Planting
How to Grow
- Choose the sunniest, best-drained spot in your garden.
- Amend heavy clay soil with compost and grit to improve drainage.
- Dig a hole as deep and twice as wide as the pot.
- Place the plant in the hole, ensuring the crown is at soil level.
- Backfill with soil and water well.
- Avoid heavy mulching directly against the stem.
Pro Tip
Wait until you see new buds breaking on the lower stems in spring before pruning. This ensures you don't prune too early.
Keep It Thriving
Care Guide
Do
- Provide at least 6-8 hours of direct sun daily for best flowering.
- Allow the soil to dry out between waterings.
- Prune back hard in early spring to encourage a flush of new, flower-bearing stems.
- Choose modern, sterile cultivars to prevent unwanted seeding.
Don't
- Do not plant in shade or wet, heavy soil.
- Avoid over-fertilizing, which can produce lush leaves but fewer flowers.
- Don't prune in the fall, as the hollow stems can collect water and rot the crown.
- Do not overwater; they are very drought tolerant once established.
