How to Grow Flamethrower Plant Outdoors

The Flamethrower plant, also known as the Red Hot Poker plant, is a striking perennial that produces tall spikes of bright orange and red flowers in summer. This plant is native to South Africa but can be grown successfully outdoors in many parts of the world. Here’s how to grow flamethrower plants in your outdoor space.

Choosing the Right Location

Flamethrower plants prefer full sun but can tolerate some shade. They need well-drained soil that is rich in organic matter, with a pH between 6.0 and 7.5. If your soil is heavy or clay-based, amend it with compost or sand to improve drainage. These plants also prefer slightly dry conditions, so avoid planting them in areas that are prone to waterlogging.

Planting Flamethrower Plants

Flamethrower plants are typically planted in the spring or fall when the soil is warm and moist. Dig a hole twice the size of the root ball and add a handful of bone meal or other phosphorus-rich fertilizer to the bottom of the hole. Place the plant in the hole and backfill with soil, pressing down firmly around the base of the plant. Water thoroughly after planting.

Watering and Fertilizing

Once established, Flamethrower plants require minimal watering. Water deeply once a week during dry spells, but avoid overwatering as this can rot the roots. Fertilize once a year with a slow-release balanced fertilizer or apply compost annually to keep the soil enriched.

Pruning and Maintenance

Remove spent flower spikes as soon as they fade to encourage more blooms. Cut back any damaged or dead leaves or stems in early spring before new growth appears. In colder climates, mulch around the base of the plant in late fall to protect against winter damage.

Pests and Diseases

Flamethrower plants are relatively pest and disease-resistant. However, they can occasionally suffer from aphids, spider mites, or powdery mildew. Treat with insecticidal soap or neem oil for insect problems and remove any affected leaves for fungal problems.

Propagating Flamethrower Plants

Flamethrower plants can be propagated by dividing established clumps in the spring or fall. Use a garden fork to carefully lift the plant from the ground, then divide it into smaller sections using a sharp knife. Replant each section at the same depth as the parent plant and water well.
