How do you deadhead lobelia?

If deadheading the flowers on the individual stems, head them back toward the base, so they aren't sticking up above the foliage. Snip at an angle, so water will run off the cut if it rains. Alternatively, shear back the entire plant by half once the flowers have finished blooming and begun to dry out in midsummer.

How do you overwinter lobelia?

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.

Seeds, when dried before planting stand a better chance of germination as the drying process hardens and seals the protective coat around inner parts. Seeds should be dried for 2 – 3 weeks in indirect sunlight on a clean surface. Dried seeds can be stored for up to 5 years under the right conditions.
