Lobelia Propagation from Seed

Plant Lobelia seeds indoors early in the spring, or sow directly into the moist soil outdoors after all danger of frost has passed. Germination time is 14 days at consistently warm (70 degrees Fahrenheit) The seeds can germinate at lower temperatures, but it can take quite a long while. If sowing indoors, allow a couple of months for seedlings to become mature enough to be transplanted outdoors several weeks after the last frost.

Lobelia Propagation from Cuttings or Division

If you have a lobelia plant that you are especially fond of, you may wish to try growing more by cuttings or division. If the parent plant is growing outdoors, relocate it to a cool, protected spot indoors early in the autumn. It should receive lots of light but sparse watering through the winter.

In February, move the Lobelia seedlings to a warmer setting. Continue watering and watch for new growth. When it appears, take cuttings and plant them into small pots containing sandy soil or pure sand. They should develop roots shortly. When this happens, move your cuttings to more permanent containers with good quality soil.
