Sedum Gold Moss, also known as Sedum acre, is a popular succulent ground cover known for its low-growing foliage and ease of care. This hardy plant forms a dense, moss-like carpet of tiny, bright green to golden-yellow leaves, often topped with star-shaped yellow flowers during the summer months. It thrives in challenging conditions, making it a low-maintenance choice for various landscape needs.
Optimal Growing Conditions
Full sun exposure is ideal, promoting vigorous growth and intensifying its golden hue. While it tolerates some partial shade, especially in hotter climates, at least six hours of direct sunlight daily is recommended for optimal growth and bloom. Insufficient light may cause the foliage to lose its bright yellow tones and appear greener.
It is highly drought-tolerant once established, preferring infrequent watering. Overwatering can lead to root rot, so allow the soil to dry completely between waterings. During winter dormancy, it requires significantly less water, needing hydration only once every few weeks when the soil is entirely dry.
Well-draining soil is crucial. It adapts well to various soil types, including poor, sandy, or rocky compositions. While it can survive in clay soil, growth may be stunted and the risk of root rot increases due to poor drainage. An ideal soil pH ranges from slightly acidic to neutral, between 5.5 and 7.5.
Sedum Gold Moss is hardy in USDA Zones 3 through 9. It withstands cold winters and hot summers, typically preferring temperatures between 60 to 75 degrees Fahrenheit. Its drought resistance allows it to endure extreme weather fluctuations.
Planting and Placement
Choose a location with ample sunlight and proper soil drainage. Its adaptability allows it to thrive in less fertile conditions, suitable for areas where other plants might struggle. Prepare the planting area by ensuring well-aerated soil; for heavy clay, incorporate organic matter like compost to improve drainage.
Space Gold Moss Sedum 18 to 36 inches apart for mass planting, or closer for faster ground cover fill. It establishes easily from small plants or cuttings, which root quickly. For seeds, lightly press them into the soil surface without covering.
Sedum Gold Moss is versatile in landscaping. It serves as an effective ground cover, forming a dense mat that prevents soil erosion and suppresses weeds. Its low-growing, spreading nature makes it perfect for rock gardens, filling spaces between stones or spilling over walls. It also performs well in containers, hanging baskets, and between stepping stones.
Ongoing Care and Troubleshooting
Sedum Gold Moss requires minimal intervention once established. It rarely needs fertilization; in most cases, a thin layer of compost provides sufficient nutrients. If desired, a light application of balanced, slow-release granular fertilizer in early spring can promote vigorous growth, but too much nitrogen can lead to weak, floppy growth and increase susceptibility to rot. Pruning is minimal, primarily involving trimming overgrown or leggy stems to maintain appearance and encourage denser growth. This can be done after the blooming season or in early spring to stimulate new development.
It is generally resistant to most pests and diseases. While issues are rare, occasional problems like slugs, snails, or root rot from overwatering can occur.
Propagating Sedum Gold Moss is straightforward through stem cuttings or division. For cuttings, snip a healthy stem section, allow it to dry and callous for a day or two, then plant in well-draining soil where it will readily root. Dividing an established plant involves gently separating a rooted clump and replanting it in a new location, which also helps to rejuvenate the plant and prevent overcrowding.
