What is the best type of medium to plant lilies in when force starting indoors before moving into the garden?
You could try planting your lilies in a warm sunny position, like a glass house, windowsill of a conservatory etc.
Use John Innes No3 mixed with a multipurpose compost ensuring the pot has drainage holes. You can then feed your lilies with a diluted tomato feed.
Water regularly.
