  • The leaves make a fine addition to soups and casseroles etc, and I like nicely blanched leek stems steamed with a little seasoning as an accompaniment to fish dishes.

Maintaining Ecobed Productivity. 

  • Check out my blogpage which explains how I maintain productivity in my Ecobeds.  It describes how soil is prepared prior to planting, the importance of rainwater in Ecobeds, how to regulate the sun's intensity and how to feed plants through their leaves.

Growing Instructions.
  • Sow your leeks in punnets in an EcoPropagator, and when the seedlings are about 200mm tall, plant them in the prepared bed. 
  • Use string lines to mark out rows 150 mm apart, and plant the seedlings at 150 mm intervals along each row.
  • Make a hole for each seedling about 100 mm deep with a dibber and plant the seedling so that about 1/2 of the stem is visible above the surface.
  • Backfill with soil and water them in with dilute seaweed extract (suppliers dilution rate).
  • Apply fresh mulch around the leeks in spring as the weather warms up.
Harvest and Storage
  • If any of your leeks run to seed prematurely, nip off the seed heads as early as possible. 
  • Harvest leeks when they are big enough to use in the kitchen.
  • Cut them off at ground level and leave the roots to decompose in the soil.
  • They don't store well so harvest them as required.  
Organic Pest Control.
  • Leeks, like most vegetables, are vulnerable to attack from certain pests in my garden.  My blog on "Controlling Garden Pests" explains a little about these pests and what to do to protect plants from them.  For details click on the appropriate link below.
  • Slugs and snails.
  • Aphids (blackfly).
