☞ Sow the seeds indoors in late winter to late spring. Within 16 weeks, you will be able to see flowers on the plant.
☞ Make sure you sow 10-12 weeks before the last frost is due. Its seeds require temperatures above 65 degrees Fahrenheit.
☞ Wait till the seedlings are large enough to be handled. Transplant them into trays of potting compost and make sure that you space them at least 2 inches apart.
☞ When the danger of frost is over, you can transplant it by placing them at a distance of 4-6 inches from each other.
In case you are not sowing seeds, you could buy a plant from the garden supply store.
☞ Before you plant them in flower beds, you must replenish the soil with manure or fertilizers.
☞ Water them more often during the dry spells.
☞ Lobelia grows the best in cool spring weather. In midsummer, cut the plants and prune them to half their height.
☞ During the humid or hot weather conditions, you might see a decline in foliage growth and flowering. Pruning must be done at this time. You must also keep the soil moist.
☞ Once the weather changes, you might see beautiful flowers again on your plant.
☞ Another important aspect is pinching. Make sure that you pinch out the dead heads. This is to encourage branching and profuse flowering.
