Lobelia (Lobelia erinus) is a dainty little trailing plant that comes in shades of blue, purple, lilac and white. They are easy to grow annuals that provide a great ground cover or contrast in rockeries, garden edges, pots and hanging baskets.


How to grow Lobelia in a garden

Starting from a seedling or potted plant:

  1. Choose a position with full sun or part shade with well-drained soil.
  2. Enrich the soil with Yates Thrive Natural Blood & Bone with Seaweed.
  3. When planting into prepared garden bed, ensure seedlings are well spaced – at least 10cm apart.
  4. Dig the planting hole twice as wide and to the same depth as the root-ball. Remove the plant from the container. Position in hole and backfill, gently firming down. Form a raised ring around the plant, creating a well so that water will go where it’s needed most. Water in well.
  5. Water in gently and keep soil moderately moist at all times.
  6. Mulch with an organic mulch such as bark chips, woodchip or pea straw to a depth of 5 - 8cm, keeping it away from the base of the plant.
  7. Feed with Yates Thrive Rose & Flower Granular Plant Food. TIP: for an added boost, apply Yates Thrive Roses & Flowers Liquid Plant Food.

Starting from seed:

  • Fill starter pots or trays with Yates Black Magic Seed Raising Mix. Sow seeds, lightly cover with a 1mm layer of mix, firm down and gently water in well. Keep moist at all times and place in a warm and sheltered position until seedlings have grown to 5 cm tall, then plant into the garden.
  • Alternatively, sow direct where they are to grow in rows or in scattered clumps around the garden. Cover with a 1mm layer of Yates Black Magic Seed Raising Mix. Lightly firm down and keep moist. Just be sure to enrich the soil with Yates Thrive Natural Blood & Bone with Seaweed prior to sowing.
