Starting Lobelia Seeds Indoors
Lobelia seeds can very easily be started from indoors. These beautiful blue plants tend to grow in clumps. Lobelia can be used for medicinal purposes as well, most commonly asthma and food poisoning. They look best when planted as borders, along walk ways, also in pots and window boxes. Regardless of whether you are using them for medicinal purposes or to make your yard look beautiful, there are several different types to choose from. Starting your lobelias from seeds requires a little patience but it is well worth it in the end. Care for them after they have germinated is simple.
Starting from Seed
Starting your seeds indoors is not difficult. It must be at least 70 degrees for them to flourish. You should start the seeds at least 8 to 10 weeks before when you usually get your first frost. Fill your seed trays with a light seed starting mix. You will then lightly scatter the seeds over the top of the soil. Make sure you don’t cover the seeds, very lightly press them into the soil. Spray the seeds with water every day until they germinate. This could take up to 3 weeks. As soon as the seeds begin to surface, place grow lights above them. The grow lights should remain around 3 inches from the plants. Move the light with them as they grow. Continue to keep the seeds moist.
You will want to transplant your seeds when they have gotten to be at least 1½ inches tall. You will want to gather small clumps of the seedlings into separate 1 to 2 inch posts. Continue to keep them moist, but not overly wet. Once your little seedlings have grown up to be at least 3 inches high you should begin to let them get used to outdoor conditions. Set your plants into the shade each day. Start slowly then begin to work your way up where they are spending more and more time outdoors. Be sure to bring them in at night, especially when temperatures each below 50 degrees. After the threat of frost is gone you can finally plant your flowers outdoors. You should space the clumps around 10 inches apart. Make sure the soil is rich and they will be given partial shade. Apply mulch to help your plants contain moisture. You should give them 1 inch of water per week.
You should water your lobelias 2 to 3 times per week. Just often enough to ensure that the soil is moist at all times. To significantly diminish the chance of your plant freezing or getting damaged, during the winter months only water them once a week. Once a year you should use 10-10-10 NPK fertilizer for your flowers. Be sure to follow the directions on the back of the bag to ensure that you use it properly. Early spring is the best time to apply this to promote the growth of your flowers during their growing season. You can expect your flower to bloom the fall and summer months.
