Watering

Keep Lobelias moist, do not over-watering.

Feeding

Feed every 10 days in soil or every 5 days in soil-less compost. Use a liquid fertilizer containing more potash than nitrogen.

Germination

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.

Propagation

Propagate from early to mid Spring.

Cultivation

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.

Tips

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.

Care

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.

Decorate

In window boxes, decorative pots, hanging baskets, wall baskets and over the edges.

Humidity

Spray in the evening in hot weather.

Soil

Any reasonable soil.
