Grow leeks from multisown modules: quicker, cheaper, easier, high yield

I have been multi-sowing many vegetables since the 1980s, and lately the method has become popular. No wonder in view of the money, time and space you save in propagation.
Then there is the benefit of companion cropping, because plants stay with their mates when planted and establish more quickly.
Another advantage is shallower planting, and easier harvesting.
Other veg you can multisow are listed on this page of my website https://www.charlesdowding.co.uk/learn/multisowing/

Best sowing date for leeks is mid spring, not too early or they many bolt/flower. I sowed these Philomene (Bingenheim Seeds) on 6th April.
