Growing flax for regenerative textiles

The research

This field lab involves growers who are part of an emerging network aiming to re-establish a regenerative textile (particularly linen) supply chain in the UK, with a particular focus in Scotland.

The trial’s main objectives are to ascertain how well flax grows in a range of soil types, measured by crop establishment and yield; and to compare the performance of 3 varieties in a range of soil types.

The secondary objectives are to explore factors which may influence the retting process (e.g. time retted, number of turnings, weather); and to compare the fibre quality of 3 varieties.

The benefits

• 80% of the world’s flax crop is grown in Belgium, France, and the Netherlands
• There is little contemporary research available on growing modern varieties in UK soil types and climates.
• This trial is the first small step in exploring a resurgence in flax production and processing in Scotland.
• If successful, it is hoped that it will lead to further trials on a larger scale, with a longer-term aim is of making a case for industry investment in specialist harvest and processing equipment. 

Trial design

There will be three main trial sites.  Each site will grow 3 replicates of each variety (Avian, Delta, Tango) on 10sqm plots, totalling 9 plots per site. Plots will be randomised in three reps. Seed will be sown in rows 125mm apart at a rate of ~10g/sqm.

None of these varieties are commercially available in the UK yet.

Other community growers will also be encouraged to take part in a wider, support trial. 

The field lab will follow the production process from seed to harvested crop; measuring establishment & yield and comparing these across varieties and sites.

The seeds for the trial are being provided by Elsoms Seeds.
