Plectranthus ‘Guacamole’ is a distinctive ornamental plant with vibrant foliage. Its broad, textured leaves have scalloped edges and striking variegation of chartreuse or yellow with avocado green splashes. Deep red stems complement the colorful leaves. Also known as ‘Guacamole’ Swedish Ivy, it is a vigorous grower suitable for containers or landscapes. While it produces small white to mauve flowers in summer, its appeal is primarily its unique foliage and ease of care.
Caring for Plectranthus ‘Guacamole’
Light Needs
This plant thrives in bright, indirect light. Partial sun, about 4 to 6 hours daily, enhances leaf color and variegation. Too much direct sun can scorch the foliage. Inadequate light causes variegation to fade and may lead to leggy growth.
Watering
It prefers consistently moist, but not waterlogged, soil. Water when the top inch or two of soil feels dry. Allowing the top layer to dry slightly between waterings prevents root rot. While it tolerates brief drought due to moisture stored in its leaves, consistent watering promotes optimal growth.
Soil and Potting
It grows best in rich, well-draining soil with organic matter. A quality, well-draining potting mix is recommended. Ensure pots have adequate drainage holes to prevent water accumulation and root issues. For container planting, a 12-inch container can accommodate two to three plants, allowing for a full display.
Temperature and Humidity
It prefers moderate temperatures, between 60-75°F (15-24°C). It is not frost-tolerant and should be moved indoors before cold weather. While it appreciates average to above-average humidity, it tolerates typical household levels. Keep the plant away from drafts and sudden temperature changes.
Feeding and Pruning
During the growing season, this plant benefits from regular feeding. Apply a balanced, water-soluble fertilizer monthly or every 4-6 weeks to support new growth. Pruning maintains a bushy shape and encourages fuller growth. Pinching back new shoots encourages side branches and a compact form.
Propagating Plectranthus ‘Guacamole’
Propagating this plant is straightforward, typically done with stem cuttings. Select a healthy stem and snip a section with several leaves. Remove leaves that would be submerged in water or buried in soil.
Cuttings root in water or a moist soil medium. For water rooting, place cuttings in a glass, ensuring nodes are submerged. For soil, insert cuttings into a well-draining potting mix. A warm environment with bright, indirect light encourages root formation. Once rooted, transplant cuttings into individual pots.
Addressing Common Problems
This plant is generally low-maintenance, but issues can arise. Leggy growth with elongated stems indicates insufficient light; move the plant to a brighter, indirectly lit location and prune regularly for bushiness. Fading variegation also points to inadequate light; more bright, indirect light restores vibrant coloring.
Drooping leaves signal underwatering; a thorough watering resolves this. Yellowing leaves can signal overwatering or nutrient deficiency. If soil is consistently soggy, adjust watering to allow topsoil to dry between waterings to prevent root rot. If not overwatering, a balanced fertilizer can address nutrient imbalances.
While not highly prone to pests, it can occasionally be infested by aphids, spider mites, and whiteflies. Regular inspection helps detect pests early. Organic treatments like insecticidal soap or neem oil are effective.
