Kniphofia is a sun lover that likes it hot and dry, though a good supply of water is appreciated when blooming. It can be grown in any well-drained soil.

Kniphofia is evergreen in mild regions and herbaceous in cooler zones. In both areas, it will benefit by having its leaf tips trimmed in the spring to stimulate healthy, new growth. In zones 4-6, the foliage can be tied up over the crown of the plant in the fall to exclude water from settling there and freezing, which would be deadly.

Growing Temperature:

65-68° F

Holding Temperature:

50-60° F

Soil PH:

5.5-6.5

EC (What is EC?):

2.0-3.0

Fertility:

Feed with a moderate rate of 100-150 ppm N at each watering.

Vernalization:

Cold beneficial but not required. If desired, provide 6-8 weeks of temperatures below 45° F.

Pests & Diseases:

Aphids, spider mites and thrips are the most common insects growers are likely to see during production. Rust, Alternaria, Botrytis and Sclerotium are the most common diseases to infect kniphofia.

Potting & Timing:

Late summer planting of small plugs is best. Bare root works well for spring planting.

Moisture:

Moderate moisture is best. Media can be allowed to dry slightly between waterings.

Planting Level:

Crown level with soil line.

PGRs/Pinching:

Spray applications of 30-45 ppm paclobutrazol (Bonzi, Paczol or Piccolo) or 5-7.5 ppm uniconazole (Concise or Sumagic)
Multiple applications may be required.

Lighting:

Long day beneficial.
14-16 hour daylengths reduce the time to flower.
