Why Is My Snake Plant Skinny and What To Do About It

A skinny snake plant can result from two situations. Some varieties are naturally thin and cylindrical, while in other instances, a standard variety grows weak and spindly, signaling a health issue. Understanding whether your plant is exhibiting its natural growth pattern or requires a care adjustment is the first step.

Naturally Skinny Snake Plant Varieties

Some snake plant varieties are known for their slender leaves and are not unhealthy; this appearance is a natural characteristic. One popular example is Dracaena angolensis, formerly known as Sansevieria cylindrica and commonly called the African Spear Plant. Its leaves are tube-like, growing straight up or arching outwards from a central rosette, and can be braided or left to grow naturally.

Another naturally slender variety is Dracaena bacularis. This plant features thin, upright, cylindrical leaves that are smooth and have a deep green color. It is often confused with Dracaena angolensis but tends to have a more compact growth habit. The leaves grow in a dense cluster, creating a minimalist and modern aesthetic.

The ‘Fernwood’ hybrid is another snake plant with a naturally slender profile. A cross between Dracaena suffruticosa and Dracaena parva, ‘Fernwood’ has arching, V-shaped leaves that are thinner than those of the common snake plant. The leaves grow in a fountain-like shape from the base, giving the plant a full but delicate appearance.

Reasons for Unhealthy Skinny Growth

When a broad-leafed snake plant develops thin, weak, or stretched-out leaves, it is a sign of an underlying issue. The most common cause is etiolation, which occurs when the plant does not receive enough light. In low-light conditions, the plant will stretch towards the nearest light source, resulting in elongated, pale, and spindly growth.

Improper watering can also lead to skinny growth. Overwatering is a frequent problem for snake plants, which are susceptible to root rot. When the roots sit in waterlogged soil, they begin to decay and lose their ability to absorb water and nutrients. This lack of nutrient uptake weakens the plant, causing the leaves to become thin and unable to support themselves.

A nutrient-poor soil mix can contribute to weak and skinny leaves. Snake plants are not heavy feeders, but they do require some nutrients to thrive. If the plant has been in the same pot for several years, the soil may be depleted of essential minerals. Without these nutrients, the plant cannot build strong, thick leaves.

Care for Strong and Healthy Growth

Providing the right amount of light is important for preventing weak, skinny growth. Snake plants thrive in bright, indirect light. Placing your plant near a window where it receives several hours of filtered sunlight will give it the energy needed for robust growth.

Proper watering techniques are important for maintaining a healthy snake plant. These plants are succulents and store water in their leaves, making them drought-tolerant. It is best to allow the soil to dry out completely between waterings. This practice prevents the soil from becoming waterlogged and protects the roots from rot, ensuring they can deliver water and nutrients to the leaves.

Snake plants require a well-draining soil to prevent water from accumulating around their roots. A cactus or succulent mix is ideal, or you can create your own by amending standard potting soil with perlite or sand to improve drainage. Repotting the plant every three to five years can also replenish nutrients and give it more space to grow.
