Kniphofia, also called torch lily or hot poker, makes a show in a garden, with flower-spikes in cream, yellow, red and orange. Depending on the species, the flower stems range in height from 24-inches to over 6 6 feet. A native of South Africa, Madagascar and Yemen, this perennial grows in U.S. Department of Agriculture plant hardiness zone 5 to 10. Easy-to-develop kniphofia tolerates most soils, even though it prefers a moist, well-draining soil. Fertilizing redhot poker advances the profusion and the look of blooms.
Before planting red-hot poker enrich the backyard soil 8 weeks. Spread 2″ of well-rotted compost or manure on the very top of the backyard and till it in to some depth of 6 to 8″.
Kniphofia subsequent to the flower exhibits indications of progress and has settled to the backyard. A total plant-food — both granules or liquid — in spring. In the event the plant-food isn’t slow repeat introduced.
Apply a 2 inch layer of clean mulch across the bottom of the red-hot poker plant in fall, following the flowers fade. The soil is enriched by the mulch .
Feed the plant in the beginning of the period. When the kniphofia starts actively developing apply a total plant-food.
