Fountain crimson is slightly less vigorous than other varieties of trailing Lobelia. It produces masses of tiny flowers throughout the summer. Once your Lobelia plants are established, use 5 to fill a 12" or 30cm hanging basket.
These Lobelia mini-plugs will need pricking out into small 5cm pots or seed trays with inserts. Grow the plugs on in a heated greenhouse or on a sunny windowsill. They need to be kept at a minimum temperaturte of 7 degrees celsius. When the plugs are in the early growing stages, we recommend keeping them quite dry to encourage root growth. However it is very important not to let them dry out completely. The compost should be kept moist, not waterlogged, but also not dry and dusty.
Once the risk of frost has passed your plants can be planted out in the garden. Water your Lobelia regularly to prevent it from drying out. Watering is best done in the morning or evenings instead of when the sun is at its strongest to prevent the leaves from being scorched. Feed weekly whilst in flower with a good quality multi-purpose feed.
