How to grow phacelia
Sow phacelia seed by scattering 1g of seed per square metre on the surface of your soil then rake and tamp down. You can also sow phacelia in rows 15cm apart.
If you are following a crop rotation system, phacelia can be grown within any of the rotations, and suits most soils.
Incorporating phacelia into your soil
Cut down or mow phacelia before digging it in before the plants set seed and at least four weeks before you need the soil for your next crop.
You can leave phacelia overwinter after the frost kills the leaves, however a severe frost may kill the plants too.
