Siberian Aster Plant Care
Eurybia sibirica (L.) G.L.Nesom
Updated · Sources · How we source care data
Eurybia sibirica, commonly known as the Siberian aster or arctic aster, is an herbaceous perennial native to north western North America and northern Eurasia. It is found largely in open areas of subarctic boreal forests, though it is also found in a wide variety of habitats in the region. It is similar in appearance to Eurybia merita, but their ranges overlap only near the border between the US and Canada, where E. sibirica is generally found at higher elevations.

What Soil Mix Works Best for a Siberian Aster?
Well-draining sandy loam with added organic matter. Good drainage is essential for Siberian Aster to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Siberian Aster?
Feed Siberian Aster every 6 months during the growing season (spring and summer) with a balanced fertilizer diluted to the strength on the label.
Pause feeding in autumn and winter, when growth slows, and never fertilize dry soil — water first.

How Do You Repot a Siberian Aster?
Repot every 2-3 years in early spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.
How Do You Propagate a Siberian Aster?
Siberian Aster can be propagated through division, seeds. Similar propagation techniques also apply to compact aster plant care, which shares the same genus.
Is the Siberian Aster Toxic to Pets and Children?
