How to Grow Lobelia

Perfect for containers and baskets for summer colour, Lobelia is a half hardy annual that comes in a variety of colours, traditionally purple, blue and white.

For trailing plants try growing ‘Sapphire’ with beautiful blue blooms, and for edging grow ‘White Lady’ which has striking white flowers.

When to Sow

Seed should be sown undercover between January and March in trays of Gro-Sure Seed & Cutting Compost.

How to Sow

Keep warm, around 15-20c (60-70f). When large enough to handle transplant to pots of  Westland John Innes No1 Young Plant Compost. It is easier to transplant clumps than individual plants.

Once seedlings are established gradually acclimatise to outside conditions for several weeks before planting out after the risk of frost has passed.

Care

Feed plants regularly during summer using Gro-Sure All Purpose Plant Food. Plant will flower between July and September.
