When a money tree starts dying, the most likely cause is soggy soil and the root rot that follows.
Most dying money trees are suffering from overwatering or poor drainage, which rots the roots so the plant can’t take up water, and that shows up as yellow, drooping, falling leaves and sometimes a soft trunk. Dry soil, poor light, cold drafts, dry air, too much fertilizer, and pests cause the rest.
The good news is that a money tree (Pachira aquatica) is tough.
It comes from the wetlands of Central and South America, stores water in its trunk, and can regrow leaves from bare stems if the roots and trunk are still firm.
Once you can read the symptoms, you’ll know which fix to make first and which ones to skip.
Check the Leaves, Trunk, Roots, and Soil First
A five-minute inspection tells you more than any guess. Leaf color points you toward a cause, and the firmness of the trunk and roots tells you how serious it is. If you are stocking up, a soil moisture meter is the first thing I would pick up.
What Do Yellow, Brown, Drooping, or Falling Leaves Tell You?
Each symptom has its own short list of suspects. I’d match yours to this table before changing anything.
| What you see | Most likely causes |
|---|---|
| Yellow leaves | Overwatering, poor drainage, low light, or old lower leaves aging out |
| Brown, crispy leaves | Underwatering, low humidity, sun scorch, fertilizer salts |
| Curling leaves | Underwatering, dry air, heat, too much light, pests |
| Drooping leaves | Too wet or too dry, so check the soil |
| Leaf drop | A recent move, drafts, sudden light change, over- or underwatering |
| Soft or mushy trunk | Rot |
One yellow leaf at the bottom of a healthy money tree is normal aging. Several yellow leaves at once, especially with wet soil, is a warning. My guide to money tree leaves turning yellow goes deeper on color patterns.
How Can You Tell Whether the Roots and Trunk Are Still Healthy?
Squeeze each trunk gently from the soil line up. A healthy trunk feels firm like a carrot, while a rotting one feels spongy, wrinkled, or hollow.
Then slide the plant out of its pot. Healthy roots are firm and white to tan.
Rotted roots are brown or black, mushy, and they smell sour. Also push a finger 2 inches into the soil: if it’s wet and the plant is wilting, skip the watering can.
Overwatering and Root Rot: Check These First
Overwatering kills more money trees than anything else. Soggy soil pushes out the air roots need, they suffocate and rot, and the top of the plant collapses even though it’s sitting in water.
What Does an Overwatered Money Tree Look Like?
An overwatered money tree has yellowing leaves that droop and fall while the soil still feels damp days after watering. Watch for these signs:
- Yellow leaves starting low on the plant and moving up
- Soft, drooping leaves even though the soil is wet
- Brown, mushy spots near the base of the trunk
- A sour or swampy smell from the pot
- Tiny flies (fungus gnats) hovering over the soil
The usual culprits are watering on a calendar, a pot with no drainage hole, a decorative cachepot holding runoff, or a saucer left full of water.
How Do You Treat Rot and Fix Poor Drainage?
If the roots are mostly firm, stop watering and let the top 2 inches of soil dry. Empty the saucer and move the plant to brighter indirect light so it uses water faster.
If you find rot, act the same day:
- Remove the plant and gently shake or rinse off the old soil.
- Cut off every soft, dark root with clean shears, wiping the blades with rubbing alcohol between cuts.
- Repot into fresh, well-draining potting mix in a clean pot with drainage holes.
- Water lightly once, then wait until the top 2 inches dry before watering again.
For the mix, I like a peat- or coir-based potting soil with perlite and pine bark added. My guide to the best soil for a money tree has the ratios.
Keep the new pot only 1 to 2 inches wider than the root ball, since extra soil stays wet longer.
Underwatering: When Dry Soil Causes Drooping
A thirsty money tree droops too, but its soil is dry and its leaves turn crispy. This happens most in summer, in hot rooms, or when a plant gets forgotten for a few weeks.
How Can You Tell Thirst from Root Rot?
Feel the soil and lift the pot. Dry soil that’s pulling away from the pot’s edges, plus a pot that feels light, means thirst.
| Sign | Underwatered | Root rot |
|---|---|---|
| Soil | Dry, hard, shrunk from edges | Wet or soggy |
| Leaves | Brown, crispy, curled | Yellow, limp |
| Trunk | Wrinkled but firm | Soft or mushy at the base |
| Smell | None | Sour |
A thirsty trunk can look shriveled because the plant is drawing on its stored water. It firms up again after a good soak.
How Should You Rehydrate a Dry Money Tree?
Bottom-soaking is my go-to fix, because bone-dry peat and coir shed water from the top. Set the pot in a sink or tub with 2 to 3 inches of room-temperature water for 20 to 30 minutes, then let it drain completely.
After that, water when the top 2 inches of soil feel dry. Indoors that’s about every 1 to 2 weeks, and less in winter.
My guide on how often to water a money tree covers seasonal timing. Expect leaves to perk up within a day or two, though crispy edges stay brown.
Light Problems: Too Little Light or Scorched Leaves
Money trees grow best in bright indirect light and tolerate medium light. A dark corner starves them, and hot afternoon sun burns them.
What Are the Signs of Insufficient Light?
A money tree in insufficient light grows slowly and stretches. Look for:
- Stems leaning hard toward the window
- Long gaps between leaves and smaller new leaves
- Pale, light green foliage
- Older leaves yellowing and dropping
- Soil that stays wet for more than a week after watering
That last sign links low light to root rot. A plant that isn’t photosynthesizing much doesn’t drink much, so dim rooms and overwatering go hand in hand.
Winter makes this worse across the Northeast, Midwest, and Pacific Northwest, where short gray days cut indoor light sharply.
Where Should You Place the Plant to Avoid Sunburn?
I’d put a money tree right beside an east-facing window, or 3 to 5 feet back from a south or west window, or behind a sheer curtain.
Gentle morning sun is fine; direct afternoon sun leaves pale tan or brown patches on the leaves facing the glass.
Rotate the pot a quarter turn every week or two so all sides get light. If you’re moving it into stronger light, do it over 1 to 2 weeks, since leaves grown in shade burn easily.
Scorched spots won’t turn green again, but new leaves will grow in clean.
Cold, Drafts, and Heat Vents
Temperature swings are a common reason a money tree suddenly drops leaves. It’s happiest between 65 and 80°F and gets hurt below 50°F.
Can a Cold Night or Draft Trigger Leaf Drop?
Yes. A plant beside a drafty door, a cold window pane, or an AC vent can shed leaves within days. A money tree left in a car or on a porch on a chilly night often wilts, and severe cold turns leaves black and mushy.
Heat vents and radiators cause trouble too. Blasting hot, dry air crisps leaf edges and dries the soil fast.
How Should You Adjust Its Spot for Winter?
Before the furnace kicks on, move your plant at least 3 feet from heat vents, radiators, and exterior doors.
Pull it back a few inches from the glass on frosty nights, since windowpanes in the Northeast and Midwest get cold enough to chill leaves touching them.
Money trees live outdoors year-round only in USDA zones 10 to 12. Everywhere else, a plant that summered outside in shade needs to come in before nights drop below 50°F. Water less in winter, because cooler rooms slow growth.
Low Humidity and Crispy Leaf Edges
Dry indoor air browns the tips and edges of money tree leaves first. The plant does best at 50% humidity or higher but tolerates average home levels, which in heated winter homes can fall well below that.
How Can You Tell Dry Air from Dry Soil?
Check the soil first. If it’s evenly moist and only the very tips and margins are brown and papery, dry air is the likely cause. If the whole leaf is limp or curled and the soil is dry, the plant needs water.
Humidity damage shows up most from November through March, when furnaces run. It’s also common year-round in the dry Southwest.
What Actually Helps Raise Humidity?
A small room humidifier set near the plant is the most effective fix. Misting raises humidity for only a few minutes, and wet leaves in a dim room invite fungal spots.
Other things that help:
- Group several houseplants together so they share moisture.
- Set the pot on a pebble tray with water below the pot’s bottom.
- Keep the plant out of bathrooms with no window, since humidity there doesn’t make up for the darkness.
Never keep the soil wet to make up for dry air. That trades crispy tips for root rot.
Fertilizer Burn and Salt Buildup
Too much fertilizer burns roots and leaf edges. Extra salts in the soil pull water out of the roots, so the plant wilts even when the soil is moist.
What Do Burned Leaf Tips and Soil Crust Mean?
Fertilizer burn shows as brown, crispy tips that spread inward, often on newer leaves first. You may al
