Kalanchoe Care

Maintaining kalanchoe is a straightforward task when armed with essential guidelines and optimal conditions. Key requirements for successful kalanchoe cultivation include:

Planting in a loose, loamy, sandy, and well-drained potting medium, such as cactus mix or soil designed for succulents.
Positioning the plant in a warm indoor setting with bright, indirect light. When placing it outdoors, ensure it receives full sun but with protection from the late afternoon sun.
Allowing kalanchoe plants to completely dry out between watering sessions.
Fertilizing indoor kalanchoes once a month, specifically during the spring and summer seasons.

For optimal growth indoors, kalanchoe plants thrive in bright, indirect light. When cultivating them outdoors, partial shade to full sun is recommended. If planted in full sun, it’s advisable to provide some afternoon shade to prevent scorching. Leggy stems are an indicator of insufficient light exposure.

Outdoor kalanchoe plants flourish in well-drained, loamy, or sandy soil. Indoors, it’s recommended to use a potting mix that doesn’t retain excessive moisture, such as a 50% potting soil and 50% cactus mix, or a blend of 60% potting soil and 40% perlite. To ensure proper drainage and prevent excess moisture, planting kalanchoe in a clay pot can help wick away surplus water from the soil.

Kalanchoes are resilient to occasional forgetfulness in watering. These hardy plants require saturation only every few weeks, even less frequently in winter. Allowing the soil to completely dry between waterings helps prevent root rot. As succulents, kalanchoe leaves can store water, ensuring the plant’s well-being even if watering is delayed by a few days.

Temperature and Humidity:
Kalanchoe adapts well to household environments, thriving at temperatures between 55 to 80 degrees Fahrenheit. The plant is not overly sensitive to air moisture levels. For outdoor garden planting, it’s advisable to avoid zones below USDA hardiness zones 10 to 12, as kalanchoes are not frost-resistant and don’t thrive in temperatures below 55 degrees Fahrenheit.

While kalanchoes benefit from fertilizer like many flowering plants, they are less demanding. Garden-grown plants require light feeding in spring, while indoor plants should be fertilized with a well-balanced blend monthly during spring and summer, excluding winter. If flowering is sparse, a fertilizer higher in phosphorus can be used.

Growth Rate:
Kalanchoes typically have a slow growth rate, taking two to five years to reach maturity. ‘Flaming Katy,’ a common kalanchoe, reaches around 12 inches in height. Outdoor plants tend to grow faster due to brighter conditions. In colder climates, acclimating indoor kalanchoe plants to the outdoors when night temperatures are above 60 degrees Fahrenheit can provide extra sunlight. Bring them indoors as temperatures begin to drop in late summer or early fall.

Types of Kalanchoe

Kalanchoe blossfeldiana is offered in numerous unnamed varieties, showcasing a spectrum of colors including yellow, red, orange, pink, and white. When planted outdoors, these varieties typically bloom in spring, while indoor plants can be encouraged to flower almost year-round. Other related species also make excellent choices for both garden and indoor settings:

  • K. Mangini: Featuring fleshy leaves and large, bell-like pendant flowers, this species, also known as the chandelier plant, thrives in USDA hardiness zones 9 to 11. Prolonged flowering is facilitated by moist air conditions.
  • Kalanchoe daigremontiana: Commonly referred to as mother of thousands due to tiny plantlets along its leaf edges, this kalanchoe is hardy in USDA hardiness zones 9 to 11.
  • K. porphyrocalyx: Also called pearl bells, this species boasts slender, rectangular leaves and purple pendant flowers. It is hardy in USDA hardiness zones 11 and 12.

  • Kalanchoe tomentose: Recognized as a chocolate soldier or panda plant, this kalanchoe has thick, fuzzy leaves with a blue tinge and brown spots around their edges. It’s hardy in USDA hardiness zones 9 to 11.

Propagating Kalanchoe

Propagating Kalanchoe is a straightforward process that not only benefits the plant’s health but also helps manage the strain on the mature plant caused by offsets. Rather than allowing these offsets to draw nutrients from the mature plant, you can propagate them (or take stem cuttings) at almost any time. Here’s a step-by-step guide:

Cutting Preparation:
Use a sharp, clean knife or clippers to cut a segment of the stem, several inches long, from a mature plant.
If using an offset, remove it at the joint where it connects to the parent plant.

Drying Period:
Allow the cutting to dry out for a few days or until the end appears to have healed shut and calloused over.

Rooting Hormone Application:
Dip the calloused ends of the cutting in a rooting hormone to encourage the development of roots.

Plant the cutting in soil composed of the same mixture used to grow the mother plant.

Light Exposure:
Place the newly planted cutting in bright indirect light. Avoid watering it at this stage; the stem should take root within a month.

Post-Rooting Care:
Once the stem has taken root, you can start caring for it as you would a mature kalanchoe plant.

This simple propagation process allows you to cultivate new plants from mature ones, promoting the overall health of both the parent and propagated plants.

How to Grow Kalanchoe From Seed

These plants with a slow growth rate are commonly cultivated through cuttings for quicker outcomes. However, growing them from seeds is quite straightforward. In early spring, sow the seeds on the surface of a breathable potting mix. It’s crucial not to bury the seeds as they require light for germination. Enhance humidity by placing the container in a plastic bag until the seeds sprout, which typically takes around ten days. Following approximately two months, relocate the seedlings to separate pots or plant them directly outdoors.

Potting and Repotting Kalanchoe

In contrast to plants that thrive when pot-bound, kalanchoe plants flourish when repotted regularly. It’s recommended to repot your kalanchoe every fall after it has bloomed for optimal results. This practice stimulates new growth and enhances the plant’s overall fullness. When repotting, choose a container that is one size larger than the current one.

Ensure the use of a well-draining pot, with clay being a suitable material due to its porous nature, aiding in maintaining relatively dry soil conditions. This choice of container contributes to the health and well-being of your kalanchoe plant.

How to Get Kalanchoe to Bloom

Blooming Cycle:
The blooming cycle of Kalanchoe is initiated by extended periods of darkness, preferably lasting at least 14 hours, during the winter months. Approximately four months later, in spring, the plant rewards you with vibrant bursts of colorful flowers that can grace your space for several weeks. With careful light management, blooms can reappear throughout much of the year.

Sunlight Requirements:
To facilitate proper blooming, Kalanchoes need abundant sunlight during the day. However, intense direct sunlight can hinder the blooming process, so it’s best to provide bright, indirect light for optimal results.

Encouraging continual flowering involves the practice of deadheading spent flowers. Removing these spent blooms prompts the plant to produce more flowers. If you encounter difficulties in getting your Kalanchoe to bloom, consider using a fertilizer blend with a high phosphorus content, as this can stimulate the development of additional flower buds.

How to Keep Kalanchoe Blooming

Achieving continuous blooms from your kalanchoe indoors requires attentive care and a conducive environment. The key factor in this process is providing ample sunlight. Follow these steps to encourage your kalanchoe to bloom year-round:

Sunlight Requirement:
Ensure your kalanchoe receives a generous amount of sunlight. Place it in a location where it can bask in six to eight hours of bright light each day. This exposure is crucial for the plant to bloom optimally.

Fall and Winter Darkness:
During the fall and winter months, expose your kalanchoe to near-total darkness for the remaining hours of the day. To accumulate the energy needed for continuous blooms, the plant should experience a full 14 hours of darkness daily. This extended period of darkness should be maintained for at least six weeks.

By providing the right balance of light and darkness, you can create an environment that encourages your kalanchoe to bloom consistently throughout the year.

Common Problems With Kalanchoe

While kalanchoe plants are generally low-maintenance, challenges can arise when not properly tended to, particularly in terms of watering and exposure to temperature extremes.

Soft, Damaged Blooms, and Leaves:
Exposure to near-freezing temperatures can result in damaged leaves and stunted blooms. To ensure optimal performance, maintain temperatures above 50 degrees Fahrenheit.

High temperatures can lead to leaf wilting. It’s advisable to keep kalanchoe plants below 80 degrees Fahrenheit to prevent this issue.

Drab or Burned Leaves:
Proper light exposure is crucial for vibrant plants. Insufficient light can cause a loss of the characteristic glossy green in leaves, while excessive direct sunlight can lead to burned leaves. For indoor kalanchoes, choose a location with plenty of bright indirect light, avoiding excessive direct sunlight.

Soft, Fragile Stems:
Overwatering or planting in a water-retentive soil medium can result in soft, fragile stems and potential root and stem rot. If you notice signs of overwatering, refrain from watering until the plant recovers.

Failure to Bloom:
Kalanchoes may fail to bloom if they do not experience the necessary extended period of winter darkness. During the winter months, provide six weeks with nighttime darkness lasting a full 14 hours each day to reset the plant’s bloom cycle. Without this reset, the plants are likely to struggle to bloom again.
