Phacelia

Phacelia, a flowering plant valued for its multifaceted benefits, serves as a quick growing cover crop and green manure or as a sanctuary for pollinators and predator insects to feed and plan their assaults from. 

Phacelia’s ability to attract beneficial insects like bees and other pollinators with its vibrant flowers is due to the abundant nectar with carbohydrates for energy and protein-filled pollen for egg production, assisting biological control. Phacelia is utilised in companion planting strategies to improve pest management by attracting beneficial insects that prey on crop-damaging pests. A fabulous plant to have in your garden to support biodiversity and ecosystem resilience.

When employed as a cover crop, phacelia proves instrumental in enhancing soil health by preventing erosion and suppressing weeds with its dense foliage. Its deep root system aids in soil aeration and nutrient cycling, contributing to improved soil structure and fertility. Phacelia is a good phosphate scavenger, absorbing phosphate from deep down the soil profile and making it available for following crops. 

This versatile plant serves as a source of forage for livestock, providing a nutritious feed option.  Furthermore, it can be grown as an ornamental plant, beautifying landscapes and gardens while attracting pollinators. With its ecological benefits, forage value, and ornamental appeal, phacelia emerges as a valuable asset in the garden and in sustainable agricultural systems aimed at enhancing soil health, biodiversity, and crop productivity.

Sow from September through to April and dig or plough in any time.

North Island: You can sow slightly later (April–early May) due to milder winters.
South Island: Aim for March–April to allow enough establishment before cold sets in.
