Whale Fin Plant Light Needs
Bright indirect sunlight is ideal, they do well in medium light conditions too, but will grow more slowly.
How Often to Water
They are succulents, so under-water them rather than over-water. The soil should dry out completely between waterings. The best thing to do is to check the soil each week with a finger or a wooden skewer, but only water it if dry all the way down
Use a dedicated cactus and succulent fertilizer in the summer to encourage growth.
Whale Fin Plant Soil

When To Repot

Do not mist this plant. They are fine a lower humidity levels.
18-25°C (64-77°F) is ideal. They’ll be fine if the temperature drops off at night as long as it isn’t freezing.
Whale Fin Plant Propagation
You can propagate a whale fin plant by taking cuttings:
- Wait till the plant produces at least one or more smaller plant at it’s base.
- Cut one of the ‘fins’ off, making sure to leave at least one fin on the plant.
- Cut the fin in sections making sure each section is over an inch long (2.5cm). It is worth using a pencil to put an arrow on each cutting denoting which way is up, as they must be propagated the same way they were on the plant.
- Let the cuttings callous over for 3 or 4 days so the wounds heal. This will reduce rot a lot.
- Put the cuttings (the right way up) in a shallow cup of water to root. The bottom should be under the water and the top out.
- Leave them for a couple of months to root, topping up the water when needed.
- Then pot them up into their own pot in cactus soil.
