Sedum makinoi, also known as Japanese Stonecrop or Ogon Sedum, is a succulent perennial. It forms dense, low-growing mats of small, rounded leaves, making it a popular choice for ground cover or container arrangements. Its easy care contributes to its appeal.
Essential Growing Conditions
Light Requirements
Sedum makinoi performs best in bright, indirect light or partial shade. While it can tolerate full sun, especially in cooler climates, intense direct sunlight can cause its leaves to develop reddish edges or even scorch the foliage. Conversely, insufficient light can lead to leggy, stretched growth as the plant reaches for more illumination, and its vibrant color may fade. Aim for at least six hours of bright light daily to maintain its compact form and rich coloration.
Watering Needs
Proper watering is important for this drought-tolerant succulent. Allow the soil to dry out almost completely between waterings. Overwatering is a common problem and can lead to root rot. When watering, do so thoroughly until water drains from the bottom of the pot, then empty any standing water from the saucer. Underwatering can cause the leaves to shrivel or become less fleshy.
Soil Composition
Well-draining soil is essential for Sedum makinoi. A specialized succulent or cactus potting mix is ideal. You can also amend regular potting soil with materials like perlite, coarse sand, or pumice to enhance drainage and aeration.
Temperature and Humidity
Sedum makinoi prefers moderate temperatures, thriving in a range of 18°C to 24°C (65°F to 75°F). While it can tolerate some colder temperatures, prolonged exposure below 10°C (50°F) may lead to dormancy. The plant tolerates average household humidity and does not require high humidity. High temperatures combined with high humidity can create conditions conducive to disease issues.
Ongoing Plant Maintenance
Fertilization
Sedum makinoi does not require heavy fertilization and can tolerate nutrient-poor soil. If fertilizing, apply a balanced, diluted fertilizer sparingly during its active growing season (spring and summer). Over-fertilization can result in weak or leggy growth. Fertilizing once a month during the growing season is sufficient.
Pruning Techniques
Pruning is not always necessary for Sedum makinoi, but it can maintain its shape and encourage denser growth. Trim back any leggy or overgrown stems to promote a more compact form. Removing dead or damaged foliage keeps the plant tidy and healthy. Light pruning is best done during the growing season.
Repotting Your Sedum
Repotting is needed every two to three years, or when the plant has outgrown its current container. Signs include roots emerging from drainage holes or the plant becoming top-heavy. The best time to repot is in the spring. When repotting, select a slightly larger pot with drainage holes.
Propagation Methods
Propagating Sedum makinoi is a simple process, achievable through stem cuttings or division. For stem cuttings, select healthy stems 3 to 6 inches long. Remove lower leaves and allow the cut end to dry and form a callus for a day or two. Once callused, plant the cutting in well-draining soil, keeping the soil lightly moist until new growth appears. Sedum makinoi stems root readily even if simply placed on top of soil.
Alternatively, propagate by division. Carefully unearth a mature plant and gently separate the root ball into several sections. Each section should have roots and foliage. Replant these sections in well-draining soil at the same depth as the original plant, ensuring the top of the root ball is level with the soil line.
Addressing Common Problems
Yellowing leaves indicate overwatering. If leaves appear shriveled or thin, it points to underwatering. Leggy growth, characterized by stretched stems and sparse foliage, results from insufficient light. Moving the plant to a brighter location helps resolve this.
Common pests like aphids and mealybugs can appear. These can be managed by gently wiping them off or using a mild insecticidal soap. Ensuring good air circulation and avoiding overcrowding also helps prevent pest infestations and issues like root rot.
