How to Grow and Care for Mint Succulent

The mint succulent, scientifically known as Plectranthus tomentosa, is a captivating plant cherished for its aromatic, velvety foliage. Commonly called the Vicks Plant or Succulent Coleus, it emits a distinct menthol-like fragrance when its leaves are touched or bruised. This plant combines the appeal of a fragrant herb with the low-maintenance characteristics of a succulent. Its succulent-like nature allows it to store water, contributing to its ease of care.

Mint Succulent Care Guide

Light Requirements

Mint succulents thrive in bright, indirect sunlight, receiving six to eight hours daily indoors. Placing them near a window that filters direct rays prevents leaf scorch. Outdoors, a spot with four to six hours of partial shade is suitable, protecting them from intense, prolonged direct sun. Insufficient light leads to leggy growth or pale leaves, indicating a need for a brighter location.

Watering Practices

Water mint succulents using the “soak and dry” method, allowing the top inch of soil to dry completely before rewatering. Overwatering can lead to root rot, so ensuring excellent drainage is important. During the active growing seasons of spring and summer, watering once a week is typically sufficient to keep the soil moist but not waterlogged. In winter, during its dormant period, reduce watering frequency to every two to three weeks to prevent moisture accumulation.

Soil and Drainage

Mint succulents require a well-draining soil mix, similar to what is used for cacti or other succulents. A mix that promotes good aeration and allows excess water to escape is ideal. Avoid heavy soils containing large percentages of clay, peat moss, or coconut coir, as these materials retain too much moisture. Ensure the pot has adequate drainage holes.

Temperature and Humidity

Mint succulents prefer temperatures ranging from 60 to 75 degrees Fahrenheit (15-30°C) and are sensitive to frost, with temperatures below 30°F being harmful. A moderate to high humidity level (50-80%) is beneficial. While they appreciate humidity, misting the leaves is not recommended as it can encourage fungal growth. Placing the plant on a pebble tray filled with water can help increase ambient humidity without wetting the foliage.

Fertilizing

Light fertilization is suitable for mint succulents, particularly during their growing season in early spring. Apply a diluted liquid fertilizer at half-strength once a year. Avoid over-fertilizing, as it can scorch the plant’s leaves. During the plant’s dormant phase in winter, withhold fertilization entirely.

Propagating Mint Succulents

Propagate mint succulents through stem cuttings. Select healthy stems 3 to 6 inches long and make a clean cut just below a leaf node. Remove the lower leaves to expose the node. Allow the cut end to callus for a few hours to reduce rot risk.

Place cuttings in water, ensuring nodes are submerged, or directly insert them into well-draining soil. Provide bright, indirect light and consistent moisture for establishment. Roots typically form within a few weeks, then new plants can be transplanted.

Common Problems and Solutions

Yellowing or drooping leaves often indicate overwatering or underwatering. Mushy, swollen leaves suggest overwatering and potential root rot, while shriveled, wilted leaves indicate underwatering. Adjust the watering schedule to allow the soil to dry between waterings.

Leggy growth, with stretched stems and sparse foliage, points to insufficient light. Move the plant to a brighter location with more indirect sunlight.

Common houseplant pests like mealybugs, spider mites, aphids, and whiteflies can be managed by wiping them off with rubbing alcohol or applying insecticidal soap. A reduced menthol scent suggests inadequate light or nutrient deficiency. Ensure sufficient bright, indirect light and adhere to a light fertilization schedule to restore its aromatic potency.

Pruning and Maximizing Scent

Regular pruning encourages bushier growth and prevents legginess. Pinching back growing tips stimulates new lateral branching, creating a fuller, more compact plant. Cuttings from pruning can be used for propagation.

Pruning also maximizes the plant’s aromatic properties, as new growth produces a stronger scent than older foliage. To release the menthol fragrance, gently brush or rub the leaves. This ruptures cells containing aromatic compounds, allowing their scent to diffuse.
