Kalanchoe, a popular succulent, is celebrated for its vibrant, long-lasting blooms and relatively easy care. Companion planting involves growing different plant species in close proximity to foster mutual benefits. This practice can enhance the health of Kalanchoe and contribute to a more aesthetically pleasing and thriving garden environment.
Understanding Kalanchoe Needs
Kalanchoe thrives in bright, indirect light, though it can tolerate some direct sun, particularly in cooler climates or during morning hours. Too much direct sunlight can scorch its leaves.
Well-draining soil is essential for Kalanchoe, ideally a succulent or cactus mix, or a blend of potting soil with perlite or coarse sand. Clay pots can further aid drainage.
Kalanchoe is drought-tolerant and prefers its soil to dry out completely between waterings. Overwatering is a common problem and can lead to root rot. During spring and summer, watering every one to two weeks is sufficient, while in fall and winter, this can be reduced to every three to four weeks.
Kalanchoe prefers moderate temperatures, generally between 60-85°F (15-29°C), and low to moderate humidity. They are sensitive to frost and should be protected from temperatures below 55°F (13°C).
Benefits of Companion Planting
Companion planting offers several advantages for Kalanchoe and the garden ecosystem:
It helps deter pests, benefiting plant health.
It can improve soil health and nutrient cycling.
It maximizes garden space by utilizing different growth habits.
It contributes to weed suppression, as dense foliage can outcompete unwanted plants.
It can create beneficial microclimates, such as providing shade for roots.
It attracts beneficial insects and pollinators, supporting overall garden biodiversity and plant vigor.
Ideal Kalanchoe Companion Plants
Selecting companion plants with similar light and water requirements is crucial for a successful Kalanchoe garden.
Other Succulents
Other succulents are excellent choices due to their shared need for bright light and well-draining soil. Echeveria, Sedum, and Crassula, such as the Jade Plant, are suitable companions. They thrive under similar low-water conditions and add diverse textures and forms, aligning well with Kalanchoe’s needs.
Drought-Tolerant Herbs
Drought-tolerant herbs also make good companions, offering aesthetic appeal and potential pest-repelling qualities. Rosemary prefers full sun and well-draining soil, providing a contrasting texture. Thyme, thriving in full sun and dry conditions, forms a low-growing mat that helps suppress weeds. Lavender, known for its low water requirements and fragrant blooms, also complements Kalanchoe in a sunny, well-drained environment.
Ornamental Grasses
Low-water ornamental grasses provide fine texture and movement without competing for moisture. Drought-tolerant varieties like Blue Fescue (Festuca glauca) or Maiden Grass (Miscanthus sinensis ‘Gracillimus’) thrive in similar conditions. These grasses prefer full sun and well-drained soil, making them compatible with Kalanchoe. Their varied heights and forms create visually appealing layers.
Plants to Avoid Near Kalanchoe
Certain plants are not suitable companions for Kalanchoe due to incompatible care requirements. Plants that demand consistently moist soil or frequent watering, such as many common annuals or leafy greens, will not thrive alongside drought-tolerant Kalanchoe. Overwatering these companions would inevitably lead to root rot for the Kalanchoe. Similarly, plants that require significant shade or very specific soil pH levels that differ from Kalanchoe’s preference should be avoided. Aggressive growers with extensive root systems or fast-spreading habits can outcompete Kalanchoe for limited resources like water and nutrients. These incompatibilities can lead to stress or decline for the Kalanchoe, hindering its growth and bloom production.
Tips for Kalanchoe Companion Gardens
When designing a Kalanchoe companion garden, consider these tips:
Container vs. In-Ground: Container planting offers flexibility, allowing for easy relocation to optimize light exposure and protection from adverse weather. For in-ground planting, ensuring excellent drainage is paramount, possibly by amending the soil with grit or planting in raised beds.
Adequate Spacing: Ensure proper air circulation and prevent overcrowding as plants mature, which helps reduce the risk of fungal issues.
Watering: Focus on Kalanchoe’s low water needs, allowing the soil to dry out between waterings for all compatible plants.
Monitoring: Regularly check the garden for signs of stress, pests, or diseases to allow for timely intervention, maintaining the health of the entire companion garden.
