RED HOT POKER CARE & PLANTING
How to plant: Kniphofia has dense rhizomatous roots and a clumping habit, and is most often grown from divisions and potted plants. Red hot poker prefers a site with full sun and well-draining soil. When growing red hot poker, plant in spring when all danger of frost is past.
Follow these steps, spacing plants 1-3 feet apart, depending on the variety:
- Loosen soil in the planting area.
- Remove the plant from its nursery container and loosen roots if potbound.
- Dig a hole slightly wider and deeper than the root ball.
- Place in the hole so the crown of the plant is level with the surrounding soil.
- Fill in the hole with soil, tamp down lightly to remove air pockets, and water well.
- Keep plants watered regularly until established.
Soil: Kniphofia tolerates different types of soil, but performs best in moderately rich, well-drained soil. Amend native soil with compost or other organic matter before planting and provide good drainage to prevent root rot.
Watering: Red hot poker is drought tolerant once established, but does best with moderate water. Avoid overwatering to prevent root rot.
Fertilizing: Kniphofia plants need little or no supplemental fertilizer as long as soil has been amended. If soil is poor, apply a slow release all-purpose fertilizer in early spring according to package instructions.
Mulching: Plants can be mulched around the base with compost or other organic matter to suppress weeds, retain moisture and provide nutrients. Avoid placing mulch too close to the base of the plant to prevent root rot.
Pruning: The grass-like foliage of red hot poker plant is evergreen or semi-evergreen, depending on the climate. Foliage will suffer winter damage in colder regions. When cutting back red hot poker leaves, prune back the old foliage in early spring before new growth emerges.
How to deadhead red hot poker plants: Remove spent red hot poker flower spikes down to the base of the plant to encourage rebloom and neaten the appearance.
