Sansevieria trifasciata, and other varieties more popularly known as the snake plant, mother-in-law’s tongue, and Viper’s bowstring hemp, are low-maintenance, highly-tolerant succulents regarded as one of the most favorite houseplants.
This member of the Asparagaceae family is native to West Africa tropics and grows readily in the USDA hardiness zones 9b to 11.
This decorative plant is often the first choice of the majority of the home-owners for their living rooms as it purifies the air and beautifies a modern house or apartment with its dark green, sword-like foliage.
The thick, upright leaves hold the moisture and allow Sanseviera to outshine other houseplants even during droughts and low light conditions.
While it’s particularly hard to damage this versatile plant, some conditions cause its beautiful green and yellow strappy leaves to curl, droop, or fall over.
Why Are Snake Plant Leaves Falling Over?
A striking feature of snake plants is its pointy, erect leaves which grow from 8” inches to 5’ feet tall.
Home gardeners often complain about their snake plant leaves falling over or bending randomly.
This condition is caused by overwatering, lighting issues, or incorrect repotting practices.
Like all types of succulent plants, the mother in law plant stores water in its leaves.
This makes it flourish in its native dry, rocky environment.
Sansevieria dislikes wet feet and suffers from root rot if overwatered or the soil is poorly-drained.
Another reason is placing the Sansevieria in areas without any light for prolonged time periods.
Although snake plants are extremely hardy and grow well without being exposed to direct sunlight, extended absence from bright light or exposure to intense direct light cause leaves to fall over.
If there are no watering or lighting issues with the snake plant, the reason for the droopy leaves might be the rootbound caused by improper repotting.
Repotting more frequently than 3 to 5 years or placing it in a pot too large for it also leads to rotting roots.
What Damage Does It Cause?
Sansevieria plant leaves falling over is an indication of an underlying problem with the plant.
The roots of snake plants, when over-watered, become soggy and thirsty for the much-needed oxygen and nutrients from the soil.
Rotten roots affect the overall health of the plant, spreading to the healthier roots as well.
Fungus in the poorly-drained soil develops due to over-watering and kills the roots.
The roots of snake plants are normally firm and black or pale in color, whereas rotten roots are soggy, mushy, and blackish-brown in color.
While the roots remain buried, the leaves falling over is a tell-tale sign of rot.
Sansevieria also undergoes a damaging root condition called root bound.
As the name suggests, the problem arises when the roots of snake plants are restricted or “bound” by a barrier. Sansevieria plants are very forgiving of being pot or root-bound
When the container of the plant is too small for it and starts to inhibit healthy new growth.
If grown outdoors, walls, footer, or piping can act as a barrier.
Consequently, the leaves will fall over to indicate stunted growth.
How To Prevent Snake Plant Leaves From Falling Over?
Keep the soil moist but not wet. Using extra caution in watering the plant would go a long way.
Water Sansevieria when 2“ – 3” inches of the soil is dry to touch.
Snake plants exposed to the partial sun would need more frequent watering.
Water the plant once every 2-3 weeks and stop watering once the water runs through the drainage hole of the container.
Water the plant once a month during winter months. Again make sure the pot has drainage holes.
Sansevieria care includes a fast-draining potting mix or a regular potting soil combined with coarse sand or perlite added to a pot one size larger.
Expose the indoor plant to the southern window during winter and an east-facing window is suitable for the rest of the year.
If the plant has developed rotten roots, wash and trim the rotten roots and place in a new pot with good drainage.
Prune the drooping leaves.
Avoid adding any fertilizer to the pot until the roots have restored their health.
