Introduction: Home Growing. Lobelia Flower on the Windowsill.
Growing Lobelia Plant
Lobelia seeds can be sown directly indoors. These plants typically require an area with full sun but will tolerate partial shade. They also prefer moist, rich soil. Start indoors about 10 to 12 weeks prior to the last frost in your region. Spread the tiny seeds just on top of the soil and water thoroughly. Place them in a warm, well-lit area.
The seedlings should pop up within a week or two.
Care of Lobelia Plants
Once established, the lobelia plant requires little maintenance. During hot, dry periods, care of lobelia requires that the plant should receive frequent watering, however. A general-purpose liquid fertilizer can be given once a month or every four to six weeks, if desired.
Lobelia should delight you with beautiful blooms about mid-summer, continuing on up to the first frost. Although not necessary, you can deadhead lobelia plants to maintain a neat appearance.
