Gasteria might be a slow grower, but it’s a highly rewarding plant to propagate. Whether you’re expanding your collection, rescuing a struggling plant, or sharing with friends, Gasteria offers a few simple propagation methods that work for all varieties.
These hardy South African succulents can be propagated by leaf cuttings, offset division, and occasionally by seed. Each method has its own timing and quirks, but all are beginner-friendly when done right.
Let’s walk through how to multiply your Gasteria successfully—indoors or out.

When to Propagate Gasteria
The best time to propagate is during the plant’s active growing season—typically spring through early fall.
You’ll get faster root development and a better chance of success.
Avoid propagation in winter when the plant slows down and prefers to rest.
Method 1: Propagating Gasteria from Offsets
Most Gasteria plants produce pups or offsets around the base of the mother plant.
These are the easiest and most reliable way to create new plants.
-
Gently remove the mother plant from its pot and shake away excess soil.
-
Locate the offsets—they’ll be attached to the base with their own small root systems.
-
Use your fingers or a clean, sharp knife to separate them. If there’s no root system, they can still be propagated like a leaf cutting.
-
Let any open cuts callous over for 1–2 days in a dry, shaded spot.
-
Pot each offset in dry succulent mix, and water lightly after 4–5 days.
Place the new plants in bright, indirect light, and water only when the soil has fully dried out.
Method 2: Leaf Cuttings (Slower, but Effective)
Gasteria can also be propagated from individual leaves, though the process takes more time than offsets.
-
Choose a healthy, mature leaf and cut it cleanly at the base using sterilized scissors or a knife.
-
Allow the leaf to callous over in a dry, shaded area for 5–7 days.
-
Insert the calloused end into a well-draining succulent mix, burying about 1 inch deep.
-
Mist the soil lightly every few days, or water sparingly after 1 week.
-
Be patient—roots and pups usually develop in 4–6 weeks, and full plants may take a few months to establish.
Keep the cutting in bright, indirect light during rooting. Avoid direct sun, which can dehydrate the leaf before rooting begins.
Method 3: Propagation from Seed (Slow and Rare)
Gasteria can be grown from seed, but it’s rarely necessary unless you’re trying to hybridize or grow a large batch.
-
Sow fresh seeds on top of lightly moistened cactus or succulent mix.
-
Press gently into the surface but don’t bury them.
-
Cover with a humidity dome or clear plastic wrap and place in bright, indirect light.
-
Keep the soil evenly moist (but never soggy) until germination, which can take 2–4 weeks or longer.
-
Once seedlings are large enough to handle, transplant into individual pots.
Seed propagation is best for enthusiasts or those looking to experiment with rare hybrids.
Can Gasteria Be Propagated in Water?
Yes—Gasteria can root in water, but it’s not the preferred method.
Its thick, fleshy leaves and stems are prone to rot if left submerged too long.
If you choose to try water propagation (especially with offsets or thick leaf cuttings), follow these tips:
-
Use a shallow container and only submerge the bottom inch of the cutting.
-
Change the water every 2–3 days to prevent bacterial buildup.
-
Keep the container in bright, indirect light—never in direct sun.
Bonus Tip: Add 1–2 drops of a succulent-safe fertilizer (such as 2-7-7 like this one or 5-10-10 like this one) to the water to encourage faster root development. Just be careful not to overfeed.
Once roots reach about an inch long, move the cutting into dry soil and water after a few days.
Once your new plant begins to mature be sure to give it the correct care as outlined in the article Gasteria Care: Growing These Spotted Succulents Indoors and Out.
Propagating Gasteria Outdoors
In warm climates (zones 9–11), you can propagate Gasteria directly in the garden:
-
Take offsets or leaf cuttings and let them callous for a few days.
-
Plant directly in well-draining soil in a shaded or dappled sun location—never full sun.
-
Avoid watering for the first 4–5 days, then begin light watering as needed.
Outdoor propagation is ideal for rock gardens, shaded patios, or protected succulent beds where you want Gasteria to spread naturally.
If temperatures drop below 40°F (4°C), bring your new plants indoors to overwinter.
Final Thoughts
Whether you’re dividing offsets, rooting leaf cuttings, or dabbling with seed, Gasteria propagation is a straightforward and rewarding way to grow your collection.
These spotted, slow-growing succulents may take time, but once established, they’re hardy, long-lasting, and full of personality.
Keep your new cuttings out of harsh sun, water with restraint, and enjoy watching your baby Gasterias grow strong—one tiny tongue-shaped leaf at a time.
