = water or pest issue.
• Check the newest leaves first — pests and herbicide damage hit new growth fastest.
• Money tree wants water when the top half of the soil is dry, every 1-2 weeks. Push a finger into the mix and hold it against that: still damp well before it is due, alongside the symptom, is the overwatering signature.
• Check the underside of curled leaves for spider mites, aphids, or thrips with a phone-camera macro.

The fix — step by step

If the leaflets curled because the rootball dried through, a light splash will not reach the roots; give the whole pot a slow, thorough soak until water runs from the base, or bottom-water until the mix is wetted right through, then let it drain. Check the leaf undersides first, and if mites are there rinse them off. Do not answer curl by keeping the soil constantly wet.

This is the recovery sequence Growli walks users through for money tree with curling leaves. Work through the steps in order; skipping ahead is the most common reason a plant fails to bounce back.

1. Identify the curl direction. Upward cupping points to heat or light stress; downward rolling points to water stress, pests, or cold shock. The fix depends on which one you see.
2. Inspect leaf undersides for pests. Hold a phone torch behind a curled leaf — spider mites show as fine webbing, aphids as clusters of green or black dots at the growth tips, thrips as silvery scrapes.
3. Adjust water or microclimate. If the soil is bone dry, soak money tree thoroughly. If the room is below 40% humidity and the species is humidity-loving, add a humidifier. If heat is the issue, move out of direct midday sun.
4. Treat any pests at the source. Rinse pests off in the sink, then spray leaf undersides with insecticidal soap or a neem-oil mix every 5-7 days for three weeks to break the egg cycle.
5. Wait for new growth. Curled leaves rarely uncurl. New growth will tell you if the cause is fixed — if the next set of leaves comes in flat, you have solved it.

When this can't be saved

Most cases of money tree curling leaves are recoverable, but a few red flags point to a plant that has gone past the point of return. If you spot any of these, consider propagating a clean cutting and starting over.

• New growth is thin, twisted, and fern-like (a classic herbicide-damage signature on money tree).
• Curl is paired with mosaic-pattern discolouration — that points to a viral infection with no cure.
• Every leaf curls within 24-48 hours of a single event — usually permanent shock damage.

Prevention

For money tree, the single biggest preventative is matching its native rhythm: when the top half of the soil is dry, every 1-2 weeks, bright indirect light, and a free-draining pot with a working drainage hole. Outdoor edibles benefit from a thick mulch layer that stabilises soil temperature and moisture, both of which reduce curl. For indoor plants, keep a digital hygrometer in the room and aim for 50% humidity — humidifiers or pebble trays close the gap cheaply.
