Keep the soil consistently moist until the seedlings emerge, which usually takes 7-14 days. Once the seedlings have two or three true leaves, they can be transplanted to individual pots or directly into the garden.
Propagation through Cuttings
Propagation through stem cuttings is another viable option for Lobelia cardinalis. Take cuttings from the plant in the spring or early summer. Select healthy stems that are about 3-4 inches long and remove the leaves from the bottom half of the stem. Dip the cut end in rooting hormone powder and then plant it in a well-draining soil mix. Place the pot in a bright, indirect light with a temperature of around 70°F (21°C).
Keep the soil moist and covered with a plastic bag or a dome-shaped cover until the cutting has rooted and new growth appears. Once the new growth has emerged, the plant can be transplanted into a larger pot or directly into the garden.
Propagation through Division
Propagation through division is a good option for mature Lobelia cardinalis plants that have formed a clump. In the spring, carefully dig up the clump and separate it into smaller sections, making sure that each division has enough roots and stems to survive. Replant the divisions in well-draining soil in a location with bright, indirect light. Keep the soil moist until the plant becomes established.
Propagation of Lobelia cardinalis L. ssp. graminea (Lam.) McVaugh is relatively straightforward and can be accomplished through seeds, cuttings, and division. Try different methods to see which one works best for you.
