Over the last 5yrs i have been growing in raided beds as my plot gets very wet and i have raised up 9ins,This year i grew BANDIT and an unnamed russian variety,the BANDIT were VERY good,the russian were 17ins of blanch,and very tasty, with both leeks i won 1st prize at my local show. I also grow Robinsons pot leeks also a prize winner. I start my leeks of the20th January in a propergator,I always use clover compost with added sand for drainage,by mid Feb the leeks are at crock stage and ready for potting up,i use clover compost and pot up in 24 cell trays, the better leeks i pot into 3ins pots for the show.
