Origins and History
Kalanchoe pinnata is native to the coast of Madagascar. In its native habitat, it grows along rocky and sandy shores.
Over time, the plant made its way to other tropical areas. It is currently naturalized in areas including Australia, India, Brazil, and Hawaii.

How to Grow Kalanchoe Pinnata (Cathedral Bells) at Home
Cathedral bells can grow up to five feet tall. It is slow-growing, so it will take multiple years for it to grow this tall.
What to Do Before Planting Kalanchoe Pinnata
Before you add a Kalanchoe pinnata plant to your home, you’ll need to make sure you have the right environment for it.
Since these plants thrive when they receive lots of light, look for a bright location in your home. Once you’ve found a spot, make sure it can handle this plant’s growth. Remember it can grow up to five feet tall!
What’s the Best Soil Mix for Kalanchoe Pinnata Plants?
Well-draining soil is essential. A potting mix labeled for cacti or succulents is a great choice.
You’ll want to avoid potting mixes labeled for houseplants. These mixes hold more water than Kalanchoe pinnata prefers.
If you’d like to make your own potting mix, combine the following:
- two parts sand
- two parts peat moss
- one part perlite
How to Plant
When you plant cathedral bells, you want to make sure you provide excellent drainage. This involves using a well-draining potting mix and selecting a container with drainage holes.
Kalanchoe Pinnata Light Preferences
Cathedral bells need at least six hours of daily light. If they receive less light, they will appear stunted and weak.
They prefer direct sunlight, but they will also perform well in indirect light. The most important aspect is to make sure they receive enough hours of light.
One location that works well for this plant is near a south-facing window. A spot in a bright room or west-facing window will also work well.
Temperature & Humidity Preferences
Kalanchoe pinnata prefer temperatures that are between 65-85ºF. It is extremely sensitive to cold and will suffer if temperatures dip below 50ºF for an extended period of time.
Since this plant doesn’t like the cold, make sure to keep away from cool drafts. Avoid placing it near poorly insulated windows, exterior doors, and air conditioning vents.
As far as humidity, cathedral bells aren’t too picky. These plants prefer low to moderate humidity, but they can grow well in high humidity as well.

When and How to Water Kalanchoe Pinnata Plants
Since Kalanchoe pinnata plants can store water in their fleshy leaves, they can withstand periods of drought. With this in mind, be aware that overwatering is more common than underwatering.
During the spring and summer, Kalanchoe pinnata will only need to be watered every two to four weeks. When the shorter days of fall and winter arrive, you will only need to water once every one to two months.
You should water these plants when the top two inches of the potting mix is dry.
When you water, you want to aim for a soak and drain method. This involves thoroughly wetting the soil until water runs out the bottom of the container and then waiting until the soil is dry. By watering in this manner, you mimic the intense storms the plant experiences in its natural environment.
Do Kalanchoe Pinnata Need Fertilizing?
Cathedral bells plants don’t require much fertilizer. Applying fertilizer that is too strong or fertilizing too often can lead to salt buildups. In turn, your plants will suffer.
Fertilizing once in the late spring or early summer is sufficient. Choose a balanced fertilizer designed for succulents and dilute it to half the recommended strength.
Cathedral bells don’t require much pruning, but you can trim them to keep them looking tidy.
If your plant is growing too tall or too wide, use a pair of sanitized pruning shears to trim the tips of stems. Avoid removing more than one-third of the plant’s foliage at one time.
If you’re lucky enough to witness your plant flower, you’ll find the flowers will eventually die. When this happens, clip the flower stalk near the base of the plant.
How to Propagate Kalanchoe Pinnata Plants
Kalanchoe pinnata is easy to propagate via the following methods.
Leaf or Stem Cutting
You can easily propagate a new plant via a leaf or stem cutting.
To take a stem cutting, use a sharp pair of shears to remove a piece of stem that is four to six inches long. Simply cut off a leaf to obtain a leaf cutting.
Once you have your leaf or stem cutting, follow these steps.
- Set your cutting in a cool, dark place until the wound heals over. This should only take a few days.
- Once the wound is healed, dip the cut end in a rooting hormone. While this is optional, it will speed up the rooting process.
- Place the cutting in a container of well-draining potting mix. You only need to bury 1/4 inch of the cutting.
- Water well.
- Cover the container with a plastic bag or plastic container. This will help increase humidity.
- Wait two to four weeks for roots to form.
- Remove the plastic and treat the cutting as you would treat an established plant.
Kalanchoe pinnata plants sometimes produce plantlets along their leaf margins.
By removing these plantlets and placing them in potting soil, you can produce new plants.
Repotting Kalanchoe Pinnata
Cathedral bells will benefit from repotting every two to three years. When it’s time to repot, follow these steps.
- Obtain a container that is slightly larger than the old container. Make sure the new pot has drainage holes.
- Remove your plant from its container. Dust off any excess soil and inspect roots for any signs of rot. Trim any unhealthy roots.
- Add a couple of inches of fresh potting soil to the new container.
- Place the plant into the new pot.
- Fill the pot with fresh potting soil.
- Water well.
Common Kalanchoe Pinnata Problems & How to Treat Them
While Kalanchoe pinnata foliage is gorgeous, most growers would like them to flower. However, encouraging these plants to flower isn’t as easy as you may hope.
The most common causes of a lack of flowering are not enough light or too cold of a temperature.
Root rot is a type of fungus that affects plant roots. When roots become soft, they are unable to take up water and nutrients.
When a plant can’t obtain the water and nutrients it needs, it may turn yellow or look stunted.
Overwatering is the number one cause of root rot. Remember that Kalanchoe pinnata plants only need to be watered every few weeks.
If you suspect your plant has root rot, remove it from the pot to inspect the roots. Clip off any infected portions and repot the plant in fresh potting soil. From this point on, decrease the amount you water.
Aphids are small insects with sucking mouthparts. They drink plant sap and may spread disease while feeding.
Aphids rapidly multiply, so it’s important to begin treatment as soon as you notice the pests.
You can wipe off small numbers of aphids using a soapy cloth. If you have a large infestation, you may spray your plant with insecticidal soap or neem oil.
You won’t need any special tools to care for Kalanchoe pinnata. Just make sure to use a container with drainage holes and a well-drained potting mix.
Cathedral bells are a great addition to any indoor space. As long as you provide enough light, keep the air warm, and water with restraint, you’ll have a healthy plant for years to come.
