WaterRed hot poker plants, including the Kniphofia 'Dorset Sentry', prefer consistent moisture and should be watered deeply roughly every week, allowing the soil to dry slightly between waterings. During the peak of summer, they may require more frequent watering, especially in drier climates. Aim to provide at least one inch of water weekly; this translates to about 0.62 gallons per square foot per week. Adjust the quantity based on rainfall and temperature, as excessive water can lead to root rot.
LightRed hot pokers, including the Kniphofia 'Dorset Sentry', thrive best in full sunlight. They need at least six hours of direct sunlight daily to perform well and produce vibrant, healthy blooms. An ideal spot for planting would be a south-facing location that receives unfiltered sunlight throughout the day.
TemperatureRed hot poker plants are hardy, and Kniphofia 'Dorset Sentry' can generally tolerate temperatures as low as 10°F and as high as 90°F. However, they grow best when daytime temperatures are between 60°F and 75°F. Ensure that they are planted in an area with good air circulation to avoid foliage diseases.
PruningPruning red hot poker plants, like Kniphofia 'Dorset Sentry', is essential to remove spent flower stalks and encourage new blooms. Prune the faded flowers throughout the blooming season to maintain plant appearance. In early spring, cut back any winter-damaged foliage to make way for new growth. Pruning once a year is generally sufficient.
CleaningAs needed
SoilRed Hot Poker (Kniphofia 'Dorset Sentry') thrives in well-drained, fertile soil with a pH range of 6.0 to 7.0. Ideal soil mix should be a combination of loam, compost, and sharp sand to encourage drainage. A layer of mulch can be beneficial to maintain soil moisture and temperature.
RepottingRed Hot Poker does not require frequent repotting and can often be left undisturbed for several years. Repot only when the plant becomes root-bound, which typically occurs every 3 to 5 years, to refresh the soil and provide room for growth.
Humidity & MistingThe Red Hot Poker prefers average to low humidity conditions. High humidity levels are not necessary and this plant can thrive in the humidity levels typically found in outdoor environments.

Life cycleThe Red Hot Poker (Kniphofia 'Dorset Sentry') begins its life cycle as a seed, which, upon germination in the spring, develops into a small seedling. As it grows, the seedling matures into a clump-forming perennial plant with a fleshy root system. Throughout the growing season, it produces long, strap-like leaves and develops tall, upright flowering spikes. The striking blooms, typically in shades of yellow, orange, and red, appear in the summer and can attract pollinators such as hummingbirds and bees. After flowering, seeds form and are dispersed, and the plant may also be divided and propagated. During the colder months, the Red Hot Poker enters a period of dormancy, with foliage dying back, before re-emerging in the subsequent spring to repeat the cycle.
PropogationPropogation time
Early Spring
The most popular method of propagating Kniphofia 'Dorset Sentry', commonly known as Red Hot Poker, is by division. This should be done in the spring or early fall. To propagate by division, carefully lift the clump from the ground with a garden fork, ensuring you are keeping a good amount of the root system intact. Gently separate the clump into smaller sections, each with at least one growth point or fan of leaves. Replant these divisions promptly at the same depth they were growing before, spacing them about 18 inches (approximately 45 centimeters) apart to allow enough room for growth. Water the new divisions well to help establish them. This simple process helps maintain the health and vigor of the plants while increasing your stock.
