Kalanchoe Care As A Houseplant & In The Garden

Oh, how I love succulents! And a succulent with lots of long-lasting flowers is just the cat’s meow. Enter the popular Kalanchoe blossfeldianas that are most commonly sold as indoor plants. In Santa Barbara, where I used to live (USDA zone 10), mine enjoyed the great outdoors year-round. This is about Kalanchoe Care indoors and outdoors, or Kals as we call them.

These long, lasting blooming plants with colorful flowers will brighten up both your garden and home. If you want the flowering period to be more long-lasting, buy your plant with at least half the flower buds partially or not yet opened. They’ll gradually open after you get them home. 

I buy mine at the farmers market, and although we used them a lot in the interiorscaping trade in offices and homes, I had never grown them in the garden before. I’ve discovered that Kalanchoes bloom almost all year round here with very little care. My kind of plant!

Botanical Name:  Kalanchoe blossfeldiana                

Common Names: Kalanchoe, Flowering Kalanchoe, Florist Kalanchoe, Flaming Katy

NOTE: This post was published on 07/16/2014. I’m updating it on 06/22/2023. It’s one of the very first posts that I ever wrote. My how blogging has changed!

I’ve since written newer posts on Kalanchoe Care as houseplants. Rather than extensively update this post, I will list these more current posts Kalanchoe Care, Calandiva Care, and Growing Kalanchoe FAQs with more information and tips.

Kalanchoe Care In The Garden

This is a Calandiva, a popular cultivar of the Flowering Kalanchoe. It has rosebud flowers & the same care requirements. So many blooms!

Light Requirements

Bright shade. Mine get bright light and one or two hours of direct sun in the summer, no more. Too much direct sunlight will cause burn.

Water Requirements

Once a week, thoroughly. They’re succulents, so they like to dry out between waterings.

Soil

Mine are planted in pots in half organic potting soil and half Succulent and Cactus Mix. Kalanchoes are succulents susceptible to root rot; they must be planted in well-draining soil.

Fertilizer

I don’t use any. I plant with worm castings, then top dress with worm castings and compost every spring. Once or twice during the warm months, I’ll water in some seaweed extract.

Pests

None so far, but then they can be susceptible to mealybugs and aphids.

Pruning Tip

I trim off the spent flowers, taking the stem down to where it meets the foliage. I don’t have to do it too often because the flowers are long-lasting, and the plant looks better this way.

Now, onward to caring for them as houseplants.  At the end of this post, I touch briefly on how to get them to bloom again indoors. Hint: it’s not easy.

Light Requirements

Give yours lots of bright indirect light. As bright as possible, something close to but not in a south and/or west-facing window.  Keep it away from the hot windows – touching that glass will burn it. Ouch!

Water Requirements

Every two weeks in the warmer months. Wait until the soil drys out before watering again. And don’t let it sit in water. Remember, they’re succulent plants that store water in their fleshy leaves and stems, so keeping them too wet can cause mildew.  

Too much moisture will also lead to root rot. They like to be kept on the dry side.

Tip: Yes, that paper or foil wrapping may be prettier than the grow pot but remove it when you water your plant. Remember, the Kalanchoe is a succulent, and too much water building up in the bottom will drown it out.

Soil

Use a potting soil mix formulated for houseplants with good drainage. A mixture of half potting soil and half Succulent and Cactus Mix would be fine. That’s what I used to plant up my new pink Kalanchoes.

Tip: Make sure the pot has drainage holes so the excess water can freely flow out.

Temperature

I say if your home is comfortable to you, then your houseplants should be just fine too. They would enjoy a vacation outdoors in the warmer months (refer to outdoor care above).

Fertilizer

Use an organic balanced liquid fertilizer like Sea Grow if you feel yours needs it.  Easy does it—only two yearly applications – once in mid-spring and the other in mid-summer.

Pests

Keep an eye out for Mealybugs. They leave behind a residue that looks like specks of cotton. Aphids and Scale can also be an issue.

Pruning Tip

The foliage grows very densely.  I snip away some of those leaves growing over the blooms. Those purdy little flowers will show more!

Getting Kalanchoes To Rebloom

Now, on to how to get them to bloom again. If yours hasn’t ever repeat bloomed, don’t feel bad.  I’ll start by saying “good luck” because you must work for it. 

Kalanchoes, like Poinsettias, are photoperiodic. This means they react to periods of light exposure and need at least 12-14 hours of darkness to bloom again.

Chances are, if you have them in your home, you have them in a room that isn’t getting that amount of complete darkness. Starting in winter, you must put them in a closet or a pitch-black room for 12-14 hours. And yes, they need that every night for two months. Be sure to cut back on the watering too.

Kalanchoe Blossfeldiana Flower Colors

Kalanchoes are known for their beautiful flowers, which come in vibrant red, orange, and pink shades. You can also find them in white and more subtle shades of pink. There are bi-color flowers as well.

The flowers are long-lasting, and the rich green leaves are attractive and shiny. A great blooming plant for the garden or your home!

In conclusion, taking care of a Kalanchoe plant is not as daunting as it may seem. With the right light levels, water, and well-drained soil, your kalanchoe can thrive and bring life to any room in your house or the right spot in your garden.

  1. So do I leave my kal in the closet all winter? But only take it out for the 8 hours of indirect sunlight right? I do this every day? And when I put them in the closet they seem to sprout new green stems of life, while there is leaves drying up and wilting. is this good or bad?

  2. Hi Caty – It can be a challenge. You want it to have more time in darkness (13-14 hrs.) & a little less time (11-10 hrs.) in bright natural light. You want to keep it on the drier side until (hopefully!) buds appear. Nell

  3. Hi I just bought baby succulent Kalanchoe farinacea and wanted some basic tips to help my little guy grow. I could tell in the store the a/c was making him sad. I did rotate him in the sun for 2 hrs and bought him inside.

  4. That’s good. I’ve done many posts on succulents you’ll find helpful. Next spring, I’ll be doing a series on growing succulents indoors. Nell
