These hardy plants grow very well in containers if they receive plenty of light and have very well-draining soil. The pot must have drainage holes that allow water to drain freely. Because edelweiss stays quite small and is a slow-grower, repotting is not often needed. When edelweiss outgrows its container, gently loosen the roots from the container until they slide out. Place the plant into a slightly larger container and cover the roots with well-draining soil.
