When to sow: March – May
Spacing: See below
Phacelia tips: Broadcast the seed directly onto well-prepared soil and rake in gently. Alternatively sow in drills 20cm apart so you can weed in between the rows with a hoe.
Phacelia is used both as a bee-friendly flower and a green manure. If growing as a green manure dig in the plants before they flower as they will start go woody once flowering.
