Hi Richard

I set my leeks away boxing day, leek growing can be confusing, if you cut away all the seeds from the flowering head you get grasses and pips, pips are small bulbils already growing a shoot from the top, plant them and you get a leek true to strain, plant a seed and anything can grow.
Grow in greenhouse to about end of May then plant out into raised beds, show is about 2nd week in September, prize for first in good show can be several thousand £.
