How to grow phacelia Sow phacelia seed where you want it to flower, in well-prepared soil in full sun. Water in dry conditions only. Thin to 30cm apart if growing as a cut flower. If growing as a green manure, dig the plants back into the soil before flowering. If you can, allow some plants to flower to provide food for bees and other pollinators.
