Spring Pruning and Care for Red Hot Poker (Kniphofia)

Red Hot Poker (Kniphofia uvaria) — a perennial, not a shrub — benefits from annual spring cleanup and minimal ongoing care in California's Ventura County climate.

Annual Pruning

• Timing: Late winter/early spring before new growth emerges.
• Method: Cut all foliage to 2 inches above ground.
• Purpose: Removes winter-damaged leaves, stimulates fresh growth.

Water Basin ("Well") Practice

Creating a shallow basin (2-3 inches deep, 12-18 inches diameter) around the crown with mulch or soil helps capture water for deep root penetration — beneficial in dry climates but not essential with drip irrigation.

Ongoing Care

• Division: Every 3-4 years in spring to maintain vigor.
• Fertilization: Light application of balanced fertilizer in spring.
• Deadheading: Remove spent flower spikes to encourage rebloom.
• Winter care: In zone 9-10, no special protection needed.

These tough, drought-tolerant perennials thrive with minimal intervention once established.
