Growing Lettuce

Latest Update 18th July 2018.

Lettuce
  • Red Iceberg Lettuce are fast growing and compact.  They have a crisp texture and taste great.  
  • I have found them easy to grow all year round in our climate, although they need protection from the sun to stop them bolting in summer.
  • They benefit from the protection of pest exclusion netting in the warmer months especially to keep butterfles away.
  • I use a mulch of clean straw to protect lettuce leaves from bottom rot, which is usually caused by direct contact with moist soil.
  • Like most organically grown vegetables, lettuce is rich in vitamins, minerals and is a great source of dietary fibre.
  • We always eat it fresh from the garden on salads, in sandwiches and in wraps.

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.
Propagating Seedlings. 
  • Check out my blogpage which explains how I propagate seeds.
Propagation Plan.
  • Check out my blogpage which tells you when to sow seeds. 
Growing Instructions.
  • Sow 6 lettuce seeds each month in an EcoPropagator as a cluster in a 30 cell seedling tray.  Transplant them individually in 6 cells containing fresh compost when established but still small.  When ready plant them out into a prepared row in an Ecobed.
  • Clear a small space in the mulch for each plug and plant them as deep as possible at 250mm centres in a 1500mm long row.  Water them in well with dilute seaweed extract (suppliers dilution rate) in rainwater.
Harvesting and Storage.
  • Lettuce can be harvested all year round. 
  • When harvesting, cut the heads off the Lettuce at ground level and allow the roots to decompose in the soil.
  • Lettuce does not store well and should be eaten within a few days of harvest.
