Prepare
Position

Soil
When planted into the ground, Lobelia likes a free draining soil that is rich in organic matter. To improve the organic content in your soil, break up the soil and add Kings Compost and Kings Sheep Pellets then mix together well. When growing in containers, plant into Kings Container mix. This mix contains added water storage crystals and Saturaid, two products that help maintain moisture in the soil.
Plant
Lobelia can be sown directly into the garden, raised beds or containers that are at least 30cm deep. Or sown into a seed tray with Seed raising mix and transplant out once they are about 4 cm in size. Gently remove the seedling from the tray and plant. Space plants 30cm apart so they have plenty of space to grow. Take care when transplanting so that the young soft roots are not damaged. Gently firm the soil down after planting and water in well with Aquaticus Garden Booster, this will help the seedlings settle in.
