How to Propagate Red Hot Poker
Growing Red Hot Poker From Seed or Roots
It may be possible to grow Red Hot Poker from collected seed. However, there are a vast array of available cultivars. These cultivars may have mixed or uncertain parentage. This is because they are bred from the wide variety of ornamental species of the genus. For this reason, seeds may not grow true to the parent plant.
To grow the Red Hot Poker variety you want, grow seeds of a named variety purchased from a nursery or garden center. Germination is said to take place in 21 to 28 days at 70° to 75° F.
In addition to seed, the garden center may have bare roots of Red Hot Poker available. These, you can grow on yourself. This saves a substantial amount of time and is also cost-effective compared to buying fully grown perennials.
In spring, plant the rhizome in soil just up to its neck, leaving the crown of the plant exposed. Water well while the Red Hot Poker Plant becomes established.
Growing Red Hot Poker from the Division of the Rhizomatous Roots
If you or a friendly gardener have Red Hot Poker plants, it is a great idea to divide these plants every few years. This refreshes the perennial from becoming overcrowded. Simply dig up the plant and tickle the roots apart. Extra roots can be planted in new areas of the garden or given away to other adventurous gardeners.
Red Hot Poker Diseases and Common Pests
Red Hot Poker is generally disease- and pest-free. Particularly when grown in well-draining soil in full sun in zones 5 to 9. Slugs and snails in abundance may be an issue for these plants. If soil is poorly draining, Red Hot Poker is susceptible to root rot.
