Planting
How to Grow
- Select a site with at least 6 hours of direct sun per day.
- Ensure the soil is well-drained; amend with grit if it's heavy.
- Dig a hole that is the same depth and twice the width of the pot.
- Place the plant in the hole, keeping the crown at soil level.
- Backfill with soil and water lightly to settle.
- Water only when the soil is dry to the touch once established.
Pro Tip
Do not fertilize or plant in overly rich soil, as this can cause the stems to become weak and flop over.
Keep It Thriving
Care Guide
Do
- Provide full sun for the darkest foliage and strongest stems.
- Use poor to average, well-drained soil.
- Leave the dried seed heads on the plant for winter interest.
- Cut back old stems in early spring to make way for new growth.
Don't
- Do not overwater; sedums are prone to root rot in wet conditions.
- Avoid planting in shade, which results in green foliage and weak stems.
- Don't use rich compost or heavy fertilizers.
- Do not cut back in the fall; the stems provide winter structure.
