Tips for Growing Leeks Successfully

  • Some gardeners say leeks grow like weeds.  They are hardy and do not require a lot of caring in order to grow.
  • But you can only expect the best from your crops only when you do take care of it.  Follow these tips so you can harvest the freshest and best-tasting leeks.
  • Leeks can tolerate almost any type of soil but they grow best when sown in light, firm and moist soil.  It would also be better to plant them in an area where the ground has been manured or fertilized from the previous crop.
  • If your soil is too heavy, you can add organic matter to help it retain moisture.
  • Leeks grow best when planted in the place where lettuce, cabbage or peas has been grown.  However, never plant leeks immediately after the mentioned crops have just been harvested, especially, if the previous crop has been potatoes.  The soil would be too loose by then and leeks thrive better on firm grounds.
  • Never plant leeks in the same spot each and every time you grow them.  This would make them susceptible to diseases and pests.
  • Timing is also important when growing leeks.  They must be sown indoors about 12 weeks before the last spring frost.  This is applicable in areas with a cold climate.  Transplant them outside when the temperature steadily stays above 40 degrees F.
  • Leeks are grown for the white, tender part at its base that has not been exposed to the sun.  To make the white part bigger, you will need to “blanch” them.  To blanch, you can plant them in a furrow or trench.  Just cover the roots with enough soil.  As the leeks grow, continue adding soil to it until it is in level with the ground.

You can also plant leeks as you would other plants.  As they grow, you can mound more soil or straw at its base.

  • Provide leeks with at least an inch of water every week.
  • Leek have a shallow root system, so keep it free from weeds and take care not to plant other crops too close.
