Sowing Guide

Early Sowing/Module Sowing

Thinly sow the seeds on the surface of moist compost in trays, modules or pots.
Lightly firm the seeds into the surface of the compost however do not cover.
Place the container in a clear polythene bag and seal or place in a propagator. Germinate at the temperature suggested above. Do not exclude light as this will aid germination however avoid direct exposure to hot sun .
Once germination has started remove from the bag or propagator and place in a cooler but not cold location. Protect from frost.
When the seedlings are large enough to handle transplant into 7 - 10 cm pots.
Grow on in a frost free greenhouse or cold frame and plant out when all risk of frost has passed and the lobelia's are growing strong.
Harden off over 7 - 10 days before planting out.

Direct Sowing

It is advisable to start the plants indoors rather than sowing the seeds direct.

Growing On

Water the young plants well until established.
Lobelia's will benefit from being fed frequently with a balanced fertilizer over the summer months.
Water established plants well in dry weather as they dislike dry conditions.
If growing in hanging baskets or containers ensure the compost is kept moist.


Lobelia' s dislike dry conditions. If the plants dye back in summer due to drought, cut the plants back by half their size. Add fertilizer and water well. A second flush of flowers should grow again if the soil is kept moist.
