Naturally bog plants, so need to be kept moist at all times. Does not like hot, dry weather – rejuvenate in midsummer by cutting back by half their height, after the first flush of flowers has faded, which also will help them become bushier. Reapply fertilizer and water them well 2.
Try to plant in a location that enjoys partial sun / full sun and remember to water often. Use Zone 10 - Zone 10 as your guideline for the appropriate climate for this plant. Keep in mind when planting that Trailing lobelia is thought of as half hardy, so remember to protect this plant from frosts and low temperatures.

Sow in spring or autumn.
Sow seeds as thinly as possible – the finer you sow them, the easier pricking out will be. Lightly press the seeds into the compost/potting medium but do not cover them with soil as they need light to germinate. Place in warmth 15 to 20°C (60 to 70°F), and keep moist at all times 2.
In cooler climates it is also possible to start the seeds inside to get them off to an early flowering. Sow the seeds thinly into pre watered, compost filled trays.Firm in lightly but do not cover with compost. Top the tray with a sheet of glass or perspex or cling film and keep at15 to 20C. Remove the cover when the seeds germinate in 14 to 21 days
By our calculations*, you should look at sowing Trailing lobelia about 105 days before your last frost date .
When large enough to handle (usually after 5 to 6 weeks) transplant 5cm (2in) apart into trays of potting compost. It is easier to transplant little clumps of Lobelia seedlings than to try to transplant single seedlings 2. Keep the seedlings in a light, but cool, position, but shade from bright sun.
When all danger of frost has past, harden off the plants
Plant at 15 cm apart in final position, as the plants will spread 3.
Do not allow annuals to run to seed, as this will reduce the time that the plant will remain in flower

At the time I bought Petunia plugs I also bought Lobelia ‘Crystal Palace’ plugs. That was the name on the label but they turned out not to be trailing but bush ones. It didn’t say on the label but I was glad they were bush ones.They flowered non-stop all
