Why Are My Plant’s Leaves Curling?

Curling leaves are usually a sign that a plant is reacting to stress, but leaf curl does not point to one specific problem. Soil that is too dry or too wet, intense sunlight, dry air, temperature changes, pests, and root trouble can all cause leaves to curl.

Before changing your plant’s care, check the potting mix, examine the leaves closely, and think about anything that has recently changed in the plant’s environment. You can also visit our Plant Care resource center for care information on specific plants and common problems.

Is the Curling Normal?

Some plants naturally have curled, folded, crinkled, or wavy leaves. Shangri La Pothos, for example, produces leaves that remain curled rather than opening flat. Prayer Plant leaves may fold upward at night as part of their natural daily rhythm.

New leaves may also remain rolled or folded while they develop. Give a new leaf time to open before assuming something is wrong. If it becomes stuck, browned, torn, or badly distorted, inspect the plant more closely.

If the leaves are firm and correctly colored and the plant continues producing healthy growth, the shape may be normal for that plant.

The Potting Mix Is Too Dry

When a plant cannot take up enough moisture, its leaves may curl or fold inward. The plant may also wilt, develop dry edges, or feel unusually light in its pot.

Signs the Plant May Be Too Dry

The potting mix feels dry below the surface
The grower’s pot feels unusually light
Leaves are curling inward or folding together
The plant is wilting or drooping
Leaf edges are brown and crispy
The potting mix has pulled away from the sides of the pot

Check the potting mix below the surface rather than judging it only by appearance. If the mix is dry enough for that type of plant, water thoroughly until excess water begins to drain from the bottom of the grower’s pot. Empty any water that collects in the decorative pot or saucer.

Avoid giving the plant small amounts of water repeatedly. Moisten the root zone evenly, allow excess water to drain, and then wait until the plant needs water again.

Different plants have different moisture needs. If you are unsure where to begin, review How Do I Care for My New Plant? for information on checking potting-mix moisture, watering thoroughly, and avoiding standing water. A fern may need water when the surface of the potting mix begins to dry, while a cactus, ZZ Plant, or succulent should dry much more thoroughly.

The Potting Mix Is Staying Too Wet

A plant can develop curling leaves even when plenty of water is present. Potting mix that remains wet can damage the roots and prevent them from supplying the leaves with the moisture and oxygen they need. If the curling is accompanied by yellowing, use Why Plant Leaves Turn Yellow—What It Means and What to Do to help narrow down the cause.

Signs the Potting Mix May Be Too Wet

The potting mix remains wet for an unusually long time
Water is standing inside the decorative pot or saucer
Leaves are curling and turning yellow
Leaves or stems feel soft or limp
The plant is dropping leaves
The potting mix has an unpleasant smell
Roots are brown, soft, or damaged
The container is much larger than the plant’s root system

Empty any standing water and wait until the potting mix has dried to the level recommended for the plant before watering again. Make sure the plant is in a grower’s pot or another container with drainage holes.

Do not simply stop watering for a set number of days. Drying time varies depending on the plant, pot size, potting mix, root system, temperature, and amount of light it receives.

The Plant Is Receiving Too Much Sun or Heat

Intense sunlight and heat can cause a plant to lose moisture more quickly than its roots can replace it. Leaves may curl or fold to reduce the amount of surface exposed to the light and heat.

Signs of Sun or Heat Stress

Curling is worse on the side facing the window
Leaves have pale, tan, bleached, or scorched areas
Leaf edges are dry or crispy
Leaves feel unusually warm
The plant was recently moved into stronger light
Hot afternoon sunlight passes directly through the window

Move the plant away from intense afternoon sunlight or filter the light with a sheer curtain. Do not move it into a dark location; provide the amount of light recommended for that type of plant. Many houseplants can take direct sun until about 10 am but after that the light generally becomes too intense for houseplants and can cause leaf scorch/burning.

The Air Is Too Dry

Plants that prefer higher humidity may curl or develop dry edges when the surrounding air is exceptionally dry. Heating and air-conditioning vents can make the problem worse by continually moving dry air across the leaves.

Signs Dry Air May Be the Cause

Leaves are curling and developing brown, crispy edges
The plant is near a heating or air-conditioning vent---the vent is blowing on or around the plant
The potting mix has adequate moisture
Other humidity-loving plants nearby have similar damage
The problem began when indoor heating or air conditioning started running more often---keep in mind when seasons change heating and cooling systems turn on and change our environment. Never allow vents to push air onto the leaves of plants

Move the plant away from heating and cooling vents. If it needs higher humidity, consider grouping it with other plants or using a humidifier nearby.

Do not compensate for dry air by keeping the potting mix constantly wet. Extra water around the roots does not correct low humidity and may cause root problems.

Misting is not an effective way to provide lasting humidity. If the plant needs higher humidity, grouping plants together, using a pebble tray, or running a humidifier will be more effective. Water droplets settle on the leaves without significantly increasing the moisture in the surrounding air and can cause bacterial and fungal issues in the leaves.

Pests Are Damaging the Leaves

Pests that feed on tender foliage can cause new leaves to curl, twist, wrinkle, or emerge distorted. Spider mites, thrips, aphids, and other pests may be especially noticeable around new growth. Fine webbing and pale, stippled leaves are common signs of spider mites. See How to Get Rid of Spider Mites for identification and treatment guidance.

Signs of a Pest Problem

New leaves are twisted, puckered, or unusually small
Tiny insects are visible on new growth or leaf undersides
Fine webbing appears between leaves or stems
Leaves have pale speckles or silvery scars
Leaves or stems feel sticky
Small dark specks appear around damaged areas
Similar damage is spreading to nearby plants

Separate the affected plant from other plants and inspect the leaf undersides, stems, and new growth closely. A magnifying glass may help you spot very small pests.

Identify the pest before choosing a treatment. If using insecticidal soap, horticultural oil, or another pest-control product, follow all label directions.

The Roots Are Stressed

Leaf curling may begin after repotting, shipping, severe drying, prolonged wetness, or physical damage to the roots. If the plant was recently purchased, review When Should You Repot a New Houseplant? before disturbing the roots again. A plant with a small or damaged root system may struggle to take up moisture even when the potting mix is damp.

Signs of Root Stress

Curling began after the plant was repotted
The plant feels loose or unstable in the pot
The plant has very few healthy roots
The container is much larger than the root system
Potting mix remains wet around a small root ball
The plant was recently shipped
Correcting light and watering has not improved the plant

Keep the plant’s environment stable while its root system recovers. Avoid repeatedly repotting or disturbing the roots unless there is a clear problem with drainage, pot size, or root health. When repotting is necessary, follow How to Repot a Houseplant.

Wait until the plant begins actively growing again before fertilizing. Fertilizer will not repair damaged roots and may place additional stress on the plant.

The Plant Experienced a Temperature Change

Cold drafts, excessive heat, or abrupt temperature changes can cause leaves to curl, brown, or drop. Temperature damage may not become visible immediately after the plant is exposed. Plants can also react to abrupt changes in light, temperature, humidity, or location. Help Your Plants Adapt Faster to Your Home Environment explains how to reduce stress while a plant adjusts.

Signs of Temperature Stress

The plant was recently shipped during hot or cold weather
Leaves touched a cold window
The plant is near an exterior door
The plant is close to a fireplace, heater, or air conditioner
Leaves have dark, brown, or water-soaked areas
Several leaves began declining at the same time

Move the plant to a stable location with temperatures appropriate for that species. Keep it away from drafts and extreme heat, but do not attempt to correct temperature damage by giving it extra water or fertilizer.

The Plant Received Too Much Fertilizer

Excess fertilizer can damage roots and cause brown edges, curling, or distorted new growth.

Signs of Excess Fertilizer

Symptoms began shortly after fertilizing
A white or crusty buildup is visible on the potting mix or pot
Leaf edges appear brown or burned
New growth is curled or distorted
More fertilizer than recommended was applied

Stop fertilizing until the plant begins recovering. Check that the fertilizer was measured and applied according to the product label.

If excess fertilizer is suspected and the container drains freely, run room-temperature water thoroughly through the potting mix and allow it to drain completely. Empty any water from the decorative pot or saucer.

Do not add fertilizer simply because leaves are curling. Curling alone is not enough to diagnose a nutrient deficiency.

How to Narrow Down the Cause

Start with these five questions:

Is the curled or folded shape normal for this plant?
Is the potting mix too dry or staying too wet?
Are older leaves, new leaves, or only one side of the plant affected?
Are pests, scars, webbing, or other damage visible?
What recently changed, such as watering, location, temperature, repotting, shipping, or fertilizing?

Use the other symptoms to help narrow down the cause:

Dry potting mix with inward curling or wilting: The plant may need water.
Wet potting mix with yellowing or soft growth: Check for excess moisture or root trouble.
Curling on the window-facing side: Check for excessive sunlight or heat.
Crispy edges near a vent: Check humidity and airflow.
Twisted or scarred new growth: Inspect for pests.
Curling after repotting: Keep conditions stable while the roots recover.
Curling after shipping or cold exposure: Consider temperature damage.
Firm, healthy leaves that are consistently curled: The shape may be normal for the plant.

Leaf direction alone cannot provide a definite diagnosis. Always consider the potting mix, accompanying symptoms, and the plant’s recent care.

Will Curled Leaves Flatten Again?

Some leaves may relax after the problem is corrected, especially when the plant was temporarily too dry. Leaves damaged by pests, heat, cold, or root trouble may retain their curled or distorted shape.

Watch the plant’s new growth for signs of recovery. Healthy new leaves are usually a better indication of improvement than whether every older leaf becomes perfect again.

When Should I Be Concerned?

Inspect the plant promptly if:

Curling is spreading rapidly
New leaves repeatedly emerge distorted
Stems or the center of the plant feel soft
The potting mix smells unpleasant
Roots are brown, soft, or falling apart
You see insects, webbing, scars, or sticky residue
Leaves develop black or water-soaked areas
The plant continues declining after its basic care has been corrected

Frequently Asked Questions

Should I Water My Plant as Soon as Its Leaves Curl?

Not automatically. Check the potting mix first. Both dry soil and root problems caused by wet soil can result in curled leaves.

Does Leaf Curling Always Mean Low Humidity?

No. Dry air is one possible cause, but watering problems, excessive heat, pests, root damage, and temperature stress can cause similar symptoms.

Should I Mist Curled Leaves?

No. Misting does not correct watering or root problems and does not provide a lasting increase in humidity. If the plant requires higher humidity, use a humidifier or move it away from dry airflow.

Should I Fertilize a Plant With Curling Leaves?

Wait until you know why the leaves are curling. Fertilizing a plant with damaged roots or excess fertilizer already present in the potting mix can make the problem worse.

Should I Remove Curled Leaves?

Leaves that are still mostly healthy can continue providing energy to the plant. Remove leaves that are fully dead, badly damaged, or heavily infested, but avoid removing large amounts of useful foliage from an already stressed plant.

Can Curled Leaves Be Normal?

Yes. Some plants naturally produce curled, folded, crinkled, or wavy leaves. Others fold their leaves at certain times of day. Check the normal growth habit of your plant before changing its care.
