Plant in well-drained soil and allow to dry out completely before transplanting into a pot. Plant in a location with good drainage. Do not plant in soil that is too wet or too dry, as this can lead to root rot.

Do lobelia seeds need light to germinate?
Do not cover seeds with soil, but gently firm the planting medium down with your fingertips after seeding. Seeds require light to germinate. A bright light and a well-ventilated area are what you’ll find in a location with a grow light. Do not place seeds in direct sunlight. Plant seedlings in an area with good drainage and good air circulation.
If the soil is too wet or too dry, the seedling may not be able to root properly, and the plant may wilt and die. The soil should be moist but not soggy, with no clay or silt in the bottom of the pot. Watering is not necessary during the first few weeks of plant growth, as the roots will take care of themselves.
However, after the plants have established roots, watering is necessary to keep them from drying out and to prevent root rot, which is a serious problem for many plants. It is best to water once or twice a week, or more often if the weather is hot and dry. When watering, do not allow the water to run off into the air. Instead, use a garden hose or garden sprayer to spray water directly onto the seeds.
This will keep the moisture from evaporating and will also help prevent mold and mildew.

What do you do for lobelia?
The soil needs to be kept moist at all times. Feed with an all-purpose, balanced food in the spring and early summer, then switch to a high potash feed in the summer. Cut back old flower stems after flowering and trim back new growth.
Fertilize in the fall and winter with a balanced, high-potash-based fertilizer, such as Miracle-Gro, or a low-nitrogen/high-phosphorus fertilizer. If you have a lawn mower, you can use it to fertilize your lawn, but be sure to keep the blades clean and free of debris.
How do you propagate lobelia?
Cut new growth that hasn’t yet flowered in the late spring. Remove any leaves from the plants. You can cut stem growth from the bottom of the plant to the top with your garden shears. This will allow you to harvest the lobelia as soon as it is ready to be harvested.
If you are growing a large number of loblolly pines, you may need to remove more than one piece of growth at a time. You can also use your fingers to pull the leaves off the stem. When you have removed all the growth, remove the entire plant and place it in a cool, dark, dry place for a few weeks to allow it to dry out.
The lobelias will then be ready for harvest. First, it can be cut into small pieces, which are then dried and used as a garnish. Second, lobels are harvested by cutting them in half lengthwise and placing them on a cutting board. Lobels should be dried for at least two weeks before being used to make garnishes.
