Lambs Lettuce
This week I have been in Nantes, Northern France, where the majority of our Lambs lettuce (also known as Corn Salad) comes from. This area is well renowned for production of Lambs and it exports over 30’000kg a year.
Historically, the Nantes region grew carrots but this has moved to the Bordeaux area and Nantes was looking for another crop. The area has plenty of water (Loire river) and a plentiful supply of sand. This sand is needed to cover the beds once drilling is completed. The benefits of this are threefold;
• Allows harvest cutting blade to get under plant meaning plant comes out whole
• Increases distance between soil and plant meaning reduced bacterial issues
• Water soaks into sand lowering humidity and quality issues
The sand used to come straight from the Loire, but this has been banned for environmental reasons, and the sand is now brought in by boat from further down the estuary.
Production is year round but concentrated in the winter. The crop is either grown in small or large tunnels, with either plastic for heat or green net for shading. The shading lowers the temperature of the sand in the summer, thus reducing scorch of the cotyledons.
