Why Are My Snake Plant Leaves Curling? 6 Causes and Fixes

By the Leaf & Thrive editors April 22, 2026 2 min read

Curling leaves on a snake plant (Dracaena trifasciata) are a stress signal. The plant is telling you that one of its basic needs is out of range. The good news is that snake plants are slow to decline, so a curl caught early is almost always reversible.

Work through these causes in order. They are listed from most to least common.

1. Underwatering

This is the leading cause. Snake plants tolerate drought well, but past a point the leaves lose rigidity and curl inward to reduce surface area and water loss.

How to confirm: the soil is bone dry several inches down, and the leaves feel slightly soft or wrinkled.

Fix: water thoroughly until it drains from the bottom, then let the top two inches dry out before the next watering. Curled leaves should firm up within a week.

2. Overwatering and root rot

Less common, but more serious. Constantly wet soil suffocates the roots, they begin to rot, and a plant with damaged roots cannot move water to its leaves, so they curl despite the soil being wet.

How to confirm: soil stays wet for many days, the base of the leaves feels mushy, and there may be a sour smell.

Fix: remove the plant, cut away any brown mushy roots, and repot into fresh, fast-draining soil. Hold off watering for two weeks.

3. Thrips

Thrips are tiny insects that pierce the leaf and drain its contents, which causes curling along with silvery or pale streaks.

How to confirm: look closely for slender pale insects, often along the leaf seams, and for stippled silver patches.

Fix: wipe the leaves down, then treat with insecticidal soap or neem oil every seven days for three to four weeks to break the breeding cycle.

4. Temperature stress

Snake plants want 18 to 27 degrees Celsius. Cold drafts or proximity to a heater can both trigger curling.

Fix: move the plant away from air-conditioning vents, exterior doors, and heat sources.

5. Too little light

In deep shade the plant cannot photosynthesise enough, and weak new growth may emerge curled or distorted.

Fix: move it to bright indirect light. A spot a metre or two from a window is ideal.

6. Pot-bound roots

A snake plant that has not been repotted in years can fill its pot so completely that water runs straight through without being absorbed.

Fix: repot into a container one size larger in spring.

The bottom line

Check watering first, because it explains most curling cases. If the soil reads dry, the cause is almost certainly underwatering and a good soak will fix it. If the soil is wet and the leaf bases are soft, treat it as root rot and follow our guide to saving an overwatered plant. Only after ruling those out should you inspect for thrips and review light and temperature.
