- Water the plants thoroughly after planting, and continue to water regularly throughout the growing season.
Ongoing Care
- Mulch around the base of the plants to help retain moisture and suppress weeds.
- Fertilize the Kniphofia in early spring with a balanced, slow-release fertilizer to encourage strong growth and flowering.
- Deadhead spent flower stalks to promote continued blooming throughout the season.
- In the fall, cut back the foliage to the ground to prepare the plants for winter.

To address these issues, be sure to monitor your Kniphofia plants regularly and take appropriate actions, such as applying insecticidal soap for aphids or using a fungicide to control powdery mildew.
