Sedum Planting Guide: Tips for Sedum Care, Propagation, Varieties, and Pest Management

This is a perennial plant. It gotn everything from succulent green foliage to beauty. It produces clusters of star-shaped flowers that bloom from midsummer to fall. It’s easy to care for and beloved by pollinators, too! Here’s how to grow Sedum in your garden.

Perennial plants couldn’t be easier than Sedum. This genus of succulents, also known as “stonecrop,” features fleshy stems and succulent leaves, making maintenance a breeze. Known for its hardiness, Sedum thrives in shallow soil, adapting well to various growing conditions. With a wide variety of Sedum available, there’s a suitable option for nearly every garden, making it a versatile choice for almost everyone- from gardeners to beginners having all levels of experience.

We divide Sedum into two main categories based on the plant’s growth habits: low-growing Sedum and upright Sedum.

Low-growing Sedum creeps along the ground, staying just a few inches tall or shorter. This makes them ideal for spreading out as a cover along walkways, in rock gardens, or draping over stone walls.

Tall or upright Sedum grows upwards, forming tall clumps with big flower heads packed tightly with small reddish-pink flowers. Their height and pretty flowers make them great for borders or gardens that attract pollinators. A while back, upright Sedum got moved to a different group called Hylotelephium, but people still often call it “sedum.”

How to Plant Sedum

How to Plant Sedum

Proper spacing and planting techniques ensure healthy growth and establishment when planting sedums, whether low-growing or upright varieties. Here are some guidelines to follow:.

Spacing

  • Space plants are between 6 inches and 2 feet apart, depending on the specific variety.
  • Low-growing sedums spread and fill gaps, while upright sedums typically maintain a more compact form.

Planting Full Plants or Divisions

  • Dig a hole deep enough so the top of the root ball is level with the soil surface.
  • Place the plant in the hole and fill it around.
  • Take care not to bury the stems of upright Sedum, as this may cause rotting.

Planting Cuttings

  • Sedum, like other succulents, can be easily propagated from cuttings.
  • Insert the cut end into the soil.
  • Ensure proper lighting and watering conditions for the cutting to root successfully.

Sedum Care

Sedum Care

Light is crucial for the well-being of sedum plants. They thrive in bright, direct sunlight, so placing them where they can soak up at least six hours daily is essential. While some varieties can handle partial shade, they won’t do well in low-light conditions. Generally, Sedum prefers full sun but can tolerate some shade if needed. In areas with cold winters, like Zone 5 and colder, it’s best to plant Sedum in full sun to help them withstand the harsh weather and improve their ability to survive through the winter.

Watering is crucial for sedum plants, as they thrive in well-draining soil. It’s best to water them when the top inch of soil feels dry to the touch. Overwatering can lead to root rot, so avoiding letting the plant sit in standing water is essential. During the winter, it’s wise to decrease watering frequency to prevent overwatering issues.

Soil: For optimal growth, sedum plants need soil that drains well. A blend of potting soil, perlite, and sand is ideal for proper drainage. It’s essential to steer clear of soil that holds onto moisture excessively, as this can lead to root rot. One of the great qualities of Sedum is its ability to thrive in less-than-ideal soil conditions, making it a perfect fit for rock gardens and arid landscapes.

Temperature: Sedum plants are remarkably resilient and can withstand various temperatures. They’re capable of surviving in frigid conditions as low as -30°F (-34°C) and enduring sweltering heat up to 90°F (32°C). However, Sedum may need more regular watering to thrive in hot and dry climates.

Fertilizer: Sedum plants don’t need to be fertilized often, but they can benefit from a balanced fertilizer application once or twice a year throughout the growing season.

Pruning: Sedum plants need little pruning, but you can shape them by trimming the top growth. It’s best to prune them in the spring or early summer before they bloom.

Recommended Varieties
