Even overwintering Lobelia plants indoors is no guarantee they will re-bloom in spring since these are short lived plants. Place them in indirect but bright light, away from drafts. Water them infrequently but check every so often, especially if they are near a heat source which will dry soil quickly.

Should I cut back lobelia?
Should I Prune My Lobelia? Yes. Cutting back lobelia plants improves their appearance and health. It also encourages the plant to produce more flowers over a longer period of time.
How do you care for perennial lobelia?
Perennial lobelia
Water Lobelia cardinalis plants whenever necessary to keep the soil or compost moist or damp. Feed with a general granular plant food each spring. Cut back old flower stems after flowering and the old foliage in autumn. Lobelia tupa may need some winter protection.
Can lobelia be grown indoors?
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.
How do you save dying lobelia?
If the dehydration is too severe, the plant may die. Water your lobelia in pots consistently so the soil stays moist and never draws away from the side of the container. If you let your hanging baskets dry out entirely, you may not be able to combat the resulting wilting and scorching by watering from the top.
What do you do with lobelia in the winter?
How to Overwinter Lobelia Annuals. In warmer zones, annual Lobelia can remain outdoors and will continue to bloom if cut back. Eventually, the plant will die out but should reseed. Northern gardeners will have to plant these Lobelias in containers and bring them indoors before any danger of frost.
How do you maintain lobelia?
Once established, the lobelia plant requires little maintenance. During hot, dry periods, care of lobelia requires that the plant should receive frequent watering, however, especially those in containers. A general-purpose liquid fertilizer can be given once a month or every four to six weeks, if desired.
Is Lobelia a sun or shade?
Annual lobelia is a cool-season plant that can tolerate most light conditions, including shade. Light: Shade, part sun, or full sun. Water: Plant in well-drained, moist soil. Size: Up to 3 feet tall.
How long does lobelia take to grow from seed?
The germination can take 14-20 days. Sow the seeds from February onwards, generally about 7 weeks before you want to transplant the seedlings. Placing the seeds into a polythene bag can aid germination by keeping these flower seeds warm and moist.
Can lobelia winter over?
Unlike its perennial cousins, annual lobelia dies back completely in the winter, though some types may grow from seed in the spring. Many annual lobelias are cold-tolerant and will survive longer into late fall or early winter than other types of annual flowers, but frost will kill them.
When can lobelia be planted outside?
When all danger of frost has passed and the seedlings have been hardened off you can plant them out where they are to grow, with a spacing of around 15cm.
