What is the phacelia plant used for?
Phacelia is effective at preventing nitrogen leaching and suppressing weeds, due to its fast establishment. Although not known as a deep rooted species, its dense zone of shallow roots are very good at conditioning the top 3-4cm of soil. It’s a good source of pollen and nectar for pollinators and other beneficals. Lacy phacelia is native to the US, very beneficial for pollinators and beneficial insects, and often included in wildflower mixes. It’s not especially toxic, but is not considered edible due to the calcium oxalate, and can sometimes cause skin irritation. It’s generally considered a keeper.Lacy phacelia may become weedy or invasive in some regions or habitats and may displace desirable vegetation if not properly managed. Please consult with your local NRCS Field Office, Cooperative Extension Service office, state natural resource, or state agriculture department regarding its status and use.Lacy phacelia may become weedy or invasive in some regions or habitats and may displace desirable vegetation if not properly managed.

What are the benefits of phacelia seeds?
It is suitable for most soil types and performs particularly well in dry conditions. Although phacelia does not fix nitrogen, it is an efficient nitrogen holder, taking up nutrients and returning them to the soil when dug in. It fits easily into crop rotations and can be grown before most crops. Phacelia is a fast growing, hardy annual green manure that establishes quickly and produces dense foliage. Its shallow but extensive root system helps to improve soil structure, while the leafy growth is effective at suppressing weeds. It is suitable for most soil types and performs particularly well in dry conditions.Phacelia: A fast-establishing cover crop with good top growth and a root system that suppresses weeds. A competitive crop with benefits for managing erosion, leaching and structure. Not entirely frost tolerant and unlikely to senesce fully over winter.Phacelia (Phacelia tanacetifolia) does not fix nitrogen but is a fast growing, high biomass , annual nitrogen holding crop. The flower is eye-catching, lavender to pale blue/white in colour and very attractive to bees.Phacelia produces good surface rooting which helps to keep the soil well drained and the crop is a good nectar source. The crop is often killed by hard frosts. Mustard helps with nitrogen capture and gives rooting benefits. The crop is largely killed by harsh frosts.
Why grow phacelia?
Commonly used by farmers and vegetable growers, it works well as a green manure because it’s fast growing and tolerates lower temperatures – it may even survive a mild winter. Phacelia doesn’t fix nitrogen to the soil like leguminous plants but it does hold on to nitrogen, which is then dug back into the soil.
