Snake plants (Sansevieria spp.), also known as mother-in-law’s tongue, are some of the easiest and most resilient houseplants to grow.

Not only do they thrive on neglect, but they’re also celebrated for their air-purifying abilities and architectural beauty.

One of the most exciting parts of growing snake plants is when they begin to produce “pups”—new baby plants that grow from the base of the mother plant.

These pups can be separated and propagated, allowing you to expand your collection or share plants with friends.

But what if your snake plant never produces pups, even after years of growth? While it may seem like a mystery, the truth is that several environmental and care-related factors can prevent your snake plant from multiplying.

In this guide, we’ll explore 7 common reasons why your snake plant isn’t producing pups, and offer proven solutions to help you encourage healthy, robust growth.

1. The Pot Is Too Large or Too Small

Why it matters:

Snake plants prefer slightly tight conditions to trigger pup production. If the pot is too large, the plant will spend more energy establishing roots instead of growing new shoots.

Conversely, if the pot is too small, it may become root-bound and stressed, which also inhibits pup formation.

Solution:

Choose a pot that is just 1-2 inches larger than the current root ball. This provides enough room for gradual growth without overwhelming the plant. Avoid frequent repotting unless necessary.

2. Insufficient Light

Why it matters:

Although snake plants are often labeled as “low-light plants,” they thrive in bright, indirect light. While they can survive in dim corners, low light significantly reduces their growth rate and delays or completely halts pup production.

Solution:

Move your snake plant to a brighter location, such as a north- or east-facing window. If natural light is limited, consider using a grow light to supplement. Avoid direct sun, especially in the afternoon, as it can scorch the leaves.

3. Lack of Nutrients

Why it matters:

Snake plants are slow growers and don’t need frequent feeding, but a complete lack of nutrients can stall pup development.

If your plant hasn’t been fertilized in over a year, it’s likely lacking key minerals such as nitrogen, phosphorus, and potassium.

Solution:

Feed your snake plant with a balanced, diluted houseplant fertilizer (10-10-10 or 20-20-20) every 6–8 weeks during the active growing season (spring and summer). Avoid fertilizing in winter when the plant is dormant.

4. Overwatering or Poor Drainage

Why it matters:

Overwatering is one of the most common mistakes with snake plants. Wet soil can lead to root rot, weakening the plant and preventing it from putting energy into pup production.

Solution:

Use a well-draining soil mix, preferably a cactus or succulent blend.
Water only when the top 1–2 inches of soil feel dry.
Ensure the pot has drainage holes to prevent soggy roots.
During winter, reduce watering frequency significantly.

5. Not Enough Time or Maturity

Why it matters:

Pup production is more likely to occur once a snake plant matures and becomes well-established. Younger or recently propagated plants may take 1–2 years or more to start producing pups, especially if other growth factors are not ideal.

Solution:

Patience is key. Allow the plant to grow undisturbed and focus on providing consistent care. Avoid repotting, pruning, or disturbing the roots frequently. Once the plant is mature and comfortable, it will reward you with pups.

6. Cold Temperatures or Drafts

Why it matters:

Snake plants are native to warmer, tropical climates. Exposure to cold drafts or temperatures below 50°F (10°C) can stress the plant and suppress growth and reproduction.

Solution:

Keep snake plants in rooms where temperatures stay between 60–85°F (15–29°C).
Avoid placing them near air conditioners, drafty windows, or outside during colder months.

7. Stress or Environmental Changes

Why it matters:

Sudden changes in environment—like moving the plant, changing lighting drastically, or repotting—can cause stress, which diverts the plant’s energy to recovery instead of reproduction.

Solution:

Minimize unnecessary movement or changes. If you must move or repot, do it gradually and during the spring, giving the plant time to adjust. After repotting, wait at least a year before expecting new pups.

Bonus Tip: Some Varieties Are Slower to Pup

While most Sansevieria varieties eventually produce offsets, some—like Sansevieria cylindrica or Sansevieria moonshine—tend to be slower to propagate through pups than common varieties like Sansevieria trifasciata (now Dracaena trifasciata).

Don’t worry if your plant is healthy and growing but slow to multiply—every plant has its own pace.

How to Spot a Pup When It Does Arrive

Snake plant pups usually emerge from the soil near the base of the mother plant. They look like miniature versions of the adult plant, often lighter in color and tightly coiled at first.

These offsets grow from rhizomes, horizontal stems that run just beneath the soil.

You can choose to leave them in the pot to grow into a fuller plant, or separate them for propagation once they’re a few inches tall and have their own roots.

While snake plants are easy to care for, encouraging them to produce pups requires the right balance of light, water, nutrients, space, and time.

Often, it’s not a question of if your snake plant will produce pups—but when. By optimizing growing conditions and eliminating sources of stress, you create an environment where your snake plant can flourish and multiply.

Once your snake plant begins producing pups, you’ll have plenty of new plants to propagate, gift, or grow into a lush indoor jungle.

With a little patience and the right care, your snake plant will reward you with healthy growth and a growing family of green companions.
