Red Hot Poker Growing Tips

Light: Thrives in full sun, requiring at least 6 hours of direct sunlight daily. It can tolerate light shade but may produce fewer flowers. Needs protection from strong winds.

Soil: Prefers well-draining soil; tolerant of a range of soil types. Soil pH can be neutral to slightly acidic.

Water: Requires regular watering, especially during dry spells. Allow the soil to dry slightly between waterings to prevent root rot.

Fertilizer: Feed them with a balanced, slow-release fertilizer in the spring to encourage strong growth and flowering.

Pruning: Deadhead spent flower spikes to encourage more blooms. Cut back foliage in late winter or early spring before new growth begins.

Propagation: Propagate by dividing clumps in spring or fall.

Mulching: Mulch around the plants to retain soil moisture and suppress weeds. However, be careful not to mulch too heavily around the plant’s crown, as this can lead to rot.

Pests and Diseases: Generally resistant to pests and diseases. Watch for aphids, thrips, slugs, and snails. Root rot can be an issue in poorly drained soils.
