do I best grow my leeks?
what depth should I plant leek plants? Some say the deeper the better.
And what pH do they like to get white fleshy stalks?
leeks when they are 15-20 cm long and the thickness of a pencil.
Make the hole 10-15 cm deep. Plant the seedling so that the roots
are just resting in the bottom of the hole and leaves just showing
above the soil surface. Do not firm in water in the seedlings
and as the soil settles it will fill in the hole and hold the leek
plant firmly in the ground. Plant leeks in a soil with a pH of 6-6.5.
Lovely white stems are
formed by earthing up (or mounding) around the leeks as they grow
this is not essential, but leeks are certainly much more
delicious when grown this way.
