watering

Red-hot poker (Kniphofia 'High Roller') should be watered around 1-2 times per week during the growing season. Make sure to water deeply so that the soil is evenly moist, but not soggy or waterlogged. Allow the top inch of soil to dry before watering. During winter, reduce watering frequency to once every 2-3 weeks and only when the soil is dry.

sunlight

Red-hot poker (Kniphofia 'High Roller') prefers direct sunlight, especially in the morning hours, for a minimum of 6-8 hours of exposure a day. This is best when the sun is closest to the horizon, helping create a well-rounded temperature and lighting schedule for these plants. If the sun is too intense, shading may be necessary to avoid heat stress. During the summer months, it is best to provide Red-hot poker with slightly cooler midday temperatures and more shade to help them thrive. In winter, the sun may be a bit weaker and a mulch will help to retain heat, acidity, and moisture.

pruning

Red-hot poker plants (Kniphofia 'High Roller') should be pruned in late winter or early spring before new growth begins. Pruning should involve cutting off all of the dead stems and leaves to about 10 cm (4 inches) from the ground. This will help to encourage vigorous new growth and flowering for the season. Such pruning also discourages disease and pests, ensuring a healthier and longer-lasting plant.
