Carrion Plants Care Best Potting Mix

These soft-stemmed plants thrive in a well-draining cactus mix, like most succulents. The genus Stapelia thrives in a cactus potting mix with some organic matter.

But remember not too acidic, and it needs to allow the water to run freely from the drainage holes. Remember, the plant comes from tropical regions and also needs no feeding.

So, you can invest in a commercial mix or prepare one yourself. Here is a DIY recipe:

  • Five parts regular soil
  • Two parts perlite or pumice that helps retain moisture longer
  • Coconut coir to keep the pH levels right not to make it too acidic

Ideal Lighting For Your Thickly-Skinned Plant

Succulents Stapelia plants, you might think, bask all day in full sun. But, while your starfish flower succulent loves direct sunlight, it grows best in indirect sunlight, allowing some partial sun.

Placing your succulent group plants in insufficient light, on the other hand, blocks chlorophyll production. Eventually, this leads to discolored foliage.

Watering Needs For Starfish Cactus

Yes, we know you want to get your Stapelia cactus as big as possible to show off its striking feature, the flower. But, stop right there and do not go and overwater your Stapelia flower.

Most Stapelia plants store water to survive when temperatures reach a high. Please keep the soil lightly moistened and leave it dry between watering.

The soil should dry out instead of having consistent moisture leading to root rot. Yet, compared to several species in the cacti, it still needs more water.

You can water your Stapelia cactus during summer once every two weeks when spring arrives, and water your indoor plant at intervals once per month.

During winter, space out your watering schedule further. Or you can leave it the whole season. Provide your cacti with water if you leave the ground completely dry and notice the stems shriveling.

Temperature & Humidity 

Your Stapelia cactus loves a warm area with humidity. So, growing your plant is pretty easy in a container. The reason is that when it stands outside you can bring it indoors in winter.

In cold months it helps to keep the temperature above 50°F (10°C) and keep them dry for the winter season unless it starts to wilt.

Also, do not place your plant near a heated-up AC; instead, using a heated growing bench or a cover can keep the fragile parts surviving.

Still, placing them grouped with your other plant collection can provide your Stapelia flower with the moisture it needs.

Potting and Pruning Stapelia Flower

Once you notice your starfish plant stems begin growing too wide and tall, it is time to transplant them. Again, the best time to do this is in the growing season of spring.

Invest in a potting medium a bit wider, allowing the stems to grow in any direction. Place a layer of pebbles at the bottom to help improve the drainage.

Now, about pruning, there is no need to prune your succulents except for removing dead stems. You can also remove the flowers to encourage new blossoming when the flowers die.

Propagation of Stapelia Flower

These succulents can propagate by planting seeds or using stem cuttings. Still, remember when sowing seeds, it can take a couple of days for them to sprout.

For stem cuttings, you can use a sterilized sharp knife to remove a part of the mature plant. As with repotting, the best time is early spring or summer when it grows.

Leave your cuttings outside for the night to help the wounds heal. Get a pot ready with a potting mix and check that it has ample drainage.

Moisten the ground, place your seed/cuttings in it, and put it without a covering in light conditions with temperatures ranging between 59 to 64 degrees Fahrenheit (15 to 18 degrees Celsius.)

  • Stems become flabby and shriveled resulting from underwatering. Luckily, this is an easy fix by placing the container in a tray of water to soak up as much as it can. Then, allow the excess moisture to drain and water once the soil is parched.
