Lobelias have been the most popular of all the edging plants. They are either dwarf, compact plants or trailers with tiny flowers that bloom from late Spring to Autumn. They are half hardy perennials but treated as half hardy annuals.
Germination Temperature (°F)
Keep Lobelias moist, do not over-watering.
Feed every 10 days in soil or every 5 days in soil-less compost. Use a liquid fertilizer containing more potash than nitrogen.
Sow seeds on surface of seed and cutting compost. Do not cover seed tray with newspaper. Seeds do not germinate all at once. When large enough to handle, transplant seedlings into small clusters in seed trays. Plant out when frosts have finished.
Propagate from early to mid Spring.
Lobelias thrive in sun or light shade. They can be raised from seeds and can also be grown in pots and hanging baskets mixed with other colorful flowering plants.
Always dilute fertilizer to maker's recommended strength. When Lobelias have papery markings on the edges of its leaves, it is because the fertilizer was too strong.
Introduce plants to outdoors gradually. Protect from frost if they are out at night. Do not keep the plants too dry or waterlogged. Remove stems which have turned brown from disease.
In window boxes, decorative pots, hanging baskets, wall baskets and over the edges.
Spray in the evening in hot weather.
Any reasonable soil.
Most plant cells look like little boxes full of green disks. The disks are called chloroplasts. Other organelles inside a plant cell include a nucleus (where the DNA is kept), a large central vacuole (where water and other materials are stored) and a complex internal skeleton or cytoskeleton made of various proteins.
