you would be better not to plant leeks or any of the onion family near beans as the smell prevents the bees sussing out your bean flowers and you could have poor pollination. Sorry about your leeks this year, Pippa. I skipped them this year as my freezer still has a glut of leek and potato soup from last year but the self-sown ones look very healthy. My productive garden was designed for a family of nine, which we used to be, but now I am on my own I keep over-producing - so hard to adapt - and i don't get the same satisfaction from a bunch of my own flowers. My gardening "Bible" tells me that leeks will only grow well if they have uninterrupted growth and last year we had a late spring followed by a drought of about five weeks so the conditions were very poor for leeks.
