Money Tree Leaves Curling: Causes and How to Uncurl Them

Money tree leaves curling inward or at the edges? Dry soil and low humidity are the usual causes — but spider mites and cold do it too. Here's the tell for each.

Why Your Money Tree Leaves Are Curling (Quick Answer)

Curling money tree leaves are almost always a moisture message. Most often the plant is too dry — either the soil has gone bone-dry, or the air around it has. A money tree curls and cups its leaflets to shrink the surface area it loses water from, the same way you'd hunch against the cold. Check the soil first: if the top 2 inches are dry and the pot feels light, that's your answer, and a deep soak reverses it. If the soil is fine, the culprit is usually dry indoor air, a nearby heat vent, or the money tree's most common pest — spider mites, which thrive in exactly that dry warmth.

One quotable rule of thumb: on a money tree, curling leaves point away from overwatering. A drowning money tree droops and yellows; a thirsty or dry-air one curls. So if the leaves are curling and the soil is wet, look past water to pests or cold. The full differential is below. Not sure which you've got? Our plant diagnosis tool reads it from a photo, and the general leaves-curling guide covers curling across all houseplants.

Money Tree Curling Diagnostic Chart

The direction of the curl and the state of the soil narrow it down fast.

What you see	Most likely cause	First move
Leaflets curling inward/cupping + dry, light soil	Underwatering	Deep soak or bottom-water
Edges rolling + crispy brown tips, near a vent	Low humidity / dry heat	Raise humidity, move off the vent
Curling + yellow speckling + fine webbing	Spider mites	Inspect undersides; treat
Curling/cupping + tan bleached patches	Too much direct sun	Move to indirect light
Sudden curl + leaf drop after a cold night	Cold draft / shock	Relocate away from cold glass
Curling + wet soil + limp stems	Not curling — it's drooping	See the drooping guide

Cause #1: Underwatering (The Most Common by Far)

Thanks to its water-storing trunk, a money tree tolerates drought better than most houseplants — but push past its limit and the leaflets curl inward and cup as the plant rations moisture. Left longer, the edges crisp brown and, as NC State Extension notes, "leaf drop can occur if the soil is too dry." Curling is the early warning; dropping is what comes next if you ignore it.

The confirmation is simple: the top 2 inches of soil are dry, the soil may have shrunk away from the pot wall, and the whole pot feels noticeably light when you lift it. The fix is a deep drink, not a splash — water slowly until it runs from the drainage hole, or sit the nursery pot in a few inches of water for 20–30 minutes and let it soak up from the bottom. Curled leaves that aren't yet crispy often relax within a day; ones that already browned won't uncurl, so judge recovery by new growth. Then reset the schedule: water when the top 2 inches are dry, which usually means every 1–2 weeks in summer and every 3–4 in winter.

Cause #2: Dry Air and Heat Vents

A money tree can be watered perfectly and still curl if the air is too dry. NC State Extension notes that yellowing shows up "if the humidity is too low," and the same dry air rolls and curls leaf edges before they yellow — especially the tips. The classic setup is a money tree sitting near a heat register, a radiator, or in the path of forced-air heating, where the humidity at the leaf can drop into the teens.

The tell that separates this from thirst: the soil is appropriately moist, but the curling concentrates on the leaves closest to the heat source, often with dry, papery tips. Move the plant off the vent, group it with other plants, set it on a pebble tray, or run a small humidifier — money trees are happiest around 40–60% humidity. Dry air is also the on-ramp to a spider mite problem, so fixing humidity does double duty.

Cause #3: Spider Mites (Check If the Soil Is Fine)

If your money tree's leaves are curling and distorting while the soil is properly watered, suspect spider mites — the plant's most common pest, and one that peaks in exactly the dry, warm conditions that also cause dry-air curling. University of Minnesota Extension notes mites "often become a problem in November when the heat comes on and the air is drier." Their feeding punctures leaf cells, producing fine yellow-white stippling and, as damage builds, curled and distorted leaves with faint webbing on the undersides where the leaflets meet the stalk.

Confirm it by holding a bright light to the leaf undersides or tapping a leaflet over white paper and watching for moving specks. If mites are the answer, start with a hard shower to knock the population down, then two or three rounds of insecticidal soap or horticultural oil a few days apart — the full protocol is in our spider mite guide. Curling from mite damage won't reverse on the damaged leaves, but new growth comes in flat once the colony is gone.

The Other Causes: Too Much Sun and Cold Shock

Two less-common curlers round out the list:

Too much direct sun. Money trees want bright indirect light; NC State warns that direct exposure damages the leaves. In a hot south or west window, leaves cup and curl to reduce the surface hit by the beam, often with tan, bleached scorch patches. Pull the plant back a few feet or filter the light with a sheer.
Cold drafts and shock. A sudden cold night by a drafty window, or the general upheaval of a move or repot, can make leaves curl and then drop. If curling arrived right after a relocation or a cold snap and the trunk is firm, treat it as stress: stabilize the spot, hold off on extra water, and let it recover. Ongoing curling paired with a soft trunk or wet soil isn't a curling problem at all — it's root rot, and you should read that instead.
