Growing Sedum Succulents in Cold Climates: A Comprehensive Guide

Sedum, commonly known as stonecrop, is a versatile and hardy succulent that thrives in a variety of climates, including cold regions. With their low-maintenance requirements and attractive foliage, sedums make an excellent choice for gardeners looking to add interest to their cold-climate gardens. Here's a comprehensive guide to help you successfully grow sedum in cold climates.

Choose Cold-Hardy Varieties:

   Not all sedum varieties are equally suited to cold climates. Opt for cold-hardy species such as Sedum spectabile (showy stonecrop), Sedum ternatum (wild stonecrop), or Sedum kamtschaticum (Russian stonecrop). These varieties are more resilient to colder temperatures and can withstand winter conditions. You will often find sedum in your local garden centre in the 'Alpine' section or you can find some like these ones on Amazon.

Selecting the Right Location:

   Sedums thrive in full sun but can tolerate partial shade. Choose a well-draining location with sunlight exposure for at least six hours a day. Cold-hardy sedums will appreciate a sunny spot, as it helps them store energy and withstand harsh winter conditions.

Soil Preparation:

   Sedums prefer well-draining soil. Amend your soil with horticultural sand, grit or perlite to enhance drainage. A slightly alkaline to neutral pH level is ideal for sedums. If your soil is heavy and tends to retain water, consider planting sedums in raised beds or containers.

Planting Sedums:

   Plant sedums in the spring or early fall. Dig a hole slightly larger than the root ball, place the sedum in the hole, and backfill with soil. Space plants according to their mature size, typically around 12 to 18 inches apart, to allow for proper air circulation.

Watering Practices:

   Sedums are drought-tolerant, but they still need water, especially during the growing season. Water deeply and allow the soil to dry out between waterings. Overwatering, especially in winter, can lead to root rot. Reduce watering in late summer to help sedums prepare for winter.

Winter Care:

   Cold-hardy sedums are well-suited for winter conditions, but a layer of mulch can provide extra protection. Mulch helps insulate the soil and prevents extreme temperature fluctuations. Apply a layer of organic mulch, such as straw or shredded leaves, around the base of the plants in late fall.

 Pruning and Deadheading:

   Remove spent flowers to encourage continuous blooming and prevent self-seeding. In late fall or early spring, cut back the dead foliage to tidy up the plants and promote new growth. Leave some dried flower heads intact to provide winter interest to your garden.

Pest and Disease Control:

   Sedums are generally resistant to pests and diseases. However, keep an eye out for aphids and remove them by spraying the plants with a strong stream of water. Ensure good air circulation to prevent issues like powdery mildew.


   Propagate sedums easily through division or stem cuttings. Divide mature plants in the spring or fall, replanting the divisions in well-prepared soil. Stem cuttings can be taken in the spring and rooted in a well-draining medium.

Enjoying the Benefits:

   Besides their aesthetic appeal, sedums attract pollinators like bees and butterflies. Their low-maintenance nature makes them an excellent choice for busy gardeners, and their ability to withstand cold climates adds versatility to your garden.
